An experiment was conducted to evaluate the Bio-efficacy and Phyto-toxicity of Fenoxaprop 6% + Pyrazosulfuron Ethyl 1.5% + Pretilachlor 50% ME (ready-mix)against monocot weeds and dicot weeds in paddy at Krishi Vigyan Kendra, Sirsi of University of Agricultural Sciences, Dharwad during Kharif 2018 and Kharif 2019. This new ready-mix herbicide was tried at different concentrations (800,1000 and 1200 ml /ha) and compared with other herbicides viz.,Check I -Chlorimuron Ethyl 25% WP @ 24g/ ha., Check II-Fenoxaprop-p-ethyl 9.3% w/w EC @ 625 ml/ha., Check III- Pretilachlor 50% EC @ 1500 ml/ha and Check IV- Pyrazosulfuron ethyl 10% WP@ 150 g/ha. These herbicide treatments were compared with hand weeding, weed free and untreated control treatments. Fenoxaprop 6% + Pyrazosulfuron Ethyl 1.5% + Pretilachlor 50% ME (ready-mix)@ all the doses recorded lower weed dry weight as compare to rest of the treatments. Among chemical treatments, Fenoxaprop 6% + Pyrazosulfuron Ethyl 1.5% + Pretilachlor 50% ME (Readymix)@ 1200 ml/ha recorded the lowest weed dry weight followed by Fenoxaprop 6% + Pyrazosulfuron Ethyl 1.5% + Pretilachlor 50% ME (ready-mix) @ 1000 ml/ha.Weed Free check recorded highest grain yield followed by Fenoxaprop 6% + Pyrazosulfuron Ethyl 1.5% + Pretilachlor 50% ME (Readymix)at 1200 ml/ha& 1000 ml/ha during both the seasons. Novisual symptoms of injury or phytotoxicity of Fenoxaprop 6% + Pyrazosulfuron Ethyl 1.5% + Pretilachlor 50% ME (ready-mix) were observed in even higher concentration of 3000 ml/ha on transplanted Paddy.
