The present application provides a kind of derivative of dual-target inhibitor structure, the compound has the structure of formula (I) as shown in formula (I): formula (I) wherein, in formula (I) R1 It is selected from phenyl, 2-fluorophenyl, 3-fluorophenyl, 4-fluorophenyl, 4-chlorophenyl, 4-bromophenyl, 4-trifluoromethylphenyl, 4-methylphenyl, 4-ethylphenyl, 4-isopropylphenyl, 4-methoxyphenyl, 4-nitrophenyl, 4-methylsulfonylphenyl, thienyl, pyridyl, 3,5-difluorophenyl, 3,5-dichlorophenyl, 3,4,5-trifluorophenyl;R2 It is selected from H,
halogen,
trifluoromethyl, R2 It is in arbitrary position substitution position, single substitution or multiple substitution.The present application uses the derivative of the dual-target inhibitor structure for the use of the agent for preventing and treating
plant pathogenic fungi.It can be seen that it has
inhibitory effect on various
plant fungi, and the
inhibitory effect in
sclerotinia is more significant.It has significant
inhibitory effect on
succinate dehydrogenase and
chitin synthase activity.
