Abstract: A field trial was conducted during Rabi season of 2013-14 at the RRS, New Alluvial Zone, Chakdaha, BCKV, West Bengal to study the bio-efficacy and phytotoxicity of 2,4-D Ethyl Ester 80% EC in wheat. The experiment comprising of eight treatments and three replications was laid out in a Randomized Block Design. Applications of 2,4-D EE 80% EC @ 0.90 kg a.i.ha-1and 0.675 kg a.i. ha-1 have resulted in significant effective weed control in wheat along with simultaneous enhancement of grain yield. The said treatments were statistically superior to two round of hand weeding and other market available formulation i.e. 2,4-D EE 38% EC. Even up to 0.9 kg a.i.ha-1 of 2,4-D EE 80% EC application, there was found no phytotoxicity in wheat. So, this treatment can be a good option for managing weed in wheat under medium land condition of sub-humid, sub-tropical condition of West Bengal.
