How to recognize bacterial wilt?
The most obvious symptom of cucumber wilt is vines that have been well watered suddenly wilting. Before this happens though the leaves of your vines will exhibit dull green patches. However, the onset of the disease is so fast that you may never notice this dullness.
Plants usually are infected with the disease-causing bacteria long before they show any symptoms. When the vines wilt and collapse (usually about the same time that the first cucumbers are half grown), it is too late to prevent the disease.
