试验表明,31%三拂ME对稻纵卷叶螟有较好的防治效果,防治效果可达90%以上。但不同情况所施用的药量不同,在1~2龄低龄幼虫建议每667m2用50~60ml,在3~4龄高龄幼虫建议每667m2用70ml。
Tests showed that 31% MEI ME had a better control effect on C. medinalis and the control effect could reach more than 90%. However, in different situations, the dose applied varies from 50 to 60ml per 667m2 for young larvae of 1 to 2 years old and 70ml per 667m2 for larvae of 3rd to 4th instar larvae.
