Common Diseases for Apple Trees

What is Apple Scab?

  • Apple scab is a fungal disease affecting apple trees that causes olive-green to black spots on the fruit and leaves. When the leaves are infected they become dwarfed, curled and drop prematurely. This leaf loss, especially when it happens over many seasons, can significantly weaken the tree. If the fruits get infected in the early season, they can get deformed and drop early in June. Moreover, unlike apples affected by sooty blotch, you usually can’t eat scabby apples.
  • Causes: During the winter, apple scab can survive in the dead apple leaves on the ground. Then in the spring, these fungi shoot spores into the air which the wind carries to the growing leaves, flowers, and fruit. In order to start new infections, the spores have to have a couple hours of moisture. Afterwards, the infections grow into spots which produce more spores.
  • Recommendations:
    • Firstly, you can choose scab resistant varieties such as Freedom, Liberty, Prima, Jonafree, GoldRush, and MacFree.
    • Secondly, remove fallen leaves from under the tree. If you control it in the early season it will be much easier to control in the summer.
    • Spraying is also an option.
Identifying Pests and Diseases

What is Powdery Mildew?

  • Powdery mildew affects all fruit trees and is a fungal disease that shows up on the leaves of trees as white, powdery mold.
  • Causes: The fungi overwinter in the dormant buds. Then during the spring, they spread onto the flowers, leaves, and fruit. This fungi doesn’t overwinter in pear tree buds. However pear trees can get the fungi from nearby apple trees. Moreover, really cold winter temperatures can kill the infected buds since they are more susceptible to winter injury than healthy buds. The infection which will cause the fruit to russet can occur from about 3 weeks before bloom to 3 weeks after bloom.
  • Recommendations:
    • Firstly, plant and prune in a way so that the trees and branches aren’t overcrowded. Then prune out the areas and branches with white fungus.
    • If you know that powdery mildew occurs in your area, then do not plant susceptible apple varieties such as Idared, Monroe, Rome Beauty, Jonathan, Paulared, Gingergold, or Cortland.

What is Fireblight?

  • Fireblight affects mostly apple and pear trees, in addition to some other fruit trees. The tree’s branches will not only blacken but also droop rapidly as if scorched by fire (hence the name fireblight). Additionally, the bark at the base of infected twigs will become water soaked, then dark, sunken and dry, with cracks developing at the edge of the sunken area. Other signs include wilted shoots, well-defined areas of burnt-looking, dead foliage or bark, and sticky amber ooze.
  • Causes: The damage mostly happens during warm, rainy spring weather. Fireblight bacteria overwinter between live bark tissue and the tissue killed the previous season. Additionally, the bacteria can enter through openings such as flowers and wounds in the spring. Then rain, wind, and pruning tools can spread the disease to other plants. Finally, in the spring, the bacteria ooze out of the cankers and attract bees and other insects which also spread the disease.
  • Recommendations:
    • Firstly, do not grow your fruit trees on poorly drained, highly acidic, or overfertilized soils.
    • Secondly, if you see infected twigs, cut them off in the early spring at least 8 inches below the damaged area.
    • Additionally, if you prune in the summer, disinfect your pruning tools with denatured alcohol or a 10 percent bleach solution between each cut.
    • Resistant apple varieties include Enterprise, Freedom, Liberty, Prima, Priscilla, Adams, Dolgo, Jewelberry, and Liset. Susceptible apple varieties include Idared, Jonagold, Jonathan, Lodi, Crispin (Mutsu), Greening, Paulared, Rome, Sir Prize, Spigold, Twenty Ounce, York and Gala.

What is Cedar Apple Rust?

  • Cedar apple rust is a disease which leaves red-black spots on the leaves of apple trees and visible spores on their undersides. This disease can cause damage to the leaves and fruit of very susceptible apple varieties, but is only a minor problem on resistant or partially resistant trees.
  • Causes: This disease requires two hosts in order to complete its life cycle, an apple tree and an eastern red cedar tree. In fact, it survives the winter in galls on the cedar trees. Then with the rains in the spring hornlike extrusions emerge and release spores. In fact, with the wind, these spores can travel to nearby apple trees and cause orange spots on the leaves. Then 1-2 months later, the fungi can grow to on the undersides of the leaves and on the fruit. Moreover, the fruit will be infected when it is moist and the temperature ranges between 46 degrees F and 75 degrees F. Afterwards, the spores from the apple trees will be released in the summer and infect the leaves of the cedar trees.
  • Recommendations:
    • Firstly, either remove nearby eastern red cedar and juniper trees within a few hundred yards of the apple trees or do not plant the apple trees nearby.
    • You can plant disease resistant varieties such as Delicious, Liberty, Nova Easygro, Novamac, and Tydeman. However varieties that are susceptible include Golden Delicious, Jonathan, Lodi, Prima, Rome, Twenty Ounce, and York
