    I got a customer who has a long road that is a drive to his home. I mow all the ditches weekly and have for years. He aproached me about cuttign down the grass growing around the culverts and some areas that are just too steep to mow or trim. Is there a chemical that will burn down the foliage but leave the roots intact, so not to cause erosion and not kill off the grass? With all the areas its about 2k sq ft. Like I said most is just way to steep to trim.

    When you say "leave the roots intact", are you asking if they'll still be viable (for future growth)?

    Just curious. I'm interested in hearing from the experts on this one, also. I'm currently exporing a good mix to do something similar. Right now, I'm leaning towards a gly./ammonium sulfate mix. I'm also exploring adding in a Pre-emerg. for the second app..

    yes, leave roots intact for future growth.

    Scythe may work. Organic fatty acid that hastens the burn down of gly.

    Reward + a nonionic surfactant will work very well. Non systemic top kill in 24-48 hours of both grasses and broadleaves. Spray to wet, do not inhale, ingest or get on skin or eyes.

    I agree with greendoctor, but would you consider PGR's.

    Flurprimidol.....Cutless, Legacy, Mastiff, Topflor is growth regulator's for turf. These will slow down the growth and mowing frequency and not destroying the integrity of the root systems.
    Reward (Diquat Dibromide) will burn down vegetation only and leave the roots....!

    you could chemical mow it for cheap using glyphosate.

    4ml/1000 sq ft for KBG or 5.4ml/1000 sq ft for fescues in 1 qt to 1 gallon /1000 sq ft (isopropylamine salt)


    3ml for KBG or 3.85ml for fescues in 1 qt to 1 gallon per 1000 sq ft (potassium salt)
