为寻求防治顽固性害虫稻纵卷叶螟的高效农药,通过室内配方筛选试验,甲维盐与毒死蜱复配1:99配比对稻纵卷叶螟杀虫活性最高,共毒系数206.65,增效显著。田间药效试验中,20%甲维.毒死蜱WP速效与持效性均好,亩用80～100g,对稻纵卷叶螟杀虫效果为88.6%～94.3%,保叶效果81.9%,对水稻无不良影响,是替代高毒农药的优良药种。
In order to seek efficient pesticides for the prevention and treatment of indolent pest thrips leafroller, through the indoor formula screening test, the ratio of 1: 99 with the ratio of 1: 99 and the ratio of chlorpyrifos to insecticide is the highest, with a total toxic coefficient of 206.65 Significant effect. Field efficacy trials, 20% of methylvimentic chlorpyrifos WP fast and maintain good, mu with 80 ~ 100g, insecticidal effect on the rice leaf roller Cnaphalocarpa is 88.6% ~ 94.3%, leaf protection effect of 81.9%, on No adverse effects of rice, is an excellent alternative to highly toxic pesticides.
