开展“两查两定”,合理使用农药,并与其他防治措施有机地配合,是贯彻“预防为主,综合防治”的重要环节。随着群众性“两查两定”的开展,提出了在目前生产水平下,如何确定防治指标,以能在基本上不造成经济损失的前提下,尽量把农药的使用量降低的问题。为此,本所与吴兴、长兴、嘉善、海宁、安吉、德清等县病虫观测站协作,对粘虫、二代纵卷叶螟和褐稻虱的防治指标,作了初步探讨。
Carrying out the “two checks and two regulations”, rationally using pesticides and organically coordinating with other prevention and control measures are important links in implementing “prevention first and comprehensive prevention and control”. With the development of “two checks and two determinations” of masses, the paper put forward how to determine the prevention and control index under current production level so as to reduce the use of pesticides as much as possible under the premise of not causing economic losses. To this end, the Institute and Wuxing, Changxing, Jiashan, Haining, Anji, Deqing and other counties pest stations in collaboration, the armyworm, the second generation of leafroller and brown planthopper prevention and control indicators, made a preliminary discussion.
