Pre-emergent Herbicide

Definition:

Pre-emergent Herbicide

A form of weed control that kills plants as they germinate, prior to the plant’s emergence into the environment. Pre-emergent herbicides are applied during initial lawn care to prevent weeds and unwanted plants from growing. Application depends on the weed's growth period. It is generally recommended to apply pre-emergent herbicides for summer weeds in the spring, and during fall for winter weeds.
