Yields of forage were measured 3 to 5 years after the use of 2,4-D, 2,4-D + 2,4,5-T, and picloram + 2,4-D applied at brush control rates. The yield of bromegrass and alfalfa on the herbicide treated areas was either reduced or remained unchanged. This occurred because alfalfa can not tolerate the high herbicide rates required for brush control. On an area which never received a herbicide treatment, alfalfa was unable to compete with invading aspen poplar and prickly rose. Ranchers should use herbicides to prevent secondary succession from grasslands to the aspen poplar vegetation type which has a low amount of forage available for cattle. Arguments are presented for including alfalfa in a seeding program when a mixture of 2,4-D + picloram is used for brush control but not when a mixture of 2,4-D + 2,4,5-T is used.
