Abstract
The bio-efficacy of clodinafop-p-propargyl 60 g/ha was better against Avena ludoviciana Dur. and Pharalis minor Retz. to that of sulfosulfuron 25 g/ha, penoxsulam + cyhalofop 105 g/ha, penoxsulam + cyhalofop 150 g/ha and carfentrazone 25 g/ha but it was poor against broad leaved weeds. However, the mesosulfuron-methyl + iodosulfuron-methyl sodium 12 g/ha, sulfosulfuron + metsulfuron-methyl 40 g/ha and combined application of clodinafop-p-propargyl + 2,4-D (60+500) g/ha gave effective control of grassy and broad leaved weeds. Use of pinoxaden 60 g/ha or clodinafop 60 g/ha a brought about a reduction in infestation of grassy weeds. Presently, some new herbicide ready mix combination of mesosulfuron-methyl + iodosulfuron-methyl sodium 12 g/ha, sulfosulfuron + metsulfuron-methyl 40 g/ha and tank mixture herbicides clodinafop + 2,4-D (60+500) g/ha appeared to be more profitable and efficient over other treatments.
