Group announces Weed Science Summit


The Weed Science Society of America announced it will co-sponsor an upcoming scientific summit on how to manage herbicide-resistant weeds – a costly and growing problem threatening crop production across the U.S. and around the globe. 

The May 10 event is being organized by the National Research Council, the operating arm of the National Academy of Sciences, and will be held at George Washington University in Washington, D.C. 

Several WSSA members will deliver presentations or participate in panel discussions.  Among them is David Shaw, former president of WSSA and immediate past chairman of its Herbicide Resistance Education Committee.  He will address best management practices that can combat herbicide resistance. 

“A significant contributing factor in the evolution of resistance is the repeated use of a single herbicide mode of action,” Shaw says.  “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.”
