| Abstract/Contents: | Trials were established in 1982 and 1983 to evaluate standard and experimental preemergent chemicals, alone and in combination, for the control of smooth crabgrass [Digitaria ischaemon (Schreb.) Muhl.] and prostrate spurge ( Euphorbia supina Raf.). The 1982 trial was conducted in red fescue turf while lawn areas used for 1983 herbicide evaluations included uniform stands of Kentucky bluegrass and perennial ryegrass and a predominately red fescue area containing some Kentucky bluegrass. The tolerance of these cool season turfgrasses to selected preemergent herbicides was also observed. Crabgrass pressure for the 1983 test year was considered very heavy, ranging from 5 to 12 times that of the 1982 tests. Effectiveness of treatment was based on percent crabgrass and spurge control and turfgrass injury. In 1982 with the exception of S734, all herbicides tested at all rates and in all formulations provided excellent control of crabgrass in red fescue turf. In 1983 greatest crabgrass control in all grasses was realized with butralin, DCPA, or pendimethalin while control was inadequate where K1441, KIH-3356 or napropamide were used. In Kentucky bluegrass areas, adequate control was achieved with bensulide and oxadiazon, while these chemicals were not as effective in controlling crabgrass in perennial ryegrass or red fescue lawns. In 1982, however, bensulide and oxadiazon had provided excellent crabgrass control at all rates for most formulations tested. The greatest control of spurge in Kentucky bluegrass lawns was achieved with butralin, DCPA, UC-77892, pendimethalin or a combination of DCPA, MSMA, 2,4-D and mecoprop. Most herbicides tested resulted in little or no turfgrass injury. Objectionable levels of injury were observed with oxadiazon in 1982 fescue trials and with UC-77892 in 1983 perennial ryegrass areas. The growth retardants EL-500 and PP-333 provided no effective control of crabgrass in red fescue turf. Increasing rates of chemicals generally did improve crabgrass or spurge control. Split applications of the same or different rates made in May and June 1983 resulted in greater control by most chemicals, and in many cases, the split application resulted in the only acceptable level of control shown by those chemicals. |
