A weed control method that involves manual removal

A herbicide that prevents weed seeds from germinating

A 'pre-emergent' herbicide refers to a specific type of weed control product that is designed to be applied to the soil before the weeds have the chance to germinate. Its primary function is to inhibit the growth of weed seeds as they begin to sprout. By creating a chemical barrier in the soil, these herbicides can effectively prevent a wide variety of weed species from establishing themselves, thus maintaining a healthier and more productive environment for desired plants or crops.

This capability is particularly valuable in agriculture and landscaping, where controlling weed populations can significantly influence the health of crops and the aesthetics of gardens or lawns. Pre-emergent herbicides must be applied at the correct time, usually before weed seeds begin to germinate, to ensure their effectiveness.
