A triazole derivative, a preparation method therefor, and a use thereof, relating to the technical field of organic synthetic drugs. The structure of the triazole derivative is shown in formula I, wherein R1 and R2 in formula I are H, Cl, Br, —CF3, —CH(CH3)2, or —OCH3, and R1 and R2 are not H at the same time; R3 is —CH2— or —COCH2—; X and Y are N or C, and X and Y are not C at the same time, and X and Y are not N at the same time. The triazole derivative has a certain inhibitory effect on the pathogens of various crop diseases, and fewer toxic side effects for plants. The preparation method for the triazole derivative is simple. |
