Roadside Vegetation Field Condition Study

It was questioned whether the use of herbicides would improve MRP turf scores by controlling undesirable broadleaf weeds. Plots were established in North and South Florida on areas that the Project Manager determined would fail to meet MRP standards due to weed pressure. These areas were treated in 2010 and 2011 with aminopyralid and triclopyr, two herbicides proven to be effective on the weed spectrum present. Spanish needles was the dominate weed at both locations. The herbicide application provided highly effective control of Spanish needles and other broadleaf weeds. In the absence of weed pressure, the desirable perennial grasses began to expand and cover these void areas. It was determined by the Project Manager that though these areas initially failed to meet MRP standards, they did meet standards after the herbicide applications.
