Title: What causes peach fruit to ooze sap?
Answered by: Joe Marcus
Peach, Prunus persica, is a non-native species and is outside our area of expertise. However, we may be able to help some. The culprit is likely Stinkbug, but other insects including Peach twig borer, Plum curculio, and Green June beetle are all possibilities. A fungal disease is less likely based on your description of the problem.
You should first contact your county's Cooperative Extension Service agent to find out how to positively identify the cause of the damage to your fruit. When you have determined the ID of the pest, your extension agent will be able to make recommendations about how to protect your crop.
