General EAB biology, distribution, management, regulation, and insecticide treatment will also be covered. Workshops will be offered three times each day at 9 a.m., 10:30 a.m. and 1 p.m. Workshops are provided free of charge through support from the US Forest Service.

New Weeds on the Minnesota Noxious Weed List

The MDA has added six new weeds to the state’s Noxious Weed List. The Noxious Weed List places weeds into four categories, Prohibited Eradicate, Prohibited Control, Restricted, and Specially Regulated, and defines how the weeds must be controlled. Three weeds on the list also changed categories.

The six new species added to the list are:

The three species that changed categories are:

  • Japanese knotweed (Polygonum cuspidatum) and giant knotweed (P. sachalinense) were moved from Specially Regulated to Prohibited Control.
  • Tree of heaven (Ailanthus altissima) was moved from Restricted to Prohibited Eradicate.

Using Drones to Combat Noxious Weeds

Noxious weeds, characterized by their aggressive behavior, continue to be an increasing problem throughout the United States. Early detection is critical in order to contain and/or eradicate an infestation. Ground-based surveys for weeds require time and money to cover a relatively small area. The data collected from ground-based surveys may only provide a limited amount of information regarding the extent and spread of any target weed. Remote sensing, using an unmanned aerial vehicle (UAV), can provide a more efficient method to map and monitor an area for noxious weeds.

Noxious Weeds in Eight New Counties

The MDA confirmed in 2019 five species of weeds on the state’s Noxious Weed Prohibited Eradicate List for the first time in eight counties.

Weeds categorized as Prohibited Eradicate are the worst types of weeds. The law requires species on this list to have all above- and below-ground plant parts destroyed because the weeds may be harmful to public health, the environment, public roads, crops, livestock, or other property.

Collaboration with multiple agencies and organizations throughout the state, including County Agricultural Inspectors, township supervisors, and city mayors, helps the MDA successfully detect noxious weeds on the eradicate list and confirm unrecognized species.

The new finds were:
