Quiz on Plant Pathology | Plant Science Quiz

Plant pathology, otherwise called phytopathology, can be defined as a branch in botany or agriculture that deals with causal organisms, etiology, symptoms and control of diseases. The foundation of modern plant pathology was laid by Parsoon (1801) and Fries (1821). They believed that microorganisms originate from diseases. A French scientists Prevost (1807) found that diseases are caused by microorganisms. The most important discovery regarding the plant and pathogen relationship was established by Anton de Bary (1831-1888). He made experimental findings of the causal organism of the late blight of potato. The disease caused by rust and smut are also illustrated on the basis of their causative organisms and their evolution with the host plant.Read more about rust and smut>>
