摘要
应用树大夫 (树虫一针净 )、齐螨素防治紫薇囊毡蚧效果均在 90 %以上 ,蚜虱净防效不理想。树大夫防治光肩星天牛效果在 70 %以上。树大夫树干注药 ,残效期长 ,无污染 ,对天敌安全 ,果实无残留 。
Shudaifu and Abamectin were used against Eriococcus lagerostroemiae. The result showed they can kill over 90% of the pest,but the control effect of imidacloprid was not satisfactory.The control effect of Shudaifu against Apriona swainsoni was above 70%.Trunk inoculation of Shudaifu was long lasting,pollution free,safe to natural enemies and no pesticide residue in fruits. It could be popularized in the production.
