Blackgram, Efficacy, New generation, Pre and post-emergence herbicides.Abstract
The field experiment was conducted during rabi, 2022-23 at Wetland Farm of S.V. Agricultural College, Tirupati, to evaluate theefficacy of new generation herbicides for weed management in blackgram with nine weed management practices in a randomized block design replicated thrice.Results revealed that among all the weed management practices at 60 DAS lower density (8.06 No.m-2) and biomass (6.26 g m-2)of total weeds coupled with higher weed control efficiency and weed control index(74.67 & 74.50 %) was recorded withpre-emergence application of diclosulam 20 g ha-1 + 1 HW at 15 DAS, which was followed by PoE application of fluazifop-p-butyl + fomesafen 222 g ha-1(69.32 & 69.28 %) and PoE application of sodium acifluorfen + clodinafop propargyl 245 g ha-1(68.46 & 68.62 %). Higher seed yield (971 kg ha-1) of blackgram was noticed with HW twice at 15 and 30 DAS, which was at par with PoE application of fluazifop-p-butyl + fomesafen 222 g ha-1(957 kg ha-1) and PoE application of sodium acifluorfen + clodinafop propargyl 245 g ha-1(910 kg ha-1).
