The Grant County weed superintendent is the county’s noxious weed control authority, and it shares that officer with Hooker County, working from the office at Mullen. Nebraska law requires every county to have one. The office inspects land for the weeds on the state noxious list — musk and Canada thistle, leafy spurge, phragmites, knapweed and the rest — and can require a landowner to control them, doing the work and billing for it if a notice is ignored. It is also the office to ring if you want to know what is spreading in your area, what to spray and when, or who is responsible for a roadside. Mullen is in Hooker County, so Grant County landowners are served from over the county line. Grant County publishes only a post office box, so there is no street address to give.
