Abstract/Contents: | Experiments were conducted on established turfgrasses to assess commercial and experimental herbicides for preemergence control of smooth crabgrass (Digitaria ischaemum {Schreb.} Muhl.). In both 1979 and 1980, the efficacy of different rates and formulations were assessed by rating control and injury. In the 1979 experiment using 90% control as being acceptable, both rates of prosulfalin and pendimethalin, the high rate of disuron (13.44 kg/ha), both formulations of DCPA at 11.76 kg/ha, and one source of benefin at 2.24 kg/ha provided acceptable control in Kentucky bluegrass (Poa pratensis L.). None of the treatments caused significant injury to Kentucky bluegrass. All treatments except the 5.6 and 6.72 kg/ha rates of bensulide (4E) provided acceptable control of smooth crabgrass in creeping red fescue turf. Both formulations of DCPA (11.76 kg/ha), pendimethalin (2.24 and 3.36 kg/ha), and benefin (2.24 kg/ha) provided acceptable control. Alachlor, bensulide 4E, 3.6g, and in combination with napropamide or on a 10-6-4 fertilizer, and the 20/60 sieve size benefin did not provide greater than 90% control. As in 1979, none of the herbicide treatments caused injury to Kentucky bluegrass. Benefin, DCPA, prosulfalin, pendimethalin, and bensulide plus napropamide combination (5.60 + 2.24 kg/ha) provided acceptable control in creeping red fescur. Both formulation of DCPA, benefin, and the high rate of alachlor (6.72 kg/ha) caused injury to the fine fescue. The severity caused by DCPA and benefin was not as great as in 1979. During both years, the wettable formulation of DCPA caused more injury than the granular. The granular formulation of bensulide provided less control at all rates in 1980 compared to 1979. |
