Q.Problem With Leaf Curl On An Apple Tree

Zone Bognor Regis, West Sussex, PO22 7RA | John Symonds added on June 17, 2020 | Answered

I have an apple tree which is approx 5 years old. It bears poor fruit and some years none at all. I have noticed ants running up and down and regularly use bug spray and ant killer (that is the white powder shown in the photos). There is also a white fluffy fungus which appears regularly (photo attached)and seems to contain some small black/brown eggs or seeds (don’t know). I regularly brush this off and spray with bug spray. The leaves often appear curled and sometimes black/brown. Various photos attached. I have submitted a similar question about my pear tree which is about 3m away and is similarly affected but no ants or white fungus on that one. Please note. I am aware that leaf curl can be associated with underwatering. Both trees get plenty of water so I do not think that is the problem. Can you please give me some advice on how to proceed. regards John R. Symonds email: john.symonds2603@btinternet.com

This is another fungal infection. Peach curl will not transfer to apples, but all of these diseases have one main thing in common: Saturated soils.

The most common cause for infection ridden soils will be overwatering. This leaves the soil lacking oxygen, and acidic, making it the perfect breeding grounds for all of the bad infections that you are seeing on your trees.

From here, I would have your soil professionally treated. Your local agricultural services can help.

This is a widespread issue that will need to be addressed by a qualified professional. This is something that you don't want creeping outside of containment, as it can start to infect widespread portions of land.
