Plant Pathology is the scientific study of plant diseases caused by pathogens and environmental conditions. They are applied to the population of plants before infection takes place. Apart from undertaking a considerable amount of work on the identification of diseases, Kirk did much to educate farmers and fruitgrowers to appreciate what diseases were and how they could best be controlled. Plant pathologists embraced integrated disease management by applying fundamental information on loss potential and pathogen biology, ecology and epidemiology, and applying the basic concepts of plant disease management.
