Prosapia bicincta (Say) (Hemiptera: Cercopidae), the twolined spittlebug, is an economic pest of turfgrass in the southeastern United States. No data concerning natural enemies of P. bicincta in turfgrass have been reported previously. We compared predation of spittlebug eggs, nymphs, and adults in the laboratory by potential generalist predators commonly found in turfgrass: bigeyed bugs Geocor...

Leaf and sheath spot (mini ring) is a turfgrass fungal disease that has been reported in some states the USA. The causal pathogen Waitea circinata var. zeae, also known as Rhizoctonia zeae. This typically causes thinned turf areas and/or rings of full, half, or quarter circles. Turfgrass under stress irrigated with high salinity water more prone to infestation. Seven fungicide programs were eva...

Abstract This study investigated the effect of compost tea applications on turf quality and soil microbial activity. Evaluations turfgrass were based The National Turfgrass Evaluation Program's guidelines while samples analyzed for chemical attributes Four sites treatments included: 1) a drench application with irrigation, 2) no 3) 4) nor irrigation. Fifteen observations from each treatment col...

California is suffering from a serious drought and the future of turfgrass and other landscape plants has never been more uncertain. Use of drought tolerant plant species should be at the forefront of water conservation management plans for golf courses and other landscapes. Warm-season or C4 grasses are better adapted to warmer, drier climates and use at least 20% less water compared to cool-s...

Phosphorus losses from turfgrass areas are perceived to contribute to water quality problems, yet a comprehensive review of P fate in turfgrass ecosystems is lacking. According to available data in the literature, phosphorus fertilizer inputs (2–10 kg ha–1) slightly exceed the estimated outputs of phosphorus in clippings (0.4–7.5 kg ha–1). Sediment losses from turf areas are negligible, general...

Water conservation is a priority in San Antonio, Austin, Dallas, and other major Texas cities that routinely face water shortages and drought. Soil management is fundamental to water conservation efforts. Incorporation of composted biosolids (CB) in low quality soils can enhance water conservation and provide organic carbon and nutrients that improve growth of vegetation and limit sediment loss...

An Ultra-Low Volume (ULV) sprayer was developed to decrease carrier volume required for pesticide applications in row and turfgrass cropping systems. The ULV sprayer can make spray applications at or below 19 L ha-1 , which is far lower than a conventional sprayer in row crop or turfgrass production systems. Field studies were Facility near Mead, NE to compare the ULV sprayer to a conventional ...

Transition of populations from rural to urban living causes landscape changes and alters the functionality of soil ecosystems. It is unclear how this urbanization disturbs the microbial ecology of soils and how the disruption influences nitrogen cycling. In this study, microbial communities in turfgrass-grown soils from urban and suburban areas around Xiamen City were compared to microbial comm...

Bioassays using pellets of agar, thatch-agar and turfgrass-agar were developed using benzimidazole-sensitive Penicillium expansum, to detect the fungicide methyl 2-benzimidazole carbamate (MBC) which is the major fungitoxic degradation product of benomyl [methyl 1-(butylcarbamoyl)-2-benzimidazole carbamate] in thatch and turfgrass clippings. These bioassays were used to estimate the amount of f...

Pesticide usage on public school grounds is a concern in the U.S. Pacific Northwest. Our objective was to determine how variations primary cultural management practices (mowing, fertilization, and irrigation), absence of herbicide applications, can affect turfgrass quality, weed populations. Three experiments were conducted over three years at OSU Lewis-Brown Horticulture Farm Corvallis, OR mix...
