Weeds are serious biological constraints in the rice production system. A survey was conducted using a structured questionnaire in two major rice-growing districts of Chhattisgarh Plains. There were 136 respondents. The objectives of the survey were to assess farmers’ knowledge of current weed management technologies, farmers’ adoption of available technologies and identify challenges faced by farmers to help in order to develop need-based sustainable weed management strategies. The majority of the farmers (68.4%) have reported using their seeds for sowing with 58% of the farmers cleaning the seeds before sowing. A seed rate of 120 kg/ha was being used by 55% of the rice growers. The majority of the respondents (58.8%) were aware of chemical weed management in crops. However, 89.7% of farmers were reportedly unaware of the correct dosage rate (45.6%) and correct application time (44.1%) of post-emergence herbicides. Regarding herbicide application timing, 55% of respondents applied at the 6-8 leaf stage of the weeds; 25% at the 5-6 leaf stage, and 20% were unaware of the time of herbicide application. Likewise, 88.2% of respondents spray the herbicide in a swinging pattern. This study highlighted the urgent need for policy intervention to improve the herbicide application technological knowledge level of rice farmers to improve input use efficiency and produce rice sustainably.
