The herbicide resistance problem in weeds is continuously increasing in India. To address this important issue a webinar was organized on 29-1-2021 by the ICAR-Directorate of Weed Research Jabalpur in collaboration with Indian Society of Weed Science. It was chaired by the Dr. J.S. Mishra, Director, ICAR-DWR, Jabalpur and convened by Dr. Sushilkumar, Principal Scientist and President, Indian Society of Weed Science. Dr. Samunder Singh, President, International Weed Science Society and Retd. Prof and Head Agronomy CCS HAU, Hisar has given the Lead lecture on ‘Herbicide resistance in India: problems and management. He presented current status of herbicide resistance in weeds in India and global level and way to manage them. Globally there are 515 herbicide resistance cases. He also presented rapid detection kit for quick identification of herbicide resistance in weeds. After the lecture, very interactive discussion was held on herbicide resistance in weeds specially Phalaris minor, Chenopodium album, Rumex dentatus, etc. It was felt that repeated application of same herbicides / or herbicides with same mode of action are the major reasons behind development of herbicide resistance in weeds. In such cases, crop/herbicide rotation along with use of herbicide mixture of different mode of action may delay in development of herbicide resistance in the weeds.

Dr. Jonathan Gressel Professor Emeritus Department of Plant Sciences, Weizmann Institute of Science, Israel, Dr. A.K. Gogoi, Ex ADG (Agronomy), NRM, ICAR, Delhi, Dr. N.T. Yaduraju, Ex Director, DWR, Jabalpur,, Dr. J.C. Majumdar from Crop Care Federation of India, and many senior weed scientists also participated in this webinar. Approximately 260 number of weed scientists, faculties of AICRP-Weed Management centres, industry personnel, students, SRFs, ISWS Members, etc. participated in the webinar. Dr. Shobha Sondhia, Principal Scientist, ICAR-DWR, Jabalpur and Secretary of Indian Society of Weed Science conducted this Webinar and proposed vote of thanks.
