 ABSTRACT

Pod fly, Melanagromyza obtusa Malloch is a serious pest of Pigeon pea. During the present investigation, ten insecticides were evaluated under field and laboratory conditions. Results of experiments showed that after 3 and 6 hr, Emamectin benzoate (0.001 %) and Dimethoate (0.03%), followed by Indoxacarb (0.004%), Dichlorvos (0.08%) and Fenvalerate (0.02%) recorded higher per cent of adult mortality and the NSKE (4 %) treated pods received the least number of eggs and was significantly superior over others. Significantly lower per cent seed damage was recorded for plots sprayed with Dimethoate 0.03%. The highest seed yield was obtained from plots treated with a combination of NSKE 5%-Emamectin benzoate 0.001%-Dichlorvos (1666.00 kg/ha) and Dichlorvos- Dimethoate 0.03%- cypermethrin 0.01% - Emamectin benzoate 0.001% (1583.00 kg/ha) over control. These results can substantially contribute to the development of IPM in Pigeon pea.
