pre-emergent
Stops seeds germinating
Pre-emergent describes herbicides applied before weed seeds germinate, creating a chemical barrier in the soil that prevents sprouting: Apply pre-emergent in early spring before crabgrass appears.
The term contrasts with post-emergent herbicides, which kill weeds already growing.
Timing is critical—once weeds have emerged, pre-emergent treatments are ineffective.
