Abstract/Contents:Postemergence herbicides and application methods were evaluated on several turfgrass species and two weeds in 1976. Selective control of smooth crabgrass {Digitaria ischaemum (Schreb.) Muhl.} was obtained with DSMA (disodium methanearsonate), MSMA (monoammonium methanearsonate), and HOE-22870 (unknown) while results with M-4212 (unknown, DOWCO 356) appear limited because of grass injury. Promising results for nutsedge (Cyperus esculentus L.) control were provided by certain treatments of bentazon {3-isopropyl -1H-2,1,3-benzothiadiazin-(4) 3H-one 2,2-dioxide}, cyperquat (1-methyl-4-phenylpyridinium), DSMA, and perfluidone {1,1,1-trifluoro-N-{2-methyl-4-(Phenylsulfonyl)phenyl} methane-sulfonamide}. Nutsedge control was easier to achieve with midsummer rates than late spring treatment. Comparable nutsedge control and Kentucky bluegrass (Poa pratensis L.) tolerance was obtained with sprayer and hose proportioner. Mowing had little effect on nutsedge control. Mowing one hour before spraying resulted in greater injury to Kentucky bluegrass compared to mowing one hour after treatment. Increasing the spray volume of DSMA reduced bluegrass injury. 'Merion' Kentucky bluegrass, 'Jamestown' red fescue ( Festuca rubra L.), 'Exeter' colonial bentgrass ( Agrostis tenuis Sibth.), and 'Penncross' creeping bentgrass (Agrostis palustris Huds.) were all tolerant to bentazon. Bluegrass and fescue were more tolerant than other grasses to cyperquat and HOE-22870 while with DSMA, Kentucky bluegrass was the most tolerant. 'Manhattan' perennial ryegrass (Lolium perenne L.) showed little tolerance to HOE-22870.
