Shanmugapriya, D. 

Here shanmuga Priya, pursuing Ph.D. in Plant Pathology. I would like to share few words about the Department of Plant Pathology. TNAU is the leading agricultural university in India with wide variety of branches and well-specialized faculty. TNAU faculty and students majorly contribute for the welfare of the farming community and scholars are finding solution to many unsolved problems to the research thirst. Here about our department Plant Pathology, which is well equipped with high tech instruments, required for advanced research from detection to diagnosis in the field of disease management. My current research work is on development of microbial consortia for managing major soil borne diseases in glory lily funded by National Medicinal Plant Board (NMPB) – GOI, New Delhi. I can able to work at an advanced level in my research due to constant support and ideas received from my well experienced faculties, which will help me for my future career. I can proudly say that I am a product of TNAU!

Sivagnanapazham, K. 

Myself K. SIVAGNANAPAZHAM pursuing III Ph.D (Plant Pathology) in Department of Plant Pathology, Centre for Plant Protection Studies, TNAU, Coimbatore. I have completed my Masters in Plant Pathology during 2018 – 2020. In my course work, I have attained wider knowledge in various aspects of Plant Pathology (Mycology, Virology, Bacteriology, Biological control, Disease resistance in plants, Seed health Technology, Diseases of crop plants, Plant Quarantine etc).I have also became expertise in diagnosis, documentation and characterization of Plant Pathogens. My research work was on “Management of Cabbage head rot (Sclerotinia sclerotiorum) using novel biocontrol agent (Coniothyriumminitans)”. I could able to publish my research work in peer reviewed well reputed journal “Egyptian Journal of Biological Pest Control”.I have qualified for ICAR SRF; cleared ASRB mains and ICAR NET in Plant Pathology due to constant support and encouragement of faculty. The well established laboratories with high tech instrument facilities which helped me to learn many advanced techniques / tools for Plant Pathology research. Based on sound knowledge with excellent mentors, my department is flourishing with several externally funded projects. Hence I got student Senior Research Fellowship from an externally funded project (DST – SERB) to pursue my Ph.D on “Pathogenomics of emerging whitefly transmitted begomoviruses of cucurbitaceous crops in Tamil Nadu: Characterization of ecologically diverse begomoviruses and population dynamics of whitefly biotypes in virus transmission”. It is a great opportunity for my future carrier.

My Ph.D period at the Department of Plant Pathology, TNAU Coimbatore was the ever memorable golden period of my learning and training in the research domain of the subject, as well as my personality development. We popularly refer it as Lab 20, the place where I spent 3+ years working day and night during my Ph.D with lots of love and involvement in the subject. It was an eye-opening experience in molecular plant pathology research. The motivation and guidance towards high impact research and publications, and international networking helped me later to achieve successful post-doctoral research career in five Universities in three foreign countries – France, Canada, and the USA. I have been hailed by my current students and colleagues for my confidence level as a good teacher and innovative researcher. I credit my success to my mother institute TNAU. Thank You TNAU!

Salah EddinKhabbaz, Ph. D.,


I am a Research Scientist for over 15 years with extensive experience in soil and plant disease, plant-microbe interactions, microbial ecology of plant growth promotion rhizobacteria (PGPR), and applied research projects in agricultural sciences. I was the luckiest students who joined a post-graduate program at Tamil Nadu Agricultural University, Coimbatore, India, between 2000-2006. I obtained my Master of Science (M.Sc. 2000-2002) and Doctor of Philosophy Degrees (Ph.D., 2003-2006) from the Department of Plant Pathology, Centre for Plant Protection Studies (CPPS), TNAU. Throughout my study years, I acquired valuable knowledge about plant pathology, plant diseases diagnosis and management, biocontrol, and biotechnology. The department was well-equipped and teaching and performing advanced searches are synergistic with each other to perform cutting-edge research. I am eternally grateful to all professors and staff at TNAU, and to all my fabulous classmates for all they did, which I will never forget.
