Abstract:The field trials of 35% Rynaxypyr water dispe rsible granules were conducted from 2006 to 2007. The result show ed that the insecticide was suitable for controlling Carposina niponensisi Walsingham and Lithocolletis ringoniella Mats. Its control effect with the dosage of 35~ 50 mg / kg fluctuated from 83% to 100% after 5 days of spraying, and more than 77% after 35 days, but not as good as 35% Betacyperme thrin (EC). When the dosage was set 10~ 20 mg /kg to control Lithocolletis ringoniella, the control effect was 58% ~ 100% a fter 5 ~ 15 days of spraying, which was better than that of 25% diflubenzuron suspension with the concentration of 125 mg /kg.
