Pre and post emergence herbicides for weed control in blackgram (Vigna mungo L.)

Abstract

A field experiment was conducted to study the pre and post emergence herbicides for weed control in blackgram at Agricultural Research Station, Anand Agricultural University, Derol, Gujarat, India during Kharif, 2016-17, 2017-18 and 2018-19. Eight treatments were studied in randomized block design with three replicatioins. Among the different weed management practices, post-emergence (20 - 25 DAS) application of propaquizalafop 10% EC 75 g a.i./ha fb IC + HW at 30 DAS or quizalofop-ethyl 5% EC 50 g a.i./ha fb IC + HW at 30 DAS or fenoxaprop-p-ethyl 9% EC 67.5 g a.i./ha fb IC + HW at 30 DAS most efficient in reducing weed density, weed dry weight, weed index as well as higher weed control efficiency, seed yield, haulm yield, net return and BC ratio of blackgram.
