| Abstract/Contents: | "The first study was conducted on a mature stand of perennial ryegrass (Lolium perenne L) at the Valentine Turfgrass Research Center, Penn State Univ., Univ. Park, PA. The test site was mowed at one inch and irrigated to prevent wilt. The objective of the study was to determine the efficacy of selected broadleaf herbicides for the control of dandelion (Taraxacum officinale), common plantain (Plantago major), and white clover (Trifolum repens). This study was a randomized complete block design with three replications. replications. All of the treatments were applied on June 7, 2002 using a three foot C2 powered boom sprayer calibrated to deliver 80 gpa using, two flat fan, 11004 nozzles at 40 psi. The individual plot size was 30 square feet. With regard to the control of dandelion, white clover, and common plantain in the perennial ryegrass trial, all the control of dandelion was highly variable across the treatments. However, the control of dandelion was highly variable across the treatments. For example, on the July 16 rating date, no treatment controlled dandelion better than 63.9%. By the July 29 rating date, only the Speed Zone at the low rate and Speed Zone St. Augustine at the low rate had relatively poor dandelion control compared to the rest of the treatments. The second study was conducted on a matured mixed stand of perennial ryegrass (Lolium perenne L.), Kentucky bluegrass (Poa pratensis) and fine fescue (Festuca spp.) on a home lawn in Julian, PA. The objective of the study was to determine the efficacy of broadleaf weed herbicides for the control of ground ivy (Glechoma henderacea). Although there were many types of broadleaf weeds in the stand they were not uniform enough to evaluate control on a species by species basis. The term 'other weed' (used in this abstract) thus refers to buckhorn plantain (Plantago lanceolata), common plantain, dog fennel (Anthemis cotula), slender speedwell (Veronica serpyllifolia), wild violet (Viola supp.), wild strawberry (Fragaria virginiana), yellow woodsorrel (Oxalis strica), white clover, dandelion, yellow hawkseed ( Hieracium pretense), mouse ear chickweed (Cerastium vulgatum), thymeleaf speedwell (Veronica serpyllifolia), healall (Prunella vulgaris), wild carrot (Daucus carota), and yarrow (Achillea millefolium) that were present at the time of the herbicide application. The study was a randomized complete block design with three replications. All of the treatments were applied on June 10, 2002 using a three foot C2 powered boom sprayer calibrated to deliver 40 gpa using two, flat fan, 11004 nozzles at 40 psi. Ratings were taken on June 10, July 8, Aug 5, 2002. Each plot was rated for ground ivy cover and other weed cover prior to treatment. The site was mowed at two inches with a rotary mower with clippings returned. The site was not irrigated. Ground ivy control was highly variable from treatment to treatment. Sprayed formulations provided better control than granular materials. Speed Zone, Drive plus 2,4-D and MSO, Confront and Trimec Classic tended to provide the best and most lasting control of ground ivy. Control of the other weeds on the site was also variable, but the sprayed formulations again were typically more efficacious than the granular formulations. |
