It is never too early for watermelon producers in the Southeast to start thinking about management options for gummy stem blight disease. As Clemson Extension vegetable pathologist Tony Keinath puts it, “Early is on time.”
CucCAP Disease Management Team
The Disease Management Team contributions to the CucCAP project include English and Spanish factsheets about cucurbit crop and disease management strategies including images of disease symptoms for crop producers, articles about cucurbit plant pathology, and articles about the team’s research efforts and accomplishments.
CucCAP scientist examines economic impacts of reduced fungicide efficacy against downy mildew
Resistance to fungicides is a concern with cucumber downy mildew, Pseudoperonospora cubensis clade 2. These fungicides still suppressed downy mildew well enough that yields of marketable-sized fruit of a susceptible slicing cucumber were much better than not spraying.
Early Career Scientist Spotlight | Libby Indermaur
Libby is identifying which of Michael Mazourek’s Cucurbita moschata and C. maxima breeding lines are: 1) resistant to powdery mildew and 2) candidate replacements for the susceptible cultivars used in the processing industry.
Cucurbit Disease Management Factsheets | MSU
These fact sheets are updated annually and posted on the Hausbeck lab website at Michigan State University.
Cucurbit Disease Management Resources | NC State
The NC State Vegetable Pathology Lab has developed a series of fact sheets describing cucurbit diseases and providing information on how to manage the pathogens causing them. The CucCAP team in collaboration with the Quesada lab developed Spanish translations of these factsheets.
Cucurbit Disease Management Factsheets | Clemson
These fact sheets are published at Land-Grant Press by Clemson Extension and contain information pertinent to South Carolina. Diagnostics and management may vary in other states or countries.
CucCAP researchers evaluate disease control options for downy mildew on pickling cucumber
Cucurbit downy mildew (CDM), is an economically significant disease of cucurbitaceous crops in the Eastern United States (US). Cucumbers are particularly susceptible and as a result, disease management of this pathogen relies heavily on fungicide use.
Cucurbit Disease updates | June 2022
On June 1, the CucCAP team observed Cucurbit Downy Mildew on cucumbers in North Carolina and Fusarium wilt on watermelon in South Carolina.
