Three insecticides viz. triazophos 40 EC, ethion 50 EC and endosulfan 35 EC alongwith standard insecticide dimethoate 30 EC were evaluated as foliar sprays against bean thrips, Megalurothrips distalis in mungbean (Vigna radiate) variety SML 668 during summer 2002, 2004 and 2005 at Punjab Agricultural University, Ludhiana. All the insecticides were found effective in reducing the incidence of bean thrips and they significantly increased the yield during these years. Triazophos 40 EC at 1.5 L/ha was the most potent treatment in reducing the damage, resulting in significantly higher mean yield (1393 kg/ha) as compared to control (1162 kg/ha) during the three years, followed by endosulfan 35 EC at 2.25 L/ha and ethion 50 EC at 2.0 l/ha (1360 kg/ha and 1334 kg/ha, respectively) which did not differ significantly between themselves. Triazophos 40 EC fetched the highest net returns (Rs.2717/ha) over control.
