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.
