Leafy Spurge

Euphorbia esula

Milky sap that irritates skin and blisters mouths, so livestock and wildlife leave it alone and it displaces the forage around it. Roots run deep enough that mechanical control rarely finishes the job.

What we know

Class 2: control

Established in varying populations statewide, at a concentration where control or eradication may still be possible. High priority.

Treatment on leafy spurge works best may - jul. A full profile for this species is still being written. Until it is here, the USU Extension field guide carries identification detail, and we would rather hear from you than have you guess.
