||Plant pathologists study and try to develop cures for plant diseases. Yes, plants catch diseases just like people, and some of these diseases can destroy entire crops. Chestnut blight is an example of a plant disease that devastated a forest tree.
Plant pathologists get to use all the modern tools of science: light and electron microscopes, DNA analyzing machines and computers.
Plant pathologists usually get hired by universities, government agricultural agencies, and private industry. Some of them do "applied research," like developing better pesticides for controlling diseases and breeding disease-resistant plants.
