Resumo:

Increasing irrigation efficiency on turfgrass could help reduce water consumption on large turf facilities. Two experiments were conducted using perennial ryegrass (Lolium perenne (L.) Derby) to evaluate the potential of using remote sensing to estimate turf water status, predict daily evapotranspiration (ET), and estimate turf biomass. In the first experiment a crop water stress index, utilizing remotely sensed canopy temperature, were used to schedule irrigations on 6 of 10 drainage lysimeters. Three of the remaining lysimeters were irrigated used on meteorological estimates of ET calculated

Overseeding trials were conducted to evaluate the turf-type fitness of cool season grasses for use in the desert when bermudagrass is dormant. Perennial ryegrass, fine fescues, rough stalk bluegrasses and creeping bentgrasses were tested for turfgrass quality, color, percent ground cover and uniformity under a close mowing (3/8 inch) regime. Entries varied significantly from each other once seasonal hard frosts did not recur after January. Certain entries had better turf performance under hot (late spring) conditions. Both commercially available and experimental germplasm were evaluated.

The impact associated with these events is due to the placement of physical structures such as stages and seating areas and pedestrian and vehicular traffic on the turf surface.

The majority of outdoor sports are played on natural turf pitches. Throughout the playing season, a pitch has continual player interaction, which, during periods of sustained unfavourable conditions, can cause the turf to tear up (shear) under player contact. This is most evident in Rugby Union scrummages, which create deep divots in the turf and rootzone that reduce player safety and are criticised by the media. However, little is known of the turf/rootzone strength to depth, termed 'shear stability' in this thesis, and there is currently no appropriate means to test this property. In order t

Applications of sulfentrazone were applied to 2.75" mowed tall fescue under hot-humid desert conditions to assess post application response. A uniform decrease in color occurred shortly after application at the 0.375 lb. AI/A rate. The effect was short lived and tended to be minimal in split application treatments. Leaf cupping/twisting was exacerbated from applications of sulfentrazone, especially at the 0.375 lb. AI/A rate. At 0.125 and 0.250 lb. AI/ rates, the leaf cupping was much less noticeable. Percent plot showing the leaf cupping symptoms was also rate dependent and generally ranked w

Sulfentrazone was applied in single applications at the rates of 0.125, 0.250 and 0.375 lbs. AI/A, and after 30 days in split rate combinations of 0.125/0.125, 0.250/0.250 and 0.125/0.375 lbs. AI/A. Turfgrass color scores were slightly diminished form sulfentrazone characterized by a lighter uniform color change on mowed common bermudagrass. The response was generally rate dependent. Imazaquin caused a light green turf to develop while halsulfuron had no effect. After the first application was made, sulfentrazone treated turfs exhibited leaf twisting/cupping effects at 3 and 7 days after treat

Herbicides applied for post-emergence control of wild parsley differed in turf injury and weed control. All products tested required multiple applications (21 days apart) to attain acceptable weed control levels. Weedone (2, 4-D) has the quickest, highest, and longest lasting amount of weed control. Weedone (2, 4-D) caused minimal injury to the common bermudagrass turf. Bromoxynil at the low rate of 2.0 lbs. ai/a caused minimal injury to the turf, but provided low levels of weed control. Bromoxynil at the high rate of 3.0 lbs. ai/a caused considerable injury to the turf and moderate to high we
