Abstract/Contents: | "An experiment was conducted to evaluate the control of smooth crabgrass (Digitaria ischaemum (Schreb.) Muhl.) with selected herbicides and their combinations at the Landscape Management Research Center of the Penn State University, University Park, PA. Treatments were arranged in a complete randomized block design with three replications on a mixed stand of cool season grasses. Spray treatments were applied with a 3', CO2 powered boom sprayer, delivering 75 gal/A with two T-jet 6504 nozzles, on May 7, 1991. Granular treatments were combined with sand and applied with a shaker jar on May 7, 1991. Plots were rated August 27, 1991. Acceptable control was considered to be 80% or higher. Due to the drought, the crabgrass population in the experimental site was highly variable and all treatments provided acceptable control." |
