The losses in rice crop yield caused by weeds range between 9-51% in varying agro climatic conditions. Butachlor herbicidal application was observed very common amongst farmers during participatory rural appraisal survey (PRA) of KVK adopted villages in Gwalior district of Madhya Pradesh. Butachlor was reported less effective by the farmers during the participatory survey of the villages. Therefore fifteen front live demonstrations on chemical weed control practices with newer broad spectrum herbicides were laid down in 05 villages of Bhitarwar and Dabra blocks of district Gwalior in transplanted rice during three consecutive kharif seasons of the year 2012-13 to 2014-15 to demonstrate the performance and profitability of new herbicides viz. chloromuron -ethyl + metsulfuron-methyl and bispyribac sodium at 0.020 and 0.025 kg/ha, respectively. The farmers’ fields were observed infested with mixed flora of grasses, sedges and broad leaf weeds. The herbicides used for demonstrations were found to be very effective in controlling weeds and thereby increasing grain yield of rice by 12-17.5 percent over farmers practice and gave higher weed control efficiency of 75.25 to 93.23 percent over the farmers practice. The herbicidal weed control demonstration also proved economically superior over F.P. by recording higher net income ranging from 1,06,255 to 1,20,345 per ha and B:C ratio from 4.70-6.08 during three years of study.
