Technical Abstract: An unusual disease on cucurbit crops has been recognized throughout Central Texas and Oklahoma. Based on characteristic symptoms, it is called yellow vine. The organism causing the disease has not been identified, although recent evidence indicates that a bacteria-like organism is associated. The disease is difficult to diagnose and may be confused with other common diseases on cucurbits, such as Fusarium wilt. This publication gives a detailed description and photographic depictions of the disease symptoms. A disease diagnostic chart provides a helpful aid for identifying several vine decline diseases, including yellow vine. At present there are no satisfactory control measures for yellow vine. However, empirical evidence indicates that insects may vector the disease. Weekly insecticide applications have provided some control of yellow vine on squash. Preliminary observations indicate that seedless cultivars of watermelon are at least tolerant to the disease.
