| Abstract: | Strobilurins are a class of important agricultural fungicides that are used widely in plant protection. To find new strobilurin analogues with high activity against resistant pathogens, a series of new strobilurin derivatives bearing 1,2,4‐triazole oxime ether side chain 3a , 3b , 3c , 3d , 3e , 3f , 3g , 3h were designed and synthesized. Their structures were confirmed by IR, 1H NMR, EIMS, and elemental analyses. Bioassays indicated that some of the compounds showed good fungicidal activities in the concentration of 50 mg/L. For example, compound 3f possessed 100%, 100%, and 95.5% inhibition against Fusarium omysporum, Physalospora piricola Nose, and Gibberella saubinetii at the concentration of 50 mg/L, respectively. |
