University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    STUDIES ON THE ROOT-KNOT NEMATODE (Meloidogyne enterolobii) WILT COMPLEX IN GUAVA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-08) PUSHPALATHA, R.; Ravichandra, N. G.
    Root-knot nematode, Meloidogyne enterolobii was reported for the first time on guava in 2016 from Karnataka and is emerging as a major threat to commercial production of guava across India. Several fungi associated with M. enterolobii infested guava rhizosphere increased the wilting of guava plants. Investigations were carried out on isolation and identification of nematode and major pathogenic fungi associated with nematode infested guava rhizosphere, screening popular guava cultivars for their reaction to M. enterolobii and management using various treatments viz., Purpureocillium lilacinum, Pochonia chlamydosporia, Fluopyram, Fluensulfone, Bacillus velezensis, Pseudomonas fluorescens, Bacillus pumilus and Carbofuron 3G under field condition. Among the several fungi, Fusarium solani was predominant in the rhizosphere of guava infested with M. enterolobii. Among eight guava cultivars (Lalit, Allhabad Safeda, Sardar, Arka Mridula, Arka Poorna, Arka Rashmi, Arka Kiran and Arka Amulya), it was observed that Lalit and Allahabad Safeda were moderately resistant to M. enterolobii with root knot indices of 3.0 at 60 days after nematode inoculation. Under field condition, new nematicide Fluopyram 400 SC@500g a. i. ha-1 (0.23 mL L-1 plant-1) at monthly interval was effective in reducing the nematode population in soil (650/ 200 cc) , root (99.33 / 5 g) and maximum reduction of galls (13.33/ 5 g of root) and egg masses (14.00/ 5 g of root) over control ( 1033.33/ 200 cc, 260/ 5g of root, 27.33/ 5 g of root, 29.67/ 5 g of root respectively).
