The RM of Hanover recognizes that noxious weed control is necessary for agricultural and residential reasons. The weed control program consists of mowing of drains and roadsides along with chemical applications when necessary for heavily infested areas. Invasive species of noxious weeds are watched for across the municipality, recorded, and reported as required to the Province of Manitoba.

Mechanical mowers are used as a first method of choice for yearly control of vegetation along roadsides. This is a partial control of problematic weeds, and also for the purposes of safety and better efficiency of drains. This begins around July with mowing along the shoulder of the road covering approximately 15 feet.  Later in the year, usually in September, another round of mowing along the shoulder is completed as well as further into the ditch to mow the bottom and back-slopes to further control vegetative growth and for better flow during the spring runoff season.

In Areas that are heavily infested with problematic weeds RM of Hanover has trained and certified staff for the application of chemical pesticides.  This method is used only when other regular mechanical mowing is insufficient and areas are too large for physical pulling of noxious weeds by hand.

The RM of Hanover has appointed the Manager of Public Works and Operations as the municipal weed inspector.
