Why Is It a Noxious Weed?

Lepyrodiclis infests grain and pea fields where it grows up and over crops forming a canopy that shades crops from the sun. Lepyrodiclis was changed from a Class B to a Class C noxious weed in 2013.

How would I identify it?

How Do I Control It?

General Control Strategy

Treatment should extend at least 20 feet beyond the boundary of observed plants to lessen the chance that additional plants establish from stray seed.

Mechanical Control

Small patches may be pulled and bagged. Tillage can be used to kill lepyrodiclis for patches too large for hand removal.

Cultural Control

Grass competition may help suppress it.

Herbicide Control

Please refer to the PNW Weed Management Handbook, or contact your county noxious weed coordinator.
