摘要： The efficacy of a new fluorinated benzamide compound LH-2010A against Pseudoperonospora cubensis and its uptake-translocate behavior in cucumber plants were studied. Calculated EC50 was 6.70 mu g/mL, whereas fluopicolide was 7.67 mu g/mL. LH-2010A was absorbed by plants and translocated to other sites. Furthermore, the downward transportation observed was different from fluopicolide. The absorption of LH-2010A by cucumber roots was inhibited by low temperature, respiratory inhibitors, sucrose and amino acids indicating that the absorption is an active process.
