Palmer Amaranth is a high-impact agronomic weed species that has cost the United States agriculture industry billions of dollars since its discovery outside of its native range in the southwestern U.S. and northwestern Mexico. Over the last 20 years, it has moved further north, and now poses a major threat to corn, soybean, and cotton growers across the south and Midwest regions of the United States.
It is not legal to sell any kind of seed in Minnesota if the seed lot contains Palmer Amaranth. The problem is this particular invasive species which has shown potential to wipe out up to 91% of corn yields, 68% of soybean yields, and 54% of cotton yields is difficult to visibly distinguish from other pigweed species, making identification reliant upon genetic testing.
U of M researchers develop 99 9% accurate genetic test for early detection of Palmer Amaranth

Spring was exploding all along the St. Louis River estuary on a sunny, warm afternoon early this week.
Recently arrived Canada geese were honking madly at one another, vying for nesting areas. Trumpeter swans and mallards were back, too. Songbirds, chickadees mostly, were singing. Ring-billed gulls were making noise.
NORTH ST. LOUIS COUNTY â Seven hundred youth tested their knowledge in animal science and wildlife-related topics during competitive 4-H events throughout March.
This March, 700 youth on 171 teams from across Minnesota participated in the 4-H Project Bowl, the second largest 4-H event series of the year. 4-H Project Bowl challenges teams of three to five youth to test their knowledge on a variety of topics including dairy, dog, general livestock, horse, llama/alpaca, poultry, rabbit and wildlife conservation.
Competitions were held virtually with divisions for both junior and senior aged teams. This year, teams worked together to answer species related questions in a trivia format. Top placing teams in dairy, general livestock, horse and poultry hope to go on to national project bowl competitions.
