Expert Response

The picture you attached shows the disease apple scab. Your apples probably have the same disease. You will need to start making dormant sprays with Bravo in the fall about Thanksgiving timeĀ and Lime sulfur around the end of February. These two fungicide sprays will be good for any fruit trees you have. Once the trees start growing in the spring and bloom has finished then give them another fungicide spray using either Immunox or lime sulfur. This should help to remedy the scab problem. You should also mow up or rake up old leaves from your fruit trees that might have these apple scab infected areas. These infected spots supply new spores to reinfect the new leaves next year.
