Under the optimized reaction conditions,dimethomorph was synthesized using catechol as the starting material.Based on the solubility difference of different isomers of dimethomorph in the same solvent,(Z)-isomer and(E)-isomer were separated,and(Z)-dimethomorph was obtained.(E)-isomer was racemized and cycled.The inhibitory effects of(Z)-dimethomorph on Phytophthora capsici were determined by the mycelial growth rate method.The results showed that(Z)-dimethomorph had a good antibacterial effect on Phytophthora capsici.
