悬铃木方翅网蝽飞机防治试验初报

The Preliminary Report on Using of Aircraft for Prevention Control of Corythucha Ciliate

运用空中拖拉机AT-504喷洒5%啶虫脒乳剂防治第3代悬铃木方翅网蝽,结果表明:飞机防治作业后,第1d虫口减退率为1%、第4d虫口减退率为1.48%、第10d虫口减退率为1.89%,防治效果不明显。分析讨论了影响飞防质量的几个关键因素,建议法桐方翅网蝽防控要分类施策,以人工防控为主,飞防为辅,采取地面喷冠、树干注药、农药灌根、烟雾机防治等综合防治技术。

In this paper, the experiment of Spraying 5% acetamiprid emulsion by using Air tractor AT-504 to prevent the third generation of corythucha ciliate were carried out. The results showed that, after aircraft control operation, the bug population decline rate of the first day, the fourth day and the tenth day were 1%, 1.48% and 1.89% respectively, of which the control effect was not obvious. Several key factors which affected the quality of aircraft control were also discussed, and classification of controlling corythucha ciliate was suggested, which based on artificial prevention, and supplemented aircraft control, meanwhile, ground spray crown, trunk injection, pesticides irrigating to root, smoke machine ontrol and so on were also put to use.
