ROADSIDE DEVELOPMENT AND EROSION CONTROL. FINAL REPORT

The information contained within this report addresses: 1) implementation of roadside development and erosion control results, 2) herbicide evaluation for the effective and economical eradication of undesirable roadside vegetation, 3) evaluation of species and cultural practices for ground cover establishment, and 4) fertilizer evaluations for maintenance of ground covers. The following are recommendations based upon the research results: (1) For control of johnsongrass alone or intermixed with silver bluestem, and bermudagrass release, apply 1.5 pints of Roundup plus 2 ounces of Oust in 20 to 40 gallons of water per acre during May after the bermudagrass has broken dormancy. (2) To control silver bluestem alone, apply 1.5 to 2.0 pints of Roundup in 20 to 40 gallons of water per acre during May, prior to seedhead formation. (3) For brush control: a) June application of 1 gallon Tordon K plus 1 gallon Garlon 4 in 50 gallons of water per acre (broadcast) or 100 gallons of water per acre (applied with handgun and spraying foliage to wet), or b) Krenite S at 3 gallons plus a crop oil in 50 gallons of water per acre (broadcast) or in 100 gallons of water per acre (handgun) applied in August to October, prior to first fall coloration, or c) Roundup at 1.5 gallons in 98.5 gallons of water per acre and applied as a spot-treatment with handgun only. (4) Kochia can be effectvely controlled with a preemergence application of Karmex 80W at 3 pounds product in 25 to 40 gallons of water per acre, applied in February or early March, or a postemergence application of Banvel at 0.5 pounds active ingredient in 25 to 40 gallons of water per acre, applied in May or early June. (5) For preemergence control of annual grasses and broadleaf weeds, apply atrazine at 2 pounds active ingredient in 20 to 40 gallons of water per acre in February and not later than March 15. Karmex 80W can be used also at the same rate as given above for Kochia control.
