[2] [3] During his twenty years in India, he began large scale surveys on fungi and plant pathology and published the landmark book Fungi and Disease in Plants: An Introduction to the Diseases of Field and Plantation Crops, especially those of India and the East (1918) [4] and has been called the Father of Mycology and Plant Pathology in India.
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1]
It was established in 1952 and was originally published by the Ministry of Agriculture. The journal publishes research articles and critical reviews on all aspects of plant pathology except for articles on pesticide and resistance screening. [1] The editor-in-chief is Matt Dickinson.
Most bacteria associated with plants are saprotrophic and do no harm to the plant itself. However, a small number, around 100 known species, cause disease, especially in subtropical and tropical regions of the world. [15] [page needed] Most plant pathogenic bacteria are bacilli. Erwinia uses cell wall–degrading enzymes to cause soft rot.
The American Phytopathological Society (APS) is an international scientific organization devoted to the study of plant diseases (phytopathology). APS promotes the advancement of modern concepts in the science of plant pathology and in plant health management in agricultural, urban and forest settings.
The Annual Review of Phytopathology is a peer-reviewed academic journal that publishes review articles about phytopathology, the study of diseases that affect plants.It was first published in 1963 as the result of a collaboration between the American Phytopathological Society and the nonprofit publisher Annual Reviews.
Neergaard authored a two-volume text entitled Seed Pathology (1977), that focused on a wide variety of seed pathology issues, ranging from the economic significance of seed-borne diseases to the assessment of seed-borne inoculum. It has served as a reference and teaching standard for the science of seed pathology throughout the world.
A spectrum of hemibiotrophic plant pathogens, including the bacterium Pseudomonas syringae and the oomycete Phytophthora infestans (potato blight), also exhibit characteristics of both biotrophs and necrotrophs and thus are called hemibiotrophs, depending on the stages of their life cycle.
