abstract
Dissipation behavior of deltamethrin 2.5% EC (12.5 and 25 g a.i./ha) when applied on chickpea (var. Jaki 1211) thrice at 7 days interval for controlling pod borer under field conditions during rabi 2015-16 at pod initiation stage was studied. Green pods from recommended dose of deltamethrin retained residues (0.059 mg/kg) upto 7 days whereas from double the recommended dose retained residues (0.082 mg/kg) upto 10 days after final spray and dissipated to below limit of quantitation of 0.05 mg/kg by 10^th and 15^thday with halflife of 1.123 and 1.135 days respectively. Mature pods and soil at harvest contained residues below limit of quantitation (0.05 mg/kg).
