Gumosis

Have you seen a little jelly on your peaches?

It’s not nature’s way of tempting you, it’s actually a common bacterial infection that can pose a severe health hazard to your fruit trees!

Gummosis is a condition where peach trees produce gummy sap due to bacterial infection. Fruit trees can get gummosis when they are infected by bacteria through wounds or injuries on the bark (commonly pruning cuts.) The bacteria will enter the tree and cause the sap to become gummy.

The most common bacteria that cause gummosis in peach trees are Pseudomonas syringae and Xanthomonas arboricola. It’s important to research fungicides that will specifically target

Fungicides

Some organic sprays that will help control the infection are sprays with citric acid like Neem oil. Anti microbial sprays like garlic and thyme essential oils.

If you need something stronger try copper based fungicides like Bonide Copper Dust or Arber Bio Fungicide. Copper is a natural antibacterial compound that provides a barrier on the plants surface.

Treatment

If cankers are present on the infected area, it's important to take action. Prune off the affected branches, making sure to cut at least 6 inches below the visible canker. Dispose of the pruned material properly to prevent further spread of the bacteria. After pruning, apply a copper-based fungicide to protect the tree and prevent reinfection. Remember to follow the instructions on the fungicide label for proper application.

If you have an infected canker on the base of the trunk, it's important to take action promptly. Here's what you can do:

1. Start by cleaning the affected area. Use a clean, sharp knife to carefully remove any loose or dead bark around the canker. Make sure to sterilize the knife between cuts to prevent further contamination.

2. After cleaning, apply a copper-based fungicide to the exposed area. This will help to control the bacteria and protect the tree from further infection. Follow the instructions on the fungicide label for proper application.

3. Monitor the tree closely for any signs of worsening infection. If the canker continues to spread or the tree's health deteriorates, it's best to consult with a professional arborist for further guidance and potential treatment options.

Remember, treating an infected canker on the base of the trunk can be challenging, so seeking professional advice is always a good idea to ensure the best course of action for your specific situation.
