杀虫脒可以用于防除对有机氯、有机磷产生抗性的害虫,杀虫效果好。且具有内吸性、残效期长等特点,因而近几年来,成为我县生产上用量最多的农药品种。1983年使用99吨,1984年达114吨。在使用实践中,我们感到有以下六点是要注意的。 一、注意防治对象。我县实践证明,杀虫脒是二化螟、三化螟、稻纵卷叶螟等害虫的特效药剂,正确使用,杀虫效果可达90~100%。用于防治棉叶螨,对成、若螨及卵的效果高达95%。但对大螟、蓟马、稻瘿蚊、叶蝉类等效果很差。杀虫脒对许多天敌,如食螨瓢虫、寄生蜂类伤害较小。

And has internal absorption, long residual period and other characteristics, so in recent years, become the largest county in the production of pesticides varieties. 99 tons in 1983 and 114 tons in 1984. In practice, we feel the following six points should be noted. First, pay attention to prevention and treatment of objects. Practice has proved that my county, chlordimeform Chilo suppressalis, yellow rice borer, rice leaf roller and other pests and effective agents, the correct use of insecticidal effect of up to 90 to 100%. For the prevention and treatment of cotton spider mites, into, if the effect of mites and eggs up to 95%. However, Sesamia inferens, thrips, rice gall midge, leafhoppers and other effects are poor. Chlordimeform on many natural enemies, such as food mites ladybug, parasitic wasps less damage.
