Adjunct Associate Professor

Lab web site: Krause Lab

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.  Some of his work involves electron beam analysis to identify and quantitate fungicide particles and droplets on targeted plant surfaces. He leads a plant bioscience project to improve pesticide application technology by optimizing chemical and biological control of nursery, orchard, and greenhouse pathogens.  Future program areas omc;dievisualizing 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 among methods used.   Krause 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.
