Dual-herbicide seeds to be Monsanto’s biggest GE launch
After a decade of development, Monsanto anticipates its genetically engineered Xtend soybean and cotton varieties will be its "largest biotech trait launch...with six times the number of varieties" that it offered in a previous set of GE strains.
Monsanto experiments again with GE wheat
More than a decade after pulling the plug on genetically engineered wheat, Monsanto is working again on biotech wheat, says the St Louis Post-Dispatch after visiting a research center run by the agribusiness giant.
USDA approves GE cotton and soy that tolerate dicamba
The government approved cultivation of genetically engineered cotton and soybean varieties from Monsanto that tolerate the weedkillers dicamba and glufosinate. So-called super weeds that are resistant to glyphosate, a widely used herbicide known as Roundup, have prompted work on biotech plants that can be matched with other herbicides.USDA said a Federal Register notice of its decision was scheduled to appear on Tuesday, the effective date for deregulation of the new Monsanto strains.
New pesticide-tolerant crops close to USDA approval
Cotton and soybean varieties genetically engineered by Monsanto to tolerate the herbicide dicamba should be approved for use by farmers, said USDA in issuing its final environmental impact statement (EIS) on the strains.
“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.
“Superweeds” – prolific competitors and spray-resistant
Herbicide-resistant "superweeds" are the result of "over-reliance on a single class of herbicides," says the Weed Science Society of America.
Soil-savings from GE crops is a myth, says green group
Genetically engineered crops get undue credit for reducing soil losses on cropland, says the Environmental Working Group. In a three-page analysis, EWG says the credit really should go to so-called conservation compliance and the Conservation...
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.
“Super weeds” bring resurgence of mechanical cultivators
Row-crop cultivators are being put to work because of the emergence of herbicide-resistant "super weeds," says DTN, "something of a renaissance" for mechanical weed control. Cultivators went into decline with adoption of limited-tillage and herbicides.
