“Application of 2,4-D EE 80% EC 0.90 kg a.i. ha-1and 2, 4-D EE 80% EC 0.675 kg a.i. ha-1 have resulted in effective weed control, and contributed in significantly high grain yield of wheat and no phytotoxicity through these said treatments which were statistically comparable to hand weeding twice.”
