Alligatorweed is actually a aquatic weed and normally only found on over watered lawns. Mowing actually spreads Alligatorweed by vegetative propagation. Recommend Aquatic chemical suppression include Glyphosate and 2,4-D which is one the herbicides in 3 Way. However Triclopyr is listed as a control. Once the Alligatorweed hits land 2,4-D will control it. Remember Alligatorweed grows as a Emersed plant or under water but does break the surface.
