Abstract:
In the early stage of yam anthracnose, five kinds of bactericides were selected to control yam anthracnose in field. The efficacy trial results showed that 15% difenoconazole+15% propiconazole (Cuimiao) had the best effect on preventing and controlling yam anthracnose with a longer persistence, the control efficacies for which were 84.8% and 83.9% after 7 d and 14 d treatment, respectively. 45% prochloraz (Zengxian) and 10% difenoconazole (Kaigao) also had better control effect, and could be used as chemical agents for yams anthracnose prevention, alternatively.
