Reported potato cyst nematode for the first time- from Nilgiri, India. 64. Anton de Bary (Germany) [Father of Plant pathology/Founder of Modern Mycology] (1831BC): Described the account of development and sex in number of Phycomycetes and Ascomycetes. Reported the seed transmission of tobacco ring spot virus by infection of Megagametophytes. Recommended mercuric chloride as wood preservative. Gave the final proof that bacteria could be the incitants of plant diseases. The first disease forecasting system in plant pathology was developed for grape vine downy mildew (Plasmopara viticola) in 1913 (Muller’s incubation calendar, Germany). Wrote “Microorganism in Diseased Plants”. karl_obispo. Studied the life history of cereal smuts. ancient era, medieval era, pre-modern era, modern era?and present era which are useful to understand the development made on the subject of plant pathology and further scope of … Elias Magnus Fries (Sweden) [Linnaeus of Mycology/Father of systematic Mycology] (1821 BC): Regarded the rust and smut fungi as products of diseased plants. •“Greatest figure in history of pathology” •Used the microscope for tissue analysis from autopsies •Initiated the idea that changes in diseased states can be traced to alterations in cells •The father of cellular pathology •Pathology emerged as a separate academic discipline in 2nd half of the C19 Balachandera Bhawanishankar B Mundukar (1948 BC): Established Indian Phytopathological Society with its journal ‘Indian Phytopathology’. This name was proposed in honor of Robert W. Goss, a former chair of the Department of Plant Pathology and the first full-time Dean of the Graduate College for the University of Nebraska, who pioneered the early development of modern plant pathology in … 16.
