New Rule To Cut Down On Dicamba Drift Damage


Our 2018 KELOLAND News Investigation, “Dangerous Dicamba Drift,” looked into how a new formula of vaporized weed killer spreads to conventional crops.

Drift of the herbicide damaged everything from specialty crops to organic farms to gardens and bees, even days after it was sprayed.  A quarter-million acres were estimated to be damaged by Dicamba drift in 2017 in the state.

Now South Dakota’s Department of Agriculture has established a new cutoff date of June 30 for farmers spraying Dicamba products.   That follows suit with Minnesota, where the cutoff date for spraying is June 20.

Dicamba can cause more destruction to non-resistant crops after soybeans reproduce later in the summer.

South Dakota’s new rule is now stricter than the EPA’s.

Dicamba maker, Monsanto, has said it disagrees with cutoff dates.

Shortly after our 2018 KELOLAND News investigation, South Dakota classified Dicamba products as restricted-use pesticides.
