How does apple scab damage trees?
Scab is a disease that can destroy an apple or pear crop. Young, infected flowers or fruit can drop, or the fruit can become malformed, cracked, and unsightly, rendering it unusable. Defoliation follows severe, early leaf infection.
Apple scab is a fungal disease that attacks the leaves, fruit, and twigs of apple trees. The disease is caused by the fungus Venturia inaequalis, which overwinters in fallen leaves and infected twigs. In the spring, the fungus produces spores, which are dispersed by wind and rain onto the newly developing leaves and fruit. The spores germinate and enter the plant through stomata, or pores, on the leaf surface. Apple scab can cause severe defoliation of apple trees and can also cause fruit to be deformed and discolored.
Apple scab can be controlled with fungicides. Fungicides should be applied when the spores are first released in the spring, before they have a chance to infect the leaves and fruit. Fungicides should be applied again at 7- to 10-day intervals throughout the growing season.
Is it too late to spray for apple scab
Fungal diseases can be a big problem for plants, especially in the springtime. The fungi that cause these diseases release spores and infect plants in April and May, which is when a fungicide will be most effective. After leaf spots have developed, it is too late for fungicides to work well. So, just as tree buds begin to swell and green leaf tissue is showing, is the time to begin applying a fungicide.
Apple scab is a fungal disease that can cause cosmetic blemishes on the fruit. Fruit with apple scab is still edible, but it can also infect hawthorn and firethorn.
Does apple scab affect other trees?
The apple scab fungus is a serious problem for apple growers because it can cause extensive damage to crops. The fungus has several host-specific strains that can cause disease on one type of plant but not any other. For example, the strain of V inaequalis that infects mountain ash will only infect other mountain ash trees and will not infect crabapple trees. This is why it is important for apple growers to know which strains of the fungus are present in their orchards and to take steps to control them.
Fungicide application is an important part of scab control in apple trees. Application must begin in early spring, and continue on a 7- to 10-day schedule. If dry weather persists after petal fall, a 10- to 14-day spray schedule is adequate for scab control.

How do you treat apple scab disease
Home gardeners who remove all fallen leaves from under their apple trees should experience good control of apple scab. Leaves may be safely composted. Foliar application of a 5% urea solution in autumn just before leaf drop will speed natural decomposition of leaves and help to deactivate the scab fungus.
Fruit set is the beginning of the fruiting process in plants. Fruits are typically spaced every 10 to 14 days apart during the growing season. All spraying should be discontinued 4 weeks before harvest, or according to the label directions. This will help to ensure that the fruits are safe to eat.
Will neem oil treat apple scab?
