Technical Abstract: Thorough knowledge of the delivery, dispersal, and fate of fungicides is crucial to insure effective disease management. Accurate fungicide distribution with minimal off-target contamination, enhanced retention of active ingredients onto targeted surfaces, and reduction of drift will lead to more effective crop management. Practical research and development of more precise application systems, improved fungicide formulations, precise detection and mediation of water status to accomodate optimum fungicide retention, and novel, direct assessment methods like electron beam analysis (EBA), will lead to enhanced fungicide efficacy and minimized pesticide use. EBA is a combination of scanning electron microscope, energy dispersive x-ray analysis, digital beam control and image analysis. Advancments improving fungicide efficacy and reducing pesticide applications safeguard environmental quality and enhance producer profitability.
