Crop biological clocks show spraying success affected by time of day
Researchers found that biological processes in plants can determine spray success
Glyphosate out as dry bean desiccant
Bean buyers say that continuing the practice isn’t worth the market risk
The days of using glyphosate as a desiccant on dry beans are coming to an end. Canadian dealers of dry beans, such as white, cranberry, navy and pinto beans, have […] Read more

Jar tests, reading the label and asking trusted advisors are good steps
Farmers need to know whether the products they’re putting into their sprayer tanks will get along or whether they risk plugged nozzles, crop injury and reduced weed control, provincial extension […] 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
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 […] Read more
Glyphosate resistant waterhemp moving across Ontario
With its method of pollination and resistance abilities, the weed is becoming harder to control
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, […] Read more
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 […] 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. […] 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 […] 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 […] 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 […] Read more
