Abstract
The majority of plant health problems categorized as plant diseases are caused by microorganisms. As the name implies, these are extremely tiny disease-causing agents that ordinarily require a microscope to be seen. The very minute size of these disease-causing pathogens accounts for the mystery that often surrounds their presence and impact in the garden. The pathogenic microorganisms that attack garden vegetables, including tomato, can be classified into three major groups: fungi, bacteria, and viruses.
