    Severe Cottonwood Leaf Rust on Young Trees

    I've got 3 7' 3 year trees that have been severly infected this year and last. The infection starts mid July, and the leaves are all but toast by now. They are growing in with a line of Black Spruces, and cutting any of the trees is not an option.

    I've read to pick up any of the dead leaves and burn them, but I don't remember many of them laying on the ground last year to cause the infection so is there any other treatment for my trees? Some kind of fungicide maybe? And if so what kind and where to buy it?

    RE: Severe Cottonwood Leaf Rust on Young Trees

    My young WhiteAshes on a reforestation plot did the same thing for like 3 years in a row and the last two, no such thing. Puzzling but glad to see it gone. It even affected my Tulip Pops to a lesser degree but no sign this year. They would get spotted in June and be defoliated by August(still lot of growing season left here in August) This year and last year no sign of the virmin. These were and still are small trees. The highest 20' and most at around ......say....... 8-15 ft at this time. Hopefully yours is the same benign bug.

    goodluck

    Thanks

    And depending on where you are you'll be reforesting that reforested plot if Emerald Ash Borer is all it's cracked up to be.

    Anyone know what spray or fungicide I could use though?
