The diseases of Angelica sinensis were surveyed in the Minxian district of Gansu Province from 2012 to 2016 and fungicide for controlling leaf spot diseases were tested.In total,11 diseases have been identified in this region.These include nematode disease(Ditylenchus destructor),root rot(Fusarium sp.),brown spot(Septoria sp.),powdery mildew(Erysiphe heraclei),gray mold(Botrytis sp.),anthracnose disease(Colletotrichum dematium),sclerotinia(Sclerotinia sp.),water rot(Pseudomonas fluorescens),viral disease(ToMV),and two bacterial diseases.With regard to Angelica brown spot disease,treatment with 80% mancozeb,10% difenoconazole,70%thiophanate methyl,or 46.1%copper hydroxide reduced the disease index by64.83%,59.66%,53.84%,and 51.56%,respectively.With regard to bacterial leaf spot disease,treatment with 46.1% copper hydroxide,50% carbendazim,or 70% thiophanate methyl reduced the disease index by74.20%,59.67%,and 58.07%,respectively.These results provide the basis for the control of Angelica diseases in Minxian County of Gansu Province.
