- 1. Phytopathology is the scientific study of plant diseases, their causes, mechanisms of infection, and methods for disease control. It involves the study of how plant pathogens interact with their hosts, leading to the development of symptoms and damage. Phytopathologists work to identify, characterize, and manage plant diseases through research, education, and practical solutions. By understanding the complex interactions between plants, pathogens, and the environment, phytopathologists play a vital role in protecting crops, forests, and natural ecosystems from disease outbreaks and ensuring global food security.
