Abstract:

Application 2,4-D at three levels in 0.5, 1.0 and 2.0 kg/ha in wheat crop at 35 days after sowing persisted in soil up to 15, 45 and 75 days, respectively. The logarithmic plots of herbicide residues versus time obtained by fitting the regression equation indicated that disappearance of 2,4-D in soil followed a first order kinetics decay curve at all the levels of application with the half life period varying from 4.21-17.70 days. Residues of 2,4-D were found below detectable level (0.02 ppm) in wheat grain and wheat straw.
