0.5%阿维菌素颗粒剂防治黄瓜根结线虫病药效试验

Efficacy of 0.5% Granular Abamectin on Cucumber Root Knot Nematode Disease

以"津东8号"黄瓜为试材,以清水为对照,研究了泰安市现代农业科技有限公司生产的不同浓度的0.5%阿维菌素颗粒与深圳诺普信农化股份有限公司生产的0.5%阿维菌素颗粒剂对黄瓜根结线虫病的田间药效。结果表明:泰安市现代农业科技有限公司生产的0.5%阿维菌素颗粒剂2 000、3 000、3 500g/667m2对黄瓜根结线虫病的防效在66.61%～74.63%之间,3 000g/667m2相同剂量下的2个厂家的0.5%阿维菌素颗粒防效差异不显著。

Taking ＇Jindong No 8＇ cucumber as the experiment material, and water as control, the efficacy of 0. 5~ granular abamectin of various concentrations made by Tai ＇an Modern Agricultural Science and Technology Co. , Ltd and Shenzhen Noposin Co. , Ltd on cucumber root knot nematode in field were studied. The results showed that the efficacy ranged from 66. 61% ~74. 63% when applying 0. 5% granular abamectin of various concentrations made by Tai ＇an Modern Agricultural Science and Technology Co. ,Ltd in concentration of 2 000,3 000 and 3 500 g/667m2. No significant differences showed when applying 0. 5% granular abamectin made by both companies when applying 3 000 g/667m2.
