abstract
An experiment was conducted to test the efficacy of various pesticides against spider mite, Tetranychus urticae (Koch) infesting brinjal. Among all the pesticides the treatment fenazaquin 10 EC@0.01% was found superiority over rest of the treatments and registered lowest spider mite population (0.80 mites/leaf), however, the highest spider mite population was recorded in case of control (47.67 mites/leaf). The highest marketable yield of brinjal was obtained in the treatment fenazaquin 10 EC@0.01% (12.96 q/ha) and was statistically superior over the rest of the treatments. The lowest marketable yield was obtained in the case of Control (5.96 q/ha). Further, the higher BCR of 1:9.081 was recorded in the treatment fenazaquin 10 EC@0.01% (T₁) while, the lowest BCR was recorded in case of treatment neem Oil @0.15% (1:0.259) (T₆).
