Synthetic auxin herbicides, with their complex mode of action, have long played an important role in weed management. Indeed the way auxin herbicides bind to receptors in plant cells alters growth in susceptible species, thereby enabling weed control.
Daniel R. Kittle, Ph.D., vice president, Research and Development, DAS said “The collaboration with the University of Warwick provides important insights into the fundamental interaction between plants and our newest innovations in auxin herbicides.”
Working alongside Dr Kittle, Richard Napier, Ph.D and Professor in the School of Life Sciences, University of Warwick added “There is one natural auxin which controls plant growth. There are also many synthetic auxins and these work as herbicides by overpowering the natural system. Our recent work has shown that not all auxins are equal. The new arylpicolinates prioritise a different target site compared to natural auxin and other auxin herbicides, and they bind to this site with high affinity.”
