Prevention & Control of Physiological Disorders of the Vine
Eutypa is prevalent at Vogelzang Vineyard in Happy Canyon, San Bernadino County, California. It constantly affects around 10% of the vineyard. There is no cure. They combat the disease by training a sucker to replace the affected trunk. Vines that are too much affected are ripped out plot by plot. Symptoms include: curling, yellow leaves, necrosis, unhealthy / underripe fruit bunches early in season.
