Grower Survey: Glyphosate Resistance Not Urgent Concern

Survey results published in Weed Technology, a quarterly publication of the Weed Science Society of America, may surprise ag retailers.

The survey results indicate that U.S. growers in general do not feel a sense of urgency when it comes to developing a deeper understanding of the herbicide glyphosate and its relationship to weed resistance.

What makes this 2009 study, “U.S. Farmer Awareness of Glyphosate-Resistant Weeds and Resistance Management Strategies,” especially important is that it is one of only a few that have compiled information on a broad scale about growers’ perspectives on weed management in glyphosate-resistant crops.

Many of the surveyed growers, who grow glyphosate-resistant crops in six states, reported that they were not very concerned about the emergence of glyphosate-resistant weeds. However, the more often glyphosate is used, the more likely glyphosate-resistan weeds will evolve. In fact, many weeds are already resistant, and this has and will continue to have economic ramifications.

The growers also tended to believe they could reduce the likelihood of glyphosate-resistant weed proliferation most effectively by following the glyphosate label’s instructions for use. Fewer understood that tillage and crop rotation are other effective strategies. The growers’ position stemmed from a belief that better herbicides would soon be available to treat glyphosate-resistant weeds. However, because of the time commitment and high costs associated with developing these products, they will probably not be available for several more years.

Although the growers used a variety of publications as sources to keep informed of optimal weed management strategies, inconsistent information presented in these publications may compromise the effectiveness of the results. Therefore, it is critical that life science companies, universities, grower groups, and the government work together to create and disseminate dependable information about the best herbicide resistance management.

Growers must not be complacent when it comes to managing glyphosate-resistant weeds. Their long-term success depends on appreciating and responding to the complexities of these ever-evolving invaders.
