Areas
of Special Interest:
- Biotic and abiotic diseases of
nursery, greenhouse and landscape plants.
- Electron beam analysis of
pesticide spray drift and canopy penetration
Research
Interests:
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.
