All contributions must be of a sufficient quality to extend our knowledge in weed science.

The papers submitted should not have been published or communicated elsewhere. Authors will be solely responsible for the factual accuracy of their contribution. Manuscript should not carry any material already published in the same or different forms.

  • Style of Invited paper
  • Style of Research Article
  • Style of Research note

Format

Full length article should be suitably divided into the following sub-sections; ABSTRACT, Key words, INTRODUCTION, MATERIALS AND METHODS, RESULTS AND DISCUSSION and REFERENCES. The heading, introduction need not be mentioned in the text.

Title

The title of article should be informative but concise and should not contain abbreviations. It should indicate the content of the article essential for key word indexing and information retrieval. It should be set in small and bold letters. A good title briefly identifies the subject, indicates the purpose of study and introduces key terms and concepts. Title should not be started with the waste words like 'a study of', 'effect of', 'influence of' , 'some observations on', 'a note of' etc. The title should indicate preferably English name or most popular common name of the crops or organisms studied, wherever relevant. Scientific name can be given in abstract and introduction. Authority for such a name should be given at first mention in the text. A short title should be given for running headlines and should cover the main theme of the article.

Author(s) name(s) and affiliations

The name(s) of the author(s) should be given in small letters with sentence case separated by 'comma' or by 'and'. Institute name where the research was carried out should be given in italics. If authors are of different institutes, these can be mentioned by allotting number like 1, 2 or 3 as superscript over the name of author. The affiliation of such author may be given below of the corresponding author email address. Sometimes authors retire and change frequently and wish to give their current address, this should be given as foot note. Email address of main author or corresponding author should be given at the bottom.

Abstract

The abstract should contain at least one sentence on each of the following: objective of investigation (hypothesis, purpose, collection, result and conclusions). Give complete scientific name for plants or other organisms and full name of any symbol or abbreviations used. There is a need to mention place, name and priod of study in abstract. Emphasis should be given to highlight the results and the conclusion of the study. It should not exceed a total length of 200-250 words. Abstract should not have the words like 'will be explained or will be discussed'.

Key words

(5 6) should be given at the end of the abstract and should be arranged alphabetically. Each key word should be started with capital letter and separated by comma ( , ) from other words.

Introduction

Introduction should be brief and to the point, cover the problem and should justify the work or the hypothesis on which it is based. In introduction, a detail review is not necessary. However, to orient readers, important references about previous concepts and research should be given. It should briefly state the currently available information and should identify the research gap that is expected to be abridged through this investigation. Give preference to recent references from standard research publication unless it is of historical importance or a landmark in that field.

Materials and Methods

This part should begin with information relating to period/season/year and place of study, climate or weather conditions, soil type etc. Treatment details along with techniques and experimental design, replications, plot size etc. should be clearly indicated. Use of symbols for treatments may be avoided and an abbreviation should be fully explained at its first mention. Crop variety, methodology for application and common cultivation practices should be mentioned. Known methods may be just indicated giving reference but new techniques developed and followed should be described in detail. Methods can be divided into suitable sub-headings, typed in bold at first level and in italics at second level, if necessary.

Results and Discussion

Results may be reported and discussed together to avoid duplication. Do not mention and recite the data in the text as such given in the table. Instead interpret it suitably by indicating in terms of per cent, absolute change or any other derivations. Relate results to the objectives with suitable interpretation of the references given in the introduction. If results differ from the previous study, suitable interpretation and justification should be given. Repeated use of statements like 'our results are in agreement’ or ‘similar results were reported’ 'should be avoided. At the end of results and discussion, conclusion of the study should be given in 2-3 sentences along with suggestion for further study, if any. All statistical comparisons among treatments may be made at P=0.05 level of probability.

Acknowledgement

The authors may place on record the help and cooperation or any financial help received from any source, person or organization for this study. This should be very brief.

References

Only relevant and recent references of standard work should be quoted. Preference should be given to quote references of journals over proceedings or reports. In general, not more than 15 references should be quoted in full paper and 5 in short communication. However, in review article, emphasis should be given to quote more references with each valid statement/findings in the text. There is no need to give references for standard procedures of soil and plant analysis, and for routine statistical analysis in practice, only the methodology may be indicated. As a thumb rule, all the references quoted in the text must appear at the end of the article and vice-verse. It has been decided to use full name of the journal after the year 2011 onwards. Therefore, references should include names of all authors, year, full title of the article quoted, full name of the journal in italics (no abbreviations), volume number (in Bold), issue number (in brackets) and pages. For books, monographs, theses etc. full title in italics, publisher or university name, volume no., if any, and relevant page range or total no. of pages should be given. The list of references should be arranged alphabetically on author's names and chronologically per author. Author name should be started with surname and initial letter with capital letter. There is no need to separate author's initials by full stop but it should be given in capital letters without gap. Each author name should be separated by comma (,) and last author name by ‘and’.

Length

Full length manuscript should not exceed 4500 words including space required for figures, tables and list of references. Research note can be up to 2500 words, with not more than 2 figures or tables. One season/year data should invariably be presented as research notes only.

Units, abbreviations and nomenclature

For physical units, unit names and symbols, the SI system should be employed. Biological names should be given according to the latest international nomenclature. Upon its first use in the title, abstract and text, the common name of a weed should be followed by the scientific name (genus, species and authority) in parentheses. If no common name exists in English, the scientific name should be used only. At the first mention of an herbicide or other chemical substance, give its generic name only. Trade names should not be used. Biological and zoological names, gene designations and gene symbols should be italicized. Yield data should be reported in kg/ha or t/ha. All such letters such as viz., et al., in situ, ex situ, Rabi, Kharif, i.e., etc. should be italicized.

Tables and figures

Tables and figures should be concise and limited to the necessary minimum. We encourage the authors to set tables and figures at the appropriate places in the article but if it is not possible, the same may be given separately. The title should fully describe the contents of the table and explain any symbol or abbreviations used in it. The standard abbreviations of the units of different parameters should be indicated in parentheses. Vertical lines should not be given in the tables and horizontal lines should be used to separate parameters and end of the table.

Figures may be preferred in place of table. In no case the same data should be presented by both tables and figures. While presenting data through line graphs, vertical bars, cylinders, pie charts etc, the same should be preferred with black lines or bars having different clear symbols and shades. The graphs chosen with colours reproduce poorly and should not be given unless it became necessary.

Some useful tips

Avoid numerals and abbreviations at the beginning of a sentence. Don't use superscript for per hectare, ton or meter (kg ha-1 or t ha-1) instead use kg/ha or g/m2, t/ha, mg/g, ml/l etc. Prefer to mention yield data in t/ha only. If it becomes necessary, give yield in kg/ha but not in quintal. Don't use lakh, crores or arabs in text, instead give such figures in million. Only standard abbreviations should be used and invariably be explained at first mention. Avoid use of self-made abbreviations like iso., buta., rizo., etc. Don't use first letter capital for names of plant protection chemicals but it should be used for trade names. Use of treatment symbols like T1 T2 T3 etc. should be avoided. All weights and measurements must be in SI or metric units. Use % after double digit figures, not per cent, for example 10% not 10 per cent. In a series of range of measurement, mention the units only at the end, e.g. 3,4,5 kg/ha instead of 3 kg/ha, 4 kg/ha and 5 kg/ha. Nutrient doses as well as concentration in soil and plant should be given in elemental form only, i.e. P and K should not be given as P2O5 K2O. A variety may be mentioned within single quotes in italic such as 'Pusa Basmai', 'Kufri Sinduri' etc. Statistical data should be given in LSD (P=0.05) instead CD (P=0.05).

Authors are requested to see the recent issue of the journal to prepare the manuscript as per the journal's format.

Manuscript submission

Manuscripts must conform to the journal style (see the latest issue). Correct language is the responsibility of the author. After having received a contribution, there will be a review process, before the Chief Editor makes the definitive decision upon the acceptance for publication.

Peer Review Policy

All published articles in Indian Journal of Weed Science (IJWS) are subjected to rigorous peer review processes based on initial editor screening and anonymized refereeing by two referees. The ultimate purpose of peer review is to sustain the originality and quality of research work and filtration of poor quality and plagiarized articles. Peer review assures research quality.

Paper Publication Process –

  • Manuscripts are received online in the editorial office with the certificate that MS has not been sent for consideration in any other journals for consideration.
  • Manuscripts are checked by office for its style and pattern and for plagiarism. If plagiarism is more than 20%, it is not considered and sent back to author for revision and re-submission.
  • If MS is found fit at Editorial office in context to plagiarism and style and pattern, it is sent to Chief Editor for further processing.
  • If chief Editor find the MS suitable for consideration, he shall suggest two name of referees as reviewers either from editorial board or from other institutions of concern discipline for reviewing the MS.
  • Editorial Office shall send the MS for double blind review to the reviewers suggested by Chief Editor.
  • Comments of double -blind reviewers will be sent to corresponding author without disclosing the identity of the reviewers to address the comments and re-submission of MS.
  • In case, one reviewer rejects while other accept the MS, it is sent to third reviewer suggested by Chief Editor.
  • Revised MS is again sent to reviewers to see whether their comments are addressed suitably.
  • On agreeing by the reviewers, the MS is again sent to Chief Editors with comments of reviewers and reply of author to take the final decision.
  • The final decision of Chief Editor is communicated to authors.

Peer Review Policy

The practice of peer review is to ensure that only good science is published. It is an objective process at the heart of good scholarly publishing and is carried out by all reputable scientific journals. Our reviewers therefore play a vital role in maintaining the high standards of the (Indian Journal of Weed Science) Journal of Management and Research and all manuscripts are peer reviewed following the procedure outlined below.

Initial manuscript evaluation

The Editors first evaluate all manuscripts. In some circumstances it is entirely feasible for an exceptional manuscript to be accepted at this stage. Those rejected at this stage are insufficiently original, have serious scientific flaws, have poor grammar or English language, or are outside the aims and scope of the journal. Those that meet the minimum criteria are passed on to experts for review.

Authors of manuscripts rejected at this stage will be informed within 2 weeks of receipt.

Type of Peer Review

The (Indian Journal of Weed Science) employs double blind review, where the reviewer remains anonymous to the authors throughout the process.

How the reviewer is selected

Reviewers are matched to the paper according to their expertise. Our reviewer database contains reviewer contact details together with their subject areas of interest, and this is constantly being updated.

Reviewer reports

Reviewers are asked to evaluate whether the manuscript:

  • Is original
  • Is methodologically sound
  • Follows appropriate ethical guidelines
  • Has results which are clearly presented and support the conclusions
  • Correctly references previous relevant work

Reviewers are not expected to correct or copyedit manuscripts. Language correction is not part of the peer review process. Reviewers are requested to refrain from giving their personal opinion in the "Reviewer blind comments to Author" section of their review on whether or not the paper should be published. Personal opinions can be expressed in the "Reviewer confidential comments to Editor" section.

How long does the peer review process take?

Typically the manuscript will be reviewed within 2-8 weeks. Should the reviewers' reports contradict one another or a report is unnecessarily delayed a further expert opinion will be sought. Revised manuscripts are usually returned to the Editors within 3 weeks and the Editors may request further advice from the reviewers at this time. The Editors may request more than one revision of a manuscript.

Final report

A final decision to accept or reject the manuscript will be sent to the author along with any recommendations made by the reviewers, and may include verbatim comments by the reviewers.
Chief Editor's Decision is final
Reviewers advise the Editors, who are responsible for the final decision to accept or reject the article.

Special Issues / Conference Proceedings

Special issues and/or conference proceedings may have different peer review procedures involving, for example, Guest Editors, conference organizers or scientific committees. Authors contributing to these projects may receive full details of the peer review process on request from the editorial office.

Becoming a Reviewer for the (Indian Journal of Weed Science)

If you are not currently a reviewer for the (Indian Journal of Weed Science) but would like to be considered as a reviewer for this Journal, please contact the editorial office by e-mail at (editorisws@gmail.com), and provide your contact details. If your request is approved and you are added to the online reviewer database you will receive a confirmatory email, asking you to add details on your field of expertise, in the format of subject classifications.

Abstract:

The field study was undertaken during rainy season of 2012 and 2013 to evaluate the rice cultivars and weed management effects on weeds growth and yield of direct-seeded rice (DSR) cultivars. The associated weed flora include Echinochloa colona, Echinocloa crus-galli, Cynodon dactylon as grasses; Cyperus rotundus, Cyperus iria as sedges; Caesulia auxillaries and Eclipta alba as broad-leaved weeds. Bispyribac-sodium  + azimsulfuron (25 + 35 g/ha) + 0.25% NIS as post-emergence at 15-20 DAS was found to be most effective in minimizing weed density, biomass and in enhancing the weed control efficiency 40.9% and 38.0% during 2012 and 2013 at 60 DAS, respectively. The maximum rice grain, straw and biological yield was found with application of bispyribac + azimsulfuron (25 g + 35 g/ha) + 0.25% NIS as post-emergence at 15-20 DAS and was significantly superior over rest of the treatments during both the years of study.

Abstract:

A field experiment was conducted during Kharif 2015 and Summer 2016, at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka, India, to study the effect of different herbicides for control of weeds in irrigated dry-seeded rice. The dominant weeds in fields were Echinochloa sp. Panicum repens, Cynodon dactylon, Bracharia mutica, Digitarias anguinalis and Leptochloa chinensis among grasses, Eclipta alba,Commelina communis and Ludwigia parviflora as among broad-leaf weeds and Cyperus sp. as sedge. Among herbicidal treatments, post-emergece application of BAS 9548 H (penoxsulam 10 g/l + bentazone 360 g/l SC) 3000 ml/ha recorded significantly higher rice grain yield followed by the application of BAS 9548 (penoxsulam 10 g/l + bentazone 360 g/l SC) 2500 ml/ha and twice hand weeding at 15 and 30 days after sowing (DAS). The maximum B:C ratio was observed in plots treated with BAS 9548 H (penoxsulam 10 g/l + bentazone 360 g/l SC) and twice hand weeded check.

Abstract:

The experiment was conducted on irrigation levels and integrated weed management practices during 2013 and 2014 at College of Agriculture, Hyderabad. Results revealed that higher grain yield was recorded with scheduling of irrigations at IW/CPE ratio of 2.0 (2.55 and 2.42 t/ha) due to accumulation of higher chlorophyll content and dry matter production of crop. Net returns (` 20656 and 18347/ha) and benefit cost ratio (1.7 and 1.6) was also higher with the same irrigation level. Scheduling of irrigations at IW/CPE ratio of 1.5 was the next best treatment in aerobic rice. Out of weed management practices tested, application of pendimethalin/butachlor as pre-emergence fb chlorimuron-ethyl + metsulfuron-methyl  post-emergence fb MW + HW at 45 DAS recorded lower weed population, weed dry matter and higher in weed control efficiency, which resulted higher chlorophyll and dry matter accumulation in crop and finally produced higher grain yield in pendimethalin 1.0 kg/ha as PE fb MSM + CME 4.0 g/ha at 25 DAS + MW fb HW at 45 DAS (2.15 and 2.05 t/ha) and butachlor 1.0 kg/ha as PE fb MSM + CME 4.0 g/ha at 25 DAS + MW fb HW at 45 DAS (2.08 and 1.98 t/ha). The same treatments recorded higher net returns and benefit cost ratio in pendimethalin 1.0 kg/ha as PE fb MSM + CME 4.0 g/ha at 25 DAS + MW fb HW at 45 DAS (1.6 and 1.5) and butachlor 1.0 kg/ha as PE fb MSM + CME 4.0 g/ha at 25 DAS + MW fb HW at 45 DAS  (1.6 and 1.5). Over the pooled years, significant interaction effect of irrigation scheduling at IW/CPE ratio of 2.0 along with application of pendimethalin/butachlor as pre emergence fb chlorimuron-ethyl + metsulfuron-methyl as post-emergence fb MW + HW at 45 DAS recorded lower weed dry matter (35.1/36.4) and higher grain yield (2.85/2.80 t/ha).

Abstract:

A field experiment was conducted at KVK, South Tripura during the Kharif season of 2013 and 2014 to study the integrated weed management in direct-seeded upland rice. The predominant weed flora in the experimental field were Amaranthus viridis, Oldenlendia corymbosa, Spilanthes acmella, Ludwigia parviflora, Cleome rutidosperma, Malvestrum coromondalianeum among the broad-leaf weeds, Digitaria sanguinalis among grasses and Cyperus iria among sedges. The results revealed that though the hand weeding thrice at 15, 30 and 45 DAS recorded lowest weed dry weight and the highest grain yield, it was not economically viable. The pre-emergence application of pendimethalin at 1.0 kg/ha at 2 DAS + bispyribac-sodium at 25 g/ha at 20 DAS recorded the highest net returns and return per rupee invested and appeared to be the most promising and remunerative weed management practices for direct-seeded rice under Tripura condition followed by pendimethalin at 1.0 kg/ha at 2 DAS + one hand weeding at 30 DAS.

Abstract:

A field study was conducted in an Inceptisol with summer season rice to evaluate the degradability of different post-emergence herbicides applied alone or in combinations in terms of microbiological characteristics of rhizosphere soil. Five different herbicides (bispyribac-sodium, metamifop, chlorimurone-ethyl, metsulfuron-methyl and cyhalofop-butyl) were applied as an individual or in combination at post-emergence stage (15 DAS). A wetting agent (agrisol) was also used with some herbicides to increase the effectivity of applied herbicides. Application of different herbicides had inhibitory effect on microbial population and their activities in soil after application, but their effects were not pronounced and the soil properties were restored. Although herbicides applied at different rates but their degradability was almost equal and they took only 30 days or less period for complete degradation except cyhalofop-butyl and bispyribac-sodium + metamifop, which ware applied 80 g and 140 g/ha, respectively and found completely degraded before harvest.

Abstract:

A field experiment was conducted during 2011-12 and 2012-13 at G.B. Pant University of Agriculture &Technology, Pantnagar to study  the effect of different rates of pre-mix of pinoxaden 2.53% + clodinafop-propargyl 2.53% on population and growth of weeds and grain yield of wheat. Major weed species identified in the experiment were Phalaris minor, Avena spp., Chenopodium album, Anagallis arvensis, Polygonum plebeium, Melilotus indica, Coronopus didymus during both the years. The lowest density and biomass of grassy weeds were recorded with pinoxaden 2.53% + clodinafop-propargyl 2.53% at 60 g/ha. However, it was ineffective against broad-leaf weeds. Maximum grassy weed control efficiency (100%) was observed with pinoxaden + clodinafop-propargyl at 60 g/ha closely followed by its lower dose applied at 50 g/ha and pinoxaden at 50 g/ha. Pre-mix of pinoxaden 2.53% + clodinafop-propargyl 2.53% at 60 g/ha produced highest grain yield (4.5-4.6 t/ha). Uncontrolled weeds caused 55.7 and 52.2% reduction in grain yield of wheat when compared with weed free conditions during 2011-12 and 2012-13.

Abstract:

Sugarcane being a widely spaced crop offers considerable space for cultivation of short duration intercrop. In sub-tropical India, sugarcane planted in autumn accounts for higher productivity due to extended period (approximately 12–16 months) of vegetative growth, but its feasibility is only possible if some intercrop especially wheat in Rabi season is sown as it can help farmer in generating additional income in midway of sugarcane season. Two rows of wheat has already been recommended in the north – western India, but the success was marred due to lack of suitable weed control methods in sugarcane – wheat intercropping system. Twelve weed control treatments including ten applications with post-emergent herbicides i.e. sulfosulfuron 25 g/ha and 37.5 g/ha, pinoxaden 50 g/ha and 75 g/ha, readymade blend of sulfosulfuron + metsulfuron 30 g/ha and 45 g/ha, readymade blend of mesosulfuron + iodosulfuron 14.4 g/ha and 21.6 g/ha, metsulfuron 5 g/ha , carfentrazone-ethyl 20 g/ha, a weed free treatment with two hoeings at 3 and 6 weeks after sowing wheat (WASW) and an unweeded control (no hoeing and no herbicide application) were evaluated for three years from 2008-09 to 2010-11 in randomized block design with three replications. The objective of the experiment was to identify the best possible method of weed control for maximizing the productivity of sugarcane wheat intercropping system. All the chemical and cultural weed control treatments including the application of herbicides and manual hoeings suppressed the weeds efficiently as compared to the unweeded control. Among the herbicidal spray, application of sulfosulfuron 25 g and 37.5 g/ha recorded the lowest pooled dry matter of weeds and thus exhibited the highest weed control efficiency (mean of three years) (61.2% and 63.5%, respectively). The highest pooled cane equivalent yield of 92.7 t/ha was recorded with sulfosulfuron + metsulfuron 30 g/ha. Application of any herbicide at a higher dose than normal, could not supplement additional millable canes and sugarcane yield. Application of readymade blends of sulfosulfuron + metsulfuron 30 g/ha and mesosulfuron + iodosulfuron 21.6 g/ha produced pooled intercropped wheat yield of 3.41 and 3.49 t/ha which surpassed the 3.35 t/ ha of wheat yield achieved with two manual hoeings at 3 and 6 WASW. The cane quality was not affected by application of any herbicide.

Abstract:

A field experiment was conducted at College of Agriculture, Gwalior, India during Rabi (winter) seasons of 2014-15 and 2015-16 to evaluate the bio-efficacy of different herbicides to control diverse weed flora especially Phalaris minor in wheat. The experiment was laid out in a randomized complete block design, replicated three times, and consisted of 12 treatments including four treatment as pendimethalin (0.75 kg/ha) as pre-emergence (PE); sulfosulfuron (0.025 kg/ha), metribuzin (0.21 kg/ha), clodinafop (0.06 kg/ha) as post-emergence (PoE) used individually and six of different herbicidal combinations as pendimethalin + metribuzin (1.0 + 0.175 kg/ ha PE), pendimethalin + sulfosulfuron (1.0 + 0.018 kg/ha PE and PoE), sulfosulfuron + metsulfuron (0.03 + 0.002 kg/ha at 5 WAS), pinoxaden + metsulfuron (0.06 + 0.004 kg/ha at 5 WAS), mesosulfuron + iodosulfuron(0.012 + 0.0024 kg/ha at 5 WAS), clodinafop + metsulfuron (0.06 + 0.004 kg/ha at 5 WAS), weedy check and as two hand weedings at 30 and 60 DAS. The highest mortality of weeds and the maximum grain yield of 5.00 t/ha and 4.07 t/ha with 38.2%, 31.0% increase in grain yield over weedy check were recorded with two hand weedings at 30 and 60 DAS (weed free) followed by herbicidal combination as pinoxaden + metsulfuron (0.06 + 0.004 kg/ha at 5 WAS) as PoE application during 2014-15 and 2015-16, respectively. Whereas, the highest B:C ratio of (3.69) was obtained with pinoxaden + metsulfuron (pre-mix) followed by sulfosulfuron + metsulfuron (3.67).

Abstract:

An experiment on evaluation of herbicides in greengram and their residual effect on succeeding mustard crop was conducted at Research farm of Department of Agronomy, CCSHAU, Hisar during Kharif 2013 and Rabi 2013-14. Weed flora of the experimental field was dominated by Echinocloa colona (78%), Cyperus rotundus (18%) and other weeds (4%) at 30 DAS. Pre-emergence application of ready mix (RM) imazethapyr + pendimethalin at 1000 g/ha provided good control (80%) of Echinocloa colona up to 30 DAS. At 60 DAS, imazethapyr + imazamox (RM) at 80 g/ha applied at 3-4 leaf stage provided maximum control of weeds, which was at par with two hoeings employed at 20 and 40 DAS. Post-emergence use of imazethapyr + imazamox (RM) at 60-80 g/ha exhibited 70-80% control of weeds with slight crop suppression which mitigated within 10-15 days after spray resulting maximum  crop growth and  seed yield. Early post-emergence application of imazethapyr at 50, 60  and 70 g/ha although caused mild injury to greengram in terms of yellowing of leaves and stunted crop growth up to 30, but it diminished within two weeks. Maximum seed yield (1078 kg/ha) of green gram was obtained with two hoeings at 20 and 40 DAS followed by imazethapyr + imazamox (RM) at 80 g/ha and imazethapyr at 70 g/ha applied at 3-4 leaf stage. All herbicides, irrespective of their dose and time of application, did not cause any injury to succeeding mustard crop due to high rainfall (594 mm) during crop growing season that resulted in to enhanced microbial degradation of herbicides.

Abstract:

Earthworm population, soil organic carbon content and β glucosidase enzyme activity in the soil are considered as the indicators of soil quality and biomarkers for toxicity and bioaccumulation assessment. Hence, field experiments were conducted during first crop season (Kharif 2014) and second crop season (Rabi 2014-15) to study the impact of pre- mix herbicide mixtures bispyribac-sodium + metamifop and penoxsulam + cyhalofop-butyl on earth worm population , soil organic carbon content and β glucosidase enzyme activity in soil. The experiments were conducted in randomized block design with 12 treatments and three replications at Upaniyoor Padashekaram in Thiruvananthapuram district of Kerala, India. The treatments were bispyribac-sodium + metamifop at 60, 70, 80 and 90 g/ha, penoxsulam + cyhalofop-butyl at 120, 125, 130 and 135 g/ha, bispyribac-sodium applied alone 25 g/ha, penoxsulam applied alone at 22.5 g/ha, hand weeding twice and weedy check. All the herbicide treated plots registered earthworm population at par to weedy check and hand weeding. The organic carbon content in soil was higher in herbicide treated plots as compared to weedy check at all the stages of crop growth. Herbicide treated plots were comparable to non-herbicide treated plots with respect to glucosidase activity. It was concluded that the pre-mix bispyriibac-sodium + metamifop and penoxsulam + cyhalofop are environmentally safe.

Abstract:

Most of the farmers shifted to direct-seeded rice (DSR) from conventional puddled-transplanted system. One of the major challenges in DSR is weed management, which reduces the productivity of the rice system significantly. Therefore, many herbicide combinations are being tried for broad-spectrum control of weeds. In the present study, field experiments were conducted during Kharif 2013 and 2014 to know the herbicides efficacy when used in mixture using dose-response curve in DSR. The treatments comprised of tank-mix combinations of two herbicides viz. fenoxaprop (0, 30, 40, 50, 60 g/ha) and metsulfuron (0, 2.5, 3.0, 3.5, 4.0 g/ha) to control grassy and broad-leaved weeds, respectively in DSR. Among many non-linear dose-response models, hill model was found to be the best for the data. Results revealed that when fenoxaprop applied in mixture with metsulfuron, its efficacy increased/decreased 4-5% during both the years. Further, when metsulfuron was applied in mixture, its ED50 value was increased from 3.43 to3.62 g/ha as compared to its alone application. Thus, the study revealed the presence of antagonistic effect of fenoxaprop on metsulfuron when used in mixture, which ultimately resulted in reduced efficacy in terms of pre cent weed control.

Abstract:

Field experiments were conducted at Viswavidyalaya farm, Jaguli, Nadia following system intensification (SI) package of practices during 2011-2016 on pre-Kharif black gram (Vigna mungo) and green gram (Vigna radiata) – Kharif direct-seeded puddled and transplanted rice (Oryza sativa) – Rabi potato (Solanum tuberosum) and onion (Allium cepa) crop sequences. Balance nutrition of N:P:K:Neem cake at recommended doses were used along with judicious water in critical crop growth stages and ecosafe green labelled pesticides for insect and disease management. For annual planning of weed pest management (APWPM), glyphosate 71 SG + oxyfluorfen 23.5 EC mixture at 1000 g/ha was used after pre- Kharif crops besides the application of selective pre-emergence (PE) organic herbicides treatment wise in different crops along with HW, post-emergence (PoE) herbicides and weedy check as standard. The results revealed that PE herbicide treatments recorded 30.5 and 10.3% more productivity over PoE herbicides treated plots and 38.4 and 60.0% over weedy check in blackgram and greengram, respectively. The corresponding values were 2.74 and 5.14% and 32.7 and 31.0% in direct seeded puddled and transplanted rice, respectively. In Rabi potato and onion, these figures were 21.1 and 30.4% and 42.0 and 49.0%, respectively. The soil microflora population at harvest recorded increasing in all PE herbicide used plots though an initial decreasing trend upto a month.

Abstract:

The study was conducted to assess the allelopathic potential of three basmati (PR 115, PR 124, PR 118) and three non-basmati (Pusa Punjab Basmati-1509, Punjab Basmati-3 and Basmati-386) rice varieties against germination and seedling growth of Echinochloa crus-galli, E. colona and Phalaris minor. Shoot extracts (5%) of non-basmati rice varieties prepared from 50 days old plants had more detrimental effect on germination and seedling growth of E. crus-galli as compared to basmati rice varieties. Variety ‘PR 124’ reduced E. crus-galli germination to 10% and seedling vigor index by 95.8% as compared to control. Root extracts (5%) of basmati varieties had higher allelopathic potential against germination and seedling growth of E. crus-galli than non-basmati varieties. Root extracts (5%) of ‘Punjab Basmati- 3’ affected germination and SVI of E. crus-galli most severely. Aqueous extracts of rice varieties also significantly reduced germination of E. colona and P. minor.

Abstract:

The experiment on weed control in rice bean was conducted at Hebbal, Bengaluru for three years 2012, 2013 and 2014 using pre- and post-emergent herbicides along with manual weeding. Results revealed that the weed free control treatment recorded the lower weed count (11.11/m2), weed dry matter (10.6 g/m2) with higher weed control efficiency (95.3%) and seed yield (1.42 t/ha). The higher B:C ratio of 2.62 was recorded with pre-emergence application of pendimethalin 1.0 kg/ha + one hand weeding at 5 weeks after sowing (WAS) followed by pre-emergence application of oxyflurofen 50 g/ha + one hand weeding at 5 WAS (2.61).

Abstract:

This study was conducted with the aim to understand the effects of tillage practices and Rabi crops on weeds in rainfed rice based cropping system of Chhattisgarh. Significantly lowest weed density, biomass and weed growth rate across all the growth stages under ZT direct drilling of seeds and fertilizers at 2nd days after harvesting (DAH) of rice as compare to other tillage practices. Among the Rabi crops, significantly lowest weed density, biomass and weed growth rate at all the growth stages except 30 DAS were observed with safflower crop. The combination of ZT direct drilling of seeds and fertilizers at 2nd DAH of rice and safflower can be used for better management of weeds   in rainfed rice based cropping system.

Abstract:

To study the floristic composition of weeds in wheat, 292 fields were surveyed in fourteen wheat growing districts of Haryana state during January–March 2012 and 2013. In all, 21 weed species (4 grassy and 17 broad-leaf) were found to infest wheat fields in Haryana. Grassy weed Phalaris minor was most dominant weed with IVI values of 43.2-97.7 in all the surveyed districts except Bhiwani, Mahendragarh and Rewari. Another grassy weed, Avena ludoviciana showed its presence with a RD of 0.5-21.7%  and IVI values of 1.5-43.4%  in south-western districts of Haryana. Grassy weeds of moist soils Polypogon monspliensis and Poa annua showed their presence only in north-eastern districts. Chenopodium album and Chenopodium murale, Trigonella polycerata, Melilotus indica, Rumex spinosus, Fumaria parviflora and Asphodelus tenuifolius were dominating broad-leaf weeds in south-western districts. Robust dicotyledonous weed Malva parviflora, adherent to heavy textured soils and zero till planted wheat, was mainly confined in Ambala, Karnal, Kurukshetra, Rohtak, Sonepat and Fardiabad districts. Convolvulus arvensis- a broad-leaf climber in all districts except Ambala and Karnal.

Abstract:

Rigid ryegrass (Lolium rigidum Gaud.) is a weed that caused significant losses in yields. The results showed that the density of ryegrass varied depending with the climatic regions and increased with increasing of rain. However, the density of this weed increased to the lower semi-arid to the sub-humid climate regions. Maximum infestation (657 plants/m²) of ryegrass was recorded in sub-humid against 9 plants/m² in the lower semi-arid climatic regions. Study of the correlation showed that the yield losses were highly correlated with density (r = 0.92847 and p=0.0001) with an exponential equation y = 109,56 e-0,001x. The results of the field trials showed that pre-mix mesosulfuron-methyl 7.5 g/ha + iodosulfuron-methyl-sodium 7.5 g/ha, pyroxsulam 23.3 g/ha and fenoxaprop-p-ethyl 64 g/ha + iodosulfuron-methyl-sodium 8 g/ha and chlortoluron 2400 g/ha controlled ryegrass effectively. At some locations, herbicides ACCase inhibitors (pinoxaden at 45 g/ha, diclofop-méthyl at 625 g/ha + fénoxapropo-p-ethyl at 50 g/ha and tralkoxydim at 320 g/ha) and ALS inhibitors (sulfosulfuron75% at 26.6 g/ha and flucarbazone sodium 70% at 43 g/ha) showed poor efficacy which may be due to the development of resistance in rigid ryegrass in many locations of Tunisia.

Abstract:

A laboratory experiment was conducted to study the effect of rice straw on the germination and seedling growth of four major weed species of wheat viz. Phalaris minor, Vicia sativa, Medicago denticulata and Lathyrus aphaca. Straw of three rice genotypes, Pant Dhan 16, UPR 2962-6-2-1 and UPR 2992-17-3-1, was added to petri dishes at two different doses (1g and 2g) on which weed seeds were allowed to germinate. It was observed that germination and seedling growth of all the four weed species was adversely affected by rice straw. Straw of the rice genotype UPR 2962-6-2-1 had maximum inhibitory effect and among the weed species Phalaris minor and Medicago denticulata were more sensitive to rice straw. Analysis of phenolics content of rice straw revealed maximum phenolics in the genotype UPR 2962- 6-2-1.  This shows the potential of rice straw incorporation in soil for weed management.

Abstract:

Zero tillage sowing of maize with residue mulching was found a viable alternatives method of crop establishment as compared to conventional raised bed sowing without residue. Thus, zero tillage sowing of maize with residue mulching resulted in lower weed infestation, higher productivity and economics returns. Atrazine 750 g/ha (as pre-emergence) fb 1 HW was effective in controlling weeds in maize crop.

Abstract:

The dominant broad-leaf weeds in the experiment field were Ageratum conyzoides, Amarantus viridis,Chromalaena odorata,Commelina bengalensis, Phyllanthus niruri and Mimosa spinosa. Cyperus rotundus and Cyperus iria were dominant among sedges. Among grassy weeds, Cynadon dactylon,Digitaria sanguinalis, Eleusine indica, Echinochloa colona were most dominant in blackgram. Hand weeding at 25 and 45 DAS gave maximum decrease in weed density, dry weight of weeds and recorded the highest growth and yield of blackgram; followed by application of pendimethalin 0.75 kg/ha fb 1 hand weeding at 25 DAS. Among the fertilizer doses, application of 40 kg/ha P2O5 + 40 kg/ha K2O recorded the highest seed and stover yields.

Abstract:

An experiment was done to see the allelopathic effect of Parthenium hysterophorus on the seed germination and seedling growth of maize (Zea mays) in laboratory conditions. The results showed that seed germination was negatively affected by the aqueous stem extract of Parthenium in different concentrations (15, 25, 50, 75 and 100%) when compared to control condition. Seed germination in control was 100% whereas this value was 3.33% in 100% of stem extract. Stem extract of P. hysterophorus on shoot length was more affected than the root length. T-test values for root length between control and 50, 75 and 100% were positively and significantly different at p<0.001; and for shoot length these values for different treatments were significantly different at p<0.001.

Abstract:

A common feature of pathogenic fungi to cause disease in plant is the necessity to pass through the plant cell wall, an important barrier against pathogen attack. To this end, fungi possess a diverse array of secreted enzymes to depolymerize the main structural polysaccharide components of the plant cell wall, i.e. cellulose, lignin and pectin. In the present investigation, six pathogenic fungal species such as Alternaria sp. PMK1, Alternaria sp. PMK2, Alternaria macrospora MKP1, Alternaria macrospora MKP2, Alternaria macrospora MKP3 and Alternaria macrospora MKP4 were isolated from diseased leaves of Parthenium plant and found to be pathogenic to this weed. Isolated fungi were examined for the presence of cellulolytic, pectinolytic, amylolytic and ligninolytic activity. Presence of enzymatic activities of these fungal indicating the importance of the cell wall degrading enzymes in pathogenicity against Parthenium weed.
