Abstract: Five ideal agents for the prevention and control of viral diseases were screened out, including morinidine hydrochloride, amino-oligosaccharide, antichitin, ningnanmycin, viralin. Taking Enshi prefecture local agricultural use of self-retention species Mira as the research subject, combining relevant agronomic measures, the prevention and control effects of the above five agents were studied for viral diseases. The results showed that amino-oligosaccharide and mononidine had better control effect on potato virus disease, and the relative control effect was 55.06% and 44.95%, respectively, and the yield increase was 22.71% and 21.38%, respectively, compared with CK.
