How Do Weed Killers Kill Weeds and Not Lawns?
Herbicides are complicated chemicals and the way they work depends largely on the type being used. There are two primary types of herbicides or weed killers – pre-emergence and post-emergence. Pre-emergence herbicides kill plant life while the seed is germinating, while post-emergence herbicides kill weeds during active growth. Both types of weed killer can be selective or nonselective, which is the reason certain weed killers kill weeds but not lawns. An easier explanation of how weed killers kill weeds without killing lawns is to understand what weeds are. Weeds are simply plant life growing in an undesirable place. In other words, what may be considered a weed in one location is considered a plant in another. Herbicides are applied to kill weeds when they are growing in an undesirable location. By using a selective herbicide that targets broadleaf plants, for example, weeds can be killed without harming most grasses. The science behind how herbicides kill weeds is linked to cell gro
