| Abstract/Contents: | "This study was conducted on a mature stand of "Midnight" Kentucky bluegrass at the Landscape Management Research Center, Penn State University, University Park, Pa. The objective of the study was to evaluate the efficacy of herbicides for the preemergence control of smooth crabgrass. This study was a randomized complete block design with three replications. Treatments were applied on April 11, April 25 and April 27, 2001 (Barricade 4SL treatments were the only treatments applied on April 27, 2001) using a three foot CO2 powered boom sprayer calibrated to deliver 80 gpa using two, flat fan, 6504 nozzles at 40 psi. Some treatments were re-applied six weeks later on June 6, 2001. Granular treatments were applied with a shaker jar. After application the entire test site received approximately 0.5 inch of water. On April 27, 2001, 0.5 lb N/M was applied from urea and 0.5 lb N/M from a 24-4-12 SCU fertilizer to treatments that did not contain any nitrogen as a herbicide carrier. Crabgrass germination was first noted in the test site on April 27, 2001. Consequently, on April 27, 2001, Acclaim Extra 0.57 EW was applied to the entire test area at a rate of 20 oz/A. On May 5, 2001, Acclaim Extra 0.57EW was applied to only the Barricade 4SL treatments at a rate of 20 oz/A. Crabgrass pressure was rated as being sever [severe] in the study site, as infestation in the untreated plots was nearly 100%. Acceptable control was considered for ratings of 85% or greater. Acceptable control was achieved by the following herbicide treatments; Dimension 40WP at 0.5 lbs ai/A, Barricade 65 WDG at 0.75 and 1.0 lbs ai/A, Pendulum 3.3EC using a 6 week split application at 1.5 lbs ai/A each timing (total 3.0 lbs ai/A), Ronstar 0.95 (LESCO) at 3 lbs ai/A, Ronstar 2G at 3.0 lbs ai/A, Dimension 40WP at 0.25 lbs ai/A, and Betasan 4EC at 9.2 oz/M had control, at least, at the 83% level." |
