不同喷雾方式防治马尾松毛虫林间试验

Field Experiment of Different Spray Methods Against Dendrolimus punctatus

林间用静电和非静电喷雾3%噻虫啉微胶囊悬浮剂进行防治马尾松毛虫试验。结果表明,3%噻虫啉微胶囊悬浮剂相同浓度,用静电喷雾显著高于非静电喷雾杀灭效果。试验筛选出静电喷雾3%噻虫啉微胶囊悬浮剂4000倍药液浓度防治2-3龄幼虫马尾松毛虫较为适宜。

To prevent and control of Dendrolimus punctatus by spraying 3 % thiaeloprid microcapsule suspending agent with electrostatic and non electrostatic in forest field. The results showed that 3 % of the same concentration of the suspension of the capsule of the same concentration, the electrostatic spray was significantly higher than the non electrostatic spray killing effect. The experiment was to screen the 3 % times of the electrostatic spray and times the concentration of the suspension of 4000 times of the drug in the treatment of the larvae of the pine caterpillar.
