Abstract
The field experiment was replicated thrice in randomised complete block design at Main Agricutural Research Station, Dharwad during kharif 2018 to study the bio-effiacy and phyto-toxicity of post-emergence herbicides tank mixtures on soybean (Glycine max L. Merrill). Application of Imazethapyr 75 g ha-1 + Quizalofop-p-ethyl 37.50 g ha-1 (75% RD) recorded significantly lower weed density (6.67 and 8.67 m-2 at 40 and 60 DAS, respectively), total weed dry weight (1.90 and 2.73 g m-2 at 40 and 60 DAS, respectively), and weed index (11.98%) with significantly higher weed control efficiency (77.75 and 85.79% at 40 and 60 DAS, respectively) seed yield and net returns (2,554 kg ha-1, ₹ 59,111 ha-1, respectively) over Imazethapyr alone. It was at par with RWMP (2,652 kg ha-1, ₹ 62,111 ha-1, respectively) and Imazethapyr 75 g ha-1 + Propaquizafop ethyl 75 g ha-1 (2,356 kg ha-1, ₹ 50,791 ha-1, respectively). There was.broad spectrum weed control through herbicide tank mixtures compared to Imazethapyr alone. Phytotoxicity was not observed due to tank mixtures of herbicides.
