Section 4: Types of Control
Anchor: #i1022285Bare Ground (or Complete) Vegetation Control
Bare ground situations may be appropriate where there is a specific reason for such a treatment. Treating the edge of pavement or vegetation encroachment within paved shoulders are good examples where bare-ground herbicide rates may be appropriate.
Continuous bare ground treatment, especially on sloped areas, increases the potential for erosion and sediment loss. For those areas, additional spot-treatments may be necessary.
Applications to the edge of pavement will not be any wider than 6 inches from the edge of the paved surface and 12 inches behind the guardrail. Applications wider than 12 inches may result in erosion and soil sediment loss.
Application of an excessive quantity of herbicide is not economical and may result in damage to nearby desirable vegetation.
CAUTION: Complete control may be achieved by using Roundup Pro at a rate of four quarts per acre plus Landmark XP at two to three ounces per acre. Bare ground is not recommended under guardrails or around signage, delineator posts, mailbox supports, etc.
Anchor: #i1022311Selective Weeding
Selective weeding is the use of an herbicide or a combination of herbicides for the control of target plant species which does not permanently harm desirable vegetation. Herbicides used for this type of control may be selective or low rates of non-selective herbicides. Examples would be:
- Roundup Pro at 8 ounces per acre plus Outrider at 1.33 ounces per acre for the control of Johnson grass
- Escort XP at a rate of one ounce per acre for the control of Field Bindweed and Common Sunflower
- Transline at a rate of 10 ounces per acre for the control of weeds such as Must Thistle and Giant Ragweed.
- Vista at 10 ounces per acre plus surfactant at the rate of two quarts per 100 gallons of water for Giant Ragweed control.
Chemical Mowing
Chemical mowing is the practice of using Roundup Pro to control undesirable vegetation in close proximity to desirable plant material. This procedure may be used to control vegetation along fence lines, under guardrails and within landscaped areas.
