If the joy of growing peaches is clouded, one thing is mostly to blame: the curling disease. Here are a few tips to help fight the disease.

Peach frizz

One of the most common diseases of peach trees is the so-called curling disease, which is unfortunately very difficult to control. After all, it not only spreads to peach trees, but also affects apricot and nectarine trees. The cause is a fungus called Taphrina deformans, which even a harsh winter cannot harm.

So once you've caught the mushroom, it means a lot of work to get it away. It is therefore better from the outset to prevent the disease in good time and to take a close look at the peach, apricot and nectarine trees.

Damage of the curling disease

Infestation with the curling disease is usually only visible in the peach trees in April. Once the fungus has nested, the leaves start to curl more and more until they finally curl up and form thickenings. Over time, there are also discolorations, which can be recognized as either white or reddish spots on the leaves and become darker over time. At the beginning of summer, i.e. in June, the leaves are so damaged that they fall completely off the tree.

If you notice discolored, crooked leaves on the peach tree during a gardening season, it may well be that the plant will recover by the next spring. Often, however, the tree will only have a few buds so that the yield can be greatly reduced.

Prevention / control of frizz

❖ Tip 1 - choose the right location:

When planting the trees, you can do something to prevent fungal diseases by choosing a sunny, airy location on your property.

❖ Tip 2 - Regularly level the crown:

It is also good if you regularly thinned the crown, because the thicker it is, the worse it dries after a downpour. And that in turn can promote the spread of curling.

❖ Tip 3 - fertilize peach trees:

From time to time, supply the peach trees with a mineral or organic long-term fertilizer, so that they become nicely resistant. For strengthening you can also spray the trees with a field horsetail tea regularly. Recommended reading: Field horsetail: tips for cultivation and use.

❖ Tip 4 - planting peach trees:

To prevent this, planting the peach trees with nasturtiums, horseradish or garlic has also proven effective.

❖ Tip 5 - use a biological tonic:

You can get rid of the curling disease particularly well with a biological tonic. For example, the Neudo-Vital fruit-mushroom protection from Neudorff (available here) is recommended.

Since the infection of the leaves occurs very early in the year (as soon as the buds swell), it is advisable to spray the entire tree crown at the end of January with such a means in dry weather. Before doing so, however, it is important that you remove the stunted shoot tips and all fruit mummies and do not dispose of them in the compost but in the household waste. Then spray the tree evenly. Repeat this procedure three to four times every two to three weeks.

❖ Tip 6 - use chemical pesticides:

There is also a chemical plant protection product that is the only one approved for curling. It is Duaxo Universal mushroom-free, which is offered by the company Compo. Duaxo is a broad-spectrum fungicide against a wide variety of fungal diseases in roses, ornamental and woody plants, fresh herbs, fruit and vegetable crops. It stops the curling disease from spreading and protects against new infestation. However, you should really only use it if the other fighting tips have no effect at all.

❖ Tip 7 - Remove leaves and shoot tips:

If the stubborn fungus is found late, all leaves and shoot tips should be removed as quickly as possible so that at least no further spread can take place. Cut the shoots back into the healthy wood and destroy the clippings or dispose of them with household waste.
