Apple trees, peach trees, nectarine trees, pear trees and cherry trees have cultivars that are resistant to diseases that affect each variety. Although some states don't have problems with fruit tree disease as much as other states, fruit trees with resistance to diseases should be used in home gardens and landscaping.
Apple
Apple growers need to consider apple cultivars that are resistant to fire blight, cedar apple rust and apple scab. Enterprise, Liberty, Williams' Pride and Redfree are resistant to fire blight, cedar apple rust and apple scab. Pristine apple trees are resistant to cedar apple rust and apple scab, but resistance to fire blight is moderate. Pristine and Williams' Pride are resistant to powdery mildew. Trees moderately resistant to powdery mildew include Redfree, Liberty and Enterprise. Apple trees need full sun in the early morning, which helps reduce the incidence of disease as well as the cultivar being resistant.
Peach and Nectarines
Choose peach and nectarine tree cultivars that are resistant to bacterial leaf spot. Leaf spot can weaken trees and reduce the size of the harvest. Peach tree varieties that are resistant to brown leaf spot include the Harbelle, Mericrest Nectarine, Topaz and Reliance. Nectarine varieties resistant to the disease include Loring, Redskin and Encore. Madison and Summer Pearl nectarines are moderately susceptible to brown leaf spot disease.
Pears
Pear trees are susceptible to fire blight, but some varieties have some resistance to the disease. Varieties that show resistance include Lincoln, Maxine, Dutchess, Tyson and Kieffer. Bradford pear trees are only considered moderately resistant to fire blight, according to the University of Missouri.
Cherries
Cherry trees are susceptible to cherry leaf rot, brown rot, silver leaf and black knot. However, trees that are cultivated rarely succumb to black knot. Utah Giant and Black Tartarian is a disease-resistant cherry tree. The tart North Star cherry tree is resistant to leaf spot and brown rot.
