Welcome to the world of gene flow

Preventing gene flow from GM crops may prove a tough challenge, partly because knowledge is limited on exactly how and to what extent genes transfer from one species to another, or even within the same species.

Gene stacking gets close scrutiny

Opinions on gene stacking appear divided between those who love the concept and those who are nervous or even downright scared of its implications.

Not your father's atrazine?

Weeds that quickly developed resistance to triazine herbicides are still around today, but growers changed the way they used the products, such as the corn herbicide atrazine. Thus, over 40 years later, the chemical remains a key component of corn growers' weed control programs.

Crop and herbicide rotations keep canola clean

While growers of glyphosate-tolerant soybeans, corn and cotton elsewhere in North America fret about the future of their favourite herbicide, Canada's canola growers have so far seen no evidence of glyphosate-resistant weeds invading their fields.

Resistant weeds surge on Prairies

Here on the Prairies, Group 1 resistance is spreading rapidly, Group 2 resistance has made its way into 19 species including "all kochia populations" and reports of weeds controlled by neither Group 1 nor 2 are also increasing.

Resistant weeds take centre stage

After years as an "also-ran" topic at crop production meetings, herbicide-resistant weeds take on a high profile this week at a new conference devoted to the threat they pose to farmers and food production.

New herbicides head through the pipeline

Don't expect to see productivity gains in crops at levels witnessed in the 1970s and '80s, but current economic conditions are seen as spurring substantial investment in crop protection R+D.

Glyphosate-resistant weeds ready to strike

As other herbicide groups fall prey to resistant weeds, it's feared that glyphosate-tolerant crop varieties may soon become victims of their own success in both the field and the marketplace.

Crop specialization breeds weed resistance

Crop rotations with little or no variety, or where the crops duke it out with the same weeds year after year, may end up leaning too heavily on certain herbicides to sustain their usefulness.
