Managing Invasive Moths in Northeast Minnesota

The Minnesota Department of Agriculture (MDA) and partner organizations are proposing to treat gypsy moth (Lymantria dispar) infestations this spring at four sites in the northeastern part of the state.

The four proposed treatment areas include approximately 75 acres in the city of Duluth, nearly 500 acres in the city of Cloquet, and two areas in Lake County totaling approximately 45,100 acres (Two Harbors NE area and Upland Trail area). Residents can view an interactive map on the MDA website to determine if they’re located within one of the proposed blocks. The treatments will be conducted in June and July, depending on insect development and weather. Residents in proposed treatment areas are invited to a virtual meeting to learn more about the insect and the treatment methods.

Gypsy Moth Name Background Information

As of July 2021, the Entomological Society of America discontinued the use of “gypsy moth” as a common name for Lymantria dispar. A new common name has not yet been selected. The changes will need to be reconciled in accordance with federal and state regulations. The Minnesota Department of Agriculture is committed to phasing out the discontinued common name and adopting the new common name when available.

What insect has been crawling inside my home?

During times of warm weather this winter, you may have noticed a few insects active in your home. Some examples of these insects include box elder bugs, lady beetles, and the invasive brown marmorated stink bug. The MDA is tracking brown marmorated stink bugs throughout the state and would like you to report if you see them outside the Twin Cities metropolitan area (Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, and Washington counties).

Please take a clear picture of the insect or collect the insect for identification. More information on how to report can be found on the Report a Pest webpage.

Field Workshops: Emerald Ash Borer

Please join Minnesota Department of Agriculture staff at one of our free emerald ash borer (EAB) field workshop training sessions being held at multiple locations throughout the state. These hour-long outdoor workshops will provide an opportunity to get a firsthand look at EAB-infested trees and will assist the community in becoming familiar with early detection. Workshops are free of charge through support from the US Forest Service. Hour-long sessions will be held most days at 9:00 AM, 10:30 AM, and 1:00 PM.

EAB Topics Covered

Life cycle, host trees, recognizing EAB, progression of symptoms, distribution, quarantines, cold mortality, insecticides, biological control agents, biosurveillance, management approaches, reporting trees and visual inspection of on-site EAB-infested ash trees.

Details

  • Dress for the weather as the workshops are held entirely outside
  • Bring a pair of binoculars if you have them
  • Cancellations due to severe weather only
  • No restroom facilities are available on-site at most locations. Please plan accordingly
  • Continuing Education Units (CEUs) Provided (1.0 credits) for ISA Certified Arborists

Grant Opportunity: Lawns to Legumes

The Lawns to Legumes pilot program offers a combination of workshops, coaching, planting guides, and cost-share funding (individual support grants) for installing pollinator-friendly native plantings in residential lawns. The program also includes demonstration neighborhoods, which are pollinator programs run by local governments and nonprofit organizations with support from Minnesota Board of Water and Soil Resources (BWSR), and a public education campaign to raise awareness about creating pollinator habitat. BWSR is partnering with Metro Blooms and Blue Thumb – Planting for Clean Water to administer the program. Find details on Individual Support Grants, Demonstration Neighborhoods, public outreach, and more can be found on the BWSR Lawns to Legumes website.

Funding is provided by the Environment and Natural Resources Trust Fund (ENRTF) and is targeted in priority areas to benefit the Rusty patched bumblebee and other at-risk species. 

Applications will be accepted through February 15, 2022.

Weed of the Month: 2021 New County Finds of Prohibited Eradicate Noxious Weeds

A noxious weed is defined by the Minnesota Noxious Weed Law as an annual, biennial, or perennial plant that the Commissioner of Agriculture designates to be injurious to public health, the environment, public roads, crops, livestock, or other property. Noxious weeds are categorized into four regulatory categories: Prohibited Eradicate, Prohibited Control, Restricted, and Specially Regulated. The highest priority weeds are Prohibited Eradicate. To prevent these species from becoming widespread throughout the state, the law states that all above and below ground plant parts of Prohibited Eradicate species must be destroyed.

Collaboration with multiple agencies, organizations, and private landowners throughout the state helps the Minnesota Department of Agriculture (MDA) successfully detect Prohibited Eradicate noxious weeds. In 2021, six Prohibited Eradicate species were confirmed for the first time in 14 counties.

Purchasing Seeds? Read the Label

All seed sold in Minnesota must be labeled with some key pieces of information whether it comes in a bag, a tote, or a packet. The process of labeling not only establishes what is in the container, but also what is not, such as prohibited noxious weed seeds like Palmer amaranth.

Seed labelers are responsible for having seed lots tested to ensure that noxious weed seeds are not present above acceptable levels and for determining the germination rate that can be expected of the seed. Seed labelers must maintain records and samples of tested seed lots to document that this process has occurred and that the information on the label is accurate.

While seed sold for agricultural use has more labeling requirements than seed sold for hobby use, both should have a test date or "sell by" date which is not expired.

Visit the MDA website to learn more about seed labeling requirements and how these are enforced by the MDA.
