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.

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.
Cucurbit Genetics Cooperative Reports #44 & 45
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.
Early Career Scientist Spotlight | Bidisha Chanda
Before her current position as a Genetic Purity Lab Manager in the Quality Assurance Department at Sakata Seed America, Inc., in Salinas California, Bidisha Chanda worked for the USDA and conducted research for the CucCAP watermelon team at the US Vegetable Laboratory in Charleston, South Carolina.
CucCAP scientists examine mechanisms of watermelon resistance to viral infection
Watermelon production in the U.S. and around the world faces serious threats by viral diseases, including aphid-transmitted potyviruses: papaya ringspot virus (PRSV) and zucchini yellow mosaic virus (ZYMV). In a recent study, a CucCAP team examined expression of anti-microbial/anti-viral, ribosome-inactivating proteins (RIPs) in watermelons in response to inoculation with PRSV. The PRSV-resistant citron watermelon (Citrullus amarus) exhibited high RIP expression, versus low expression in plants of the susceptible, cultivated “Charleston Gray” watermelon. This finding may offer additional genetic and genomic resources for improving potyvirus-resistance in watermelon cultivars.
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.
Cucurbit Downy Mildew Management
CucCAP plant pathologist, Anthony Keinath published a factsheet on cucurbit downy mildew management with sections on symptoms and signs, how cucurbit downy mildew spreads, cultural practices to limit cucurbit downy mildew, and spraying for cucurbit downy mildew.
