A test chamber was projected and built (according to ISO 16000-9 Standard) to simulate atmospheric conditions experienced by rubber infill (when applied in synthetic turf pitches) and measure accurately the airborne emissions of pollutants such as dusts and volatile organic compounds (VOC), as well as pollutants present in leachates. It should be pointed out that standard ISO 16000-9 is only co...

Plant-parasitic nematodes can be very damaging to turfgrasses. The projected cancellation of the registration for fenamiphos in the near future has generated a great deal of interest in identifying acceptable alternative nematode management tactics for use on turfgrasses. Two field experiments were conducted to evaluate the effectiveness of repeated applications of several commercially availabl...

Establishing and Trafficking New Bentgrass Putting Greens Golf turf managers are pressured from the golfing community to reduce the establishment time of playing surfaces. To this end, accelerated grow-in procedures are implemented that eventually permit play on surfaces that are less than prepared to receive traffic. Research hassuggested that accelerated grow-in procedures and premature traff...

Rationale Ground ivy is a stoloniferous, perennial weed that can persist in turf. Growing at soil level, stolons infiltrate surrounding vegetation and establish new populations, which result in non-uniform turf. Approximately 62,000 lbs of 2,4-D were applied to Indiana homelawns in 1992.. A 2001 survey of Indiana lawn care operators (LCO) found 79% of respondents used 2,4-D either alone or in c...

BACKGROUND In an attempt to decrease injuries, newer forms of artificial turf have been marketed. The purpose of this study was to determine whether a new shredded rubber-based turf improves impact attenuation. METHODS An instrumented computerized impact recording device (IRD, Techmark, Lansing, MI) was dropped 20 times from a height of 48 inches onto five types of turf used by a professional...

abstract germination and emergence of cold tolerant lentil genotypes sometimes experiences low temperatures and variable rainfalls in the fall planting. this study was conducted to evaluate the effects of drought stress on germination stage of lentil genotypes. experiment was carried out with 18 lentil genotypes under five levels of water potential (0 , -0.4 , -0.8 , -1.2 , -1.6 mpa) using peg ...

We investigated the biology of Tiphia pygidialis Allen, a previously unstudied native parasitoid of masked chafer, Cyclocephala spp. grubs, in central Kentucky and the seasonal dynamics of Tiphia vernalis Rohwer, an introduced parasitoid of Japanese beetle, Popillia japonica Newman. T. pygidialis was active from mid-August to early October, parasitizing third-instar masked chafers, whereas T. v...

Kentucky bluegrass can produce quality fairways in the Midwest if it is not mowed too short. Keep track of research. Climates vary widely across the Midwest, complicating the choice of fairway turf grass species. New epidemics of gray leaf spot have weakened the popularity of perennial ryegrass, long a preferred fairway species in many parts of the Midwest. Cultivars are available that accentua...
