Herbicides are chemicals that control weeds and unwanted plants growing in areas of the garden where you don't want them. These chemicals come in different formulas and are almost as varied as the group of existing plants. Contact herbicides only kill the part of the plant with which they come in contact. Translocated herbicides travel through the plant from the point of application and kill it. Soil herbicides are incorporated into the soil to prevent weeds from developing.
Aim EW is a post-emergent contact herbicide that controls broadleaf weeds and suckers. It's effective when sprayed on developing plants no taller than 4 inches.

Its active chemical is carfentrazone-ethyl.
Finale is a glufosinate-based translocated herbicide. It's used in beds of cut flowers to prevent weeds and to kill those that germinate.
