Effective Fungicides and Optimum Application Time for Peanut Scab Control

摘要: 通过田间试验, 筛选花生疮痂病防治的有效药剂并研究其防治适期。结果表明, 所研究的13种药剂均有一定的防治效果, 以60%唑醚·代森联水分散粒剂、70%甲基托布津可湿性粉剂、10%苯醚甲环唑水分散粒剂、苯甲·丙环唑乳油防治效果较好, 增产幅度较大。以爱苗为试验药剂, 通过研究比较不同喷药时间和喷药次数的防治效果, 结果表明在未发病前喷施爱苗防治效果最好, 在发病初期连续喷施2次的防治效果好于只喷施1次。

Abstract: Fungicides effective for peanut scab disease control were evaluated, and their optimum application time determined.Thirteen fungicides were tested in the field.They all showed varied degrees of efficacy.Among them, 60% pyraclostrobin, 70% thiophanate-methyl, 10% difenoconazole, and benzoic propiconazole performed better than the others, with significantly improved crop yields as a result.For demonstration, the effects of time and frequency of spraying Armure on the plants were evaluated.The result showed that the best application time was before the pathogenesis appeared.Once the disease was detected, spraying twice consecutively was better than a single application.It was also recommended that these agents to be applied alternatively to reduce possibility of drug-resistance by the pathogen.
