Weed Control

A sign reading "Roadside prairie restoration, no spraying or mowing" among greed roadside vegetation.

Iowa Code section 317.11 states: The county boards of supervisors and the state department of transportation shall control noxious weeds growing on the roads under their jurisdiction. Spraying for control of noxious weeds shall be limited to those circumstances when it is not practical to mow or otherwise control the noxious weeds.
