Pesticide Fate in the Environment

Overview

OLYMPUS DIGITAL CAMERAPesticides such as fungicides, herbicides, and insecticides are commonly used to maintain high quality turfgrass on golf courses, lawns, athletic fields, and sod fields.  The potential non-target effects of pesticide usage on turfgrass are well documented.  However, in addition to the environmental and toxicological implications of pesticide usage there is a significant financial impact of pesticide usage on turfgrass managers that may adversely affect their operation.  For both financial and environmental reasons, it is then imperative to have a more complete understanding of the impact of various environmental conditions on the activity and persistence of turfgrass pesticides.  This information can then be used to more precisely predict when pesticide applications and reapplications are required, which may reduce some of the financial and environmental non-target impacts of turfgrass maintenance.
