Apple scab is one of the most serious diseases of apple and crabapples. Disease development is favored by wet, cool weather that generally occurs in spring and early summer. Both leaves and fruit can be affected. Infected leaves may drop, resulting in unsightly trees with poor fruit production. This early defoliation may weaken trees and make them more susceptible to winter injury or other pests. Infected fruits are blemished and often severely deformed. Infected fruits may also drop early.

| . Apple Scab of Apples and Crabapples. Apple scab is one of the most serious diseases of apple and crabapples. Disease development is favored by wet, cool weather that generally occurs in spring and early summer. Both leaves and fruit can be affected. Infected leaves may drop, resulting in unsightly trees with poor fruit production. This early defoliation may weaken trees and make them more susceptible to winter injury or other pests. Infected fruits are blemished and often severely deformed. Infected fruits may also drop early. Control measures for apple scab include selection of scab resistant cultivars of apples and crabapples, raking and destroying of fallen leaves, and fungicide sprays. Triple Action Plus with Neem Oil is the most effective spray. It is an oil spray that will actually stop the scab from spreading. |
