Colletotrichum cereale is an ascomycete inhabitant of cool-season Pooideae grasses. The fungus has increased in frequency over the past decade as a destructive pathogen of Poa annua and Agrostis stolonifera turfgrass. Colletotrichum cereale exists as two lineages, designated clades A and B, but little is known about the distribution of these clades in natural environments, or what role these su...

Abstract Turfgrass with sand‐based root zones, such as golf course putting greens, are highly important economically and require intense management. However, problems often associated low nutrient retention limited microbial activity. Soil additives may increase soil biological activity, improve nitrogen (N) cycling efficiency, thus reduce fertilizer N inputs. A 2‐yr experiment was conducted on...

2,4-dimethylamine salt (2,4-D) is an herbicide commonly applied on athletic fields for broadleaf weed control that can dislodge from treated turfgrass. Dislodge potential is affected by numerous factors, including turfgrass canopy conditions. Building on previous research confirming herbicide-turfgrass dynamics can vary widely between species, field research was initiated in 2014 and 2015 in Ra...

The extent of root, rhizome, and/or stolon growth determines turfgrass sod maturity. In 1998, at Michigan State University, the Calrochan Sod Puller (CSP) was developed to measure the force necessary to tear a piece of sod. The CSP uses a battery powered hydraulic pulley to provide a consistent pulling force, and is attached to a load cell. In August 1999, sod strength measurements of different...

Soil pH may influence speciation and extractability of Pb, depending on type of vegetation in urban soil environments. We investigated the relationship between soil pH and Pb extractability at forest and turf grass sites in Baltimore, Maryland. Our two hypotheses were: (1) due to lower pH values in forest soils, more Pb will be in exchangeable forms in forested than in turfgrass soils and (2) d...

drought stress is one of the phenomena that adversely affects growth and quality of plants, with turfgrass being no exception. for a study of the responses of poa pratensis l. cv. ’barimpala‘ to time periods of drought stress, turfgrass seeds were cultivated at 60cm depths in cylindrical pots of 15cm diameters and placed outdoors. plants were daily irrigated to the point until drainage occurred...

A 2-year greenhouse study was conducted at Clemson University, Clemson, S.C., in 2003 and 2004 to determine drought responses of six bermudagrass (Cynodon spp.) cultivars at four irrigation intervals. Cultivars selected from the 2002 National Turfgrass Evaluation Program Bermudagrass Trial were ‘SWI-1012’, ‘Arizona Common’, ‘Tift No.3’, ‘Tifsport’, ‘Aussie Green’, and ‘Celebration’. Treatments ...
