Dicamba

Pesticides are all over, from backyard gardens to cornfields. While their use doesn’t appear to be slowing, concern over drift and the resulting effects on health is driving research — and more worries.

Those concerns are bringing pesticides to a different venue: courtrooms.

Farmers in a federal class-action lawsuit filed two main complaints this week against agro-chemical giants Monsanto and BASF regarding the herbicide dicamba, which is blamed for millions of acres of crop damage, especially to soybeans, over the last couple years.

Farmers Face Tough Choice On Controversial Weed Killer Dicamba

Jeff McGrew stood in line with about 30 other western Kentucky farmers awaiting certification that they’ve been trained to apply the herbicide dicamba. The two-hour session explained the Environmental Protection Agency’s new restrictions on use of the controversial herbicide.

The session left McGrew uncertain about whether to use the spray.

“I'm undecided right now but I'm leaning towards not spraying it,” he said. “I don't think in our area we're going to have much of any place that there will be enough area that we won't have buffer zones or other sensitive crops and I'm not sure that it's going to work out for us.”

Lawsuits filed in Arkansas, Illinois, Kansas and Missouri against the makers of the herbicide dicamba will be centralized in the federal court in St. Louis.

The Associated Press reports that the U.S. Judicial Panel on Multidistrict Ligitation decided Thursday to centralize the 11 cases, which allege the herbicide caused significant damage to soybean crops.

In the hopes of not repeating a problematic year for soybean crops, farmers across the U.S. are deciding how best to protect their crops and their livelihood next year from drift damage caused by the weed killer dicamba.

Illinois Pesticide Retailers Detail The Effects Of Likely Dicamba Drift

More than 100 Illinois pesticide retailers reported the weed killer dicamba drifted and damaged soybeans even when it was sprayed in good conditions, according to a recent industry survey.

There will be new restrictions on the weed killer dicamba for the 2018 growing season, the U.S. Environmental Protection Agency says.

The broadly defined restrictions, similar to what the state of Missouri imposed over the summer, were announced Friday in a news release. The EPA says it reached an agreement with agriculture giants Monsanto, BASF and DuPont on ways to tamp down on dicamba drift, which has been blamed for destroying or damaging millions of acres of crops in the United States.

Weed Killer Dicamba Eyed In Oak Tree Damage Across Iowa, Illinois And Tennessee

As soybean and cotton farmers across the Midwest and South continue to see their crops ravaged from the weed killer dicamba, new complaints have pointed to the herbicide as a factor in widespread damage to oak trees.

Monsanto and BASF, two of agriculture’s largest seed and pesticide providers, released versions of the dicamba this growing season. The new versions came several months after Monsanto released its latest cotton and soybean seeds genetically engineered to resist dicamba in 2016. Since then, farmers across the Midwest and South have blamed drift from dicamba for ruining millions of acres of soybeans and cotton produced by older versions of seeds.

Now, complaints have emerged that the misuse of dicamba may be responsible for damage to oak trees in Iowa, Illinois and Tennessee.

Regulators in Arkansas have proposed to effectively ban farmers from using a controversial weedkiller produced by Monsanto that is thought to be destroying crops after drifting in the wind.

The Arkansas State Plant Board proposed a ban on using the herbicide dicamba on cotton and soybeans from April 16 to October 31, essentially the entire growing season. (PDF)

The herbicide dicamba is thought to have been the culprit in more than 3 million acres of damaged soybeans across the country, destroying plants and leaving farmers out millions of dollars in crops.

The chemical has been in use for decades, so why is it today apparently causing farms so much damage?
