How to control spikeweed

I would like more information on the area to be treated to make sure it is on the herbicide label and what types of native grasses are present before making a recommendation of cultural, mechanical, or chemical treatment.

Thank you.

The Spike-weed is in fields of Sandburg blue grass and Idaho fescue.
We also have starting along trails.
We have been pulling and bagging it, but some areas have large plots that need broadcast treaments.

Thank you,

Please contact me at 509-524-2685. I would like to discuss this situation directly because this weed is not easily controlled by herbicide and the herbicides may be restricted and may damage trees and shrubs.

Thank you.
