Definitions

  • the invention relates to the use of light-resistant polyurethane resin lacquers as wound dressings on damaged trees, especially in tree surgery and in general in tree care.
  • the object of this use of polyurethane resin varnishes as tree varnish according to the invention is to seal branch cut-out areas, bark damage, large areas treated by tree surgery as well as drilling channels for securing anchors and securing materials to be introduced to trees in a waterproof and long-term weatherproof manner.
  • This ensures that the vital wood substance located under the sealing surface can continue to fulfill its biological functions, so that a protective wood layer can be built up from the tree under the sealing and drying out and thus crack formation in the damaged surface can be prevented.
  • this prevents further mudding under the wound closure surface, so that the use of polyurethane resin lacquer as tree lacquer according to the invention makes it useful for the first time to treat large areas with architectural treatment.
  • the result is drying out of the treated area with subsequent crack formation and death of the wooden cells located under the treated area, so that no natural protective wood Education is possible, but re-induction takes place due to the moisture, fungal spores and microorganisms.
  • DE-OS 3044499 describes a wound closure agent for tissue-injured plants containing bark-green or bark-gray dyes, which is based on an aqueous dispersion or emulsion of plastics or natural resins.
  • This preparation which is widely available on the market at times, does not fulfill the task of protecting wounds on trees.
  • the natural formation of protective wood directly under the wound closure agent does not take place.
  • the treated damaged area dries out and becomes cracked (moisture and microorganisms enter).
  • the onset of callus formation lifts the covering off the damaged area (moisture and harmful organisms occur).
  • the agent itself serves as a breeding ground for various fungi, so that fungicide additives are necessary to prevent this.
  • 'tree lacquer' no addition of fungi and insecticides is required.
  • a clean damaged or cut surface pretreated down to healthy wood is sealed by sealing the tree varnish against moisture loss, which prevents cracking.
  • existing fungal spores or other pathogens are enclosed and inactivated in the seal, so that there is no need to add toxic substances which would simultaneously kill the vital wood areas under the seal and prevent immediate formation of protective wood.
  • Protective wood layers are mechanically and chemically reinforced wood areas that the tree builds up against damaged areas in order to make it more difficult or prevent wood destroyers such as microorganisms, fungi and insects from breaking down storage tissue (wood). Formation of protective wood in unsealed damaged areas always cause a loss of substance in the storage tissue of the tree, since the tree retreats to a deeper line of defense after being damaged by attack from wood destroyers until an intact protective wood zone has been built up. Layers of protective wood are, however, subject to gradual degradation by knocking and weathering. In healthy trees, however, the degradation of the protective wood layer is less than the new growth or is in equilibrium, so that the existence of the tree is ensured until there is no weakening of growth. For this reason, old and weak trees need to be sealed with existing layers of protective wood.
  • a damaged surface or cut surface worked out except for healthy wood or up to the existing protective wood areas, which are sealed using tree varnish, effectively protect the tree against renewed invasion or degradation in the treated wound area, until the damaged surfaces are formed by callus formation are securely closed again.
