Plum aphids

And that is particularly true for powdery mildew of apples and crabapples, Podosphaera leucotricha. The apple powdery mildew attacks both cultivated and wild apples and crabapples. And it occurs in the all regions of the world that produce apples! Powdery mildews get their name from the white spores that are produced by the mycelia fungal threads.

The disease on apples attacks virtually every stage of the plant — buds, blossoms, new shoots, leaves, and fruit. We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.While fungicides are the standard treatments, there are some cultural practices that can help control this disease.

Unlike most fungal infections, apple powdery mildew spores do not require moisture to germinate. If your tree is infected, the first thing you will notice is a delay of up to four days in the opening of the infected buds in the spring. These buds are covered with spores. Next, the leaves and blossoms become covered with the fungal spores as they emerge from their buds.

The spores look like a light gray or white powder, and the infected leaves curl upward. These spores are easily blown by the wind and cause secondary infections on new shoots, leaves, and fruit.

While this sounds really high, it is common on the lower leaf surface. The disease on the leaves occurs first on the bottoms and may appear like chlorotic spots on the top of the leaves.

As time passes, the tissues that are infected develop the classic silver-gray powdery mildew appearance. Fruit that is infected will come down with discoloration and netlike reddish brown colors. High levels of powdery mildew at the end of the growing season can damage the tree in two ways. First, it can increase the number of infected buds, so you will have a high level of infection next spring.

And second, it can inhibit the formation of flower buds, so that there will be fewer or no fruit produced the following season. Avoid the excessive use of fertilizer, especially in the late summer. This will prevent succulent new tissue from growing, which is easily infected by the fungus.

Another thing you can do to protect your tree is to plant it in a sunny area, since excessive shade, high humidity, and poor circulation all increase the chances of infection. Since this is such a difficult disease to control, and it is critical to eliminate the spores that will keep infecting your tree, you may choose to apply fungicides.

Be sure and choose ones that are labeled specifically for fruit trees.You have a choice of low toxicity fungicides like horticultural oils. These include jojoba oil, neem oil, and brand name spray oils designed for fruit trees.

Classic fungicides that are used against apple scab, such as sterol inhibitors, are highly effective at controlling powdery mildew. These include myclobutanil and fenbuconazole.

Since the fungus overwinters inside buds, you should start treating your tree early in the season before the blossoms start to show a pinkish color. The failure to spray before the blooms opens is one of the most common mistakes made in controlling this disease according to the American Phytopathological Society.

Be sure and repeat the sprays at week intervals until the new shoots stop growing. That could mean as many as 18 sprays if your cultivar is highly susceptible!

Also be sure to continue spraying even if the weather becomes dry. Unlike most other foliar pathogens, apple powdery mildew continues its growth and spore production in dry weather. Be careful with sulfur. You can harm the plant if you apply it within two weeks of a fungicide or if the temperatures are greater than 90 F. This class of fungicides includes the classic Bordeaux mixture of copper sulfate and lime.

This combination is highly effective at preventing powdery mildew and is certified organic. You can buy a pre-packaged mixture designed for small gardens. The ultimate prevention technique is to plant resistant varieties!

Some of the most popular cultivars are the most susceptible — Granny Smith, Jonathan, and Rome for example. Although apple powdery mildew will not technically kill your crop, it can debilitate the tree to such an extent that it could be unable to produce any fruit. This disease is widespread on wild and cultivated apples and crabapples in every part of the world in which they are grown.

Therefore, it is critical to know the symptoms of this mildew, so you can be ready to take action as soon as you see infected tissue.You will need to spray with some sort of fungicide — sulfur, horticultural oils, or sterol inhibiting fungicides.

A strict spray schedule may help save your tree from this aggressive pathogen. Have you successfully fought off powdery mildew on your apple or crabapple tree?
