【摘要】 该项研究以大连金州区国营农场为苹果病虫无公害防治试验示范基地。研究结果表明,每666.7m2果园释放4～8万头赤眼蜂,果实被害率仅为7.6%～3.2%;套袋可使病虫果降为0,打药减少6次;防治二斑叶螨可选用海正灭虫灵和爱福丁,防治金纹细蛾可选用灭幼脲3号和杀虫丹,防治绣线菊蚜可选用吡虫啉,防治轮纹病可选用中生菌素(对天敌无害),防治腐烂病可选用灭腐王。更多还原

【Abstract】 State-operated Farm of Jinzhou District,Dalian was taken as the demon strative field for non-pollution control of apple diseases and pests in this stu dy.The results showed that the fruit infestation percentage was only7.6%～3.2%by releasing40～80thousands of oophagous Trichogrammae per666.7m 2 ;the fruit infestation percentage was decreased to0and saved6times pesticide application by bagging fruit.Abamectin and Everdin could be applied for the control of Tetranychus urticae,Dichlorbenzuron III and Monosultap for Asiatic apple leaf-miner(Lithocolletis ringoniella Matsumura),Imidacloprid for spiraea aphid(Aphis citricora van der Goot),Zhongshengmyctin for canker of fruit(Physalospora piricola Nose)and Miefuwang for canker of appl e(Valsa mali Miyabe et Yamada).更多还原
