Non Technical Summary
Pesticides are used and will continue to be widely used in agriculture with the current and growing population. Understanding pesticide fate and behavior is of utmost importance in all parts of the world to ensure the environment and/or human health aren't adversely affected. Following an application, pesticides have many different fates. Pesticides may move off-target through the air, erosion, soil, or water or they may be sorbed by plants or animals, among other things. Understanding how pesticides behave in the environment ensures that scientists may accurately predict if pesticides may pose adverse effects to the environment and/or human health. Research will be completed to answer specific questions related to pesticide fate and behavior in agricultural systems with the goal of devising comprehensive integrated pest management principles.

Goals / Objectives
The major goals of this project include: 1 - characterize pesticide fate and behavior in the environment 2 - sharacterize trace element fate and behavior in various systems 3 - identify pesticide tranport, transfer, and transformation mechanisms including reaction of chemicals with soil colloids 4 - assess pesticide mobility in soil, air, and water in various crops 5 - assess off-target pesiticide injury.
Project Methods
Research will be initiated to characterize the fate and behavior of pesticides in various agronomic systems. Field, greenhouse, and laboratory experiments will be completed to characterize pesticide fate and behavior. Specifically, leaching, runoff, sorption, and degradation will be quanitified. Further, factors that affect off-target injury will be determined from similar experiments. Fate and behavior of select trace elements will also be evaluated. Sorption, cycling, and uptake will be evauated from field, greenhouse, and laboratory experiments. Data from the experiments will be analyzed and compiled into publications to disseminate the research findings to the target audience. Publication format will include classroom instruction, extension and outreach training, and presentations at professional society meetings.

Outputs
Target Audience:Land managers, agricultural producers, specialty crop producers. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Dr. Gannon teachestwo graduate courses each Fall semester, CS725 (pesticide chemistry) and CS727 (pesticide behavior and fate). Further, Dr. Gannon has continuedto advise graduate students by chairing or co-chairing five PhD students and fiveMS students. Further, he serves on the committees of ten other graduate students How have the results been disseminated to communities of interest? Dr. Gannon initiated research to characterize pesticide exposure in various systems. Data generated will assist management personnel and land managers to ensure adequate protocols are followed to minimize or eliminate pesticide exposure. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Dr. Gannon conducted research trials to characterize fate, behavior, and cycling of trace elements. This has implications across various systems including turfgrass where EPA initially ordered a phaseout of organic arsenical pesticides that is currently being reviewed. Additionally, this research has wide-spanning implications from a human exposure perspective. Dr. Gannon is also involved in contemporary research assessing impacts of the Dan River coal ash release on agricultural soils and crops as well as research to discern factors which affect herbicide resistance.
