摘要
以50 g/L双丙环虫酯可分散液剂和10%虫螨腈悬浮剂为试验药剂,在2个小贯小绿叶蝉虫口峰期分别调查2种不同类型药剂的防治效果。结果表明,第1个虫口峰期,小贯小绿叶蝉虫口数多于第2个虫口峰期;药后1 d,两次试验中双丙环虫酯对小贯小绿叶蝉的防治效果均达90%以上,且第一次试验中双丙环虫酯的持效期长,在21 dpt仍有70%以上的防治效果。双丙环虫酯和虫螨腈处理对防治小贯小绿叶蝉均有较好效果。表明双丙环虫酯可用于高效防治茶园小贯小绿叶蝉。
Using 50 g/L afidopyropen and 10%chlorfenapyr as experimental pesticides,control effects of two different types of pesticides were investigated at two peak stages of tea green leafhoppers.The results showed that the number of tea green leafhoppers in the first peak stage was more than that of the second peak stage.At 1 dpt(days post treatment),the control effect of afidopyropen on tea green leafhoppers in the two experiments reached more than 90%.A persistent effect of afidopyropen in the first experiment was found and above 70%in control effect at 21 dpt was observed.Afidopyropen and chlorfenapyr both had good effects on the control of tea green leafhoppers.Thus,the results of this experiment indicated that 50 g/L afidopyropen could be used for the efficient control of tea green leafhoppers.
