水稻中后期是多种害虫并发的时期,也是药剂进行总体防治的关键时期。为此,我们经过反复试验研究,开发了一种新型稻田主要害虫总体防治的理想药剂一单·吡啉。在二化螟、三化螟、稻飞虱低龄若虫高峰期或螟虫卵孵高峰期,每666.7m~2用单·吡啉100g 对水常规喷雾,适期用药一次,对稻飞虱、纵卷叶螟、二化螟、三化螟的防效均达95%左右,显著优于目前推广的药剂,是当前水稻害虫总体防治的首选药剂。
In the late rice is a period of multiple pests concurrent, but also a key period for the overall prevention and treatment of pesticides. To this end, after repeated trial and study, we have developed a new type of monoclopirox, the ideal drug for the prevention and control of major pests in paddy fields. In the stem borer, the yellow rice borer, planthoppers young nymphs peak or stem borer incubation peak, every 666.7m ~ 2 single with 100g of pyrrhotic water spray, the appropriate medication once, planthoppers, Rice leaf roller, striped stem borer, Borer on the control effect of up to 95%, significantly better than the current promotion of the agent, is the first choice for the overall prevention and treatment of rice pests.
