After shutting down row-crop use of dicamba for the rest of this growing season, Arkansas has appointed a 21-member task force to look for a long-term solution to the nearly 900 complaints about the herbicide this year. "The task force will attempt to reach consensus on a set of recommendations for the use of dicamba products n Arkansas as quickly as possible in order to provide certainty for the 2018 growing season," said the state Agriculture Department.

A University of Missouri weed specialist says the weedkiller dicamba has damaged more than 2.5 million acres of cropland this year, mostly in the Midwest and South, reports Harvest Public Media. The researcher, Kevin Bradley, says, “I don’t know that we’ve ever in our agricultural history seen one active ingredient do so much damage across one nation like that.”

Due to a procedural error on Tuesday, the Arkansas state plant board will re-vote on Friday on whether to temporarily ban use of the weedkiller dicamba, suspected of drifting out of cotton and soybean fields to damage neighboring crops, reported DTN. Some 167 complaints alleging misuse of the herbicide, mostly along the eastern edge of Arkansas, were filed with the state board as of midday Wednesday.

Faced with 97 complaints of misuse of the weed killer dicamba, the Arkansas state plant board is set to vote today on whether to ban the sale and use of the herbicide on cotton and soybeans for the rest of the growing season, reported DTN.

The European Commission will propose granting glyphosate — the world’s most common weedkiller and the key ingredient in Monsanto’s Roundup — a 10-year renewal of its license. The commission had held off on making the proposal over controversy that the chemical was carcinogenic.

The wine industry contributes an estimated $2 billion to the Texas state economy, but winegrowers say their livelihood is under threat by weedkillers intended for use on genetically engineered cotton. They are not placated by EPA assurances that new herbicides use formulations that are less prone to drift onto neighboring land in the No. 1 cotton state, or that spray rigs will use anti-drift nozzles, says the Texas Tribune.

The largest peach grower in Missouri — Bader Farms — claims Monsanto is responsible for the illegal use of herbicide that damaged its trees over the past two years, said the St. Louis Post-Dispatch. The lawsuit says 37,000 trees were harmed because of herbicide drift from a field where farmers used unauthorized versions of dicamba on crops, which were genetically engineered by Monsanto to tolerate the weedkiller.

The policies of the "Federal Crop Insurance Corporation, a taxpayer-funded insurance program managed by the U.S. Department of Agriculture’s Risk Management Agency (RMA) and administered by a network of private companies,” punish farmers for environmentally-friendly practices, like planting cover crops, says Kristin Ohlson in FERN’s latest story, which was produced with Ensia.

The EPA approved a low-drift formulation by Monsanto of the weedkiller dicamba for use on GE soybeans and cotton during the growing season. Farmers reported dicamba damage to 42,000 acres of crops this year due to use of unapproved, higher-volatility versions of the herbicide on neighboring farms.

Farmers in Arkansas are experimenting with a weed-control tactic from Australia, called narrow windrow burning, to combat weeds that have developed resistance to herbicides. The scorched-earth technique dramatically reduces the weed seeds that sprout in the spring to challenge row crops, says Farm Journal.

In the 20 years since GMO crops were approved for cultivation, U.S. farmers have embraced them almost to exclusion of other seeds while Europe has steadily refused to let them into its fields. The New York Times says its "extensive examination" of U.S. and European farming found that genetic engineering "has not accelerated increases in crop yields or led to an overall reduction in the use of chemical pesticides."

The administrative arm of the European Union opened an in-depth review of the proposed $130 billion merger of Dow and DuPont, identifying its three primary areas of concern as seeds, pesticides and petrochemicals.

Palestinians in the Gaza Strip say that their crops are failing because of herbicides sprayed by Israel along the Gaza-Israel buffer zone, says Aljazeera. It quoted an Israeli Army spokesman who confirmed spraying in the area, citing security reasons.

Monsanto says Bayer isn't offering enough to justify a merger but that it's open to continued talks with the German company. An official at Johns Hopkins' Center for a Livable Future says a merger would "be a real shock to the food system" because of the potential of higher prices to farmers for seeds and agricultural chemicals in a sector undergoing consolidation, reported Marketwatch.

Two researchers at Cornell say the factors behind the decline in monarch butterfly populations are wider spread than the loss of milkweed, their summertime food source. They say the list includes sparse nectar sources in the fall, adverse weather and fragmentation of habitat.
