山楂红蜘蛛是苹果的主要害虫之一,在我县发生普遍,危害较重.目前果树多为个体管理,药械不足,且树体高大,不易防治.如何应用简单易行,经济、安全、有效的方法进行防治,是生产上亟待解决的问题.为此,我们于1982年试用氧化乐果涂茎,取得了较好的效果.一、涂茎的优点1、增强药效,延长残效.利用氧化乐果涂茎,药液可以随树液的流动均均地输送到树体的各个部位,避免了树体高大喷药不均匀和树冠内膛、树冠顶部喷不到药液的现象,提高了杀虫效率.如用10%的氧化乐果涂药后三天调查,虫口密度减退89.4%,不施药的则是原虫口密度的
Hawthorn spider mite is one of the main apple pests, occurs in my county, more harmful to the current fruit trees are mostly individual management, lack of drugs, and the tree is tall, not easy to control .How to apply simple, economical, safe and effective Method of prevention and control, is the production of the problem to be solved.To this end, we tested the omeprazole stems in 1982, and achieved good results. First, the advantages of stems 1, enhance efficacy, extend the residual effect. Omethoate stems, liquid medicine can be flowed with the tree liquid evenly to all parts of the tree to avoid the tree tall spray uneven and crown crown, crown can not spray the liquid medicine phenomenon, improve Insecticidal efficiency.As with 10% of omethoate three days after the survey, the population density decreased 89.4%, without the application of protozoa oral density
