Common Peach Diseases: How to Identify and Treat Them

As a fruit tree grower, it's important to be aware of the different diseases that can affect your trees. One of the most popular fruits in the world is peaches, and with popularity comes a higher risk of disease. In this article, we'll talk about common peach diseases, how to identify them, and what to do if you find them in your orchard.

1. Brown Rot

Brown rot is a fungal disease that affects peach trees during periods of high humidity and warm temperatures. Symptoms include brown spots on the fruit, shriveling, and a sweet, sour smell. It's important to catch brown rot early because it can spread quickly and ruin entire crops. To prevent brown rot, make sure to keep your tree pruned and remove any damaged or diseased fruit immediately.

2. Peach Leaf Curl

Peach leaf curl is a fungal disease that causes leaves to become distorted and discolored. The leaves may turn yellow, red, or purple and eventually fall off. This disease is caused by spores that overwinter on the tree, so it's important to spray with fungicide in late winter or early spring before buds break. If you notice symptoms of peach leaf curl, remove infected leaves and dispose of them properly to prevent the disease from spreading.

3. Bacterial Spot

Bacterial spot is a bacterial disease that causes dark spots on leaves and fruit. These spots can also become sunken and have a yellow halo around them. Bacterial spot thrives in warm, wet conditions and can spread rapidly through an orchard. To control bacterial spot, practice good sanitation and avoid overhead watering. Copper fungicides may also be used to prevent the spread of the disease.

Powdery mildew is a fungal disease that can affect many fruit trees, including peaches. Symptoms include a white, powdery coating on leaves and fruit. Powdery mildew thrives in humid conditions and can spread quickly. To prevent powdery mildew, avoid overhead watering and prune your tree to improve air circulation. Fungicides may also be used to prevent the spread of the disease.

Shot hole disease is a fungal disease that causes small, circular lesions on leaves and fruit that look like bullet holes. The lesions can later enlarge and merge together, causing leaves to drop prematurely. To prevent shot hole disease, practice good sanitation and avoid overhead watering. Fungicides may also be used to prevent the spread of the disease.
