CucCAP scientists find high prevalence of gummy stem blight resistance to common fungicides
The gummy stem blight fungus, Stagonosporopsis citrulli, is now resistant to fungicides in four chemical classes. The newest resistance is to fungicides in FRAC Code 3.
Cucumber field trials 2023
The Vegetable Pathology Lab at NC State conducts field trials each growing season to study plant pathogens, resistance of plant varieties to pathogens, and vegetable disease management strategies. When a field trial is harvested, the crop is weighed, graded, and evaluated for disease damage and marketability.
CucCAP watermelon team | super-pangenome for watermelon
Scientists have constructed a comprehensive ‘super-pangenome’ for watermelon and its wild relatives, uncovering beneficial genes lost during domestication that could improve disease resistance and fruit quality of this vital fruit crop.
Plant Health 2023 Awards
Two members of the CucCAP Integrated Crop and Disease Management Team were selected to receive APS awards in honor of their significant contributions to the science of plant pathology at Plant Health 2023.
CucCAP scientists perform genome-wide association study to identify resistances to Pseudomonas leaf spot in watermelon
Citrullus amarus was screened for resistance to Pseudomonas leaf spot. Genetic markers associated with resistance to P. syringae and other diseases were identified. The results will facilitate breeding for resistance to PLS in watermelon.
2023 Watermelon trial for Fusarium resistance
Delaying transplanting until the soil has warmed to about 81 degrees at a 4-inch depth can reduce the number of plants with Fusarium wilt.
Eleanor and Fascination are partially resistant cultivars that have been shown to perform better when Fusarium wilt is present. But grafting is more effective…and more expensive
