“Plant Pathogens and Principles of Plant Pathology” is an extensive, fundamental study guide on the biotic causes of plant diseases, morphological characteristics of fungi, bacteria, phytoplasmas, viruses, and viroids, the infection chain, host-pathogen interactions, defense mechanisms, and general plant disease management principles.
