Leaf curl disease is the most dangerous
Overwintered spores of the fungus germinate into shoots and leaves in early spring, overwintering on plant remains of the previous year. The causative agent of leaf curl disease is introduced into the leaf. The first sign is the formation of red blisters on the leaf blade. But if the leaves have already hung on the tree for 2 weeks, the disease is powerless.
The fungus is introduced into the plate 5-8 days old. Leaves collapse and fall to the ground with mature spores. Young branches of fresh or annual growth and their wood are damaged. The buds of this year are deformed, and there will be no harvest next season.
How to Treat Peach Leaf Curl Disease? Immediately! As soon as we saw the first signs - young leaves, still green, began to swell, it is immediately necessary to apply copper-containing fungicides in the recommended dose. In this case, it is necessary to immediately start sanitary pruning, scrapping, pinching the sheets, until the disease has captured the entire crown.
Experts and practitioners say that among the peach varieties, some are more resistant to leaf curl:
- Redhaweng;

How can you deal with curly leaves on a peach with folk remedies? Speed is key in eradicating the disease. There are not many effective drugs. If the disease was discovered at the beginning, you need to manually remove the leaves, cut off the branches on which they were attached, and be sure to burn them.
Dust the tree with a mixture of sulfur powder and fluff lime, spray with 1% colloidal sulfur, but only on a hot day, so that the temperature is above 25 degrees. You can use the drug Biostat. For the second treatment, prepare a 3-day infusion of tobacco dust. You can spray with a mixture of slaked lime and clay slurry, applying it to the leaves after each rain wash or shedding. Practitioners warn that if fresh galls appear, you need to switch to fungicides.
Preventive methods of dealing with peach curl begin in the fall. It was during this period that it is necessary to clean the garden of winter tenants. As soon as the air temperature has dropped to 10-5 degrees, it is time for prevention:
- Inspection and sanitization of the trunk, broken branches.
- Free the trunk circle from all residues, burn the leaves and branches, loosen the soil or lay fresh manure over the entire area, without digging, let there be a crust. This is a top dressing for 3 years.
- In the spring, process the buds with a copper fungicide, and then prune. Then treat with Topsin M, but until the leaves appear.
Spray on young leaves with Champion. In the future, if swelling appears, 10% mullein infusion will cope with them. A deserted garden will be free from diseases within 2-3 years.
This is the answer to the question of how to treat a peach from curly leaves. The scheme is used in private gardens in Ukraine. Systemic treatments allow you to get rid of the main fungal diseases even in warm rainy years.
The basic principles of disease control are the ability to grow a healthy, strong tree. Then it will itself resist diseases and pests. To do this, you need to find a light slope, with a barrier from the northern faith. The peach does not tolerate any shading. He loves fertile soil, regular watering and deep standing groundwater. If there is growth in winter, the tree will wake up. The roots will withstand the winter cold +25 degrees for 3-4 days, and 35-38 degrees - for several hours. Whitewashing the trunks and manure in the near-stem circle will help reduce the risk of frostbite.
