CucCAP Crop and Disease Management specialists Lina Quesada-Ocampo and Jonathan Schultheis collaborated with other Cooperative Extension specialists in NC to release a new full crop profile for the NC cucumber. The profile details worker activities; production practices, counties, and facts; pests including insects, pathogens, weeds, nematodes, and mites. Each pest is outlined by name (common and scientific), importance, symptoms, chemical controls, products/brands, biological controls, physical controls, and cultural controls.
Extension specialists and researchers from land-grant universities in the U.S. develop information from from research and Extension projects and collaborate with each other to produce production manuals for their reigon.
CucCAP researchers and stakeholders met on October 27, 28 & 29, 2022 to present and discuss the grant’s accomplishments, ongoing research, plans and expectations. Lina Quesada-Ocampo (NC State University), Mary Hausbeck (Michigan State University), Chris Smart (Cornell University), Anthony Keinath (Clemson University), Shaker Kousik (USDA-ARS), Jonathan Schultheis (NC State University), Daniel Tregeagle (NC State University), and Mary Lorscheider (NC State University Extension communicator) reported on the Integrated Disease Management Team’s progress.
As an undergraduate research assistant in the Quesada Vegetable Pathology Lab at NC State University, Jack Mascarennas assisted Research Specialist Mike Adams with cucurbit disease field trials conducted for the first CucCAP project.
CucCAP scientists Lina Quesada-Ocampo and Jonathan Schultheis will present:
Disease Management and Downy Mildew, Cultivars to Consider Growing in North Carolina
Pumpkin Spacing Considerations: Effects on Yield, Size and Fruit Uniformity
Watermelon Cultivar Evaluations in Fields with Minimal or High Levels of Fusarium Wilt
Potential Fusarium Wilt Management Strategies
CucCAP vegetable pathologist, Dr. Lina Quesada-Ocampo will be a keynote speaker at this conference.
Cucumber Team Publications and Presentations included in the 2021 Annual CucCAP Report.
Downy mildew caused by Pseudoperonospora cubensis is the most destructive foliar disease affecting cucurbit crops. Genomic studies by Dr. Lina Quesada-Ocampo and colleagues at North Carolina State University showed that different isolates preferentially infect different cucurbit crops. From this information, a multiplex PCR-based assay was combined with spore trapping to identify which crops are most at risk. These results can facilitate timely and crop-specific fungicide application prior to appearance of symptoms in sentinel plots.
