假眼小绿叶蝉是我国茶园重要害虫之一,为了寻找有效、安全的防治药剂,在浙江遂昌开展了15%茚虫威EC等5种新农药田间防治试验。结果表明:15%茚虫威EC50ml(a.i)/hm2(下同)、24%虫螨腈SC108ml、22%氯氟氰菊酯·噻虫嗪ZC66ml药后1—21d的防治效果在80%~90%之间,与10%吡虫啉WP90g的90%左右相比差异不显著,表明其速效性与持效性均较好;24%氰氟虫腙SC216ml药后1—14d的防效为28.95%~70.62%,极显著低于吡虫啉;25%吡蚜酮WP150g均显著低于吡虫啉。5种药剂对茶树及其他生物未见不良影响。生产上可将15%茚虫威EC、22%氯氟氰菊酯·噻虫嗪ZC、24%虫螨腈SC作为该区防治假眼小绿叶蝉的轮换药剂,逐渐替代10%吡虫啉WP。

Empoasca vitis is one of important pests in tea fields and constantly causes badly damage to tea leaves. Presently, chemical agents are often adopted to control this pest. In order to find new pest control chemicals featured with safety and efficiency, field trial of five kinds of new insecticides on controlling Empoasca vitis was investigated in Suichang county, Zhejiang province . The results showed that during the period of 1 to 21 days after sparying insecticides, the control efficiency of 15% Indoxacarb EC ,24% Chlorfenapyr SC and 22% Cyhalothrin ~ Thiamethoxam ZC were 80 - 90% at a dose of 50,108 and 66 ( ml/hm2 ) respectively. There was no significant difference ( P 〈 0.01 ) compared with the treatment by 10% imidacloprid WP at a dose of 90g/ha. It indicated that the 3 new insecticides had a good performance. The trial also showed that 25 % pymetrozineWP had a low eontroi efficiency at a dose of 150g/ha, which is significant lower than that of 10% imidacloprid WP at a dose of 90g/ha. It is concluded that insecticides as 15% Indoxacarb EC, 22% Cyhalothrin ~ Thiamethoxam ZC, 24% Chlorfenapyr SC can be used as substitute insecticides to control Empoasca vitis in this region.
