(St. Paul, MN) — The Minnesota Department of Agriculture is confirming Japanese apple rust in the state for the first time.
The tree disease is caused by a fungal plant pathogen and affects apples, crabapples and junipers.
M-D-A staff discovered the fungus through recent surveys and routine inspections at orchards and nurseries in Dakota, Rice and Scott counties.
M-D-A officials say Japanese apple rust on the East Coast has not significantly impacted apple production. It was confirmed last year in Wisconsin.
