| Abstract/Contents: | "There has been a lot of concern in recent months about the use of pesticides in the United States. The greatest use of fungicides in the USA is on turfgrass. Systems have been developed that monitor the weather and that forecast disease infection periods for Phythium blight and brown patch of turfgrass. A 25% reduction in the amount of fungicide applied to 'Manhattan' ryegrass for Pythium blight control was obtained during 1988 using disease-forecasting procedures. A 75% reduction in the amount of fungicide applied for brown patch control was achieved in 1989. These results were achieved by using disease-forecasting information, rather than using standard spray schedules. The objectives of this research project are to determine: (1) if selected fungicides can be found in effluent from putting greens under our test conditions, and (2) if fungicides are found in the effluent, establish if the reduction in fungicide applications realized by disease prediction/postinfection spraying results in an equal or greater reduction in fungicide in the effluent. A 25 x 50-ft USGA-specification putting green containing 32 replicated plots was built to determine if fungicides can be found in the effluent from putting greens. Each plot is 5 x 5 ft with a 1-ft border and contains a 3-ft diameter by 1.5-ft deep lysimeter. Each lysimeter is attached to a 2-in drain line which ends in a central collection facility. The green was finished in June 1990 and was seeded with 'Penncross' creeping bentgrass. Effluent from each lysimeter will be collected daily and analyzed on a Kratos MS25 double-focusing mass spectrometer interfaced with a Carlo Erba 4100 series gas chromatograph." |
