Abstract

Abstract:

In order to improve the seed quality of Brassica oleracea and reduce the incidence of seedling diseases, this study investigated the effects of different concentrations of hymexazol and metalaxyl-M·fludioxonil seed coating agents on seed germination, seedling growth, and disease occurrence of Brassica oleracea. The results showed that the seed germination potential, seed germination rate, and emergence rate of two Brassica oleracea varieties showed a trend of first increasing and then decreasing after being mixed with the same pesticide at different concentrations. When the concentration of hymexazol seed coating agent is 0.10%, the seeds germination potential and seeds germination rate were higher than other concentrations of hymexazol seed coating agent treatments; The germination potential and germination rate of the seeds treated with 3 mL·kg^-1 metalaxyl-M·fludioxonil seed coating agent were higher than those treated with other concentrations of metalaxyl-M·fludioxonil seed coating agent, and it was also the most effective among all treatments. The research results provide important reference and guidance for the high-quality seed processing technology of Brassica oleracea.
