    this is what the new growth does . instead if growing it just curls up and turns brown.

    Leaf Spot Tree Disease - Prevention and Control
    From Steve Nix,

    Leaf infections called "leafspots" are caused by a variety of fungi and some bacteria on many trees. An especially harmful version of this disease is called anthracnose which attacks many tree species including dogwood and sycamore. Positive identification usually requires laboratory diagnosis.
    Symptoms: A leaf spot disease creates spots on foliage. The spots will vary in size and color depending on the plant, the organism involved and the stage of development. Spots are most often brownish, but may be tan or black. Concentric rings or a dark margin around the spot may be present. Over time the spots may combine to enlarge and form blotches. Spots or blotches that are angular and located around the veins are generally referred to as anthracnose. Leaves may yellow and drop prematurely.
    Prevention: Good tree care is sufficient for prevention. Avoid crowding plantings too closely. Thin out branches to open up the tree crown, but don't top or dehorn. Rake up leaves in fall and bury or compost them. Plant different kinds of trees in mixture. Fertilize trees in the spring with a complete fertilizer. Water trees deeply during dry spells. Do you know how to keep your tree healthy?

    Control: Use fungicides only when necessary. They MUST be applied prior to buildup of disease to effectively control leafspotting fungi. If severe leafspotting and/or defoliation occurs for several years, chemical control is probably necessary, but the leaf spot variety should be identified first. You can submit samples to your county agent for identification. Timing of protectant fungicide sprays is critical and varies for different fungi. Correct timing is a key to effective chemical control.

    i think this is the problem, though i could be wrong.

    maybe your grub control damaged the tree? it is a small tree so it isn't out of the question, but as said above is good advice.

    it doesn't look like its worth saving. if you destroy it, be sure to put all limbs in plastic bag or burn it so you dont transfer the fungi elsewhere. i wouldn't plant another tree in the same area until you treat the soil for fungus...which might not work.

    I bought the 3rd edition years back. it was like 1300 page hardback cover. this book contains color photos of all diseases, and is an extremely good book to have for reference, plus it lists what type ortho chemicals to use. the info is from county extension offices through out the nation. you can buy it bran new for about 200 bucks. Home depot/lowes used to have these books on display where customers could look thru them. some nurseries have them also. my book got stolen. sad, sad...

    When trees are in a weakened state, a whole host of things starts to attack it. The tree is garbage now. One of those pictures looks like Midge, but I'm not sure if they infest Ash. It mostly looks like last years budset was severly injured. Young trees are more susceptible to frost,bark splits,etc. You also might check and see if the ropes around the ball were cut when it was planted. ??????? I don't think insecticides had anything to do with it.

    Just a thought, but did you plant the tree? We find alot of this with new construction homes where the Mexicans forgot to take the basket off. Especially with Fischer Homes.
