Abstract/Contents:Several commercially available and experimental herbicides were evaluated for preemergence control of smooth crabgrass on an established Adelphi and Kenblue Kentucky bluegrass turf. In early April 1986 the plot area was vertically mowed to expose some surface soil and seeded with two pounds of smooth crabgrass (area was previously infested). The turf was mowed at a height of 1.5 inches and nitrogen was applied at 1 lb/1000 sq ft in May and June. The 27 treatments with 3 replications were applied to 6' x 10' plots. Treatments with repeat applications were re-sprayed on June 23. Treatments, formulation, application rate, and % control on 6 Aug and 2 Sept are provided in a table. Ronstar, Prodiamine, Betasan and Pendimethalin gave >97% control. Sonalan gave poor control.
