FAQ

  • What does the Yankton County Weed & Pest Department do?

    We control declared noxious weeds, along State and Local County Right-of-Ways and most Township Roads. We also enforce South Dakota Weed Laws per SDCL 38-22. We also provide mosquito control to local towns that contract with us.

  • When do you spray?

    We usually start sometime in May and continue until October.

  • What do you spray?

    We spray all declared noxious weeds, state and local, as listed on our web page. We try to avoid spraying any wild flowers, milk weed, etc... for pollinators.

  • Do you spray the entire ditch?

    No, we generally try to spray only where there are noxious weeds - spot spray. We may do a fine continuous spray along County Roads only in the late fall.

  • What chemicals do you use when spraying?

    Our most common tank mixture is 2, 4-Choline - 32 oz per acre and Tordon 22k - 16 oz per acre rates.

  • Who do I contact if I have a noxious weed compliant within city limits?

    Yankton County Weed does NOT have jurisdiction within the City of Yankton. The City's weed ordinance is posted along with other municipal codes online. Residents have the responsiblity to control vegetation on their property. If weeds become a nuisance, the City of Yankton will take action. Please contact Public Services at 668-5251 to file a complaint.

  • What if I don't want the Right-of-Way sprayed in front of my property?

    You can complete this No Spray Form and send it into our office. The No Spray Zone needs to be properly marked at the beginning and the end of the zone. If you have a No Spray Zone, you will be responsible for control of the noxious weeds in it.
