USDA. ARS. Down on the Farm.

Currently, most cogongrass is controlled with herbicides, which only serve as a temporary solution. The herbicides must be reapplied every 6-12 months. ARS scientists in the U.S. and overseas are investigating biological control of cogongrass by collecting and studying insects that feed on the grass where the weed originated. These insects will be screened over many years to determine if they will be safe, and only those that cause no harm to valued plants will be released.
