Recognize and treat diseases of the robinia
Actually, the robinia is a very robust deciduous tree. Unfortunately, she also has some pests or diseases that she is not immune to. In this case, the tree needs your support, because with the right knowledge, you can get rid of the parasites quickly. The prerequisite is, of course, the earliest possible recognition. That is why we present the three most common diseases of the robinia here.
Common diseases of the robinia
Among the three most common diseases that occur specifically on the robinia count
The Robinia Minier Moth
The pest brought from America has no natural predators here in Germany. The butterfly lays its eggs on the leaves of the robinia. Subsequently, the hatched larvae feed on the foliage. Accordingly, meandering food marks are visible on the leaves. Fortunately, the moth does not endanger the health of the robinia. An intervention is therefore not required. If you still optically disturb the tracks, simply collect the caterpillars from the leaves.
The phloespora leaf spot disease
This is a fungus that spreads particularly often on Robinia. Especially after rainy springs his appearance is likely. Characteristic are centimeter-sized, round spots on the leaves or on the shoots of the petioles. During the year, the shape of the leaves changes, their edges are often torn. Although this pest may not necessarily threaten the existence of your Robinia, you should not stand idly by in the case of Phloespora leaf spot disease. Remove all affected branches with a vigorous pruning. Only when there is no improvement then you should think about the use of chemical agents.
aphids
Although aphids do not occur exclusively on the robinia, but obviously like the deciduous tree. With early detection, the simple spraying helps with a water hose. Even better effect achieves soap soap dissolved in water. Even oil-tinctures bring success in the fight against the parasites. The most natural treatment is to put predators such as wasps or flies on the robinia. However, the chances of success here are not one hundred percent.
