Efficacy Of Cyantraniliprole 300 G/L OD Against Thrips (Scirtothrips Dorsalis) And Flea Beetle (Scelodonta Strigicollis) On Grapes

Abstract

Thrips, Scirtothrips dorsalis and flea beetle, Scelodonta strigicollis are the two important destructive pest prevailing in the grapes ecosystem in the terms of economic damage is concern. Field studies were conducted during two consecutive seasons of 2022 and 2023 in order to evaluate the field bio-efficacy of a new anthranilic diamide molecule Cyantraniliprole 300 g/L OD (45, 60, 75, 90 and 105 g a.i./ ha) along with Lambda- cyhalothrin 4.90 % CS (12.5 g a.i./ha) and Emamectin benzoate 5% SG (11 g a.i./ha) as standard checks against the thrips (Scirtothrips dorsalis) and flea beetle (Scelodonta strigicollis) in grapes. The two higher doses of Cyantraniliprole 300 g/L OD i.e. 90 and 70 g a.i./ha was found highly effective in managing the population of thrips and flea beetle during both the year compared to Lambda-cyhalothrin and Emamectin benzoate. The highest grapes yield was recorded in plots treated with Cyantraniliprole 300 g/L OD @ 90 g a.i./ha (19.45, 19.6136 t/ha respectively) and it was statistically on par with its lower dose of 70 g a.i./ha (19.3661, 19.52 t/ha respectively) during first and second field trials. Considering the bio-efficacy and yield, Cyantraniliprole 300 g/L OD @ 70 g a.i./ha is recommended for effective control of thrips and flea beetle pests in grapes ecosystem.
