preemergent
Stops seeds germinating
Preemergent describes herbicides applied before weed seeds germinate, creating a chemical barrier in the soil that prevents sprouting: Apply preemergent in early spring before crabgrass takes hold.
The term contrasts with postemergent herbicides, which target weeds already growing.
Lawn care and agriculture rely heavily on preemergent treatments for weed prevention rather than elimination.
