I'm usually not true to one paticular product/brand name. I stumbled on Cide Kick II surfactant. I haven't used it in anything but a spot sprayer, on woody plants. It seems to amplify the killing power of whatever herbecide you are using. Evidently it helps penetrate the leaf, and bark. I have a species or two, that I have fought like the plague for a long time. I kill them just to spray them again the next year. I've only used this stuff, this summer, but it looks promising. The honey locust I've sprayed with it the stems are dead, and will snap if you try to break them. The stems of honey locust I sprayed before I started using this stuff are still rubbery. Pretty sure they are going to make an appearance next spring. It's pretty cheap to for something that works good. I will add, it does seem to make broad leaf herbecides kill grass. It doesn't reall kill grass to the ground, but it looks dead. It will come back from the base pretty quickly. It's like you left a board laying for a couple of weeks, and then moved it. It doesn't bother me that does it, because if these honey locust become a non issue, I'll gladly kill a little grass to get the job done. Just thought I would share a product that does, what it says it will do.
