Best Fungicide For Cherry Trees

Cherry trees are susceptible to several different types of fungal infections, including black spots, which can cause leaves to become black and die; Sclerotinia blight, which causes red or pink streaks on the leaves; and anthracnose, which causes orange-red spots on the leaves. This fungicide is highly effective against a wide range of fungi and viruses, including powdery mildew, black spot, and downy mildew. In addition to being effective against these fungal threats, it also is effective against bacterial diseases like root rot.

Cherry trees need a fungicide that is available in liquid form, and that can be used in the spring and fall. The fungicide should be applied to the soil around the tree, as well as to the trunk of the tree itself. It’s best to use a fungicide that has been approved by your local county cooperative extension office and will not harm any other plants or animals. Make sure that you follow all directions on the label.

It’s best not to use a fungicide more than once every two years because it can encourage fungus growth in some cases. If you have a lot of trees in your yard and want them all treated at once, it’s better to invest in an organic fungicide that won’t harm your plants in any way.

Best Fungicide For Cherry Trees

If you have a cherry tree, you probably have wondered what the best fungicide for this species is. In this article, we will go over the pros and cons of the four most common fungicides, Fenbuconazole, Captan, and Chlorothalonil. While they are all good choices, you should still do your research to find the most effective solution for your cherry tree.


The only fungicide available for the control of post-harvest leaf spots on cherries is chlorothalonil. It can be used pre-shuck or after shuck split to prevent cherry leaf spots and reduce the need for additional treatments with other at-risk materials. Using chlorothalonil is safe and effective, and it is available in the market under many trade names.

Chlorothalonil DF is the most effective fungicide for controlling leaf spots on cherry trees. It can be applied to large areas at a rate of one to 2.5 pounds per acre. It can also be mixed with insecticide and applied as a surface spray. It is a fungicide that helps control various diseases, including powdery mildew and brown rot. Chlorothalonil is labeled for cherry trees in Michigan.

This fungus produces spores, which are small seed-like structures that can easily be carried by the wind and rain. These spores are present on the leaves, branches, and fruit of infected trees. During the spring, the fungus overwinters on these infected tissues and releases its spores. When the leaves, twigs, and fruits are spotted with the disease, they have become soft and shriveled and can not be eaten.

If the problem persists after the shuck split, then the best fungicide to apply is Chlorothalonil, which has a broad spectrum of activity. Chlorothalonil is also safe for cherry leaf spots, but it is important to apply it in two applications before the shuck splits. You must also ensure that you use it under certain label conditions if you want to avoid resistance to it.


The most important aspect of fungicide management for cherry trees is timing. Fungicide applications can be more effective early in the season. As cherry leaf spot is a persistent and prolific disease, it is best to start application programs at petal fall and continue every seven to ten days until harvest, with one or two postharvest treatments following. In addition to using fungicides on the trunk branches, growers should alternate the spraying schedule by spraying one side of each tree every seven days and the other side on a 10-day schedule.

To determine whether fenbuconazole is the best e-label fungicide for cherry trees, look for the DMI fungicide label. DMI fungicides are effective in controlling brown rot in cherry trees, but they do not show good control of other fungi. However, fenbuconazole and propiconazole can be used in combination.

The emergence of cherry leaf spots is a common problem in a cherry orchard. The disease begins as small, purple spots on the leaf in early spring, and then develops into large irregular patches. In some cases, the fungus will cause a tree to lose a large number of leaves and blossoms. During these times, it will store carbohydrates in its roots.

Moran is a water-soluble encapsulated methyl parathion (WP). It is effective against mites on fruit trees, but its broad-spectrum action means it cannot be used during bloom. Besides, it may also be applied to nonbearing trees. However, this fungicide is extremely toxic to bees and is not recommended for use near fruit trees.


Myclobutanil is a general-use fungicide that can effectively control many types of fungal diseases, including powdery mildew, fire blight, and peach leaf curl. It is available in several formulations, including ready-to-use sprays, dry flowable formulas, and granular dust. Its effectiveness varies from crop to crop, so it’s important to understand the symptoms of each disease and how to prevent further damage.

Myclobutanil is the best fungicide for cherry trees, as it controls many fungal diseases, including leaf spot and brown rot. These diseases are caused by fungi called Monilinia fructicola and are the most damaging in New England. They cause bloom blights, twig cankers, and fruit rots. When left untreated, cherry trees will suffer a lack of bloom and a decline in leaf color.

In addition to Myclobutanil, other fungicides can be used to control fungal diseases. General-purpose tree fruit sprays are available under several trade names and are effective against several common insect pests and diseases. Typically, they contain the fungicide captan as well as malathion, carbaryl, and methoxychlor. Captan can result in leaf injury on sweet cherry trees and can only be used before the tree has been shuck-split.

The table below summarizes general information about fungicides for tree fruit crops. The fungicides are listed by their common names and the pests for which they’ve registered. They also include a signal word so you can select the best option for your particular situation. If you’re not sure which product to use, refer to the label or the annual spray guide. These guides will provide details about rates, timing, and application methods.


When it comes to fungicides for cherry trees, Captan has a good track record. It is effective against leaf spots, brown rot, and scab. It is also effective on fruit flies. Captan can be used to prevent the appearance of leaf spots on cherries, which is especially common in new or unprotected trees. However, you must apply the product properly, especially during wet seasons. For best results, apply the fungicide to the entire tree and wait until runoff. You can find the correct fungicide for your particular species and cultivar by consulting the label.

When used on cherry trees, Captan provides effective control of scab, brown rot, and rust on many types of fruit. It is also effective against scab, cherry leaf spot, and tart cherry disease. However, Captan can cause leaf injury if applied close to the fruit on apple trees. It is not suitable for pears. Repeated application of Captan can cause damage to some varieties of sweet cherries.

Proper timing is essential for Captan to be effective. The fungicide should be applied one day before harvest. It should also be applied after blooming. The fungicide should be applied four to five times a year. The fungicide should be applied at the right time so that it can protect developing twigs. To ensure that the treatment works, consult the Spray Guide below.

A fungus known as a black knot is an important threat to cherries. Once infected, the disease will destroy the tree’s limbs and spread the infection to new healthy shoots. Therefore, the best approach for controlling black knots is to cut down infected limbs before bud break. A cut should be made six to eight inches below the affected area. Prunus spp. is vulnerable to black knots, so you must take care to prune the infected tissues before they start growing. Captan is a powerful fungicide, but it may also damage Japanese plums.


General Purpose Mix (GPM) contains fungicides and insecticides for a broad range of agronomic problems, including common tree diseases and insect pests. Typically, these fungicides are carbaryl, captan, methoxychlor, and malathion. Some fungicides, however, have additional ingredients, including lambda-cyhalothrin, boscalid, and malathion.

To avoid the risk of disease, it’s important to understand what types of pests and diseases attack cherry trees in your area. You can find useful information by contacting your local Cooperative Extension or state university. Other sources of information are independent garden centers and growers. Remember to follow the label instructions carefully to avoid over spraying or damaging your trees. You should also read the labels on the products you’re using to avoid inadvertently combining chemicals.

If you’re concerned about the risk of leaf spots on cherries, a good sanitation program is crucial. During winter, the disease survives on fallen leaves. To reduce its impact, you can spray the tree with fungicides. Typically, you should start using a fungicide two weeks after the bloom of your cherry tree, and repeat applications at intervals specified on the label. Fungicides containing captan or myclobutanil can protect the leaves from cherry leaf spots, but it’s important to remember that too much use of fungicides can lead to resistance.

The most common disease in cherries is brown rot caused by the Monilinia fructicola fungus. In New England, it’s the most destructive and is particularly prevalent during wet and humid weather. It can infect the blossoms, twigs, and fruit and can cause a host of other symptoms. In the early stages, the disease presents as small spots and develops into a soft, rotten blob.
