This can be accomplished through herbicide application, mechanical removal, etc.

Road construction and maintenance, including herbicide application, is a threat.

Manually pulling plants out of the ground supplemented by herbicide application is an effective but temporary control method.

Resprouts should be treated with a second herbicide application to the new growth.

Because of the long germination window for tall waterhemp, a single herbicide application is unlikely to be an effective control strategy.

In some cases, the clover could not be killed at the first herbicide application, so a second application was needed.

Dying plants have been observed at the highway's edge, a possible sign of herbicide application.

Reseeding may also be necessary after some herbicide applications so that beneficial native species remain plentiful.

The herbicide application should be done when weeds are quite young.

Mechanical cultivation and hand weeding were often necessary to control weeds not controlled by herbicide applications.
