The pathogenic tendency of Sporisorium reilianum as illustrated above is to carry out its life cycle in congruence with the growth of either maize or sorghum as the host plant. For example, In place of ears of corn; plant-like sorus develop. The onset of this smut is sporadic and slowly progressive however disease severity is high.
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1]
The disease starts out as yellowing and drooping on one side of the plant. Leaf wilting, plant stunting, browning of the vascular system, leaf death and lack of fruit production also occur. [8] F. oxysporum f. sp. melonis attacks muskmelon and cantaloupe. It causes damping-off in seedlings and causes chlorosis, stunting and wilting in old plants.
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors).

Because of this interaction, the terminology used in phytopathology often comes from other disciplines including those dealing with the host species (botany / plant science, plant physiology), the pathogen (bacteriology, mycology, nematology, virology), the environment and disease management practices (agronomy, soil science, meteorology ...
