    Thats easy , use glyfosate 41% , mix 2 ounces per gal into a back pack and go for it .
    Read the label first , that's very important

    That really doesn't make much sense. Glyphosate is a contact herbicide, i.e. no residual. By digging everything up they are probably going to expose a whole new crop of seeds to conditions that may induce germination. If it's a waterway then you really can't apply a ground sterilizer like Sahara or my favourite Spike. Do these ditches empty into a fresh water stream or lake or perhaps the ocean?

    I would classifiy Glyphosate as a Localized Systemic....maybe I'm splitting hairs with you Garth...I know what your implying but many might confuse a Contact vs Systemic mode of action with your post....not picking just offering additional info

    being it's ditch, i would assume that water will flow time to time through there. i would play it safe and use a mixture of REWARD and RODEO + non-ionic surfactant for the job. they are both very effective (with this mix you will have burn down in 24hrs if mixed right) and if their is ever any question (EPA, etc) of runnoff, you are 100% covered. both are aquatic herbicides. if you can't spend the $150 gal for the reward, you can just use the rodeo (same as round-up, just no surfactant) + non-ionic surfactant for about $175 2.5gal. beat the tree huggers to the punch.

    if the chem places are doing their job, they won't sell an aquatic herbicide to someone who's not aquatic certified.....

    Still doesn't make sence if they are going to dig it up though. waste of city money.... but their waste is your gain...

    BINGO! Reward or Rodeo are designed especially for this application. Round-up is not.
