【摘要】 采用静电喷雾机进行了静电喷雾和非静电喷雾2%噻虫啉微胶囊悬浮剂和3%高渗苯氧威乳油防治马尾松毛虫Dendrolimus punctatus(Walker)、杨小舟蛾Micromelalopha troglodyta Graeser及杨扇舟蛾Clostera anachoreta(Fabricius)幼虫对比试验。结果表明:在同一药剂浓度下,林间防效静电喷雾明显优于常规喷雾;2%噻虫啉微胶囊悬浮剂4 000倍液和3%高渗苯氧威乳油3 000倍液可作为静电喷雾防治马尾松毛虫2～3龄幼虫和杨小舟蛾及杨扇舟蛾2～4龄幼虫的推荐使用浓度。更多还原

【Abstract】 Comparative experiments were made in the forest with electrostatic spraying and non-electrostatic spraying of Thiacloprid 2% CS and Fenoxycarb 3% EC against the larvae of Dendrolimus punctatus,Micromelalopha troglodyta and Clostera anachoreta.The results showed that the field control effect of electrostatic spraying was significantly better than that of non-electrostatic spraying at the same concentration;Thiacloprid 2% CS 4 000 times and Fenoxycarb 3% EC 3 000 times was proposed as the recommended concentration for electrostatic spraying against Dendrolimus punctatus in the 2nd or 3rd instars or Micromelalopha troglodyta and Clostera anachoreta larvae in the 2nd-4th instars.更多还原
