以当前常用的3种杀螨剂螺虫乙酯、螺螨双酯、乙螨唑及其复配药剂为研究对象,采用随机区组设计,在苹果园进行了苹果全爪螨(Panonychus ulmi Koch)田间防治试验。结果表明:20%螺螨双酯悬浮剂和22.4%螺虫乙酯悬浮剂,不论是单剂还是与其它药剂混用,其速效性和持效性均很好;110g·L~(-1)乙螨唑悬浮剂单独使用速效性很差,不能迅速的降低螨口密度,需要与速效性好的杀螨剂联合使用。
In this paper, three commonly used acaricides, spirotetramate, spirobudiclofenacin and etoxazole and their compounded agents were selected as research objects. Randomized block design was conducted in apple orchards for Panonychus ulmi Koch Field control test. The results showed that both 20% spirodiclofen and 22.4% spirotetravone SC had good quick-acting and long-acting efficacies both in single-dose and in combination with other pesticides. 110g · L -1 Otozole SC alone is not effective enough to reduce mite density rapidly and needs to be combined with a quick-acting acaricide.
