Fate Of Pendimethalin Herbicide In Soil And Pea Plant (Pisum Sativum L.)

Author(s): Anjana Srivastava, Suchi Pandey, Shishir Tandon

The persistence and dissipation of pendimethalin herbicide at two fortification levels i.e. 1 and 2kg/ha in soil, leaves and pods of pea plant were performed. The degradation of pendimethalin in soil during 0 to 2 days was many folds higher than the later degradation which continued till 60 days for 1 kg/ha and upto 74 days for 2kg/ha. No detectable residue was found after 60 days and 74 days for both the rates of application. Dissipation followed first order kinetics which could be better accounted by a biphasic pattern.
