How To Get Rid Of Aphids On My Peach Tree
If you want to take the job into your own hands, try hosing your tree down. A strong gust of water knocks aphids right off, and once they fall, its not likely theyll find their way back.
This blog post includes additional tips and information on how to get rid of aphids on large and tall trees, but the tips laid out here apply to any size tree!
What Is Eating My Peach Tree
Aphids are common plant pests that can destroy leaves of peach trees. Peach twig borers, peachtree borers and shothole borers do considerable damage to trees and their fruit. Nematodes are wormlike pests that attack the roots of peach trees, and green fruitworms are caterpillars that attack leaves and fruit.
What can I put on my peach tree for bugs?
Apply Spinosad, a natural bacterial insecticide, if caterpillars or peach twig borers are a problem. After most petals have dropped: Spray peach trees with a copper fungicide, or use a combination spray that controls both pests and diseases.
Why does my peach tree have holes in the leaves?
Peach shot hole, sometimes also called coryneum blight, is caused by a fungus called Wilsonomyces carpophilus. The most common symptoms of peach shot hole fungus are lesions on the twigs, buds, and leaves. These lesions start out as small, dark purple spots.
How Powdery Mildew Spreads
Almost all types of mildew spores are spread by the wind in warm, dry weather. They do not disperse easily when the conditions are rainy and cool. Some mold spores are specialized for certain groups of plants and wont spread to different plant families.
Some spores also overwinter if they are present in leaf piles or other garden debris. Try to discard these piles toward the end of the fall. Do not put the debris from infected plants into your compost bin.

When Conditions Are Ripe
T. deformans is picky. It can only operate during wet weather that has lasted at least 12.5 hours. Two days of wet weather is better still. The temperature must be below 61F but above 47F. The bud-conidia can only bud when the air is humid . When the temperature becomes 69F, the division stops, and the tree is protected from symptoms of peach leaf curl even if it has fungus on it. Cool-weather favors the fungus as it has longer to reproduce, and the trees development slows down. Hot, dry weather with temperatures of 79-87F stop the fungus from developing further.

What Causes Peach Tree Leaves To Curl
Thats caused by peach leaf curl. Its a fungal disease that targets trees during the growing season. A cool, wet spring day is the perfect environment for the fungus to spread and infect a tree.
Initial symptoms of this disease include peach tree leaves turning red, puckering up and curling. As the spring season goes on, this disease causes leaves to turn yellow and fall off early.
Phytophthora Root Rot And Crown Rot
Soil pathogens in the genus Phytophthora can cause crown and root rot diseases of almost all fruit and nut trees, as well as most ornamental trees and shrubs. This disease appears if the soil around the base of the tree remains wet for prolonged periods, or when the tree is planted too deeply.
Symptoms: Infected trees often wilt and die quick as soon as the weather warms up. Leaves may turn dull green, yellow, or even red or purplish. Symptoms may develop first on one branch then spread to the rest of the tree. Dark areas appear in the bark around the crown and upper roots. Gummy sap may ooze from the diseased trunk. Reddish-brown areas may show between the bark and wood.
Control: ManualGood water management/drainage is the key to prevention. Never cover the graft union with soil and try to avoid direct watering of the crown. If you suspect crown rot, carefully cut away affected bark at the soil line. Trees can sometimes be saved by removing soil from the base of the tree down to the upper roots and allowing the crown tissue to dry out.

How To Get Rid Of Tree Fungus
If you have trees and shrubs around your home or in your backyard, you know how unsightly it can be to have fungus growing out of them. Not only is tree fungus hideous, but it can also damage trees and shrugs by breaking apart their structural integrity and attracting additional pests. This can actually be quite dangerous, and well explain why.
In short, tree fungus is something you should try to get rid of, or prevent, if at all possible.
Whether it is powdery mildew, oak bracket, black spot, verticullum wilt or any number of other tree fungi, there are a few things you can do about it.
Phytophthora Root & Crown Rot
Root and crown rots are very important diseases that affect stone fruits. Trees often die within weeks or months of the first symptoms, but in other cases, the decline is gradual, occurring over several growing seasons. The disease is caused by fungi in the genus Phytophthora, and is most severe in areas of poor drainage.
Infected trees have stunted shoot growth and leaves become sparse, small, and yellow. Fruit will be small and sunburned. Shoot and scaffold limb dieback occurs as the disease progresses. Crown rot symptoms appear as black decayed areas on the root crown and or trunk base near the soil line. Cankers that exude a gummy resin are often present. Root rot symptoms include few feeder roots being present, with the remaining roots often decayed.
Prevention & Treatment: There is no chemical control available for crown and root rot in the home garden. The most important control strategy is careful water management. Try to plant your trees shallow, maybe even shallow, on a 6 to 10 raised bed. Do not overwater trees. Select well-drained sites for planting, and improve drainage of the existing location.

Keeping Peach Trees Healthy Against Fungal Diseases
Plant trees in fertile, well-drained soil in a location with plenty of direct sun. Avoid areas where another peach or related tree has recently grown. These planting conditions help prevent fungal diseases from starting in a tree.
Fertilize the tree each year with an application of high-quality compost, aged manure, or a fertilizer mix. A vigorously growing, healthy tree is more resistant to fungal disease problems.
Cut-out diseased wood any time you find it, and prune the trees each year to keep them growing vigorously and fruiting. Keep trees from becoming stressed by watering them thoroughly on a regular schedule during warm weather.
Use A Fungicide Designed For Use On Trees And Shrubs
A good fungicide can do wonders on tree fungus. Just make sure it is designed for use in the landscape, on trees and shrubs.
The product we like is Natria Fungicide which seems to work on nearly any kind of outdoor fungus. Apple tree rust, regular leaf fungus, even lawn fungus. We also know from personal experience that it is quite effective on powdery mildew, the annoying affliction that likes to target popular magnolia trees.
It comes in either concentrate or an easy spray bottle. Just make sure you apply it when it is cool on a not-so-hot day or in the evening. Applying during a very hot and sunny day could cause it to burn the plant or tree it is being applied to. You also need to really saturate the tree bark, in order for it to work correctly.

Peach Leaf Curl Disease
This disease is caused by the fungus Taphrina deformans. It is a very tricky disease that in heavy infestations can cause serious defoliation, fruit deformities and loss of tree vigor. Fortunately, in most cases, you will likely only see small amounts of this disease that disappear as we reach the high temperatures of summer.

Peach curl forms as a bubble fungus on peach tree leaves.
Eventually, these infected leaves will turn brown and drop off. For many, this will be as bad as it gets.
However, some peach trees are more susceptible. In those cases, the symptoms may persist on the tree for a month or more, spreading to more leaves and even infecting the fruits with the same red and bumpy rash. Those severe infections will require treatment. The only bad news is that by the time symptoms appear, it is absolutely too late to do anything about it.
Peach leaf curl can only be mildly treated with a copper fungicide spray in fall after the leaves drop, or in very early spring before bud break . Even with the sprays, it is a tricky disease and it is very normal to still see some symptoms after treatment. So even though it is too late to spray for this season, now you can be prepared to take care of it for next season.
