Wild oats, which are the biggest weed headache for Canadian farmers, have developed herbicide resistance in 50 to 60 percent of fields.  |  File photo

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

Ray Harrington of Darkan, Western Australia, is the man behind the Harrington Seed Destructor, a machine that pulverizes weed seeds at the harvest stage. He spoke in Lethbridge Aug. 12 and explained the specifics to a group at the Agriculture Canada research centre. This slide shows the pull-type model but Harrington said a combine-mounted version of the destructor has been built and could be available in Canada within five years.  |  Barb Glen photo

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



Sulfoxaflor is a new category of chemical approved for fruit, vegetables, soybeans, barley and canola. Some beekeepers are concerned about its effects on bees.  |  File photo

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


Farmers around the world are expected to use 1.35 million tonnes of glyphosate herbicide by 2017.  |  File photo

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
