The main tasks of the department are to diagnose bacterial diseases that cause damage to plants and plant products by using morphological, biochemical, serological, molecular and biological methods, to determine their prevalence and damage levels, to reveal their biology, epidemiology and control methods.

TAGEM and other outsourced projects are carried out in the Department.

These are:

• Screening studies of the bean bacterial wilt disease "Curtobacterium flaccumfaciens pv. flaccumfaciens" to carry out throughout the country,
• Investigation of the use of bacteriophages in the control of Pseudomonas syringae pv syringae which is the causative agent of bacterial branch cancer in stone fruits,
• Inventory and validation of quality control procedures for the extraction of nucleic acids for real-time PCR used for pest identification
• To carry out resistance studies against bacterial diseases on a national and regional basis in dry bean breeding studies and to develop resistant varieties.
• To determine the rot pathogens encountered in onion production areas and warehouses and to carry out studies to prevent and manage them,
• Determination of the presence of Xylella leaf blight disease in the Central Anatolian Region and detection of vector insects
• Cataloging the disease-causing pathogens in cultivated plants and creating reference cultures by long-term preservation methods.
