... Fairy ring is the common name for a complex disease of turf encompassing the appearance of mushrooms, circles of stimulated grass, or rings of damaged or dead turfgrass maintained for lawns, athletic fields, or golf courses. Type-I fairy ring is especially destructive due to the development...

... The turfgrass program at Michigan State University has recently dedicated and focused its research on sports turf management. There are three major areas of research: (1) the indoor turfgrass project, (2) the use of crumb rubber from used tires, and (3) management of high sand-based root zone...

... movement is measured at various degrees of rotation or linear distance traveled. Experiments were conducted to determine the effect of turfgrass and soil conditions on traction of turf areas. Specifically, the influences of species, cutting height, shoe type, and loading weight on traction were determined...

... bounce and speed, and sliding surface properties. Various methods are available for objective assessment of hardness, traction, and ball responses, and they should be used to assess a range of turfed and skinned areas. The quality of the playing surface is greatly affected by soil properties, turfgrass...

... Surface application of insecticides on turfgrass for control of many subsurface grubs is not very efficient. It can be potentially hazardous to people, pets and other animals exposed to the insecticides. To reduce this danger, three injection systems were developed to place insecticides below...

.... After a series of experiments that evaluated the effects of turfgrass management practices on impact absorption characteristics, correlation coefficients between impact characteristics and between impact hammers were deter-mined. The correlation between the impact characteristics was higher when...

... In recent years, interest in plant growth retardants (PGRs) for use on turfgrass has been very high. This interest has occurred because of the availability of some new experimental compounds, increases in fuel and labor rates, and the desire for people to have more recreation time. In the past...
