Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Combined effect of entomopathogens with biorationals and chemical insecticides against some major insect pests of pulses
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Adarsha, K.; Purwar, J.P.
    The present investigation was conducted during rabi season of 2020-21 at Norman. E. Borlaug. Crop Research Centre, Integrated Pest Management Laboratory and Insect Pathology Laboratory, Department of Entomology, G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) with the objective to test compatibility of B. bassiana and B. thuringiensis with botanical insecticides, insect growth regulators (IGRs) and with chemical insecticides. Bioassay tests were performed to find combined effect of B. bassiana and B. thuringiensis with botanicals, IGRs and chemical insecticides against Spodoptera litura (Fab.). Field trial was conducted to evaluate the efficacy of B. bassiana with biorationals and chemical insecticides against sucking insect pests of Lentil. Compatibility study of B. bassiana with different biorationals and chemical insecticides indicated that U. dioica extract, A. pyrethrum extract, novaluron, spinosad, spinetoram and imidacloprid were found compatible with B. bassiana at all the lethal and sub-lethal concentrations, while diafenthiuron, profenofos, indoxacarb and flubendiamide were found incompatible with B. bassiana. In case of B. thuringiensis, U. dioica extract, novaluron, spinosad, spinetoram, indoxacarb and imidacloprid poisoned media exhibited minimum inhibition and found highly compatible to B. thuringiensis population growth at all its lethal and sublethal concentrations. while diafenthiuron and profenofos showed maximum inhibition to growth of B. thuringiensis at all of their lethal and sublethal doses. Bio assay tests were carried out to study the effect of these entomopathogens on the toxicity of botanicals, IGRs and chemical insecticides against 6 days old larvae of S. litura (Fab.). All the combination treatments showed higher dose-mortality response than the sole treatment of entomopathogen or the insecticide except indoxacarb. The combination of insecticides with B. bassiana showed 1.006–5.09 fold increase in toxicity of insecticides over sole treatment, while the increase was 1.15–5.74 fold in case of B. thuringiensis. Spinetoram 11.70 SC, novaluron 10.00 EC and flubendiamide 39.35 SC can be used in combination with these entomopathogens for the management of S. litura. Combinations of B. bassiana with biorationals and chemical insecticides were evaluated against major sucking insect pests (Aphis Craccivora & Acyrthosiphon Pisum) of lentil in field conditions. Treatments B. bassiana + profenofos, B. bassiana + imidacloprid, B. bassiana + diafenthiuron and B. bassiana + thiamethoxam were found more effective against the aphids among all the treatments. The present study indicated that flubendiamide, profenofos and diafenthiuron were found incompatible with either B. bassiana and B. thuringiensis under laboratory conditions. However, flubendiamide and profenofos with B. bassiana and B. thuringiensis showed synergistic effect against S. litura. Under field condition profenofos and diafenthiuron showed better results against aphids infesting lentil.
