Euonymus-Skala

Weinender oder kriechender Euonymus wird aufgrund der starken Euonymusskala selten als Bodendecker empfohlen.

Die Pflanzen entwickeln auf den Stängeln und Blättern auf den Ober- und Unterseiten ein weissliches Wachstum. Blätter werden fleckig und werden gelb.

Infizierte Pflanzen sind schwer zu kontrollieren. Pflanzen können im Frühjahr (März) mit einem Gartenbauöl besprüht werden. Hausbesitzer sollten gewarnt werden, dass der Ölspray die Pflanze zum Entblättern bringt. Stämme und Blätter können auch entfernt und kompostiert werden. Neues Wachstum kann glücklich sein und nicht befallen werden.

Insektizidsprays können angewendet werden, wenn sich die Scale-Crawler aktiv bewegen und ihre Hüllen nicht erstellt haben. Dieser Zeitraum tritt normalerweise im Juni auf, wenn Sommerrosen (Chionanthus), Weißdorn (Crataeus crusgalli), Schönbusch (Kolkwitzia) und Spätblättrige (Syringa villosa) in voller Blüte stehen.
