Their average frequency is 85.23% . This indicates that the fungicide still has good antibacterial effect. Only a few strains are high resistant and the average frequency is 8.93% . The results of this study will provide a theoretical basis for the control of T. tomentosum by Prochloraz Manganese Chloride.
