Sensitivity analysis and point mutations in BcSDHB confer cyclobutrifluram resistance in Botrytis cinerea from China.

Botrytis cinerea is one of the most destructive pathogens worldwide. It can damage over 200 crops, resulting in significant yield and quality losses. Cyclobutrifluram, a new generation of succinate dehydrogenase inhibitors, exhibits excellent inhibitory activity against B.

Three point mutations in AaCYP51 combined with induced overexpression of AaCYP51 conferred low-level resistance to mefentrifluconazole in Alternaria alternata.

Tomato early blight is a significant disease that causes substantial losses to tomato yield and quality. Mefentrifluconazole, an isopropanol-azole subgroup of triazole fungicides, has been registered in China for controlling various plant diseases, including tomato early blight, grape anthracnose, and apple brown spot. However, limited information is available on the mefentrifluconazole resistance risk and mechanism in plant pathogens.

Resistance Risk and Resistance-Related Point Mutations in Target Protein Cyt b of the Quinone Inside Inhibitor Amisulbrom in .

Amisulbrom is a novel quinone inside inhibitor, which exhibits excellent inhibitory activity against phytopathogenic oomycetes. However, the resistance risk and mechanism of amisulbrom in are rarely reported. In this study, the sensitivity of 147 isolates to amisulbrom was determined, with an average EC of 0.
