Utah State University Evaluation Of Ring To Green Final Research Report, Kelly Kopp, Paul Harris

CWEL Publications

Necrotic ring spot (Ophiosphaerella korrae) is the most commonly diagnosed fungal turfgrass disease by the Utah State University Plant Pest Diagnostic Laboratory. The disease effects coolseason grasses in the state and region, particularly Kentucky bluegrass. The necrotic ring spot (NRS) disease pathogen infects and kills turfgrass roots and crowns, resulting in the blighted appearance of turf amidst an otherwise healthy area of turf

In the late summer/fall of 2015, Utah State University (USU) began a research study of the Ring to GREEN product by GreenMaster Distributing, LLC for the control of necrotic ring spot in turfgrass. Prior to USU’s involvement, …

Growth Of Bella Bluegrass Compared To A Standard Kbg Blend And Tall Fescue, Paul Johnson, Xin Dai, Roberrto Gurel

CWEL Publications

A goal of low-input turfgrass is to reduce mowing, thereby reducing labor, fuel, and equipment expenses. A way to meet this goal is to develop grasses that grow slower. 'Bella' Kentucky bluegrass was released by the University of Nebraska-Lincoln as a slow-growing variety of bluegrass. This experiment documents slightly to significantly slower growth of 'Bella' compared to a traditional Kentucky bluegrass sod blend and tall fescue grown in the Intermountain West region of North America. Consumers frequently seek grasses that need less mowing and fertilizer (Busey and Parker, 1992). Although turfgrasses recover from traffic by growing, many uses don't need …

Phenotypic And Genotypic Analysis Of A U.S. Native Fine-Leaved Festuca Population Reveals Its Potential Use For Low-Input Urban Landscapes, Jack E. Staub, Matthew D. Robbins, Yingmei Ma, Paul Johnson

CWEL Publications

Continued reduction in limited natural resources worldwide increasingly necessitates the incorporation of low-maintenance and low-input plant materials into urban landscapes. Some fine-leaved Festuca grass species have been used in formal gardens and native urban landscapes because of their inherent tolerance to abiotic stresses, but native, ornamental types (tall and non-spreading with multicolored culms and panicles) are not common in landscapes of the western United States. A native fine-leaved Festuca collection made in Montana (designated FEID 9025897) by the U.S. Natural Resources Conservation Services possesses such ornamental characteristics but has not been evaluated for its horticultural potential. Therefore, a study was …

A Survey Of Apomixis And Ploidy Levels Among Poa L. (Poaceae) Using Flow Cytometry, Alicia Michelle Kelley, Paul G. Johnson, Blair L. Waldron, Michael D. Peel

CWEL Publications

Poa is a complex genus taxonomically and genetically. As a result, relatively little information exists for this economically important genus with regards to reproductive mode and variability in chromosome number. We examined apomixis frequency and ploidy levels in 83 Poa accessions representing 33 species from the National Plant Germplasm System using flow cytometric techniques. In reproductive mode analysis, we analyzed at least three preparations of 50 seeds each from the accessions. In ploidy level analysis, at least three plants of each accession were analyzed. Sixty percent of the species had at least one apomictic or facultative apomictic accession; 40% were …
