Knotroot Foxtail Demonstration
Location: Baxter, Benton, Cleburne, Crawford, Faulkner, Franklin, Hot Springs, Johnson, Marion, Madison, Newton, Perry, Scott, Stone, Washington and Yell Counties, Arkansas
Knotroot foxtail is an invasive perennial summer grass weed that has low forage quality. The foxtail seed head emerges in July, so most producers don’t recognize the infestation problem until late in the growing season. In recent years it has become a concern to forage producers throughout Arkansas.
Forage producers have limited herbicide options for grass control in forage grass
crops. The objective for this demonstration was to compare the effectiveness of grass
herbicides, non-selective herbicides, and combinations of both for knotroot foxtail
control in forage grasses. Read the rest of the demonstration in the PDF below.

these troublesome grassy weeds. To learn more and see the demonstration results, view
