Abstract

The invention discloses a prevention and treatment method for Chinese angelica coarse barkdiseases. The problems that due to the fact that in the prior art, when only agricultural prevention and treatment are adopted, the effect is not good, when only chemical prevention and treatment are adopted, pesticide residues exist, and the quality of Chinese angelica is damaged are solved. By adopting the combination of agricultural control and chemical control, the method comprises the following steps of plot selection and prevention and treatment in processing, prevention and treatment in seedling growing process, prevention and treatment in the transplanting stage, root-irrigation prevention and treatment in the medicine formation period. According to the method, by adopting the combination of agricultural prevention and treatment and chemical drug prevention and treatment, prevention and treatment of Chinese angelica coarse barkdiseases can be performed, the effect is exact, pesticide residues are not caused, and the quality of the Chinese angelica is not affected.
