Abstract

Endosulfan applied at flowering and pod formation stages by foliar spraying @ 330 and d70 0 g.i. ha−1 revealed half-lives of 4.2 and 4.7 d on foliage and 5.8 ana 5 d on pods for the two levels of treatment, respectively. The terminal residues at harvest on pigeonpea pods and pod covers (collectively) were 1.73 and 2.45 Ug g−1 for the recommended and the double doses, respecttvely. The corresponding values for grains were 0.43 and 0.79 μg g−1. Washing and cooking of the pods reduced the residues by 45–58 and about 74–87%, respectively. The safe waiting periods were found to be 1 and 5 d for the two levels of treatments, respectively.
