Krone Gall

Gallen, die an Wurzeln oder Stängeln von krautigem Material auftreten, werden durch ein bodenbürtiges Bakterium verursacht und Crown Gall genannt. Diese Gallen variieren von der Erbsengröße bis zu einigen Zentimetern im Durchmesser, was das Aussehen eines krebsähnlichen Wachstums ergibt. Pflanzen mit zahlreichen oder großen Kronengallen können ein vermindertes Wachstum, gelbe Blätter oder andere Symptome von allgemeinem Leiden aufweisen. Stark infiziertes Pflanzenmaterial ist anfälliger für Winterschäden. Diese Gallen stören den Wasser- und Nährstofffluss zwischen den Wurzeln und Blättern. Plant Tod kann auftreten.

Vermeiden Sie verwundende Pflanzen während des Umpflanzens, Kultivierens und Mähens. Reinigen Sie die Schnitt-, Knospungs- und Pfropfwerkzeuge zwischen den Schnitten mit frischer flüssiger Haushaltsbleiche. Sorgfältig zu graben und schwer infizierte Pflanzen zu entsorgen. Pflanzen Sie den gleichen Pflanzentyp nicht für mindestens 5 Jahre an derselben Stelle ein.

Häufig betroffene Pflanzen sind Euonymus Wintercreeper, Rosen, Liguster, Rhododendron und viele Nusspflanzen.
