A Canadian toxicologist says the World Health Organization made a critical scientific error in its decision to classify glyphosate as a probable carcinogen. A panel of experts with the WHO’s International Agency for Research (IARC) on Cancer released a report March 20 on five pesticides, including glyphosate, the most widely used pesticide in the world.

Aussies take time during harvest to fight weeds
Herbicide resistance | With few alternatives, Australian farmers crush or burn weed seeds
Herbicide resistant weeds affect 40 percent of cropland on the Prairies, according to rough estimates. However, Canadian farmers are still able to combat the problem before it gets as bad as conditions in Australia, where virtually every weed is assumed to be herbicide resistant. Michael Walsh of the Australian Herbicide Resistance Initiative focuses all his […] Read more
Inventor targets weed seeds
Ray Harrington considered catching, carting, cremating and cooking weed seeds to control the herbicide resistant varieties that were plaguing farmers across Western Australia. He settled on a fifth C: crushing. Now the developer of the Harrington Seed Destructor is testing a combine-mounted model that will replace the prototype pull-behind unit that first gained attention in […] Read more

The department said it received more than 8,200 comments on the potential impact of this new technology. It also received petitions signed by more than 400,000 people, mostly […] Read more
Entomologist responds to furor over sulfoxaflor approval
Beekeepers, environmentalists and the public should take a breath before passing judgment on a new insecticide, says an American entomologist. In early May, the U.S. Environmental Protection Agency approved the registration of sulfoxaflor as a foliar spray for fruit, vegetables, soybeans, barley and canola. Dow Agro, which developed sulfoxaflor, said the chemical is part of […] Read more
Better water makes better glyphosate
Better burn off | High quality water provides a strong foundation for spring weed control
Farmers need to pay attention to their water when spraying glyphosate, says Chelsea Norheim of Rack Petroleum in Biggar, Sask. “With all spray solutions, 99 percent of what you spray out is water,” the agrologist said. “It only makes sense that water should be the first thing you should be looking at in terms of […] Read more
Glyphosate demand expected to double
Global demand for glyphosate may double over the next five years as farmers switch to no-till agriculture and use more inputs, says a market intelligence firm from California. In a recent analysis of the glyphos-ate industry, Global Industry Analysts (GIA) of San Jose, California, predicts that farmers around the world will use 1.35 million tonnes […] Read more
