Grassy and broadleaf weeds are simultaneously growing in soybean (Glycine max L.) crop and there is a lack of herbicides to control all types of weeds in a soybean crop. Thus, a field experiment was conducted during rainy (kharif) seasons of 2017 and 2018 to evaluate efficacy of fomesafen + fluazifop-p-butyl mixture against weeds and consequent improvement in productivity of soybean. Bio-efficacy was evaluated with 10 weed control treatments comprising of 4-doses of fomesafen + fluazifop-p-butyl mixture (90+90, 110+110, 130+130 and 220+220 g/ha), alone application of imazethapyr (100 g/ha), market check – fomesafen + fluazifop-p-butyl (110 + 110 g/ha), combined application of imazethapyr + imazamox (35 + 35 g/ha) as early post-emergence, hand weeding twice at 15 and 30 DAS, weedfree and weedy-check, were laid-out in a randomized complete block design with three replications. Application of premix fluazifop-p-butyl + fomesafen (130+130 g/ha) as early-post-emergence resulted in lower density, dry weight of all individual weeds with 99.2% weed control efficiency (WCE) and higher value of yield parameters and yield (2.01 t/ha) of soybean which was statistically at par with weed-free plots (2.04 t/ha). The higher dose of fomesafen + fluazifop-p-butyl (220+220 g/ha) was found effective against weeds but caused phytotoxicity to soybean crop and reduced seed yield marginally (1.98 t/ha). The fomesafen residues up to 130 g/ha dose were found below the detectable limit in the soil with zero per cent persistence at harvest. However, the highest dose of fomesafen (220 g/ha) resulted in residues in soil (0.016 μg/g) with 4.44% persistence and half-life of 13 days. These results suggested that premix
fomesafen + fluazifop-p-butyl at 130+130 g/ha as early-post-emergence can be safe for the application in soybean crop.
