Mississippi Department of Transportation

District 6


Introduction to cogongrass

Introduction to Cogongrass

  • District 6 – May 2002

    * Cogongrass already at level that seemed insurmountable.

    * No measures being taken to combat this widespread problem.

    * Where do we go from here?


Starting the process

Starting the Process

  • Cogongrass Awareness

    * Meeting in Kiln, MS formed the Mississippi Cogongrass Taskforce.

    * Public education and measures to be taken for combating cogongrass.

    * Meeting in Waynesboro, MS brought about “Good Neighbor Policy”.

    * Creating a plan of action for the MDOT in

    District 6.


Good neighbor policy

“Good Neighbor Policy”

  • Implemented mainly by word of mouth.

    * Bureau of Plant Industry and NRCS grants.

    * Mississippi Coastal Plains RC&D education program.

    * Organizations such as MVMA, NRVMA and Southern Weed Science Society.

    * Employees of MDOT spreading the word when approached by the public.


How the good neighbor policy works

How the “Good Neighbor Policy” works.

  • A landowner calls in to a MDOT Office and states that they have cogongrass adjacent to their property.

  • Meet with the landowner to get the boundaries of their property.

  • Make the herbicide application on the site.

  • Keep in contact with the landowner to spray any re-growth.


Working with partners

Working with Partners

  • Partnership formed with MDOT, MSU and DEQ on a seedhead suppression study on Highway 63 in Jackson County.

  • Applying several herbicides with the intentions of cutting down on the number of windblown seeds.

Working with partners continued

Working with Partners continued

  • Embarked on a partnership to spray an area of interest in four coastal counties.

  • Parties involved included MDOT, Coastal Plains RC&D, USDA, NWTF, NRCS, U.S. Forest Service and the counties involved.

  • In the process of erecting signs for public awareness.


Herbicide mixtures for cogongrass

Herbicide Mixtures for Cogongrass

  • Mixture for areas with no hardwood trees:

    * Glyphosate – 2% V/V

    * Imazapyr (2 lbs. A.I.) – 1% V/V

    * Non-Ionic Surfactant - .25% V/V


Mixtures continued

Mixtures continued

  • Areas with hardwood trees:

    * Glyphosate – 2% V/V

    * Non-Ionic Surfactant - .25% V/V

  • Seedhead Suppression:

    * Imazapic – 12 fl oz./acre

    * Non-Ionic Surfactant - .25% V/V


Initial control practices

Initial Control Practices

  • Targeted four lane systems.

  • Landowners that called in for the “Good Neighbor Policy”

  • Seedhead Suppression on areas that were highly infested.


Current practices

Current Practices

  • Still targeting four lane systems.

  • Spraying of areas that have re-growth or was missed on the initial application.

  • Adapting the “Good Neighbor Policy” to include whole routes when able.

  • Spraying new construction areas before the start of initial clearing.

  • Spraying newly established construction areas when cogongrass is detected.


Current practices cont

Current Practices cont.

  • Continuing our seedhead suppression program this winter.

  • Avoiding areas in our mowing cycle with cogongrass in bloom.

  • Making sure mowers are cleaned before leaving a cogongrass infested area.

  • Working closely with Coastal Plains RC&D on more areas for partnership.
