The plot experiment results showed that the control efficiency of Lambda-cyhalothrin Chlorantraniliprole 150 g/L ZC against Heliothis armigera of tomato was obviously higher than that of the two standard insecticides. In the year 2008 and 2009, the control efficiency of 1, 3, 7, 14, 21 days after spraying reached to 76.03%, 86.99%, 96.05%, 92.11%, 86.67% and 73.45%, 83.68%, 92.12%, 88.87%, 83.09% respectively, and did no hazard tomato. According to the tests and actual production, lambda-cyhalothrin chlorantraniliprole 150 g/L ZC spray at the dose of 22.50～33.75 g(a.i)/hm2 were recommended.%经过2年田间试验,研究150 g/L氯虫苯甲酰胺·高效氯氟氰菊酯微囊悬浮剂防治番茄棉铃虫(Heliothis armigera)的效果.结果表明,150 g/L氯虫苯甲酰胺·高效氯氟氰菊酯微囊悬浮剂45.00 g(a.i)/hm2(300 mL/hm2)防治棉铃虫效果最佳,2008年药后1、3、7、14、21d的防治效果分别为76.03％、86.99％、96.05％、92.11％、86.67％,2009年药后1、3、7、14、21 d的防治效果分别为73.45％、83.68％、92.12％、88.87％、83.09％,均明显高于对照药剂25g/L功夫水乳剂和250g/L氯虫苯甲酰胺悬浮剂,防治效果好,且对番茄生长无药害.结合试验和生产实际考虑,推荐150g/L氯虫苯甲酰胺·高效氯氟氰菊酯微囊悬浮剂防治番茄棉铃虫田间使用剂量为22.50～33.75g (a.i)/hm2,对水喷雾.
