BISMARCK, N.D. (NewsDakota.com) – The BASF, Monsanto and DuPont companies are now offering online training sessions for applicators of the controversial weed killer dicamba in North Dakota.

New federal rules classify dicamba as a restricted-use herbicide, and applicators need training.

NDSU Extension Educator Randy Grueneich said the new rules are in response to complaints of dicamba drift damaging neighboring crops last year.

State Agriculture Commissioner Doug Goehring says the online training is for potential applicators who couldn’t attend training sessions held earlier this year. Links to the online training are also available on the state Agriculture Department’s website.
