Introduction Cucurbit yellow vine disease (CYVD) is an emergent disease in the United States caused by the bacterium Serratia ureilytica, and it commonly affects zucchini, squash, watermelon, and melons. The pathogen that causes CYVD is transmitted by the squash bug (Anasa tristis, Figure 1), and other potential vectors include the striped cucumber beetle (Acalymma vittatum)…Read more about Pathogen Spotlight: Serratia ureilytica Causing Cucurbit Yellow Vine Disease[Read More]



An average-yielding watermelon crop in an acre accumulates approximately 150 pounds of both nitrogen and potassium in the vegetative tissue and fruit. These nutrients are supplied by the soil’s existing nutrient pool and through supplemental fertilizer applications. Soil testing is a valuable tool for assessing what nutrients are present in soils and the amount of…Read more about Lessons Learned: Nitrogen Fertilizer Management in Indiana Watermelon Production[Read More]
