Plots were established in 1971 to determine the effect of herbicides on stands of green sagewort (Artemisia campestris L.). Treatments were applied in 1971, 1972, and 1973 for one study and in 1972 and 1973 for another study. Visual estimates of green sagewort control were made in 1971, 1972, 1973, and 1974. Repeat applications of 2,4-D ester at 2.24 or 3.36 kg/ha effectively controlled green sagewort whether applied in 2 or 3 consecutive years. Dicamba or picloram, each in combination with 2,4-D ester, also effectively reduced the stand of green sagewort. Green sagewort was not controlled effectively by 2,4-D ester alone at rates less than 2.24 kg/ha or 2,4,5-T at rates of 1.12 or 2.24 kg/ha. Picloram, when applied alone, was not as effective as in combination with 2,4-D ester. Retreatment is necessary when attempting to control green sagewort. Two consecutive annual application of 2,4-D ester effectively reduced the stand. After reducing the stand of green sagewort, spraying every 2nd or 3rd year as a maintenance program may be adequate to keep populations of green sagewort plants at a minimum.
