Golfer Exposure To Pesticides, Jeffery Doherty
Golfer Exposure To Pesticides, Jeffery Doherty
Doctoral Dissertations
There is concern among industry regulators, turfgrass managers, and the general public over human exposure to pesticides following their application to turfgrass. The residential aspect of turfgrass applications raises concerns about exposure to infants and children, as well as adults. To accurately determine the exposure of golfers to turfgrass pesticides, it is necessary to understand their transfer and absorption dynamics, as well as the routes of golfer exposure. Previous research has demonstrated that exposure to some turfgrass pesticides is at a level that would concern USEPA risk assessors using the USEPA Hazard Quotient (HQ) criteria (1). This current research used …
The Effect Of Management Practices On Bacterial, Fungal, And Nematode Communities On Cool Season Turfgrass, Elisha Allan-Perkins
The Effect Of Management Practices On Bacterial, Fungal, And Nematode Communities On Cool Season Turfgrass, Elisha Allan-Perkins

Golf courses comprise 50 million acres in the United States of highly managed turf susceptible to abiotic and biotic stressors. A growing area of interest is utilizing microbes to improve plant growth, increase disease and stress tolerance, and reduce pathogens. In order to develop these new practices, we must gain an understanding of turfgrass microbial communities and how they are affected by management practices. We characterized bacteria, fungi, and nematodes on three golf courses: one organic, one with reduced inputs, and one conventional. We took samples from three management areas on each course representing different management intensities (roughs, fairways, and …
