Farmers, agronomists encouraged to check for invasive species

WINONA, Minn. (WKBT)– Now is the time to be checking around your farm for an invasive weed. This time of year is when Palmer amaranth is visible in agricultural fields, according to the Minnesota Department of Agriculture.

Palmer amaranth was first discovered in Winona County in July and in Houston County in September of 2019, according to the department.

A single female plant typically produces 100,000 to 500,000 seeds. It is resistant to multiple herbicides and all parts above and below ground must be destroyed.

It can cause substantial yield losses and greatly increase weed management costs in soybeans and corn.

The Minnesota Department of Agriculture is asking farmers and agronomists to pull out any plants and report them. You can report it to the ‘Arrest the Pest’ line at 1-888-545-6684 or
