摘要：

为有效防治附子病毒病、霜霉病、白绢病和根腐病,筛选出高效、低毒、无公害的防治药剂,选用枯草芽孢杆菌可湿性粉剂（1000亿cfu/g）、异菌脲悬浮剂(500 g/L)、咯菌腈悬浮种衣剂(25 g/L)、22.5%啶氧菌酯悬浮剂、47%春雷·王铜可湿性粉剂、60%唑醚·代森联水分散粒剂、6%寡糖·链蛋白可湿性粉剂和吡唑醚菌酯乳油(250 g/L)8种药剂进行田间药效试验。结果表明：6%寡糖·链蛋白WP 对病毒病的田间防效最优,为71.03%~72.98%;250 g/L吡唑醚菌酯EC对霜霉病的防效最好,为70.97%~73.89%;500 g/L异菌脲SC对白绢病的防效最理想,为61.07%~69.80%;25 g/L咯菌腈FSC对根腐病的防效最佳,为61.26%~66.18%。试验筛选出防治附子主要病害的4种有效药剂,可在四川省附子种植区推广应用。

Abstract:

The paper aims to effectively control the virus disease (Cucumber mosaic virus, CMV), downy mildew disease (Peronospora aconiti), southern blight disease (Sclerotium rolfsii) and root rot disease (Fusarium solani) of Aconitum carmichaeli. The field control effects of eight fungicides, including Bacillus subtilis (100 billion cfu/g) WP, iprodione SC (500 g/L), fludioxonil FSC (25 g/L), picoxystrobin 22.5% SC, kasugamycin·copper oxychloride 47% WP, pyraclostrobin·metiram 60% WG, oligosaccharins·chain protein 6% WP, and pyraclostrobin EC (250 g/L), were evaluated. The results demonstrated that oligosaccharins·chain protein 6% WP was the most effective fungicide against the virus disease, the field control efficacy was 71.03%-72.98%. Pyraclostrobin EC (250 g/L), iprodione SC (500 g/L), and fludioxonil FSC (25 g/L) were highly effective to the downy mildew, southern blight, and root rot, respectively. The field control efficacy was 70.97%-73.89%, 61.07%-69.80%, and 61.26%-66.18%, respectively. The four effective fungicides were screened out in the experiment, which could be applied to A. carmichaeli cultivating area in Sichuan.
