Technical Abstract: A goal of the USDA, Agricultural Research Service, Application Technology Research Unit is to obtain more precise knowledge of fungicide coverage and plant canopy penetration using electron beam analysis(EBA). It is a combination of scanning electron microscopy, energy dispersive x-ray analysis and digital image analysis. Direct, precise assessment of residue using EBA will aid in modifications of application techniques and systems. Improved delivery of active ingredients onto target surfaces will lead to enhanced efficacy with reduced fungicide use and better disease control. Laboratory research and field studies, including experiments at production nurseries and orchards, involve assessment of canopy penetration, fungicide spray distribution, spray drift and associated water relations of target crops. Biopesticide coverage, nontraditional control methods and interactions between pathogens and plant surface structure are being studied to help achieve new and innovative disease management techniques.
