    looks like the top picture in your post. branches and twigs twisted. Were you able to get confirmation that Honey Locusts are susceptible?
    Thanks much,
    Steve
    I can post or send pics if you want.

    31Bro,
    sometimes an upload fails because the photo is too big. Crop it or reduce it to about 150 k. Sometimes it says "upload failed" when actually it was fine. Site needs a little fixing.

    Set your camera to medium or detail or less. Or use your cell phone.

    Some of those islands look rather dry--non irrigated--I am thinking. Was it hot in July? LOL!

    Look for curling, twisting, distortion, and drawstring effects on the leaves--not just brown.

    I have seen imprelis damage to honeylocust in the southeastern MI area. However, this showed up in June-July, and I would say what I see in the pictures is different from the imprelis damage I seen on the locusts. looks more like droughy conditions is causing an early color change in those trees. Although maybe the imprelis is contributing to it as well. Be sure and document it and have all records ready, Dupont is sending out representatives to check oout sites over the next month.

    I work at a forest preserve in IL. that has three golf courses. Two used the herb. and both have damage on the pines, spruce, and all the honeylocust in areas that the turf was sprayed. This week Dupont sent an arborist from davey tree and a company to take inventory of every tree that shows damage. Next we have to wait and see how much they will pay. The pines and the spruce show more damage. The honeylocust show the terminal buds that are dead or deformed on some braches and the leaves look curled like leaf hopper damage.
