Abstract:: The co-toxicity of carbamic acid，fluoxastrobinole and their mixture against cypress of withering disease pathogens，holly leaf spot disease pathogens，lawn frost mildew pathogens，oleanders speckle disease pathogens and roses gray mildew pathogens were studied based on the mycelial growth rate method in the laboratory.The results indicated that when the ratio of the mixture of carbamic acid and fluoxastrobinole was 1∶3，the co-toxicity cofficient (CTC) against mycelial growth of cypress of withering disease pathogens and holly leaf spot disease pathogens were 195.03 and 201.48， respectively.When the ratio of the mixture was 3∶1，the CTC against mycelial growth of lawn frost mildew pathogens was 196.29.When the ratio of the mixture was 1∶5，the CTC against mycelial growth of oleanders speckle disease pathogens was 195.27.When the ratio of the mixture was 1∶10，the CTC against mycelial growth of roses gray mildew pathogens was 198.89.The results suggested that carbamic acid and fluoxastrobin had significant synergistic activity against five landscape plant phytopathogenic fungi when combined by appropriate ratio.
