Abstract:

Relative efficacy of different biorational insecticides against major insect pest on brinjal was evaluated in field condition at the Horticulture Farm of Agricultural College and Research Institute, Killikulam, Thoothakudi during Kharif from July to October. The results showed that the two applications of Buprofesin 25SC (0.8 ml/lit) was found significantly most effective, which caused maximum population reduction of sucking insect pest of brinjal leaf hopper, 78.78, aphid, 81.24, and whitefly, 80.86 per cent. It was followed by Emamectin benzoate 5 WG (0.4 g/lit) with 74.27, 71.73 and 70.65 and Spinosad 45 SC (0.5 ml/lit) 73.20, 66.09 and 63.54 per cent mean population reduction. Chlorpyriphos 20 EC (2.5 ml/lit) was found least effective against the pest of leaf hopper, aphid and whitefly with the per cent reduction of 31.25, 32.24 and 31.88% and it was followed by Novaluron (0.5 ml/lit) was found second least effective against the insect pest of leaf hopper, aphid and whitefly with the percentage reduction of 43.01, 39.32 and 39.77 per cent.
