摘要
介绍了维依戈杀虫剂SC对白菜鳞翅目害虫的生物防治效果评价结果。对菜蛾(Plutella xylostella l .)和白菜勺(Mamestra brassicae l .)的保护效果高达100%,用量分别为0.15和0.25 l/ha。使用杀虫剂Voliam Targo, SC (0.8 l/ha),可以将小白菜蛾的幼虫数量减少96.9%,白菜勺减少100%。结果表明,该药剂对害虫的生物杀灭效率达到100%。研究表明,所有杀虫剂对白菜蛾和白菜勺种群的影响相当持久,持续14-28天。
USE OF VAIEGO, SC IN CONTROL OF LEPIDOPTERA CABBAGE PESTS
Results of evaluation of biological efficiency of Vaiego insecticide, SC in control of lepidoptera cabbage pests are presented. A high, up to 100 % protective effect of the studied preparation against cabbage moth (Plutella xylostella L.) and cabbage scoop (Mamestra brassicae L.) was established in the consumption rates of 0,15 and 0,25 l/ha. The use of the insecticide Voliam Targo, SC (0,8 l/ha) made it possible to limit the number of caterpillars of cabbage moth by 96,9 %, cabbage scoop by 100 %. It was noted that the biological efficiency of Koragen, SC reached 100 % in relation to pests. A rather long-lasting effect was shown, for 14–28 days, on the populations of cabbage moth and cabbage scoop of all insecticides studied.
