✹Like animals, Plants also suffer from various diseases.
✹The Biological Agents that causing disease to plants are known as pathogens.

Common Plant Pathogens are:
               ◑ Virus
               ◑ Bacteria
               ◑ Fungi
               ◑ Nematodes

Plant disease, an impairment of the normal state of a plant that interrupts or modifies its vital functions. All species of plants, wild and cultivated alike, are subject to disease. Although each species is susceptible to characteristic diseases, these are, in each case, relatively few in number. The occurrence and prevalence of plant diseases vary from season to season, depending on the presence of the pathogen, environmental conditions, and the crops and varieties grown. Some plant varieties are particularly subject to outbreaks of diseases while others are more resistant to them. See also list of plant diseases.
