The Minnesota Department of Agriculture is considering several possible pathways as it investigates the latest detection of Palmer amaranth.
Denise Thiede with MDA says the invasive weed was most recently identified in Goodhue County in southeastern Minnesota.
“Seed and screenings have been the two common pathways. Manure when screenings are being used as feed (is) also a common pathway. Right now we’re considering all of those potential pathways in this Goodhue County case.”
Palmer has now been confirmed in 12 Minnesota counties since first being discovered in the state five years ago.
