The Florida Department of Agriculture and Consumer Services held a controlled burn of cogon grass along Freeman Rouse road in Wewahitchka to destroy the weeds that had infested a local field. Prior to the burn, the grass was killed with herbicide treatment to prevent the spread of seeds.
Cogon grass is an aggressive and invasive noxious weed that spreads through airborne seeds and creates efficient rhizomes deep in the soil. Once established, the grass is difficult to control and full eradication may take three to five years using herbicide treatments.
Due to the difficulty of removal, the grass poses a threat to forests, agricultural lands and other natural areas. If not properly managed the grass, which is not viable livestock forage, can become a fire hazard, decrease plant diversity and wildlife quality, and lower the value of real estate.
If cogon grass is posted the Florida Department of Agriculture and Consumer Services should be contacted for treatment advice.
