Biocontrol lab

The quest to continually improve on solutions for comprehensive disease management in the bio-control field led to the establishment of Trichoderma and Pseudomonas Laboratories in this Department. TNAU is the first in India develop Talc based biocontrol agents commercially in early 90’s. The underlying objective was to perfect lab-to-land technology; i.e., developing delivery mechanisms for various bio-control agents so that they are made available to end-users in different parts of the country at reasonable rates. The lab paved the path for eco-friendly and integrated pest management techniques for various crop plants. The major activities of biocontrol lab are isolation, evaluation and release of biocontrol agents as well as research to genetically improve beneficial organisms. Major Biocontrol agent deal by as are Trichoderma viride (T. asperellum), Pseudomonas fluorescens, Bacillus subtilis, Chaetomium globosum, Ampelomyces quisqualis, Beauveria bassiana etc.

Virology lab

The  systematic  plant  virus  studies  were  initiated  at  the  department  of  Plant Pathology, TNAU, Coimbatore under the able guidance of    Prof. K. Ramakrishnan. He  and  his  dedicated  team  of  research  workers  contributed  for the  identification of etiological agents of cassava mosaic disease, big bud disease of tomato, management   of   citrus   tristeza   disease   through   cross   protection   and   aerated steam therapy of sugarcane diseases. This pursuit flourished further under the leadership of  Prof.  P. Narayanaswamy, Prof.  Sabitha Doraisamy, Prof.  M. Ramaiah and Prof. R. Rabindran. At present the Plant Virology research work is being continued with half a dozen of budding scientists.

Molecular diagnostics based on labeled nucleic acid probes, ds RNA anlysis, Polymerase chain reaction (PCR), Reverse transcription polymerase chain  reaction  (RT-PCR),  Immunocapture  Polymerase  chain  reaction  (IC-PCR) and multiplex Polymerase chain reaction (M-PCR) techniques have been developed and used for the detection and identification of several RNA  and DNA viruses infecting different crops.

The IPM packages have been developed for the management of virus diseases in different agro-eco systems of Tamil Nadu. Currently our research focus is on the characterization of different plant viruses and relationships with their insect vectors; exploiting RNA silencing approach for the management of viruses viz., GBNV, TSV and CMV.

This Laboratory is equipped with autoclaves,  Laminar flow chamber, PCR machine, Deep freezer (-80ºC),Vacuum flash evaporator, Electrophoresis units,  Gel documentation unit, Cooling centrifuge, temperature controlled incubator shaker and microwave oven.

Culture collection

The Culture Collection was established in the Department of Plant Pathology, TNAU, Coimbatore with a view to collection and documentation of Plant Pathogenic and Beneficial Microorganism in this region. Most of these cultuers have been maintained, mainly as working collection, by individual researchers for short to long term period of time. Our aim of establishment is to provide cultures for research projects, education and for sustainable use in the future. So for we are maintaining 120 numbers of cultures obtained from various sources.
