| Abstract/Contents: | Presents the 2000 results of a study "to determine the effectiveness of commercially available and experimental preemergence herbicides to control crabgrass." Results include "none of the herbicide treatments caused phytotoxicity to the Kentucky bluegrass turf rated on 3, 7, and 10 days after application. The crabgrass population on the experimental site was extremely high. Percent cover by crabgrass in the check plot was 76.7% on 3 August and 100% on 8 Sep. Due to the high crabgrass population only three herbicide treatments provided less than 30% crabgrass cover on 8 Sep. Since crabgrass cover on all plots was so high on 8 Sep, data from the 3 Aug rating date will be discussed. Herbicide treatments providing 15% or less crabgrass cover were considered to have provided commercially acceptable control. Treatments providing 15% or less crabgrass cover were: Team Pro on 19-3-7 0.86G applied 1.5 lbs ai/A 0 and 45 days, A12333C 4L applied 1.0 lbs ai/A 0 days, Barricade 65WG applied 1.0 lbs ai/A 0 days, A12333B 4L applied 1.0 lbs ai/A 0 days, Barricade 65WG applied 0.75 lbs ai/A 0 days, and A12333C 4L applied 0.75 lbs ai/A 0 days. Several other treatments provided nearly 15% or less crabgrass cover and were not statistically different from teratments that provided 15% or less crabgrass cover. Herbicide treatments that provided the least crabgrass cover wer those treatments applied as a split application or at higher rates." |
