Waiting and weeding are keys to organic success

After six years, this organic farmer is seeing reduction in some weeds

By
Reading Time: 4 minutes It can sometimes be comforting for an organic farmer if the view of their field from the roadway shows an absence of green growth between the rows of corn or soybeans. But according to the presenter of a recent Guelph Organic Conference session entitled “Avoiding Field Crop Disasters,” this illusion can often hide the troubling […] Read more

Bayer announces new herbicide mode of action

The broadleaf herbicide will be the first new mode of action in 30 years

By
Reading Time: 3 minutes A new herbicide molecule, a different approach to short stature corn and XtendFlex soybeans are three projects in the Bayer CropScience development pipeline that could have an impact on farms. Why it matters: There is increasing resistance to current herbicides so a new mode of action will be welcome. Bayer announced the new herbicide and […] Read more

New option launched to manage resistant weeds in soybeans

Enlist E3 soybeans are resistant to multiple herbicides meaning more options to deal with weed issues

By
Reading Time: 2 minutes Ontario farmers will have more options to manage herbicide-resistant weeds with the launch of Enlist E3 soybeans in Canada. E3 soybeans are resistant to 2,4-D, glyphosate and glufosinate herbicides. That provides more flexibility when spraying fields that have resistant weeds, which are becoming an increasing problem in Ontario, especially when it comes to glyphosate. Why […] Read more

Glyphosate resistant waterhemp moving across Ontario

With its method of pollination and resistance abilities, the weed is becoming harder to control

By
Reading Time: 3 minutes Glyphosate-resistant waterhemp is now present in seven counties across Ontario. Huron, Wentworth and Haldimand are the three most recent counties where it was found, in addition to the previous Essex, Lambton, Chatham-Kent and Middlesex counties. Seeds were harvested harvested in fields in these counties last fall, planted in a greenhouse to overwinter and tested once […] Read more

Plant stress makes early-season weed control critical

Research shows corn and soybeans can sense the presence of weeds even before emergence

By
Reading Time: 4 minutes Do you get anxious about weeds in the field? Your crops sure do, and according to new research, yield reductions from early-season weed pressure can happen extremely quickly. Research in the late 1980s established the significant yield impacts caused by weeds if they are not properly controlled early in the growing season, says Clarence Swanton, […] Read more

Evaluating mechanical weed control options

Researchers found that when two methods are used, weed control improves

By
Reading Time: 3 minutes With the rise of herbicide resistant weeds, researchers at the University of Saskatchewan are looking into alternative weed control methods focused on in-crop mechanical tools to give growers new management options. Why it matters: Farmers are looking for alternative solutions to deal with herbicide resistant weeds that are becoming tougher to control and are affecting […] Read more
