Unique Herbicide Binding Pattern Discovered Via Dow AgroSciences and University of Warwick Collaboration

Business Wire
Synthetic auxin herbicides have played an important role in weed
management for decades with a highly effective yet complex mode of
action. Dow AgroSciences, a wholly owned subsidiary of The Dow
Chemical Company (NYSE: DOW), collaborated with the University of
Warwick, United Kingdom, to discover unique attributes of this
important class of herbicides. Findings were recently shared at the
International Weed Science Congress in Prague as well as the
International Conference on Plant Growth Substances in Toronto.

The research highlighted receptor-binding uniqueness of Dow
AgroSciences’ new arylpicolinate herbicides, including Arylex™
active and Rinskor™ active, compared to other commercial auxin
herbicides. Richard Napier, Ph.D., plant signaling expert and
professor in the School of Life Sciences, University of Warwick,
was the key cooperator who identified these unique differences. The
way auxin herbicides bind to receptors in plant cells alters plant
growth in susceptible species, leading to weed control.
“Since the 1950s, Dow AgroSciences has successfully launched a
number of synthetic auxin herbicides that provide weed control
solutions to farmers globally,” said Daniel R. Kittle, Ph.D., vice
president, Research and Development, Dow AgroSciences. “The
collaboration with Dr. Napier provides important insights into the
fundamental interaction between plants and our newest innovations
in auxin herbicides.”
“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 with Dow
AgroSciences has shown that not all auxins are equal,” said Napier.
“The new arylpicolinates prioritise a different target site than
both the natural auxin, and other auxin herbicides, and they bind
to this site with high affinity.”
Arylex and Rinskor are the first members of the new
arylpicolinate class of auxin herbicides and are effective new
tools for managing weed resistance at low use rates while providing
favorable environmental fate, toxicological and ecotoxicological
profiles.
