ABSTRACT
A field trial was conducted to test the bio-efficacy of five commercial acaricidal formulationsviz., azocyclotine 25% WP (Gallop), fenpyroximate 5% SC (Unique-M), diafenthiuron 500 SC (Trophy), hexythiazon 10% WP (Nissorun) and abamectin 1.8% EC (Commando) against brinjal mites, Tetranychus urticae, on brinjal crop under field conditions. Brinjal vegetable was raised under standard agronomic practices. Field recommended dose of these acaricides were used knapsack sprayer. Results showed a significant mite reductionby allacaricides as compared to control. Among the tested acaricides, hexythiazon 10% WP (Nissorun) gave the highest reduction of mites (i.e., 41.42, 55.56 and 37.90%) after 3, 5, and 7 days of first spray, respectively. Similarly, after second spray, hexythiazon 10% WP (Nissorun) again gave maximum reduction (i.e., 41.65, 39.33 and 16.40%) of T. urticae at 3, 5 and 7 days, respectively.
