Typical Apple Tree Illnesses
Hawthorns, apple trees, and other members of the rose family are all prone to various ailments. The good news is that these conditions can frequently be avoided, and even when they cannot, they frequently only result in cosmetic harm. Small-scale producers frequently have higher tolerance levels than large-scale growers since their fruit must look excellent to be marketed. But large-scale growers frequently have to use fungicides, which have varying degrees of efficiency. Because spraying schedules might be tricky if you do decide to employ a fungicidal treatment, consult your local county extension office first. You can avoid some of these fungal infections by choosing the right plants in addition to maintaining excellent garden cleanliness, such as clearing away fallen leaves in the fall. Here are some common apple trees diseases according to experts in tree service.
Powdery Mildew
This widespread disease of apple trees is brought on by the fungus Podosphaera leucotricha. Because powdery mildew affects well-known ornamental plants like garden phlox, even those who have never cultivated apples are likely familiar with this disease (Phlox paniculata). Although it’s rare to do so, it will weaken your plant. As its name suggests, powdery mildew is easily identified by the whitish powder that covers the foliage of many of your garden plants.
Apple Scab
The fungus responsible for apple scab is Venturia inaequalis. In the early to mid-spring, you’ll see the first indication of apple scab as a lesion on the tree’s fresh leaves. The lesion will be darker than the color of the leaf; lesions on the leaf’s underside, which is light green, will be olive in hue, while lesions on the leaf’s top, which is a darker green, will be black. In the summer, diseased leaves could completely drop off. Apples with black, scabby blemishes will also be produced if the tree is still able to bear fruit. Fortunately, the apples are frequently still edible. Simply remove the skin before eating.
