JM-1号植物免疫剂对白粉病的田间防治作用

为筛选防治大型蜜瓜白粉病的高效、低毒、安全植物免疫剂，对 JM-1号原液、JM-1号稀释十倍、粉巧、 清水四种药剂进行田间药效试验。结果表明：粉巧化学药剂处理的防效较高，JM-1号稀释十倍植物免疫剂处理防效较差。未发病植株JM-1号植物免疫剂病指防效分别为18.54%和21.51% ;未发病植株JM-1号稀释十倍植物免疫剂病指防效分别为 5.34%和7.49％；未发病植株粉巧化学药剂病指防效分别为79.98%和70.51% ；发病植株JM-1号植物免疫剂病指防效分别为18.78％、19.37% 和21.36％。发病植株JM-1号稀释十倍植物免疫剂病指防效分别为24.38％、17.86%和12.65%。发病植株粉巧化学药剂病指防效分别为77.56％、78.36%和78.84%。

Field Control of Powdery Mildew with JM-1 Plant Immune Agent

In order to screen effective, low toxic and safe plant immune agents against powdery mildew of large honeydew melon, field efficacy tests were carried out on JM-1 stock solution, JM-1 diluted ten times, Fenqiao and clear water. The results showed that the control effect of Fenqiao chemical agent treatment was higher than that of JM-1 diluted 10 times plant immune agent treatment. The finger control effects of JM-1 plant immune agent disease were 18.54% and 21.51%, respectively; the finger control effects of JM-1 plant immune agent disease with 10-fold dilution were 5.34% and 7.49%, respectively; the finger control effects of powdery chemical agent disease of non-infected plant were 79.98% and 70.51%, and the finger control effects of JM-1 plant immune agent disease were 18.78%, 19.37% and 21.36%, respectively. The control effects of JM-1 plant with 10 times dilution were 24.38%, 17.86% and 12.65% respectively. The finger control effects of the diseased plants were 77.56%, 78.36% and 78.84% respectively.
