Hello,

The clear jelly-like substance leaking from your peach tree is a symptom known as gummosis. This condition can be caused by various factors, including chemical, physical, insect, disease, or stress damage to the trunk and branches. More information at these links:

Here are some potential causes and treatments:

Insect Damage: To rule out peach borers, check for boreholes and frass (insect waste) beneath the sap. More information at this link:

Water Damage: Ensure that irrigation systems do not wet the trunk and that weeds around the trunk are controlled. More information at this link:

Physical Damage: Wind and other physical stress can cause gummosis. This may not be a significant issue if the tree is otherwise healthy. More information at this link:

Fungal Infection: Fungal pathogens like Botryosphaeria can infect wounds or lenticels on the tree, leading to cankers that ooze sap. More information at this link:

Treatment generally involves reducing stress on the tree and practicing good sanitation. This includes removing and destroying diseased wood, avoiding pruning when the tree is wet or stressed, and ensuring proper irrigation practices. Fungicide applications to the trunks of young trees may help suppress fungal infections. More information at this link:

Identifying and treating the specific pest is crucial for insect-related gummosis. If you suspect a fungal cause, removing the affected areas and applying fungicide may be necessary. It’s always a good idea to consult with the MSU Plant and Pest Diagnosis office or a professional arborist for a precise diagnosis and treatment plan.

OPTION 1:

MSU Plant & Pest Diagnostics Lab WILL NEED an image of the peach tree's trunk that shows the leakage I asked for earlier.

For a confirmed and precise identification of the problem, I recommend you send all your images by e-mail to the MSU Plant & Pest Diagnostics Lab. The experts there can also provide you with the best treatment options. Their email is <personal data hidden>. Please include your name. The lab will let you know if they need a sample sent. FYI, the lab may also ask for additional images.

Maintaining overall tree health through proper care and management is the best way to prevent gummosis and other issues.

I hope this helps!
