Bio-efficacy of promising post-emergence herbicides alone and in combination against major weeds in soybean
Author(s): AU Andhale and DK Kathmale
Abstract: A field experiment was conducted during Kharif season of 2015 at Agriculture Research Station, Kasbe Digraj, Sangli, Mahatma Phule Agricultural University, Maharashtra, India. The dominant broad-leaved weeds in the field were Commelina benghalensis, Acalypha indica, Digera arvensis, Parthenium hysterophorus, Amaranthus viridis and Euphorbia geniculata. Grassy weeds were Echinochloa colonum, Brachiaria reptans, Dinebra arabica, Digitaria longiflora and Cynadon dactylon and Cyperus rotundus as sedge. Results revealed that, post-emergence application of Fluazifop-p-butyl + Fomesafen @ 300 g a.i. ha-1 recorded significantly lower weed density and total weed dry weight at 45 DAS. Higher weed control efficiency (86.36%) was recorded with post-emergence application Fluazifop-p-butyl + Fomesafen @ 300 g a.i. ha-1. Post-emergence application of Fluazifop-p-butyl + Fomesafen @ 300 g a.i. ha-1 recorded significantly higher seed yield (1776.00 kg ha-1) and which was at a par with application of Imazethapyr + Quizalofop-ethyl @ 175 g a.i. ha-1 as post-emergence and weed free check with highest B:C ratio.
