Abstract/Contents: | Nine herbicides were evaluated for pre- and postemergence control of crabgrass, Digitaria ischaemum (Schreb.) Schreb. ex Muhl. in Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.). Preemergence materials used were DCPA (dimethyl tetrachloroterephthalate) 5G (16/30 and 24/48 mesh), 75W, and 6F; butralin [4-(1,1-dimethylethyl)-N-(1-methylpropyl)-2, 6-dinitrobenzenamine] 2.3G and 2.0G; prosulfalin (N-[[4-(dipropylamino)-3,5-dinitrophenyl]sulfonyl]-S,S-dime- thylsulfilimine) 50W; HOE-22870 (undisclosed) 2.5G; bensulide (O,O-diisopropylphosphorodithioate S-ester with N-(2-mercaptoethyl)benzenesulfonamide) 3.6G; benefin (N-butyl-N-ethyl-a,a,a-trifluoro-2,6-dinitro-3,4-xylidine) 2.5G. Chemicals which gave acceptable control (above 85%) of crabgrass in both turf species were DCPA (all formulations), prosulfalin, butralin (both formulations), bensulide, and siduron. The high rates of HOE-22870, benefin, and AC-92390 gave acceptable control in red fescue. Moderate injury was found on red fescue treated with DCPA (all formulations) and the high rates of butralin (2.3G) and benefin. Postemergence materials used were DSMA (disodium methanearsonate) 2.9G and HOE-22870 2.5G. The best postemergence control resulted from applications of DSMA, however, control from either material was not comparable to that obtained with preemergence materials. The high rate of HOE-22870 injured bluegrass severely. |
