Best Fungicide For Shot Hole Disease
Introduction
Shot hole disease can cause damage to the leaves of trees, causing brown, circular spots with yellow halos around the edges. It can also affect the fruit and branches, causing small red to black spots that grow as large as two inches in diameter. The fungus responsible is Stigmina carpophila and spreads via spores produced in the leaf lesions that are spread by wind and water but not by insects. Affected leaves drop prematurely mid-summer, and those that survive harden and become covered with raised, black pustules. Pest control specialists have developed a fungicide for use against shot hole disease.

Shot hole disease is a fungal disease that primarily attacks the leaves of trees, causing brown, circular spots with yellow halos around the edges. The fungus can also cause red to black spots on the fruit and branches. It is caused by a fungus called Stigmina carpophila.
Shot hole disease affects a wide range of trees including ornamental plants such as azaleas and rhododendrons, fruit trees like apples and pears, large shade trees like maples, oaks and elms as well as many other broad-leaved deciduous trees.
It can also cause red to black spots on the fruit and branches.
- It can also cause red to black spots on the fruit and branches.
- Fruit spots are caused by the fungus, and they’re usually round or oval in shape, with a red or orange center surrounded by purple/black margins.
- Fungicide treatment is necessary to prevent further damage—and even if you do treat for shot hole disease, your tree may still have some lingering symptoms of this disease after treatment.
In some circumstances these can grow as large as two inches in diameter.
- In some circumstances these can grow as large as two inches in diameter.
- The spots on the leaves are usually about one centimeter in size, but can vary from half a centimeter to three-quarters of an inch.
- The spot is larger than the leaf and further into the leaf that it produces a blemish or distortion of the foliage.
The disease is caused by a fungus called Stigmina carpophila.
The disease is caused by a fungus called Stigmina carpophila. This fungus is a common pathogen of fruit trees and is most active when the relative humidity (RH) is high, usually above 80%. The fungus reproduces by releasing spores in the air which can be spread to other plants through wind or rain. It also spreads through grafting, pruning tools, and even insects like bees that feed on pollen from infected flowers.
The disease can be found wherever there are apple trees growing in areas with cool wet weather such as British Columbia or Washington State where it was first discovered over 100 years ago but has only recently started appearing in California orchards where growers have been using fungicides for decades.
This fungus spreads via spores produced in the leaf lesions that are spread by wind and water, but not by insects.
Shot hole disease can be spread by spores produced in the leaf lesions that are spread by wind and water, but not by insects. Spores can also be spread by people, animals, or any moving thing that comes in contact with them.

Affected leaves drop prematurely mid-summer, and those that survive harden and become covered with raised, black pustules.
Fungal spores infect the plant through wounds or stomata, infecting new leaves and shoots in early spring. Affected leaves drop prematurely mid-summer, and those that survive harden and become covered with raised, black pustules. The presence of this fungus can be reduced by pruning affected leaves at least once a year during the first three years after planting. This will decrease your plant’s susceptibility to infection by reducing leaf surface area.
If you have already noticed symptoms of shot hole disease on your trees but want to prevent its spread further into your landscape—or if you simply want to get rid of it—it may be necessary to destroy infected plants as well as surrounding ones that are close enough for spores from each other’s leaves to reach via wind or water movement (which is why it is important not only remove infected plants but also remove any dead wood lying under them).
Pruning and destruction of fallen leaves helps reduce the spread of this disease.
In order to reduce the spread of shot hole disease, you should prune and destroy fallen leaves. Other important steps include keeping your trees well-watered and fertilized, as well as spraying trees with a systemic fungicide. You can also use a preventive fungicide if you have an outbreak of this disease. If possible, apply it early in the season so that it has time to work its magic before summer gets here or if it’s already here, reapply every 7-14 days to keep up with growth spurts during warm weather.

It can also cause red to black spots on the fruit and branches. In some circumstances these can grow as large as two inches in diameter. The disease is caused by a fungus called Stigmina carpophila
