研究了新烟碱类、有机磷类、双酰胺类、大环内酯类等10种杀虫剂对稻纵卷叶螟的田间防治效果并进行评价。结果表明,药后7 d,24%甲氧虫酰肼悬浮剂、150 g/L茚虫威悬浮剂的保叶效果最好,分别为92.81%、90.36%;10%四氯虫酰胺悬浮剂、22%氰氟虫腙悬浮剂、20%氟苯虫酰胺水分散粒剂、20%氯虫苯甲酰胺悬浮剂、10%溴氰虫酰胺油悬浮剂的保叶效果在74.50%~87.13%之间,药剂间差异不显著。药后14 d,保叶效果多数比药后7 d的高,24%甲氧虫酰肼悬浮剂、150 g/L茚虫威悬浮剂、10%四氯虫酰胺悬浮剂、22%氰氟虫腙悬浮剂、20%氟苯虫酰胺水分散粒剂、20%氯虫苯甲酰胺悬浮剂的保叶效果在79.14%~92.48%之间,药剂间差异不显著。从杀虫效果来看,药后7 d,150 g/L茚虫威悬浮剂、22%氰氟虫腙悬浮剂、20%氟苯虫酰胺水分散粒剂杀虫效果均达到了100%;24%甲氧虫酰肼悬浮剂、10%四氯虫酰胺悬浮剂、20%氯虫苯甲酰胺悬浮剂、10%溴氰虫酰胺油悬浮剂、45%稻散·毒死蜱乳油、720 g/L丙溴磷乳油6种药剂的杀虫效果均在80%以上;5%甲维盐水分散粒剂的杀虫效果最差,为64.71%。药后14 d,10%溴氰虫酰胺油悬浮剂的杀虫效果显著低于其他9种药剂,仅为61.90%;其他9种药剂的防虫效果均在90%以上,药剂间差异不显著。生产实践中应轮换使用双酰胺类、甲氨基阿维菌素苯甲酸盐、茚虫威、氰氟虫腙、有机磷类防治稻纵卷叶螟。
The control effects of 10 insecticides such as neonicotinoids, organophosphates, bisamides, macrolides on rice leaf roller were evaluated and evaluated. The results showed that the leaf protection effect of 24% methoxyfenozide and 150 g / L indoxacarb was the best at the 7th day after drug treatment, which were 92.81% and 90.36% respectively. The 10% , 22% metaflumizone suspension, 20% flubendiamide water dispersible granules, 20% chlorantranilone suspension and 10% bromoxetan oil suspensions showed 74.50% ~ 87.13% Between the pharmacy differences were not significant. On the 14th day after drug treatment, most of the leaf-holding effects were higher than that of the 7th day after treatment, and 24% methoxyfenozide suspension, 150 g / L indoxacarb suspension, 10% tetrachloroxetine suspension and 22% Penem hydrazone suspension, 20% flubendiamide water dispersible granules, 20% chlorantranilone suspension preservative effect in 79.14% ~ 92.48%, no significant difference between the drugs. From the insecticidal effect, the insecticidal effect of 150 g / L indoxacarb, 22% metaflumizone and 20% diflubenzuron water dispersible granules all achieved 100% after 7 days of treatment. 24% methoxyfenozide suspending agent, 10% tetrachloroxetine suspending agent, 20% chloramphenicol suspension, 10% bromoxetine oil suspending agent, 45% The insecticidal effect of 6 pesticides of L-glyphos-drip-lactoferrin was above 80%. The insecticidal effect of 5% A-dimensional salt water dispersible granules was the worst, which was 64.71%. On the 14th day after treatment, the insecticidal effect of 10% bromothiramide oil suspending agent was significantly lower than that of the other nine agents, only 61.90%. The other 9 kinds of pesticides had an anti-insect effect of over 90% with no significant difference between the two agents. Production practice should be the rotation of the use of bisamide, emamectin benzoate, indoxacarb, metaflumizone, organic phosphorus prevention and control of rice leaf roller.
