Annual clovers are seeded following brush removal in many range improvement programs in California. In the growing season following brush removal, brush seeds germinate, and old brush roots and crowns sprout. These seedlings and sprouts can be destroyed readily by 2,4-dichlorophenoxyacetic acid—2,4-D—sprays if they are applied soon after emergence. Such applications are most effective in the spring when growth is rapid. Unfortunately, at that time the seeded clovers are also susceptible to injury by 2,4-D.
