Indian Society of Weed Science (ISWS) was established in 1968 coinciding with the green revolution in the country. Dr. R.S. Choudhry of Varansi (Uttar Pradesh) was the first president and Dr. M.K. Moolani of Hisar (Haryana) was the first Secretary of the society. The Society started publishing its journal ‘Indian Journal of Weed Science’ from 1969. Initially the Head Quarter of the Society was in Hisar which moved to Bangalore for nearly a decade (1980-1992). The HQ of the society was again shifted to Hisar and remained there till 2005. National Research Centre for Weed Science (now named as Directoratre of Weed Science Research) was established in 1989 at Jabalpur. Subsequently, with the strengthening of NRCWS (DWSR), the HQ of the society was finally shifted at Jabalpur in 2006. The society has been registered under the Karnataka Societies Registration Act, 1960 with registration No. SOR/BLU/DR/518/08-09. The official emblem of the society was designed by Dr. Bibhas Ray in 1977, the then Chief Agronomist of Farm Chemical Ltd, New Delhi.
