Downy mildew disease has been confirmed in North Florida watermelons. South Georgia and South Alabama watermelon producers should be wary since the disease can spread easily by the high winds being experienced this week.

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

Improved detection methods for CDM
CucCAP researchers develop improved detection methods for downy mildews infecting cucurbit crops. Management of cucurbit downy mildew relies on an intensive fungicide program. Timely alerts of appearance of sporangia can help growers to determine need to initiate fungicide sprays. Research by CucCAP scientists developed improved ability to detect airborne sporangia and distinguish among types that infect different kinds of crops. This improved methodology could be used as part of an advisory system to time fungicide applications to protect cucurbit crops.

Georgia vegetable disease update | AgNet Media
Cucurbit diseases such as downy mildew, powdery mildew, and gummy stem blight thrive in moist conditions. The current hot and dry weather conditions in Georgia have meant reduced disease pressure, which is normally prevalent this time of year.
