Abstract :
Recently incidence of Tetranychus urticae is a widespread issue in grape orchards in India. The possibility of a pesticide induced resurgence of mites was explored by applying field recommended doses of commonly used pesticides. The field trial revealed no resurgence with respect to dicofol, abamectin, spiromecifen, dichlorovos + fish oil resin soap, and dinocap usage consecutively. Sulphur induced heavy resurgence (16.55%) with resurgence ratio of
1.05, followed by thiamethoxam (8.89%), acetamiprid (6.97%), imidacloprid (6.15%) and buprofezin (5.46%) with resurgence ratios of 0.81, 0.89, 0.87, and 0.88 respectively.
