Bio-efficacy of new molecules of herbicides for weed management in soybean (Glycine max L. Merril)

Abstract

A field experiment was conducted to study the bio-efficacy of new molecules of herbicides for weed management in soybean during two consecutive rabi season of 2017 and 2018 at AICRP-Weed Management, B. A. College of Agriculture, Anand Agricultural University, Anand on loamy sand soil. IC fb HW at 20 and 40 DAS followed by imazethapyr 100 g/ha PoE fb IC+HW at 30 DAS, pendimethalin 750 g/ha PE fb IC+HW at 30 DAS, quizalofop-ethyl 50 g/ha PoE fb IC+HW at 30 DAS, pendimethalin + imazethapyr 960 g/ha PE (PM) fb HW at 30 DAS, clomazone 1000 g/ha PE fb IC+ HW at 30 DAS and diclosulam 25.2 g/ha PE fb IC+HW at 30 DAS recorded significantly lower density and dry weight of weeds and also recorded more than 94 per cent of weed control efficiency at harvest and also found superior in respect of recorded significantly higher growth, yield attributes and yield of soybean.
