Agriculture and horticulture are vital to the Harvey County economy and its residents. The Harvey County Noxious Weeds Department works to maintain and improve safe and advantageous production conditions for farmers, ranchers and citizens by treating noxious weeds.
Noxious weeds are plants that have been determined to be harmful to crops, livestock, wildlife or humans. The Noxious Weeds Department uses herbicides to halt and eradicate the spread of these plants along rights of way in the county. Harvey County also contracts with townships and the Kansas Department of Transportation to treat their respective land tracts.
