Efficacy of Some Insecticides Against Thrips and Yellow Mites in Chilli

Abstract

Efficacy of some insecticides new chemistry insecticides was evaluated against chilli thrips Scirtothrips dorsalis and yellow mite Polyphagotarsonemus latus, during kharif, 2019 and green and red chilli samples were subjected to residue analysis to evaluate the persistence of sprayed pesticides. Spinetoram 11.7SC at 60 g a.i./ ha was observed to be superior in managing chilli thrips with a mean reduction of 93.35% with least thrips population (0.53/ top 3 leaves) followed by cyantraniliprole 10.26OD at 60 g a.i./ ha and spirotetramat 15.31OD with 90.78 and 85.44 mean % reduction, respectively. Management of yellow mites was effective in plots treated with abamectin 1.9EC at 7 g a.i./ha of 85.73 mean per cent reduction followed by chlorfenapyr 10SC at 100 g a.i./ ha (83.48%) and emamectin benzoate 5SG at 10 g a.i./ ha (76.64%). Lambda-cyhalothrin and chlorantraniliprole residues were detected in green and red chilli among the sprayed pesticides.
