Arkansas on Verge of Banning Dicamba During Growing Season

Arkansas Defies Monsanto, Moves to Ban Rogue Weedkiller

This was the first year that farmers were allowed to spray it on soybean and cotton fields. (Some farmers did use dicamba illegally last year, provoking disputes between farmers that in one case, led to murder.) Many farmers embraced the new tool. But it quickly turned controversial: Farmers couldn't seem to keep dicamba confined to their own fields.

The problem was worst in Arkansas, where almost 1,000 farmers filed formal complaints of damage caused by drifting dicamba. But the rogue weedkiller has hit fields across soybean-growing areas from Mississippi to Minnesota.

According to estimates compiled by weed scientist Kevin Bradley at the University of Missouri, at least 3 million acres of crops have seen some injury. Most are soybeans that aren't resistant to dicamba, but vegetable crops like watermelons, fruit trees and wild vegetation have been injured as well. The dicamba vapors didn't typically kill the plants but left behind curled leaves and sometimes stunted plants.

"There is no precedent for what we've seen this year," says Bob Scott, a weed specialist with the University of Arkansas.

The Arkansas State Plant Board now has taken the lead in cracking down on the problem. On Thursday, it voted unanimously to ban the use of dicamba on the state's crops from mid-April until November. This amounts to a ban on the use of dicamba in combination with Monsanto's genetically engineered crops. It's not a final decision: The governor and a group of legislative leaders have to sign off on the Plant Board's regulatory decisions, but they usually do so. That won't happen, however, until after a public hearing set for Nov. 8.

The board also approved a steep increase in fines — up to $25,000 — for farmers who use dicamba and similar herbicides illegally.
