In first and second years to study the nutrition balance in healthy and affected vineyards the leaf was sampled at various phonological stages, especially at flowering and verasion. Physical and chemical characters of soil and water irrigation with some testes such as bud germination, pollen germination, vegetative growth and infection rate were studied. During growth season vineyards were checked for pest and diseases infection and weather data were recorded too. Results showed that: Disorders rate in traditional training system were more than the cordon training system. Also the location and weather affected the rate.
