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

Glyphosate resistant waterhemp moving across Ontario
With its method of pollination and resistance abilities, the weed is becoming harder to control
Canada, France head in different directions on glyphosate
Health Canada says it stands by its earlier re-evaluation of the herbicide, finding it safe for labelled use
The Canadian federal health department says it continues to have no concerns about the safety of the glyphosate herbicide after it reviewed eight notices of objection received after it released its final re-evaluation decision on glyphosate in April 2017. The objections were filed with Health Canada in June and July that year by individuals and […] Read more
Edible bean growers could get more weed control options
Ridgetown College research shows that older chemistries can help control glyphosate-resistant weeds in strip till
When the Weed Society of America challenged its members to evaluate weed pressure on field crops, Peter Sikkema found that in Ontario edible beans were most challenged by weed pressure. “The crop I work on that is most affected by weed interference is dry beans,” the professor at University of Guelph’s Ridgetown campus said at […] Read more
Glyphosate drives long-term herbicide changes
Ontario keeps track of detailed herbicide use every five years, which shows how the use of active ingredient has declined
A study of glyphosate use in Ontario shows the herbicide has created significant change in crop management. It shows that while corn and soybean acreage and yield have increased in the province since 1983, the impact of herbicide use per acre has declined, in large part because glyphosate has displaced other herbicide chemistries. Why it […] Read more
Cover crops can be tricky to kill
Cover crops can be important tools to improve soils, but there’s no single control solution
Cover crops can do a lot for the soil, but keeping them from becoming covering weeds requires the right herbicides applied at the right rate — to kill them at the right time. What cover crop is used, too, should be appropriate for the job the farmer wants to accomplish. Why it matters: Cover crops […] Read more
Taking the dicamba cleanse
Experts remind growers to take an active approach to sprayer cleaning, and of the importance of ammonia in removing dicamba residues
The sensitivity of soybeans and other plants to dicamba — a volatile auxin-based herbicide employed in various forms since the 1960s — is extreme. Even trace amounts can cause significant damage to susceptible crops, meaning proper equipment cleaning is critical to avoiding unintended problems. Why it matters: Use of the herbicide will increase with the […] Read more
