Efficacy of Spirotetramat 150 OD against Two Spotted Spider Mite, Tetranychus urticae Koch on Brinjal, Solanum melongena L.

Field studies at two locations viz., Pullakoundanputhur and Vadivalenpalayam, Coimbatore, to assess the efficacy of spirotetramat 150 OD (60, 75 and 90 g a.i. ha⁻¹) in comparison with thiamethoxam 25 WG (25 g a.i.ha⁻¹) and dicofol 18.5 EC (250 g a.i. ha⁻¹) against two spotted spider mite, Tetranychus urticae Koch on brinjal revealed that foliar application of spirotetramat at 90 and 75 g a.i. ha⁻¹ was highly effective followed by spirotetramat at 60 g a.i. ha⁻¹ and dicofol 18.5 EC at 250 g a.i ha⁻¹. Consequently, maximum fruit yield of brinjal was obtained in these treatments.
