Plant Disease Management Techniques

The distribution of chestnut blight caused by Cryphonectria parasitica was surveyed in the forests of Sopron Hills. The infection rate was different in the forest subcompartments ranging up to 35%. Six vegetative compatibility types were detected, two of them were wide spread and present all of the hills. Converted hypovirulent strains were tested for practical control of the disease. More than 90% of the treated trees healed in eight years after the inoculation in the experimental plot.
