Evaluation of Cyantraniliprole for Thrips and Red Spider Mite Management in Table Grapes

Laboratory bioassay and field experiments were conducted to evaluate the effectiveness of cyantraniliprole at different doses in comparison with recommended insecticides against thrips, Scirtothrips dorsalis and Rhipiphorothrips cruentatus and red spider mite, Tetranychus urticae in table grapes. In laboratory bioassays, cyantraniliprole @ 0.7 ml L⁻¹ was found to cause highest mortality of thrips and mites and was at par with standard checks. The mortality of thrips and mites was higher at 72 h as compared to 24 and 48 h after exposure. In field experiments, cyantraniliprole @ 70 g a.i. ha⁻¹ was most effective and was at par with higher dose of 80 g a.i. ha⁻¹ and standard checks of spinosad and thiamethoxam for thrips and fenpyroximate for mites during two fruiting season trials. None of the tested doses of the cyantraniliprole were phytotoxic. In a wide area field study also, cyantraniliprole @ 70 g a.i. ha⁻¹ proved to be effective in reducing thrips population in comparison with control.
