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.
Whiteflies a Factor in South Florida Crops
According to the South Florida Pest and Disease Hotline, up to eight whitefly adults have been observed on melons in the Immokalee, Florida area. Scouts report between 15% to 60% of plants having one or multiple adults.

Florida vegetable specialist recommend virus prevention strategy
Whiteflies cause feeding injury issues in vegetables and transmit two viruses: cucurbit leaf crumple virus and cucurbit yellow stunting disorder virus. Sanitation of vegetable crops susceptible to whiteflies remains a key management strategy for Florida producers.
