| 【目的】评价惠州市银农科技股份有限公司研发的5%甲氨基阿维菌素苯甲酸盐（甲维盐）水分散粒剂（WG）对鳞翅目害虫的田间防效。【方法】采用田间药效小区试验和五点取样法调查并计算供试药剂在甘蓝上对甜菜夜蛾和在水稻上对稻纵卷叶螟的田间防效。【结果】供试药剂5%甲维盐WG 有效成分7.5 g/ha、12.0 g/ha和15.0 g/ha喷施后7天对甜菜夜蛾的防治效果分别为82.87%、89.37%和91.02%，喷施后14天对稻纵卷叶螟的防治效果分别为90.32%、94.20%和98.03%。差异显著性分析表明：供试药剂12.0 g/ha 处理后7天和14天对甜菜夜蛾的防效显著高于对照药剂5%甲维盐WG（某公司）和5%甲维盐乳油（EC）处理的防效；供试药剂12.0 g/ha 处理后14天的防效与对照药剂5%甲维盐WG（某公司）处理的防效相当，显著高于5%甲维盐乳油（EC）处理的防效。【结论】惠州市银农科技股份有限公司研发的5%甲维盐WG对甜菜夜蛾和稻纵卷叶螟具有较好的防治效果，持效期较长，对农作物无药害，对有益生物无不良影响。 |

| 【Objective】The aim is to evaluate the field control of 5% emamectin benzoate water dispersible granule (WG) against Lepidoptera Pests, and the 5% emamectin benzoate WG was produced by Huizhou Yinnong Technology Co., Ltd.【Method】Field plot test and five point sampling method was applied to test the field control of 5% emamectin benzoate WG against Spodoptera exigua and Cnaphalcrocis medinalis.【Result】After 7d spraying, the field control of 5% emamectin benzoate WG （active ingredient，ai））of 7.5 g/ha, 12.0 g/ha, 15.0 g/ha against Spodoptera exigua were 82.87%, 89.37%, 91.02% respectively; After 14d spraying, the field control of 5% emamectin benzoate WG （ai））of 7.5 g/ha, 12.0 g/ha, 15.0 g/ha against Cnaphalcrocis medinalis were 90.32%, 94.20%, 98.03% respectively. Significant difference analysis indicated that the 7d and 14d field control of the 5% emamectin benzoate WG against Spodoptera exigua were higher than 5% emamectin benzoate WG (other company) and 5% emamectin benzoate emulsifiable concentrate (EC); the 14d field control of the 5% emamectin benzoate WG against Cnaphalcrocis medinalis was higher than 5% emamectin benzoate emulsifiable concentrate (EC), and there was no difference compared to 5% emamectin benzoate WG (other company). 【Conclusion】The 5% emamectin benzoate WG produced by Huizhou Yinnong Technology Co., Ltd showed good field controls against on Spodoptera exigua and Cnaphalcrocis medinalis. Moreover, It had a long duration, no harm to crops and no adverse effects on beneficial organisms. |
