Farmers have been using the weed killer glyphosate – a key ingredient of the product Roundup – at soaring levels even as glyphosate has become increasingly less effective and as health concerns and lawsuits mount.
Glyphosate is the most used pesticide on U.S. agricultural crops, with the nation using an estimated 287 million pounds in 2016, according to an analysis by the Midwest Center for Investigative Reporting. And sales continue to grow, with market researchers predicting the glyphosate market to grow to $8.5 billion to $10 billion annually by 2021 up from $5 billion now.

Of 400 pesticides used on agriculture crops across the U.S, glyphosate is used at least three times more than all others, according to an analysis of data estimates from the U.S. Geological Survey. The second-most used weed killer in the U.S. is atrazine – with 75.4 million pounds used on U.S. agriculture crops in 2016. In 2016, the Midwest used 65 percent of the nation’s total agriculture glyphosate use on crops.
Normally, Story County soybean farmer Kevin Larson said, he would resolve a dispute with a neighbor privately. Instead, he went to the Iowa Pesticide Bureau in 2017, just like a lot of other Iowans did.
A volatile weed killer linked to cancer and endocrine issues will likely be sprayed on millions more acres of soybeans and cotton across the Midwest and South starting this year. In January, China approved imports of a new genetically modified soybean variety – Enlist E3 soybeans jointly made by Corteva Agriscience, a division of DowDupont and seed company MS Technologies– that can withstand the herbicide 2,4-D. “This is great news for U.S. soybean growers,” said Joseph Merschman, president of MS Technologies in a February press release. “This announcement clears the way for even more soybean growers to experience the high-yielding elite genetics and exceptional weed control offered by the Enlist E3™ soybean system.”
DowAgrosciences declined to comment for this story. The herbicide – 2,4-D – was one of the active ingredients in Agent Orange and has been shown to drift miles away from where it’s applied.

Iowa will not add investigators to handle an increased number of pesticide drift complaints, favoring instead more efficient ways to handle complaint inspections, the state’s chief agriculture officer said. “I’ve got to manage the department of ag within my budget,” Mike Naig, Iowa Secretary of Agriculture and Land Stewardship, said in IowaWatch’s weekly radio program that aired this past weekend. “It’s true, we’ve not seen a budget increase in the pesticide bureau, and I don’t expect to see a dramatic increase in the pesticide budget. So, what we do is look at how to manage the workload with the crew that we have.”
Naig’s comments followed an IowaWatch report on how workloads for Iowa’s eight state investigators who respond to complaints of misused herbicides have more than doubled the past two years. The workload increase went from 110 misuse reports in the 2016 crop year to 249 in the 2018 crop year.
A bill has been introduced in the Iowa Legislature that would increase the fee for a three-year public or private pesticide application certification from $15 to $30 and designate money raised from those fees to the state’s pesticide and administration fund. The fee for commercial applicators would remain at $75. The bill was introduced Feb. 25 and passed its first subcommittee hurdle two days later. It came a month after an IowaWatch story about how recommendations for investigating Iowa’s pesticide application, made by the Iowa State Auditor’s office in a 2012 audit and subsequent reports, had not been addressed.
The IowaWatch.org stories from 2018 that you read most covered a variety of topics: the environment, mental, cultural diversity, agriculture and personal safety from being assaulted. Here they are.
Iowa state Sen. Bill Dotzler has traveled across Iowa’s country roads on his bicycle while training and riding for RAGBRAI. On these rides, he pays attention to farmers spraying pesticides in fields along his routes. “I’ve been out on the roads where you can see sprayers in high winds situations. You know you kind of pedal as fast as you can so you don’t get hit with it,” Dotzler, a Waterloo Democrat, said. But any efforts to add regulations to pesticide spraying in recent years at the Iowa Legislature have not gone anywhere.
Nine of every 10 public school districts in Iowa have buildings within 2,000 feet of a farm field, making students and teachers susceptible to being exposed to pesticides that drift from the fields when pesticides are sprayed. Yet many school officials interviewed for an IowaWatch/Tiger Hi-Line investigation showed little to no awareness on if or how pesticide drift could affect the staff and students in school buildings.
The U.S. Environmental Protection Agency lessened protections for crops and wildlife habitats after Monsanto supplied research that presented lower estimates of how far the weed killer dicamba can drift, according to a review of federal documents. In its final report approving the usage of dicamba on soybeans, the agency expressed confidence that dicamba, new versions of which are made by Monsanto and German chemical company BASF, would not leave the field. The registration covered both herbicides, an EPA spokesperson said. “The EPA expects that exposure will remain confined to the dicamba (DGA) treated field,” the agency wrote in the final registration approving the use of dicamba in November 2016. However, drift from dicamba damaged more than 3.6 million acres of soybeans in 2017, according to data from Kevin Bradley, a professor at the University of Missouri.
