Abstract
A field experiment conducted during kharif, 2016 at Regional Agricultural Research Station, Lam, Guntur dist. Andhra Pradesh to know the time of application of insecticide and its economics for the management of podfly revealed that the insecticide dimethoate 30 EC @ 2 ml l-1 applied at 2, 3, 4 and 5 weeks after 50% flowering was found most effective in reducing pod and grain damage due to podfly with more yield. However, the same insecticide applied twice at 3 and 4 weeks after 50% flowering was most promising and can be recommended, as it registered more incremental cost benefit ratio (ICBR) of 17.77.
