Event will target weed herbicide resistance
The National Resesarch Council and Weed Science Society of America (WSSA) are pooling resources to address the growing threat of weed herbicide resistance in a May 10 event at George Washington University in Washington, D. C.
“A significant contributing factor in the evolution of resistance is the repeated use of a single herbicide mode of action,” says David Shaw, former WSSA president in a WSSA report. "To counter this dangerous trend, we need to move to integrated weed management programs that incorporate a variety of other control methods. Doing so can help us preserve crop yields, herbicide effectiveness and the sustainability of vital agricultural production systems.”
Other WSSA scientists on the program include:
Michael Owen, professor of agronomy at Iowa State University, who will speak on the nature of herbicide resistance in weeds.
Jodie Holt, professor of plant physiology at the University of California-Riverside, who will speak on the epidemiology of herbicide resistance.
Stephen Powles, professor of weed science at the University of Western Australia, who will discuss what his country is doing to combat herbicide resistance.
Harold Coble, agronomist with the U.S. Department of Agriculture (USDA) Agricultural Research Service, who will speak on ways to address the pressing problem of herbicide resistance.
Dale Shaner, plant physiologist with the USDA Agricultural Research Service, who will participate in a panel discussion on impediments to the use of best management practices.
John Soteres of Monsanto Company, chairman of the Herbicide Resistance Action Committee, who will participate on a panel discussing ways to encourage the adoption of best management practices.
Last fall WSSA introduced a free training program on herbicide resistance that is tailored for pesticide applicators, growers, agrichemical retailers, farm consultants and other industry stakeholders. The peer-reviewed materials are currently available here.
