BISMARCK – A workshop has been scheduled in Langdon to help weed control officials and land managers learn how to identify and control yellow toadflax.

Sponsored by the North Dakota Department of Agriculture (NDDA) and the Cavalier County Weed Board will be held from 11 a.m. to 1 p.m., Wednesday, Aug. 31, at the North Dakota State University Langdon Extension Center, 9280 107th Ave. NE, one mile east of Langdon on N.D. Highway 5.

“Yellow toadflax has become a serious problem in many parts of the country and it is quickly spreading in North Dakota,” said Agriculture Commissioner Doug Goehring, who declared yellow toadflax a noxious weed last year.

Goehring said he hoped weed control officers and land managers would take advantage of the free workshop.

The number of acres reported to be infested with yellow toadflax increased more than 50 percent from 2008 to 2009 and more than 500 percent from 2009 to 2010,” he said. “The weed can be controlled, but it is very difficult to eradicate.”

NDDA noxious weed staff and NDSU weed scientists will conduct the workshops.

A member of the snapdragon family, yellow toadflax (Linaria vulgaris) is native to southeastern Europe and southwestern Asia. Imported to this country as an ornamental, it was found in North Dakota as early as 1891. It is also known as butter-and-eggs, wild snapdragon, common toadflax, ramsted, flaxweed and Jacob's ladder.
