Florida cucurbit pest and disease reports
The January South Florida Pest and disease hotline reported that Whitefly pressure continues to range from low to moderate. Cucurbit downy mildew and powdery mildew are active in squash and cucumbers.
CucCAP researchers develop new methods for detection and analysis of downy mildew pathogen on cucumber
Researchers in Dr. Mary Hausbeck’s group at MSU have developed a highly sensitive DNA-based protocol to genetically distinguish between spores of cucumber downy mildew and hop downy mildew from spore trap samples. The enhanced sensitivity enables detection 5-10 days before symptoms appear in cucumber fields, providing a broader window for initiation of chemical control.
Cucurbit Downy Mildew reported in Florida
Downy mildew is a problem for Florida’s cucurbit farmers. The disease has been reported recently in cucumber, squash, and watermelon fields.
Anthracnose Awareness | VSCNews
Anthracnose is a disease noticed on cucurbits in warm and high moisture conditions. The symptoms are noticed on leaves as necrotic lesions with or without cracked centers.
