水稻中后期是多种害虫并发时期，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──单·吡啉。在稻飞虱二、三龄若虫高峰期或螟虫卵孵高峰期，每666．7m2用单·吡啉100g对水常现喷雾，适期用药1次，对稻飞虱、稻纵卷叶螟、二、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理想药剂。
Mid and late rice is a period of multiple pests concurrent period, but also a key period for the overall prevention and treatment of pesticides. To this end, after repeated trial and study we developed a new type of rice fields the main agent of the overall prevention and control of the ideal agent - monopylmorpholine. In the second and third instar nymphs of the planthopper or the peak period of the stem borer, every 666.7m2 was sprayed with water of 100g / The control effect of Borer, Borer and Sesamia inferens reached 95%, which was significantly better than that of the current ones. It is an ideal agent for the overall prevention and control of rice pests.
