摘要
为探寻防治梨小食心虫的最佳药剂及其配比,开展梨小食心虫药剂防治试验。结果表明:成虫高峰期过后2～3d,分别喷施25%灭幼脲+杀灭菊酯1500倍液,或除虫脲2500倍液,均能有效控制梨小食心虫的发生及危害。
Chemical control experiments of G. molesta Busck were conducted to seek the best reagent and its ratio. Results indicated that spraying 25% Chlorbenzuron at 1 500 times, killing polyester at 1 500 times or diflubenzuron at 2 500 times, respectively, can control the occurrence and harm of G. molesta Busck during 4 -6 days after adult worm peak period.
