中文摘要：2006~ 2007年, 对35%氯虫苯甲酰胺水分散粒剂进行田间药效试验。结果表明, 35% 氯虫苯甲酰胺水分散粒剂是防治苹果树桃小食心虫Carp osina n iponensisiW a lsingham 和金纹细蛾L ithocolletisringon iellaM ats的有效药剂。其有效成分为35 ~ 50 m g /kg 处理防治桃小食心虫, 药后5 d 的防效在83% ~ 100%之间, 药后35 d防效在77%以上, 整体防效不及对照药剂4. 5%高效氯氰菊酯乳油30 m g /kg处理; 10~ 20 mg / kg处理防治金纹细蛾, 药后5~ 15d防效在58% ~ 100%之间, 各期防效优于生产常用药剂25%灭幼脲悬浮剂125 m g /kg 处理。
英文摘要：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.
