甲维盐泡腾片对大豆蚜虫防治效果研究

Study on the Control Effect of Emamectin Benzoate Preparation on Aphis Glycines Matsumura

为了明确优化工艺下制备的甲维盐泡腾片的田间药效情况,以大豆田常用药剂甲维盐可溶性颗粒剂为对照,进行田间小区药效试验.结果表明,在发病初期施药后,甲维盐泡腾片三个处理剂量组对大豆蚜虫的平均防治效果在64.60～70.85%之间,药效随着用剂量提高而增加,制剂的持续有效期为12d,甲维盐泡腾片对大豆蚜虫的防治效果具有显著差异.

In order to identify the optimization process of emamectin benzoate effervescent tablets preparation in soybean field,comparing with emamectin benzoate soluble granules,pharmaceutical effect experiments were conducted.The results show that in the initial stage after applying pesticide,three treatment groups of emamectin benzoate effervescent tablets average control effect were in 64.60 ~ 70.85%,the efficacy and the dosage increased together,valid sustained time was 12d,emamectin benzoate effervescent tablets preparation had significant differences in the control effect to aphis glycines matsumura.
