Evaluation of spiromesifen 240 SC against chilli mite Polyphagotarsonemus latus (Banks)

Field trails were conducted in farmers' holdings to evaluate the efficacy of spiromesifen 240 SC against chilli mite. In first field trial, spiromesifen @ 72,96 and 120 g a.i./ha recorded 83.8, 86.6 and 91.7 % mean reduction of chilli mite population, respectively whereas, in the second trial, it was 82.0, 88.0 and 92.3 %, respectively. Spiromesifen 240 SC showed better efficacy than dicofol 18.5 EC. Spiromesifen @ 120 g.a.i./ha was superior in the control of chilli mite. But the lower dose of spiromesifen, 72 g.a.i./ha was economically viable, if applied at early stage of mite infestation. Spiromesifen was found to have long lasting efficacy on chilli and at 120 g.a.i./ha reduced the leaf curl damamge from 41.8 to 12.5 %. Application of spiromesifen at 240 SC did not produce phytotoxicity.
