扑虱灵是选择性昆虫生长调节剂类型的新型杀虫剂,它具有抑制昆虫几丁质合成和干扰新陈代谢的作用,从而使若虫在蜕皮时死亡。1987～1988年我们在江汉稻区进行了两年的试验示范;1989年扩大至江汉稻区15个县(市)的4.5万亩大面积上示范推广。结果表明该药剂对稻飞虱具有高效、稳效,持效期长,对天敌安全,对不良环境有较强适应能力的特点,明显优于当前防治稻飞虱的常规农药,是防治稻飞虱的一种理想药剂。 一、扑虱灵防治稻飞虱的效果 1、防治效果好且稳定,持效期长 江汉平原混栽稻区,在田间稻飞虱2～3
Pupleurine is a new insecticide of selective insect growth regulator type, which inhibits insect chitin synthesis and disrupts metabolism, causing nymphs to die during molting. From 1987 to 1988, we conducted a pilot demonstration in Jianghan Rice Area for two years; in 1989 we expanded our demonstration to a large area of 45,000 mu in 15 counties (cities) in the Jianghan Rice Area. The results showed that the pesticide had the characteristics of high efficiency, stability, long duration, strong safety for natural enemies and strong adaptability to adverse environment. It was obviously better than the current pesticides for planthoppers control, An ideal medication for lice. First, the effect of planthoppers against planthopper 1, control effect is good and stable, the persistence period Yangtze River plain mixed rice area, in the field of planthoppers 2 to 3
