Overview

Background

Professor Bhagirath Chauhan joined the Queensland Alliance for Agriculture and Food Innovation (QAAFI) at The University of Queensland in 2014. He now has a joint appointment with QAAFI and SAFS at UQ. He leads research on weed biology and weed management in different crops, including wheat, maize, sorghum, mungbean, soybean, chickpea, rice, and cotton. He has studied the seed ecology of >100 weed species and he has a vast experience in developing integrated weed management options based on agronomic approaches (row spacing, seeding rates, weed-competitive cultivars, etc.). Prof Chauhan has more than 20 years of research experience in conducting trials on the improved agronomy of new production systems and integrated weed management options in Australia and >10 Asian countries. Before joining UQ, Prof Chauhan worked at the International Rice Research Institute (IRRI) in the Philippines for seven years. He has a strong collaboration in several countries, including USA, Sri Lanka, India, Nepal, Iran, Pakistan, Nigeria and China. His research interests include weed ecology and biology, herbicide use, management of herbicide-resistant weeds, non-chemical weed management options, integrated weed management systems using agronomic and varietal components, nanoherbicides, tillage systems, and conservation agriculture systems. He is a Speciality Chief Editor with Frontiers in Agronomy and an Associate Editor of Weed Science (Weed Science Society of America). He has published over 350 articles in peer reviewed journals and several books and book chapters. He is an Honorary Member of Weed Science Society of America (WSSA) and a life member of International Weed Science Society (IWSS), Asia Pacific Weed Science Society (APWSS), and Indian Society of Weed Science (ISWS).
