Our crab apple trees in our front yard have spots on the leaves and they are now falling off of the tree. The berries are also out on the tree which I thought come out in the fall. I read on the Apple Valley website that this could be apple scab? Is there anything we need to do to treat the trees?
The cold wet spring and summer we’ve had has caused excessive problems with apple scab for many people, so you are not alone. Not a lot can be done for the crab apple trees this year, but I can give you some suggestions for next year. There is a fruit tree spray on the market that is recommended for this problem. It should be applied early in the spring, before the first buds appear. Some people have used it later on, and even at this time, but it is less than effective. It is strongly suggested to be used early in the spring. Ortho makes a product that has been known to help with this situation. Just look for a fruit tree spray product, and read the label to see if apple scab is mentioned. Thanks for writing.
Genial dispatch and this enter helped me alot in my college assignement. Gratefulness you as your information.
