Abstract

Pear psylla, (Psylla pyricola Foerster) is an important economic pest of pear in Kashmir. For the control of Pear psylla (Psylla pyricola, F.), a field experiment was carried out to evaluate the efficacy of various insecticides viz. dimethoate, imidacloprid, thiacloprid, chlorpyriphos and malathion. All the evaluated insecticides showed high efficacy against Pear psylla (Psylla pyricola F.). Among these thiacloprid 21.7 SC @ 0.4 ml/litre was most effective with the efficacy of 94.19 per cent followed by imidacloprid 17.8 SL @ 0.4 ml/litre, dimethoate 30 EC @ 1ml/litre, chlorpyriphos 25 EC @1 ml/litre and malathion 50 EC @ 1 ml/litre with 92.64, 90.21, 89.26 and 87.11 per cent respectively.
