Signs of damage
- Spots on the leaves. Despite the whole three being affected, stems, buds, and fruits included, the leaves’ light green or yellow spots are a most telling sign.
- Shot holes. These brownish spots then drop out, leaving the holes.
- Spots on fruits. At first, they are tiny and purple, but later they turn white or gray.
- Gummosis. The process is when a gummy substance is created on affected plants, and sometimes it happens due to Shot Hole Disease.
How to prevent
Improve the conditions in which the plant is growing because the excellent health makes the three more resistant to the various diseases. And you can make your life easier by buying a variety that is more immune to the Shot Hole Disease.
In this case, fungicide will be helpful. But you need to improve the health of the damaged plant, so it’s better to combine using fungicides with additional tree care. And this also will guarantee that the disease will be less likely to appear again.
Pruning of the three is also a good idea. Pruning helps to establish proper air circulation, which makes the tree healthier. And during this process, you will cut the affected leaves or branches, which also minimizes the chances of diseases reappearing.
