    It is a flowering crab apple. Those (cankers) are disease. Not sure how they get there but have a feeling that they are caused by wasps laying eggs in the bark or some other insect. Try to cut each one out and burn them. Do not put in waste. Contact your local county extension agent with some of them. He/she may know of a insecticide/fungicide to treat them. You may have to hire a pro to inject the root area. Let me know what you do. Read this: http://www.ehow.com/how_5844882_save-diseased-crabapple-tree.html

    Its an infection that can spread from tree to tree. You may want to call yur local dept of agriculture office and have the out breAk reported , DO NOT CUT the cankers off and throw in trash, by cutting it you are releasing the spores into the air. A fungicide spray may suppress the spreading.

    I will be calling them monday. Any Ideas what I could spray it is real bad in this tree and small spots on another. I am Licensed but like I said not a tree guy I just picked up a spray contract and am also mowing and just mulched it. Would love some ideas. I want to get on this quick.

    spectator, 1 ounce in 25 gallons of water

    spray until it drips

    then do it every spring as a preventative even if its not a fungus

    it prevents apple scab

    Black Knot of PRUNUS.

    Looks too far gone to supress with Daconil............Single Prune with a chain saw.

    Best of luck.

    That is the worst case of canker I have ever seen.
