Sudden wilt
This disease is characterized by premature plant die off that frequently occurs after fruit set. The precise cause is not well determined, but a complex of environmental conditions and pathogen species, including Fusarium, Rhizoctonia, and Pythium. may be implicated. Extreme water logging or drought conditions that reduce plant resistance can contribute to watermelon sudden wilt.
The disease is unpredictable. The development of the disease occurs so quickly and without warning that control measures are impossible to implement. Practicing long-term rotation (at least 2 to 3 years out of cucurbits) to help prevent the build-up of these pathogens is best recommended. For Pythium control, provide good drainage and avoid excessive soil moisture by extending the intervals between irrigation and avoiding long irrigation periods. Fungicides have not proven effective in controlling sudden wilt.
