The purpose of pre-emergent herbicides is to prevent weed seeds from germinating. These herbicides work by creating a chemical barrier in the soil that targets seeds before they have the opportunity to sprout. They are typically applied before the time of year when weeds are expected to emerge, providing an effective strategy to control weed populations in lawns, gardens, and agricultural fields.

By using pre-emergent herbicides, applicators can significantly reduce the number of weed seedlings that establish in their desired planting areas, thereby helping to maintain the health and productivity of crops or landscape plants. This proactive approach is particularly important in managing troublesome weed species that could compete with crops for nutrients, water, and sunlight once they emerge.

The other choices relate to different functions that herbicides or agricultural practices might serve, but they do not accurately describe the specific role of pre-emergent herbicides. For instance, killing established weeds pertains to post-emergent herbicides, which are designed to target and eliminate weeds that have already germinated and are actively growing. Promoting crop growth and enhancing soil fertility are goals of various agricultural practices and soil amendments, but they are not in the direct scope of what pre-emergent herbicides are designed to do.
