    I've been using round up concentrate-brush killer in this ditch...it'll kill the weeds, but after about 2 weeks, they are back again. the ditch does hold water so i can't mow it. is there another weed killer better than round up, or is this just a problem i'll just have to deal with because of the water in the ditch?

    all roundup does is kill weeds. it does not sterilize the soil. and if you have a wet area, your water loving weeds will keep coming back.

    I'd be real hesitant about spraying too much in a drainage ditch. you kill the weeds/grass, and now the water flows faster and begins taking exposed soil with it. and now you have erosion...

    You also need to worry about poluting the water if it drains off into any water natural water flows

    I was going to say,...If you are spraying pesticides in a waterway, growing grass or weeds is the LEAST of your worries.:nono: :dizzy:

    If you are spraying in an area that drains or retains water and contamination occurs you are in deep do - do.
    There are several aquatic vegetative control herbicides on the market - I'd check with the local extension agent to see which one is best suited to this situation.
    Presuming you do have a license - right?
