Factsheet information for the plant health issues represented by the images on the 2020 TPDDL calendar were written by graduate students enrolled in the Department of Plant Pathology & Microbiology  DR. DAVID APPEL’s Graduate level Introductory Plant Pathology course (PLPA601) in the 2019 Fall semester.  This effort by Extension, Research & Teaching faculty members in the Department of Plant Pathology & Microbiology at Texas A&M University aims to provide a high impact learning opportunity to train graduate students by tasking them with producing an informational output directed to the general public.  This activity provides an opportunity for the students to write, learn and produce a  (hopefully) useful product to communicate information on plant health issues to the public.
