Abstract/Contents: | Preemergence and postemergence herbicides were evaluated for the control of annual bluegrass in Kentucky bluegrass lawn areas. Effectiveness of treatments was based on degree of turf discoloration and changes in annual and Kentucky bluegrass cover. After four years use of preemergence herbicides, none of which caused objectionable discoloration, the most effective material was bensulide (91% control) followed by butralin (85%), prosulfalin (83%), benefin (59%), H-22234 (37%), DCPA (36%), oxadiazon (29%) and siduron (19%). With most postemergence herbicide treatments there was a decrease in annual bluegrass and an increase in Kentucky bluegrass. However, the elimination of annual bluegrass usually resulted in overall turf discoloration and thin, open turf. The most promising treatments were diuron at .5 lb, endothall spray at 2 lb, endothall granular at 6 lb, linuron granular at 3 lb and terbacil at .25 lb. Higher rates of diuron and terbacil caused a decrease in both annual and Kentucky bluegrass while the use of MH + CF was ineffective. A good approach to the control of annual bluegrass would be to use repeated postemergent herbicide treatments at low rates coupled with techniques to increase Kentucky bluegrass cover. |
