SV1是一种增效范围较广的农用增效剂,对多种杀虫剂具有增效作用。经室内毒力测定,氧化乐果与SV1以1:3(ai)混配对棉蚜防效增加4.19倍,对菜蚜防效增加3.07倍,对麦蚜防效增加2.69倍,对稻飞虱防效增加4.01倍;对鳞翅目幼虫表现为相加作用。杀虫毒力随混配剂中SV1成分的增加而提高,氧化乐果与SV1之比达1:3以上增效才显著。通过网室钵栽和田间防治棉蚜的系统观察,发现在防治效果相仿的情况下,SV1可使氧化乐果药效延长8~9天,用药量减少1/2~4/5。因此,认为SV1与氧化乐果混配,在生产中具有广阔的应用前景。
SV1 is a wide range of synergistic agricultural synergist, a synergistic effect on a variety of insecticides. The toxicity of Omethoate to SV1 was 4.19 times higher than that of SV1 by 3.0 times as much as control Times, the control effect on planthoppers increased 4.01 times; Lepidoptera larvae showed an additive effect. The insecticidal virulence increased with the increase of compound SV1, and the ratio of omethoate to SV1 was more than 1: 3. Through the systematic observation of potting and field control of cotton aphid in the net room, we found that SV1 can prolong the efficacy of omethoate by 8 to 9 days and decrease the dosage by 1/2 ~ 4/5 under the similar control effect. Therefore, it is considered that SV1 is mixed with omethoate and has broad application prospects in the production.
