George Ainsley is a plant pathologist at a university diagnostic clinic who also writes for Biology Insights. In the diagnostic facility, he evaluates infected roots, blighted leaves, and fungal cultures submitted by commercial growers and home gardeners trying to identify crop failures. His laboratory testing identifies bacterial rots, viral vectors, and foliar blights before outbreaks spread through fields or orchards. Ainsley has academic training in microbiology and plant pathology, applying microscopic examination and culture plating to track plant diseases across different seasons.
