As Paul Bonarrigo watched his grapevines dwindle, he was confident that heavy-duty herbicides, probably sprayed on crops by a nearby farmer, were drifting into his vineyards. …

Other Texas winegrowers have seen similar damage, and they blame it on dicamba and 2,4-D, two high-volatility herbicides commonly used on cereal crops, pastures and lawns. Now, the state’s vintners are alarmed that use of the chemicals may soon expand to include 3.7 million acres of cotton fields in the High Plains, where cotton is being invaded by weeds immune to the Roundup pesticide long used.

. . . .

The U.S. Environmental Protection Agency recently approved Monsanto’s new formulation, called XtendiMax with VaporGrip Technology, which contains dicamba. The agency has also proposed to register Enlist Duo, a Dow AgroSciences formulation that contains 2,4-D. 

Both formulations will be used on cotton crops planted with seeds genetically engineered to resist the spray. …

. . . .

But regulators say the new pesticides are formulated to drift less than old versions….

. . . .

But Irwin said it is unlikely farmers will buy the new low-volatility formulations because they are the most expensive. Farmers will probably instead stick to old dicamba and 2,4-D pesticides when they plant genetically modified seeds.
