| 摘 要： | 本文评价了六种新农药对单季稻主害代稻纵卷叶螟的田间防治效果。结果表明，药后5天，5%甲维盐11.25 g（有效含量/公顷，下同）、10%阿维?氟虫双酰胺60 mL和24%氰氟虫腙216 mL对稻纵卷叶螟的防效在95%以上，32%丙溴?氟铃脲288 mL、20%氯虫苯甲酰胺30 mL和14.5%甲维?毒死蜱211.5 mL的防效在73.5%-83.1%。药后12天，丙溴?氟铃脲和氰氟虫腙的防效为74.1%～82.7%，阿维?氟虫双酰胺和氯虫苯甲酰胺的防效为62.9%～65.6%，甲维盐和甲维?毒死蜱的防效在50%以下。药后31天，除丙溴?氟铃脲和氯虫苯甲酰胺还有40%防效外，其它药剂无防效。氰氟虫腙、氯虫苯甲酰胺、阿维?氟虫双酰胺的保叶效果最好，药后5-12天为68.5%～78%，显著高于甲维盐、丙溴?氟铃脲和甲维?毒死蜱（53.3%～69.9%）。药后31天甲维盐和甲维?毒死蜱的保叶效果差在26%以下，其它药剂仍有45%-62%保叶效果。

| Abstract: | To understand the control effect of six newly insecticides on the 3rd generation of rice le-afroller,Cnaphalocrocis medinalis of single-season rice was evaluated through field spray in northwest mountainous areas of Zhejiang province in the year of 2009.The results showed that on the 5th day after spraying,control efficiency of 5% methylamino abamectin benzoate 11.25 g（a.i /hm^2,the following unit as here）,10% avermectins·flubendiamide 60 mL and 24% metaflumizone 216 mL on C.medinalis were more than 95%,32% profenofos·hexaflumuron 288 mL,20% chlorantraniliprole 30 mL and 14.1% methylamino abamectin benzoate chlorpyrifos 211.5 mL were 73.5%-83.1%.On the 12 th day after spraying,control effects of profenofos hexaflumuron and metaflumizone were 74.1%-82.7%,avermectins·flubendiamide and chlorantraniliprole were 62.9%-65.6%,methylamino abamectin benzoate and methylamino abamectin benzoate·chlorpyrifos were less than 50%.On the 31st day,except control effect of profenofos hexaflumuron and chlorantraniliprole still had about 37.8%-39.0%,other insecticides had no control efficacy.Leaf-protecting effects of metaflumizone,chlorantraniliprole,avermectins·flubendiamide were 68.5%-70.3% for 12 d after spraying,and were significantly high than those of methylamino abamectin benzoate,profenofos·hexaflumuron and methylamino abamectin benzoate·chlorpyrifos（54.0%-61.7%）.On the 31st day,leaf-protecting effect of methylamino abamectin benzoate and methylamino abamectin benzoate·chlorpyrifos were lower than 27%,and other insecticides still had 44%-62%.It is concluded that methylamino abamectin benzoate,avermectins·flubendiamide and metaflumizone have good rapidly effect,shorter effect-lasting period,and profenofos·hexaflumuron,chlorantraniliprole have both better effects and longer effect-lasting period. |
