ALS Inhibitors. ALS Inhibitors are a family of herbicides. Herbicides that inhibit acetolactate synthase (ALS), the enzyme common to the biosynthesis of the branch-chain amino acids (valine, leucine, and isoleucine), affect many species of higher plants as well as bacteria, fungi, yeasts, and algae.
Pre-emergent Herbicides for Crabgrass Prevention in Lawns. Pre-emergent herbicides are most effective at controlling annual grassy weeds like crabgrass, foxtail, goose grass, and barnyard grass. Fair control of annual broadleaf weeds such as purslane, spurge, and oxalis can be expected from most pre-emergents.
