    I want spray my fence line but don't want to apply if it's not gonna be effective. Have a lot of weeds and wildgrass in the metro-Detroit area hardened too much?

    You should be okay to spray Roundup now as only some annual weeds may not be actively growing. I sprayed Prosector (Roundup) this morning on tall fescue, and I know it will work fine.

    As long as the vegetation is green, the roundup will work. I know farmers that spray into Nov. Obviously it's not as fast to show, but it will work. I'm actually going through my last round of veg. control next week.

    To kill late in the year when photosynthesis slowed, tank mix a kicker with glyphosate to blow up the outside cell walls of the target plants. Try Scythe (pelargonic acid), Reward (diquat), Octane (pyraflufen ethyl) or Quicksilver (carfentrazone) or maybe even a 2,4-d based product to help with the broadleaf weeds.
