Abstract
Disease incidence and favorable condition on disease severity is evaluated. W. carpophilus isolated of infected orchards. For fungus overwintering method in buildup were carried out bud washing by centrifuge and spot culturing on nutrient mediums. Evaluation of shot hole in different areas showed that cultivars response to this disease is fixed inside of a climate but it is differ in different areas to each other. Fungus germination optimum was indicated 95% at 15˚C and its minimum 0.5% at 1˚C in experimental conditions. Fungus overwintering were confirmed as hyphae and conidia inside of bud and as hyphae in twig spots. The result of study indicating climatic effective role that is dominant in area in disease incidence and severity.
