Plant Pathology deals with the identification and treatment of plant diseases. Diseases in plants are caused by many agents, micro-organisms being the most common. Fungal, bacterial and viral diseases cause some notorious diseases to crop plants. Plant pathology holds great importance due to its influence on food security. Keeping in view its significance, a book on Plant pathology has been reviewed here. The book is named Plant Pathology by G.N Agrios 5th edition.

Next few chapters focus on the pathogens. Topics like the effects they have on plants and the mechanism of their attack are covered. Plants have certain defense mechanisms which enable them to resist against the infection caused by pathogen. These defenses may be structural, biochemical and of other nature.
