“Diverse tactics” for weed control other than herbicides
On the same day EPA approved the new Dow herbicide, USDA listed four steps it will take in response to the spread of herbicide resistant weeds.
EPA approves Dow weedkiller combo of 2,4-D and glyphosate
The EPA cleared the Dow weedkiller Enlist Duo, which contains the herbicides glyphosate and 2,4-D, for use on genetically engineered corn and soybean in six Farm Belt states. "This action provides an additional tool for the agricultural community to manage resistant weeds," it said. EPA will decide later whether to register the weedkiller for use in the rest of the major corn and soybean states. On Sept 17, USDA approved the GE corn and soybean strains created by Dow to tolerate the herbicide.
USDA approves Dow corn, and soy strains that resist 2,4-D
The Agriculture Department approved for sale two soybean varieties and one corn variety genetically engineered by Dow to tolerate the weedkiller 2,4-D, a widely used herbicide. The varieties would be an alternative to Monsanto's GE crops that resist glyphosate. There are reports of "superweeds" that survive spraying with glyphosate. The Center for Food Safety, a foe of GE crops, said it "will pursue all available legal options to stop commercialization of these dangerous crops." Opponents say 2,4-D poses health and environmental risks, including its own version of herbicide-resistant weeds.
Tenacious herbicide-resistant weed is Farm Belt menace
Rapidly spreading palmer amaranth is the headliner among a list of 16 types of weeds that have developed resistance to glyphosate, one of the most widely used herbicides.
Trade ruling suggests weedkiller dumping hurt U.S. market
The U.S. International Trade Commission ruled, in a 4-0 vote, there was a reasonable indication that domestic herbicide manufacturers were hurt by dumping of imported 2,4-D weedkiller from China and India. The ITC vote allows the Commerce Department to continue its investigation of the imports.
