As restrictions on water use, fertilization, and pesticide applications continue to increase, golf course superintendents will need to use grass species that require reduced inputs. The objective of this study was to evaluate alternative turfgrass species under lowinput fairways conditions. In 2005, 17 species were established on native soil in St. Paul, MN. Each species was evaluated at three ...

Rationale The use of biological control organisms to augment chemical pesticide applications is gaining popularity amongst the environmentally conscious. While a moderate amount of information is known about the effect of pesticides on the indigenous ecology of a given environment, relatively little data exists describing the effect of introducing living organisms to a native community, especia...

climate-controlled greenhouse at the G.C.Horn turf field laboratory at the University of Florida in Gainesville. Floratam St.Augustinegrass is being compared with a mix of ornamentals including canna, nandina, ligustrum and allamanda. Plant material is growing in 80-gallon plastic pots in an Arredondo fine sand. There are three fertilizer treatments (16-4-8 quick-release, 15-0-15 quick-release,...

Evaluating ‘Champion’ Bermudagrass in the Field with Various Rates of Nitrogen, Trinexapac-ethyl (Primo), and a Granular Thatch Reducer (Thatch-X) Golf course putting green grasses normally receive stresses from increased traffic, low heights of cut, high potentials to pests due to weakened resistance, and frequent removal of clippings by losing viable food sources. Additionally, in the transit...

Root-knot nematodes (Meloidogyne spp.) are the most common and destructive plant-parasitic nematode group worldwide and adversely influence both crop quality and yield. In this study, a total of 51 root-knot nematode populations from turfgrasses were tested, of which 44 were from North Carolina, 6 from South Carolina and 1 from Virginia. Molecular characterisation was performed on these samples...

Rationale Biological organisms for the prevention of turfgrass diseases are now available and in widespread use. Biological control is achieved through antagonistic action of one organism toward another such as a pathogen or weed. At present, no genetically engineered organisms are available in the turfgrass industry, however, as advances in biotechnology increase the activity of wild type (nat...

Wetting agents can be used to increase infiltration rates into hydrophobic (water repellent) soils. A field test was conducted on a soil classified as Tujunga stony sandy loam, which was found to be extremely hydrophobic to learn more about the effectiveness of wetting agents. The area is located near Fontana. The land had been farmed in small grain crops years ago and then was used as a hog ra...

Maintaining high-quality athletic field playing surfaces without the use of synthetic pesticides is challenging. Little research available regarding best overseeding strategies for non-irrigated, pesticide-free, cool-season fields. The objectives this study were to determine effects turfgrass species, cultivar, seeding rate, and seasons on color, dark green color index (DGCI), cover, weeds, ove...
