    My son has just recieved his liscence for application of herbicides. The HO has bought the garden variety stuff in the past and sprayed it on , but to no avail. Now this year the situation is critical and we need the weeds gone now.
    Ground temps around 50 degrees here in central Wisconsin.

    What would work best? Any help would be appreciated.

    Where is he that he has his license ?

    At Lesco/Deere, he can get Three Way Ester II for cool season weeds like that.

    But tell him he's got to switch over to an "amine" (water based) formulation once the weather starts to get on the "warmer" side (when the daytime temps get consistently into the upper 70's-lower 80's).

    Also...with the "ester" (alcohol based) formulations like Three Way Ester II, he should be ESPECIALLY careful about NOT spraying "under" bushes and / or tree driplines during "questionable" temperatures !!!
    An applicator can actually "burn" newly emerging buds & leaves WITHOUT actually spraying them, because alcohol-based liquids can and will volatilize, especially as the temps rise a little.

    A few trees I've known to be especially sensitive:
    Dogwood, Eastern Redbud, Hawthorn, Mimosa, + any "weeping" landscape trees hanging over turf.

    Thanks guys.
    We don't have a Lesco around here that I am aware of and the Deere location may not even carry chemicals. I will try the Co-op and Jay-Mar and see if they carry any of these items.

    It seems I read one time about adding a 'sticker' to the solution in order to get it to stick to the leaf better. Is that a good thing to do?
    Browsing the threads it seems there are a number of tricks you guys have picked up on over the years. Thanks again...

    A 'sticker' is short for 'speader-sticker', or a substance something otherwise known as a surfactant.

    I use, specifically, a "non-ionic surfactant", in everything I do, including turf landscape and nursery applications.

    You're halfway correct with your definition.
    It does help the herbicide / insecticide / fungicide "stick" to it's target better.

    But a surfactant also defeats the hydrogen bond on a given surface to a degree...allowing the liquid to "spread" over the surface without 'beading up' so much.
    This gives the applicator a higher % of target actually "hit", when it's sprayed.

    For example:
    Closely look at a patch of white clover sometime after you spray it with just plain ol' hose water.
    See how the water just 'beads up' on the small leaves ?
    Now...on a different patch of clover, do the same thing, but this time...use a hose-end sprayer with a modest amount of dish soap in it !!

    Some "newbies" who don't have spray tanks with mechanical agitation actually do run around with backpack sprayers or whatever, with little bottles of Dawn / Palmolive, etc.
    But obviously, if you wouldn't want to try this trick once you've invested the $$$ in the spray rig with jets or paddles.

    If you might look sorta like the pathetic scene from the infamous Brady Bunch "kids put too much soap in the washing machine" episode !!

    how cheap can somebody be as to use dish soap?? buy a surfactant thats labled for lawncare. i've seen and heard people use soap, but come on your a pro. i'd like to see the look on the pesicide inspectors face when a guy told him he had tide in the tank mix, that would be a true kodak moment. ((this was not directed toward any persons post, just my thoughts on the matter))

    cool power works great, you might try adding a surfactant, but becarfull not to over apply or you can cause damage to the turf and ornamentals... this time of year your weeds shouldn't be mature enough to warnt the surfactant (if your temps are still that cool, but you be the judge). also remember no matter what you use, the weeds will pretty much die as quickly as there growing.

    do you have a tractor supply around? they carry LV4 which is an ester 2,4d and it will work fine. they also have speedzone, which is a newer type of broadleaf herbicide that has a very quick knock down and its also an ester (it cost about twice as much as anything else thats why i dont use it, again you be the judge)

    Small Axe, you say central Wisconsin. Where exactly are you? I am near Fond du Lac and could give you some suggestions. The CO-OP will probably have MecAmine-D which will work with a sticker, but it will be slow. I am starting my weed control tomorrow with Speedzone. The soil temperatures are in the low 50's and there is a chance of frost tonight.

    Esters kick butt during cool weather. They also control hard-to-kill weeds better than amines (nomatter what the temps are). Chaser ester (UAP) is great. UAP/Loveland just improved their LI-700 --- a new product called Liberate does what LI-700 does, but it also contains anti-drift/anti-foam

    Ummm - Smallaxe - Didn't think I would see you on this side. Your closest Lesco/John Deere is here in Madison - they just moved to a new site in Middleton. If the lawn has a lot of creeping charlie or violets, I would recommend their Momentum FX. You need to use a spreader/sticker for best results.
