Peter Sikkema told edible bean growers that 2,4-D is a glyphosate-resistant Canada fleabane control option, if the treatment is registered.

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

Over 30 years, the active ingredient volume of herbicide applied on crops has declined in Ontario, mostly because glyphosate 
is applied at lower rates than the herbicides it replaces.

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

Off-target damage from dicamba use in the United States has created a major issue for farmers and for Monsanto, which markets the XTend trait in soybeans. The field above appears unscathed.

Dicamba drift problems continue in farm states

Fewer instances of dicamba drift onto non-target crops are being reported this year in the United States, but it continues to divide agriculture community

Aaron Hager has seen many changes in American agriculture in his 25 years at the University of Illinois. As an extension specialist and weed scientist, he saw the introduction and controversy around genetically modified crops and the emergence of herbicide resistant weeds. But nothing compares to the battle and nastiness over the last 12 months […] Read more

Kris McNaughton, right, is a research associate at the University of Guelph’s Ridgetown Campus.

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
