Abstract:
The experiment was conducted for two years during kharif season of 2014 and 2015 at Directorate of Research building, BCKV, Kalyani of West Bengal to find out the bio-efficacy and phytotoxicity of 2, 4-D ethyl hexyl ester 60% EC for weed control in non-crop area. Elusine indica, Cynodon dactylon, Imperata cylindrica, Cyperus rotundus, Cyperus iria, Ageratum conyzoides and Lantana camerawere the dominant weeds. The application of 2,4-D EHE 60% EC 1.296 kg a.i ha^-1 and 2,4-D EHE 60% EC 1.152 kg a.i ha^-1 has resulted in effective weed control recording the least weed density and weed dry weight and there by higher weed control efficiency after hand weeding treatment plot. The herbicide 2, 4-D EHE 60% EC tested at different doses was found safe to the non-crop area.
