According to the St. Louis Post-Dispatch, Arkansas’s Plant Board passed restrictions that would only permit the use of certain types of dicamba, and will only allow BASF’s Engenia dicamba herbicide to be applied April 15-Sept. 15. It will also be eligible for use on Monsanto’s dicamba-tolerant cotton and soybean varieties.

The St. Louis-Dispatch reports:

Crop damage from the last growing season is done, but Missouri and Arkansas lawmakers are taking steps that aim to prevent future devastation from dicamba, the herbicide widely blamed for a rash of illegal spraying that sowed financial pain and discord in farming communities across the region.

Arkansas set a bold example last week, when the state’s Plant Board passed restrictions that would only permit the use of certain types of dicamba and would only allow one variety to be applied from April 15 through Sept. 15 — when warm temperatures make the herbicide more susceptible to forming vapor and drifting to nearby fields, where it can damage any crops that aren’t genetically modified to tolerate it.

Interestingly, the variety approved for use throughout the growing season in Arkansas is Engenia, from chemical company BASF, and not Xtendimax, the new herbicide from Creve Coeur-based Monsanto. Xtendimax, which Monsanto has touted as being less volatile , was not approved for use by the Environmental Protection Agency until late 2016 even though the company started selling crop varieties resistant to the herbicide in 2015.
