Post emergence application of 2,4-Dichlorophenoxyacetic acid (2,4-D) as a herbicide even at low concentrations showed an effective control on three weeds (slender amaranth, goosefoot and prickly burweed) associated with maize growth. 2,4-D was applied at 0.0, 125, 250, 500 and 1000 ppm. 500 ppm 2,4-D treatment significantly decreased numbers and fresh weights of the three weeds by 50% approximately. At 1000 ppm 2,4-D, there were sever reductions in weeds numbers, fresh weights and photosynthetic pigments contents of the three weeds. Fresh weights and photosynthetic pigments contents of maize were favored significantly after application of 2,4-D on its associated weeds at all tested rates.
