Oz-based scientist delivers lecture on weed biology

The Ludhiana Chapter of Indian Society of Agronomy (ISA) organised a talk by Professor Bhagirath Singh Chauhan from The University of Queensland, Australia. In appreciation of his outstanding contributions to weed science, Professor Chauhan was invited to deliver a talk on “Weed biology: An important science to develop effective weed management strategies” in the Department of Agronomy. He has a wide experience in weed biology, weed seed ecology, non-chemical weed management options, herbicide use, management of herbicide-resistant weeds, and integrated weed management systems using agronomic and crop improvement components.

Professor Chauhan provided an in-depth exploration of the biological aspects of weeds and how this knowledge was essential for developing effective weed management approaches. He emphasised on the importance of studying the reproductive mechanisms, growth patterns, and ecological interactions of weeds to create targeted strategies for controlling their spread. He also discussed how weeds adapted to different environments and their ability to evolve resistance to herbicides, stressing the need for integrated weed management. Through his expert insights, Prof Chauhan highlighted the importance of weed biology for addressing the challenges faced by modern agriculture and ensuring sustainable weed management. The talk was succeeded by an interactive session in which Prof Chauhan responded to the queries about practical challenges in weed management.
