摘要
选用3 种浓度的50 % 甲胺磷乳油和40% 氧化乐果乳油两种药剂, 采用干基注射和茎干涂布防治日本落叶松球蚜1 ～3 龄期间的侨蚜。结果表明: 干基注射的防治效果显著优于茎干涂布, 用50 % 甲胺磷乳油进行干基注射的防治效果显著优于40 % 氧化乐果的干基注射。
Two kinds of chemicals 50% methamidophos missible and 40% flolimat missible which are respective in different thickness are chosen to control the alienicolas of 1～3 years of the adelgids in Larix kaempferi by butt injection and stem coating.The result shows that the butt injection is remarkable, the control effect of the butt injection by 50% methamidophos missible is remarkably superior to that of the butt injection by 40% flolimat.
