Abstract/Contents: | In a glasshouse trial, mowing did not appear to reduce yellow nutsedge [Cyperus esculentus] shoot development, but did reduce root, rhizome and tuber development. When Kentucky bluegrass [Poa pratensis] was grown together with C. esculentus, shoot development as well as root, rhizome and tuber development were substantially decreased. In field studies, the density of C. esculentus in a Kentucky bluegrass turf decreased as the mowing height (in the range 0.75-3 in.) was raised and fertilizer rates (0.5-2 lb N/ft2 month) were increased. Among the herbicides evaluated post-em. in the summer, repeat applications of MAMA +- 2,4-D and bentazone or cyperquat gave excellent control, while single applications were fair. Severe phytotoxicity occurred with MAMA +- 2,4-D and cyperquat showed moderate injury to turf at 3 lb/acre. 2,4-D + dicamba or bentazone were non-injurious. |
