摘要

An experiment was carried out to assess the bio-efficacy of bio-rational insecticide against seed borer, Trymalitis margarias Meyrick on sapota at FRS, NAU, Gandevi (Gujarat) under ICAR-AICRP on Fruits. The sequential application of profenofos 50 EC and indoxacarb 14.5 SC reduced the fruit damage up to 2.83% and was statistically similar with deltamethim 2.8 EC and (Bacillus thuhngiensis var. Kurstaki) which recorded 2.94% fruit damage as compared to control (8.52%). While, application of spinosad and chlorantraniliprole had minimum fruit damage up to 3.48 %. The application of deltamethrin and Bt exhibited minimum unmarketable fruits yield (0.65 t ha1) and analogous with profenofos and indoxacarb (0.66 t ha~(-1)) than control (1.45 t ha~(-1)). After that, application of spinosad and chlorantraniliprole recorded fruit damage up to 0.81 t ha~(-1). The annual average marketable fruits yield was found higher in application of profenofos and indoxacarb (17.931 ha~(-1)) and found similar with deltamethrin and Bt (17.711 ha~(-1)) than control (14.591 ha~(-1).The research findings advocated the sequential application of deltamethrin @ 1 mL L~(-1) and Bt @ 1 g L~(-1) at 15 days interval at marble stage of fruit (October onwards) as economical and improve the number of marketable fruits in sapota.
