Farmer to Farmer Communication Can Help in Dicamba System Success



What is the future of dicamba after a first-year rollout and drift damage that followed? University of Missouri weed scientist, Dr. Kevin Bradley says there’s never been a problem like this in U.S. agriculture and the damage done this past growing season was significant.

“I think that we all recognize that there’s way more that actually happens that isn’t turned in to the departments of agriculture, and so we felt like we wanted to capture that,” Bradley said. “Somewhere around 3.5-3.6 million acres is what the damage totals in 2017.”

While physical drift of the product itself has been a problem, improper tank cleaning has also been found to be an issue. It doesn’t take much leftover dicamba in the tank to do crop damage.

Temperature inversions with a volatile product can cause drift, and Bradley says there shouldn’t be any more night time spraying of dicamba, which is part of the new label requirements.

Jay Magnussen is a farmer and full-time agronomist in northwest Iowa. He says dicamba is not an easy product to use correctly. As an agronomist, he doesn’t want to spend time next summer walking through damaged fields. One way to move forward in the dicamba debate is communication between farmers.

“Like Roundup we’re not going to have all the fields in the neighborhoods be Roundup, so we can pretty much just let it spray everywhere. We’re going to have to watch because we’re going to have conventional beans, we’re going to have Liberty beans. We’re going to have four different technologies that we have to be aware of and watch out for our neighbors. Here in northwest Iowa we had a really good adaptation to flagging our fields. There were four different types of flags that were put next to fields so that we could have farmers and their neighbors talk to each other and know what was planted in the fields before making a post application to control our weeds.”

It’s important for applicators to remember the new dicamba herbicide label requirements include training before the next spraying season begins.
