Silwet618在食心虫农药减量化防治中的应用研究

通过在不同果树上的田间药效试验,应用农用有机硅表面活性剂Silwet618作为桶混助剂,进行关于食心虫防治中的农药减量化研究。结果表明,在不影响防效的前提下,桶混稀释5000倍的Silwet618可使5%氯虫苯甲酰胺悬浮剂和2.5%高效氯氰菊酯微乳剂防治桃树上食心虫分别减量15%～24%和31%～32%,5%阿维菌素微乳剂防治苹果树上食心虫减量48%,20%虫酰肼悬浮剂和5%甲维盐水分散粒剂防治梨树上食心虫分别减量42%和63%。对于不同的药剂,减量程度不同,需要根据实际情况确定最佳施药方案。

Application Research on the Pesticide Reduction Control of Fruit Borer by Silwet618

This research focuses on the pesticide reduction control of fruit borer through field efficacy trials for fruit trees by using silicone Surfactant Silwet618 as tank mix adjuvant. The results show that, without influence to control effect, adding diluted 5 000 fold Silwet618 in the pesticide solution make the spray dosage of 5% chlorantraniliprole SC and 2.5% beta-cypermethrin ME respectively reduce by 15%-24% and 31% -32% in peach, 5% avermectin ME reduces by 48% in apple, and 20% tebufenozide SC and 5% of emamectin benzoate WDG respectively reduce by 42% and 63% in pear. The reduction levels change for different pesticides. So it is necessary to determine the best application methods according to the actual conditions.
