Our history

Agri-Analysis was founded in 1981 by plant pathologist Glenn Friebertshauser, who desired to establish his own laboratory to diagnose plant diseases after completing his studies in University of California, Davis. His interest spanned fungal, viral and bacterial pathogens of plants, vines, trees and soil. His initial service to the agricultural community was in the development of a commercially applicable assay for lettuce mosaic virus (LMV), allowing for screening of virus-free lettuce seed lots before planting. In the mid-80's he became interested in diseases of grapevines and saw the need in the industry for laboratory assays to diagnose the presence of viral pathogens such as fanleaf virus, leafroll associated viruses and corky bark virus. Later, he developed additional assays for the bacterium Xylella fastidiosa (causal agent for Pierce's Disease in grape vines and almond leaf scorch) and fungal diseases, notably those associated with Esca or Petri Disease, also known as young vine decline.
