Abstract

Susceptibility of wounds of the European beech bark to infection by Neonectria coccinea and efficiency of the wound treatment.

Abstract

An intact bark of European beech (Fagus sylvatica) is not an infectious court for Neonectria coccinea since the fungus is not able to overcome the mechanic barrier of bark. Wounds are infectious courts for the fungus and the result of the infection is the beech bark disease. Deeper wounds are more susceptible to infection than shallow wounds. Infection periods of wounds last approximately 0 days in spring, 1 day in summer, 7 days in autumn and 3 months in winter. However, fresh wounds are the most susceptible to infection in autumn. Wound treatment should be applied while wounds are susceptible to infection. If wounds are coated by fungicidal suspension prior to infection, necrotic lesion will not set in. It is the most effective in autumn and on the same day the wound was made. Curing treatment has little reason.
