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.

CucCAP scientists translate genomic studies into novel detection method for precision management of downy mildew outbreaks
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.
