Absinth wormwood is a statewide noxious weed that inhabits cropland, pasture, rangeland, right-of-ways, and waste sites.
If not effectively managed, the species can displace desirable vegetation, reduce crop yield and decrease land value. Absinth wormwood should be treated with herbicide in June to early July.
Once plants start showing a white powdery appearance on the leaves, herbicide effectiveness decreases drastically (Figure 1).
