Can I use Bonide Liquid Copper Fungicide Concentrate to treat an old apple tree that I believe has apple scab?

I need a fungicide I can put around the diameter of the tree. I can't spray because it it is too big. I have looked everywhere. I don't want this tree to die!


If the tree is affected by apple scab, then you will have to spray with something like Bonide Liquid Copper Fungicide Concentrate as this disease is treated topicallly by contact with the foliage.  Try to get a sample of the tree to take to a local Master Gardner in your area to see if you can identify exactly what you have to make sure you are using the best products for your needs.
