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。
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 .
