The Department of Pest Management (DPM) formerly the Department of Crop Protection (DCP), and later the Department of Plant Protection (DPP) is one of the pioneering departments of the college of agriculture. It began in 1974 through the pioneering efforts of Dr. Fernando A. Bernardo when the Visayas State College of Agriculture (ViSCA) was established, and Dr. Emiliana N. Bernardo who became the first department chairman. The creation of DPM was embodied in Board dpm-edResolution No. 24 Series of 2001 dated November 14, 2001.

Its primary instructional responsibility is to train students (both undergraduate and graduate) in the area of plant Protection, Plant Pathology, Entomology and Weed Science. In addition to instruction, the staff of the department also conducts activities in research, extension and production in consonance with the program of the Visayas State University. DPM is housed in a two storey building from equipped with lecture and laboratory rooms, faculty cubicles, greenhouses and equipment.

The department consists of four sections equivalent to the four fields of specialization, namely: Entomology, Plant Pathology, Weed Science and Vertebrate Pests. Undergraduate students who wished to major in plant protection therefore have four options to the fields of specialization they are going to pursue.

DPM now offers undergraduate and graduate courses in Plant Protection, Plant Pathology, Entomology Weed Science and undergraduate courses leading to specialization in Vertebrate Pests.

The regular faculty force in the department is composed of 8 with Ph.D.'s, 1 Ph.D. candidate and five with M.S. degrees. Five affiliates from other departments/research centers with Ph.D., 1 with M.S. and 1 with B.S further strengthen this.
