Phytopathology is the study of plant diseases, their causes, mechanisms, and management. Scientists and researchers in this field work to understand how pathogens such as bacteria, fungi, viruses, and nematodes infect plants and cause diseases, as well as how to prevent, control, and manage these diseases. Phytopathologists play a crucial role in ensuring the health and productivity of crops, forests, and natural ecosystems. They use a combination of laboratory experiments, field studies, and genetic analysis to study plant-pathogen interactions and develop strategies for disease management.
