Author(s): K Kavitha, V Anitha and M Aruna
Abstract: Persistence studies of cypermethrin and spiromesifen (50 and 125 g a.i./ha) when applied on okra (var. Arka Anamika) twice at 10 days interval for controlling shoot and fruit borer and leaf hopper under field conditions during rabi 2015-16 at fruit initiation stage was conducted. Okra fruits from recommended dose of cypermethrin and spiromesifen detected initial residues of 0.276 mg/kg and 2.401 mg/kg which persisted upto 7 days and 10 days after final spray and dissipated to below limit of quantitation of 0.05 mg/kg by 10th and 15thday with half life of 1.893 and 1.954 days respectively.
