ARS plant pathologist Rick Bennett examines fungi in petri dishes.

A plant pathologist studies diseases of plants and looks for ways to prevent them or wipe them out when they show up. Plant pathologists also see how diseases mess up a plant's growth and development or cause damage to crops after they're harvested, or when they're transported to market or stored.
