Abstract
A field experiment was conducted at ICAR-KVK, Kalaburgi, during Kharif seasons of 2018-19 and 2019-20 to adjudge the efficacy of pre and post emergence herbicides against diverse weed flora in pigeonpea ecosystem. The experiment was laid out in RCBD with 11 treatments comprising of different pre-emergent herbicides viz., Pendimethalin, Pendimethalin 30 EC + Imazethapyr 2 EC and post-emergence premix product herbicides such as Imazamox 35 WG + Imazethapyr 35 WG, Propaquizafop 2.5% + Imazethapyr 3.75%w/w ME and their different dosages with cultural methods were compared with weed free check and weedy check treatments. Among the different pre and post emeregent herbicides tested against different weed flora, post emergent application of Propaquizafop 2.5% + Imazethapyr 3.75% w/w ME @ 2000 ml ha-1 at 20-25 days recorded significantly lower weed density, weed dry weight, highest weed control efficiency (91.36%) and lowest weed index (8.78%) and higher grain yield (1209 kg ha-1 ), net returns (` 43,036 ha-1) and benefit cost ratio (2.35) followed by Propaquizafop 2.5% + Imazethapyr 3.75% w/w ME @ 1500 ml ha-1 at 20-25 DAS, Imazamox 35 WG + Imazethapyr 35 WG at 100 g ha-1 at 20-25 DAS and HW at 20 and IC 40 and 60 DAS.
