The Weed Control Program enforces the Maryland Weed Control Law and assists farmers or landowners in the battle against the designated noxious weeds Johnsongrass, shattercane, and thistles. The law requires landowners to manage noxious weeds on all types of land. Johnsongrass and thistles are considered two of the more persistent and destructive weeds in Maryland since they are very difficult to eradicate. Both the seed and the root system of these weeds must be managed for effective control. Control methods include cultural, physical, mechanical, biological or chemical. MDA enters into an agreement with each of the 16 participating counties to provide technical assistance to landowners for initiating noxious weed control programs.​
