• Electron beam analysis of pesticide spray drift and canopy penetration

Dr. Krause is a USDA/ARS plant pathologist whose mission is to improve plant health, to develop safer, more effective chemical and biological strategies to control plant disease while preserving the environment. He uses electron beam analysis to directly identify and quantitate fungicide particles and droplets on targeted plant surfaces. He leads a plant bioscience project that seeks to improve pesticide application technology to optimize chemical and biological control of nursery, orchard, and greenhouse pathogens. Part of the future thrusts of his program include visualizing host/parasite/fungicide interaction on the phylloplane characterization of chemical pesticide injury, as well as identification of abiotic plant stress injury caused by air pollutants or other stress factors. A scanning electron microscope energy dispersive x-ray analyzer interfaced with digital light microscopy in his laboratories are specifically used to accomplish his mission. He works closely with other USDA-ARS scientists and OSU agricultural engineers and is associated with the Laboratory for Pesticide Control Application Technology at the OARDC, a consortium of scientists from several agriculture-related disciplines interested in plant health.
