Technologies Developed

Department of Agricultural Entomology

  • ICAR-JRF coaching classes are being conducted for the benefit of students. Sizable portion of ICAR-JRF were bagged by this department.
  • More than 350 students in M.Sc. (Ag.) and 230 in Ph.D. have completed their degree programmes since inception. Students of this department, meritoriously pass in ICAR- ARS and NET examinations, excelled in obtaining awards of DST, CSIR – SRF and Jawaharlal Nehru award. PG and Ph.D. students are being made to specialize in areas of biological control, pesticide toxicology, chemical ecology, host plant resistance, storage entomology, apiculture, acarology and insect biosystematics.
  • This department has been identified as Centre of Advanced Studies in Entomology by ICAR during 1996 and redesignated as Centre of Advanced Faculty Training (CAFT). So far 40 Trainings have been conducted and 675 scientists have been trained from all over India
  • ICAR-Network AINP on Insect Biosystematics, ICAR-Acarology AINP on Agricultural Acarology, ICAR-CPW (Bio Control) AICRP on Biological control on crop pest and weeds and GOI scheme on Monitoring of Pesticide Residues at National Level are in operation at the department.
  • Developed management technologies for sugarcane woolly aphid, papaya mealybug, rugose spiraling whitefly and fall armyworm
  • Management of insecticide-resistance, insect resurgence and monitoring of pesticide residues in soil, plant, water, animal feed concentrate, egg, milk, oil and food and its mitigations strategies are being researched.
  • Research on pheromone, Agricultural Acarology is being carried out at Tamil Nadu Agricultural University since 1970s and pesticide residues in 1973.
  • Design and development of mechanical devices and gadgets for the management of storage pests earned patents for this department
  • Management of Indian honeybees, stingless bees and their usefulness as pollinators for increasing the agricultural production is being carried out.

Department of Plant Pathology

  • Mass production technologies for Trichoderma viride, Pseudomonas fluorescens and Bacillus subtilis have been developed for ecofriendly management of crop diseases. The mass production technology that includes data on bioefficacy and toxicology has been developed for the purpose of registration under Central Insecticide Board (CIB).
  • Molecular and immunodiagnostic methods have been developed for rapid and accurate detection of cassava mosaic virus, banana viruses, coconut root wilt, sugarcane red rot and mango anthracnose disease and aflatoxin contamination in grains of cereals.
  • Several resistant genotypes against important plant pathogens have been identified which are being used in the resistance breeding programmes as resistant donors.
  • Several new generation fungicides have been evaluated and integrated disease management technologies developed for the newly emerging diseases of various crops.
  • Genetically engineered crop plants with resistance to important pathogens have been developed and are being evaluated for gene expression and stability.
  • Several defense genes have been cloned and characterized from plants and microbes and deposited in the GenBank database.
  • Several varieties of edible mushrooms viz., Co1, Co2, Co3, M2 in oyster mushroom have been released for commercial cultivation.
  • Developed outdoor cultivation technology of paddy straw mushroom as intercrop in maize, banana and sugarcane fields for the first time in our country.

Department of Nematology

  • Nematologists of this Department working in Nem-main and AICRP (Nematodes) have been engaged in developing nematode management technologies and these recommendations are regularly included in the Package of Practices of the University.
  • Three emerging pests of Tamil Nadu have been recognized such as root knot nematode, Meloidogyne enterolobii from guava, first record from India; incognita from pomegranate, M.incognita and M.arenaria from mango, and M.indica from citrus, new records from Tamil Nadu.
  • Two of the fungal antagonists that infect nematodes especially those laying eggs in masses such as root knot nematodes, reniform, citrus and cyst nematodes are Purpureocillium lilacinum and Pochonia chlamydosporia. A venture capital scheme provided by the university was taken up under which the two bioagents are mass produced in talc formulations and distributed to farmers at a price of Rs. 120/- per kg. The produce is widely used for managing root knot nematode in vegetables, tube rose, cucumber grown in polyhouses, guava, pomegranate and banana. Almost 4.5 tonnes have been sold over a three years period across Tamil Nadu and other states.
  • Extension programmes conducted in the form of FIELD DAYS, FARMER’S MELAS, KISAN GOSHTI, NEMATODE AWARENESS CAMAPAIGNS etc.
  • HR activities have been strengthened by conducting three Refresher courses in Nematology for the new incumbents of AICRP nematodes from various centers across the Country during 2015, 2016 and 2017 (each 12 to 15 participants) funded by the Project Coordinator, AICRP (Nematodes).
  • A ten day training on Nematology for a Canadian student, Ms.Hannah Arseneault, I M.Sc student of Faculty of Agriculture, Dalhousie Agricultural Campus, Truro, Nova Scotia, Canada- from 11th to 22nd 2019 at Dept. of Nematology, TNAU, Cbe.
