BW - Bacterial Wilt
Scientific Name: Erwinia tracheiphila
Type: Bacterium
Bacterial Wilt is a disease that affects the growth of cantaloupes & melons, cucumbers, eggplants, gourds, pumpkins, squash, and tomatoes. Symptoms include wilting and drying of individual leaves. As the leaves wilt and shrivel, stems may dry out suddenly. Later, wilting spreads to entire branches and vines. Wilting will occur during the middle of the day during periods with high water stress. The vine may recover at night. Eventually, however, the entire vine will wither, collapse, and die. Bacterial wilt is spread from plant to plant through cucumber beetles that feed on cucumbers. The infected plants should be removed to avoid further infestation. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year. Use insecticides like Admire, Platinum, or Sevin in the spring, between April and June, before the cucumber beetles have a chance to lay eggs. The best option is to use disease resistant varieties.
