Farmers face many hurdles when attempting to effectively manage yield-robbing, herbicide-resistant weeds. According to a recent survey of crop advisers, those barriers most often include economics, management complexity and supply constraints, along with the perception that a "silver bullet" will eventually solve the issue.
Katherine Dentzman, an assistant professor of rural sociology at Iowa State University, led the survey effort, which included responses from more than 350 certified crop advisers representing all 50 U.S. states. Overall, about 75% of advisers were moderately or very concerned about helping farmers manage herbicide resistance in the next five years.
"From my own research, growers know what the issues are, and they really want to use all of the best management practices available," she said. "In the survey, that's also what we heard from the crop advisers. They see a high level of awareness of the issue among growers, but they're also seeing growers who are struggling to manage resistance in an optimal way."
The advisers surveyed said one obstacle that makes the herbicide resistance conversation more difficult to broach is that farmers have grown weary of the message.
"There's definitely this fatigue around resistance management," said Dentzman, who began studying farmer perceptions of herbicide-resistant weeds roughly a decade ago. "They've heard it a million times, and it's just exhausting. In the survey, 22% of crop advisers said their customers are tired of hearing about it."
She noted that for many farmers, this fatigue has led to an almost fatalistic attitude where they feel that managing resistance is more complicated, more expensive and more time consuming than they can possibly handle, leading to the belief that a "silver bullet" is the only solution.
"About 18% of crop advisers surveyed said silver bullets were something their customers are constrained by," she said. "I have discovered that a lot of farmers will say that because they feel like there are no other options. They feel like there's going to need to be a silver bullet because they just don't see any other way it's going to happen."
Dentzman added that she's encountered some people who advise growers who feel that they need to "put the fear of God" in them by denouncing any notion of a future silver bullet and chastising them for not taking the issue more seriously.
"That kind of dialog just shuts people down," she said. "It reinforces that fatalistic attitude of 'There's nothing I can do. There's just going to need to be some miracle that comes along and saves the situation.'"
