The purpose of this County office is charged with:

  1. enforcing the State Noxious Weed Law within the County boundaries and
  2. providing information and material to help control and eradicate noxious weeds

The Kansas Legislature has declared 12 weeds as noxious. They are:

Musk Thistle Field Bindweed Canada Thistle
Leafy Spurge Russian Knapweed Kudzu
Bur Ragweed Quackgrass Sericea Lespedeza
Pignut Johnson Grass Hoary Grass







The four highlighted weeds are currently infesting Cloud County. Musk thistle, field bindweed, and johnsongrass has been treated in Cloud County for many years. Sericea lespedeza is the “new weed on the block” with land owners showing much concern and interest in controlling it.

The Kansas Noxious Weed Law, KSA, Chapter 2, Article 13, requires all persons who own or supervise land in Kansas to control the spread of and to eradicate all weeds declared by legislative action to be noxious. Copies of the State Weed Law are available at the Noxious Weed Office.
