稻纵卷叶螟是水稻主要害虫之一,自推广杀虫脒防治以来,收到显著效果.但由于杀虫脒残效期长,有残毒,使用次数及使用时间受到一定的限制,所以生产上急需寻找取代杀虫脒防治稻纵卷叶螟的新药剂.1979-1981年,我们对多种农药进行了筛选,发现甲胺磷对稻纵卷叶螟具有优异的杀虫效果.在此基础上,1982年对其进一步作了室内测定和大田防治试验,证实甲胺磷可以取代杀虫脒而应用于水稻生产.
Rice leaf roller is one of the main rice pests, since the promotion of chlordimeform control, has received significant results.But due to chlordimeform long residual effect, there are residues, the number of times and the use of time subject to certain restrictions, so the production There is an urgent need to find a new agent to replace Chlordimeform in the control of rice leaf roller C. 1979-1981 We screened a variety of pesticides and found that methamidophos has an excellent insecticidal effect on C. medinalis On 1982, further tests were conducted indoors determination and field control, confirmed that methamidophos can be substituted for chlordimeform and applied to rice production.
