The plant disease pyramid : the relevance of the original vision of plant pathology in 2020

Abstract

In 1926, Professor Paul A. van der Bijl made an address to the South African Association for the Advancement of Science in his capacity as President of Section C of the Association, entitled ‘Landmarks in the development of the science of plant pathology and of disease control’.1 The talk itself marks a key moment in the development of plant pathology as a discipline in South Africa, as Van der Bijl had been appointed 5 years earlier as the first Professor of Plant Pathology and Mycology in South Africa, at Stellenbosch University. The field was just being established, not only in South Africa, but in many parts of the world, and its distinction from other disciplines was a matter of pride.
