Preemergence herbicides are used to stop growth of:

Explanation:
Preemergence herbicides are applied before weeds emerge and work by preventing the weed seeds from germinating or stopping the very early growth of seedlings as soon as they begin to sprout in the soil. They form a chemical barrier in the top layer of soil, so the first signs of life from the seed are suppressed. Because their action targets seeds and the initial seedling stage, they don’t affect weeds that are already mature, nor do they control insects or fungal spores. This makes seed germination the precise stage these products are designed to disrupt.
