摘要
吡虫啉对茶树小绿叶蝉类有特效。在若虫高峰期,每公顷用10%可湿性粉剂525~750克,对水1500公斤喷雾,药后3天防效93.7%以上,15天内防效维持在92.9%以上,持效期长达40天。具速效和持效期长的特点。
The result of field trials showed that 100/0 imidacloprid WP at 525 ̄ 750glha diluted with 1500kg water sprayed during the peak stage of nymphs gave good control against E. flavescens and E. pirisuga. The control effect was over 93. 7/00 at 3rd day after treatment and over 92. 9/00 during 15 days after treatment,and the persistant was sustained for 40 days.
