Field Efficacy of Some Insecticides and Biopesticides for the Management of Shoot Gall Psylla, Apsylla cistellata Buck

Studies were conducted to study the field efficacy of insectides, botanicals and entomopathogenic fungi for the control of shoot gall psylla, Apsylla cistellata Buck and subsequently their effect on fruit set and fruit yield of mango. Maximum per cent embryo mortality and minimum number of galls/twig and nymphs/gall were recorded in monocrotophos followed by quinalphos whereas minimum per cent embryo mortality and maximum number of galls/twig and nymphs/gall were observed in nimbicidine, neem seed kernel extract, Baeauveria bassiana and control. Maximum fruited shoot, fruits harvested and fruit yield were recorded in monocrotophos and quinalphos whereas about zero fruit yield was recorded in nimbicidine, neem seed kernel extract, B. bassiana and control.
