Leaf curl can be controlled by applying sulfur or copper-based fungicides that are labeled for use on peaches and nectarines. Spray the entire tree after 90% of the leaves have dropped in the fall and again in the early spring, just before the buds open.
How do you fix a curled peach tree leaf?
To control Peach Leaf Curl, treat Peach and Nectarine trees with a fungicide in the fall after leaves have dropped. In the past, the disease could be successfully treated with either lime-sulfur fungicide or a fixed copper fungicide with a copper compound containing at least 50 percent copper.
Should I remove curled peach leaves?
Remove the puckered leaves as they curl and keep them from piling up under the tree and releasing spores that will further infect the tree and its neighbors. Thinning the baby fruit to one fruit every five to seven inches will allow the tree to maintain its strength.
What is the best fungicide for peach leaf curl?
Peach leaf curl is not difficult to control. A single fungicide (copper or chlorothalonil) application made in the fall after leaves have dropped or in spring before bud swell will control the disease.
What causes curly leaf in peaches?
Peach leaf curl is mainly a disease of peaches and nectarines, though it may also affect almonds and apricots. It’s caused by the fungus Taphrina deformans and occurs wherever peaches and nectarines are grown. If not controlled, it can seriously weaken trees.
Can leaf curl be reversed?
Yellow leaf-curl virus, transmitted by whiteflies, prompts leaves to curl up and turn pale green. You cannot treat or cure infected plants, and they likely will not recover. Remove the plants from the garden and dispose of them.
Does peach leaf curl damage fruit?
Infected leaves become thick and curled with red and yellow discolouration. Infected leaves eventually drop. Heavy leaf infection and defoliation may reduce crop and tree vigour. Fruit may also be infected, although this is much less common.
Can peach leaf curl spread to other trees?
The fungus causes the growing cells at the leaf margins to multiply quickly and randomly which results in the curled and distorted appearance. The fungus then wastes no time producing spores on the surface of the leaf that spread to other leaves and fruits on your tree or other trees in the area.
Can you save a peach tree with leaf curl?
Leaf curl can be controlled by applying sulfur or copper-based fungicides that are labeled for use on peaches and nectarines. Spray the entire tree after 90% of the leaves have dropped in the fall and again in the early spring, just before the buds open.
Should I cut off curling leaves?
If curled leaves do persist, though, you’re better off removing them so your plant can conserve its energy for the healthy leaves.
Does overwatering cause leaf curl?
Overwatering
Too much water can cause root rot and lead to the leaves curling upwards. To avoid this, water sparingly and always allow the top couple of inches of soil to dry out completely before adding water.
What kills curly leaf on fruit trees?
A number of things, but two of the most important ones are: Before the tree buds swell, spray it with lime sulphar. The fungi absorb the sulphur and it stops them from being able to create energy.
What do you spray on peach trees for fungus?
Use fungicides with propiconazole or captan (make sure they’re safe for peach trees). Start spraying at full bloom and repeat twice at 10- to 14-day intervals. Once your peaches begin to change color, start spraying every seven days. You also can use Clemson Fruit Bags to prevent infection.
When Should I spray my peach tree for leaf curl?
The best time is after leaves have fallen, usually in late November or December, but in wet climates or during a wet winter, a pesticide application can be made in late winter (January or February) just before or as buds swell.
What do curling leaves indicate?
When leaves curl or ‘cup’ at the tips and the margins, the plant is trying to retain moisture. Any form of downwards curling usually indicates overwatering or overfeeding.
What deficiency causes curling of leaves?
Calcium (Ca)
Calcium is needed by plants to produce new growing points and root tips. Deficiency symptoms: New foliage, buds and roots have stunted growth. Younger leaves curl downwards with browning of leaf edges and leaf tips, also known as tip burn.
Should I remove curled leaves?
In most cases, they’re not. Once you identify the culprit causing the curling, you should be able to get your plant back to normal relatively quickly. If curled leaves do persist, though, you’re better off removing them so your plant can conserve its energy for the healthy leaves.

How do you treat peach leaf curls in the summer?
Remove any infected leaves as soon as they are seen, together with flowers and fruit. Clear up infected, fallen leaves around trees. Cover fence or wall-trained trees with polythene sheet in January and February to prevent development of fungus. Alternatively, erect an open-sided ‘tent’ over bushes in the open garden.
