CucCAP researchers find that different downy mildew populations have different types of fungicide resistance

Downy mildew caused by Pseudoperonospora cubensis causes severe losses in commercial cucurbit crops. Chemical control is hampered by emergence of pathogen resistance to several fungicides. Genetic analyses by the Quesada laboratory at NC State found that different clades of P. cubensis vary for the predominant mutations conferring resistance. These findings of clade-specific resistances can facilitate the design of more effective fungicide programs tailored to crop and region.
