Louisa County Noxious Weed Notice



The Louisa County Weed Commissioner announces that the deadline for destruction of Noxious weeds is June 1st, so as to prevent the production of seed by all varieties of listed Noxious weeds. This includes weeds on farmlands, Conservation Reserve Program (CRP) lands, properties within city limits, and all lands within the limits of the County. Those persons not controlling their weeds in compliance with Iowa’s Weed Law, Code of Iowa Chapter 317 Noxious Weeds, and Iowa Dept. of Agriculture & Land Stewardship Administrative Rules Chapter 58 Noxious Weeds will be notified to use appropriate methods to eradicate or control the weed problem. Failure to do so can incur penalties including, but not limited to, daily fines for non-compliance, and the Weed Commissioner or Deputies entering upon the land to control the weed problem, with all costs, including fines and administrative costs, levied against the landowner. Iowa law provides these assessments can be attached to the real estate tax of the land for collection. Weed eradication/control will still be required to be implemented in all cases where penalties are assessed
