How do broadleaf herbicides work?

Broadleaf herbicides are absorbed by the weed’s foliage, not its roots. To be effective, the granules must stick to the weeds and the herbicide absorbed by the weed’s foliage. Apply granular products in the early morning when the foliage is wet with dew or irrigate the lawn prior to the application.

How do you use herbicides?

Selective herbicides can be further divided into pre-emergent and post-emergent herbicides.

  2. Post-emergent herbicides are usually applied to the foliage where they are absorbed into the plant tissue.

Selective herbicides kill only certain weeds, while nonselective herbicides kill any green, growing plant, whether it’s a weed or not.
