MARION COUNTY WEED DEPARTMENT: ***NOTICE***
COTTON AND GRAPE GROWERS IN MARION COUNTY SHOULD CONTACT THE NOXIOUS WEED OFFICE TO PROTECT THEIR SENSITIVE CROPS FROM DAMAGE BY HERBICIDES BEING APPLIED TO ROADSIDES THROUGHOUT THE COUNTY. WE ONLY HAND/SPOT SPRAY NOXIOUS WEEDS INSTEAD OF BROADCAST SPRAYING THE ENTIRE DITCH.
The Kansas Legislature has declared 12 weeds as noxious. They are:
Two additional weeds are County optional, Multiflora Rose and Bull Thistle. Neither has been declared noxious by Marion County. Please see the Kansas Department of Agriculture link below for pictures and methods of control.
The four weeds listed in bold type above are the ones currently infesting and considered noxious in Marion County. Leafy spurge and hoary cress have been found and treated in isolated spots and are being monitored for re-growth.
Chemicals available at the Noxious Weed Office are for the treatment of noxious weeds only. All sales are final. When purchasing chemicals at the Weed Office, bring your checkbook or cash (we cannot accept credit cards), the name of the owner, operator, applicator, legal description of the land, name of weed to be treated and per acre amount of application. If you wish to purchase Tordon 22K, you must have a valid private or commercial applicators license to purchase. We will verify that it is current when you come to purchase this chemical. If you are having someone besides one of the cooperatives or chemical spray companies, that person with the applicator license must be present when the purchase is made as they have to sign invoice at that time. NO EXCEPTIONS!
Chemicals available for purchase for Noxious Weeds:
- 2,4-D Amine #4
- 2,4-D Lo Vol #4
- Dicamba (Banvel)
- Escort XP
- Glyphosate (Round Up)
- Tordon 22K (must have applicator license to purchase)
Cost Share Certificates are also available from this office. These act as discount coupons for purchase of approved chemicals from chemical dealers. These certificates shall be issued prior to the chemical purchase. We also work with the local coops and spray companies, including aerial spray companies, to provide the cost share certificates after the acreage has been sprayed to get an accurate amount of chemicals used.
Before issuing a cost share certificate, the weed office needs to know the name of the landowner and operator, name of the applicator, type of weed infestation, legal description of the ground, per acre rate of chemical application, and number of acres to be treated.
