Symptoms of yellow vine decline begin to appear approximately 2 weeks before fruit maturity. The disease may appear initially as stunting of plants and/or intense yellowing of foliage, followed by a slow decline in plant health. In some cases, a sudden collapse of vines may occur with no other symptoms. Vascular tissue (phloem) from crowns of affected plants is often discolored, appearing light brown rather than a healthy translucent green.
