DowDuPont becomes second company to shut down a cellulosic ethanol plant

In another sign of trouble for so-called advanced biofuels, the newly created giant corporation DowDuPont stopped operations at its $225 million cellulosic ethanol plant in Nevada, Iowa, and hopes to find a buyer for the plant with a 30-million-gallon-a-year capacity, said the Des Moines Register. Last December, Abengoa Bioenergy sold its cellulosic plant in Hugoton, Kan., for pennies on the dollar as part of a bankruptcy liquidation of assets.

Arkansas proposes ban on row-crop use of dicamba for 2018

Spurred by nearly 1,000 complaints of crop damage from dicamba this summer, the Arkansas State Plant Board has proposed a ban on using the weedkiller on cotton and soybeans from April 16 to Oct. 31 — effectively the entire growing season. The EPA also is considering restrictions on the use of dicamba, which was touted as a new tool against invasive weeds resistant to other herbicides but has also been blamed for damaging more than 3 million acres of soybeans nationwide.

Arkansas plant board faces opposition to April 15 dicamba cutoff

The Arkansas State Plant Board, which is scheduled to decide today whether to limit use of the weedkiller dicamba in 2018, is getting advice that ranges from a letter that suggests permitting use of the herbicide as late as May 25 to a petition against any limits at all, says broadcaster KARK. A task force convened at the direction of Gov. Asa Hutchinson has recommended an April 15 cutoff for using dicamba on cotton and soybeans in the state next year.

Dow asks U.S. to ignore EPA risk studies of three pesticides

Pesticide makers sent letters to federal regulators asking them to "set aside" agency research into the risks to endangered species from three organophosphate pesticides — chlorpyrifos, diazinon and malathion — says The Associated Press. Dow Chemical (whose chief executive "is a close adviser" to President Trump), FMC Corp. and Adama, sent letters to the EPA and the Commerce and Interior Departments to argue the studies should not be used.

To smooth merger, DuPont sells part of its crop-protection unit to FMC

In a multibillion-dollar asset swap, Dow is selling part of its crop protection operation to FMC and and picking up nearly all of FMC's health and nutrition business. As part of the deal, FMC will acquire a Dow agricultural research center in Newark and turn it into the global research and development center for FMC, which is based in Philadelphia, says the Wilmington News Journal.

EPA nears deadline for decision whether to ban chlorpyrifos

Last summer, a federal appeals court gave the EPA until March 31 — this Friday — to decide whether to ban or allow continued use of the insecticide chlorpyrifos, used on more than 50 crops, including alfalfa, corn, peanuts and wheat. Mother Jones says the new administration "will have to make a momentous choice" in its early days in office.

EU clears Dow-DuPont merger with requirement to sell some assets

The administrative arm of the European Union approved the merger of Dow and DuPont based on their promises to divest some assets, says Deutsche Welle. It was the first decision on a wave of proposed consolidations that would reshape the seed and ag-chemical sector into a "big three," down from the six firms that now compete.

Ag-merger wave looks like a ‘tsunami,’ says Senate Judiciary chairman

The seed and ag-chemical industry "is seemingly on the precipice of a significant structural transformation," says Senate Judiciary chairman Charles Grassley in remarks written for today's hearing on consolidation in the sector. Five of the "big six" companies are involved in mergers while two Canadian companies are combining to form the world's largest fertilizer company.

Antitrust regulators are collaborating on ag-merger wave

Ahead of a Senate Judiciary Committee hearing on consolidation in the seed and ag chemical sector, the Justice Department and the Federal Trade Commission say they will consider the combined impact of mergers as well as the import of each deal. If they go forward, the mergers would result in three dominant companies in the sector instead of the current six.
