摘要
[Objective]The paper was to effectively control stem base rot of sweet potato.[Method]Chemical prevention and control test against stem base rot of sweet potato were conducted for consecutive three years from 2016 to 2018.[Result]The use of carbendazim or carbendazim+mancozeb,and carbendazim+embamycin had significant control effect on stem base rot of sweet potato.However,the applied concentration should be higher than the recommended concentration.Especially the concentration of 50%carbendazim WP should be no more than 300 times,and the prevention and control effect of 100 times dilution would be better.[Conclusion]The types and concentrations of prevention and control agents are determined in the test,which will provide certain basis for chemical prevention and control against stem base rot of sweet potato.
