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

Evaluating mechanical weed control options
Researchers found that when two methods are used, weed control improves
Weed survival can be predicted via imagery
Researchers using imagery to predict viability of Palmer amaranth
Researchers are putting imaging technology to work to improve weed management practices. Maor Matzrafi of the department of Plant Sciences at the University of California, Davis, has been evaluating the use of hyperspectral imaging technology to assess germination and herbicide response in Palmer amaranth. Why it matters: Weed resistance to glyphosate, a broad spectrum herbicide, […] Read more
North Dakota still on lookout for Palmer amaranth
CNS Canada –– Officials in North Dakota continue to hunt down suspicious plants in a bid to keep the aggressive weed Palmer amaranth from establishing there. Palmer amaranth, a pigweed species, made its first confirmed appearance in North Dakota last month, in a soybean field in McIntosh County, in the south-central area of the state. […] 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
Crop scouting with your smartphone
Smartphone app uses machine learning to automatically identify crop diseases
An app that identifies weeds, insect damage and diseases could change the way crop scouting works. “The reality in field crop scouting for pests today is that looking for disease, weeds and insects is done often with textbooks and apps that make use of manual menus and you compare pictures,” said Warren Bills, business development […] Read more
How weeds outsmart you
Herbicide resistant weeds proliferate in unexpected ways, making scouting more important than ever
For two scorching-hot days in July, farmers and crop consultants attending the University of Guelph’s Diagnostic Days event at Ridgetown College heard about the birds and bees – of herbicide resistant weeds. A session hosted by Dave Bilyea, research technician at the Ridgetown campus, reviewed the state of herbicide resistance in Ontario and across North […] Read more
Weedy conversations
A new inexpensive tool has emerged in the fight against weed resistance
In a newly released study, scientists at the University of Illinois and USDA’s Agricultural Research Service offer a new tool to fight herbicide resistant weeds that is not only highly effective, it’s free. All it costs is a conversation. Waterhemp, a weedy nemesis of corn and soybean farmers, has developed resistance to multiple herbicide modes […] Read more
VIDEO: Building awareness for emerging weeds
As Ridgetown College’s weed science technician, Dave Bilyea sees a lot of weeds, often brought to him by farmers and rural landowners with questions about what they’re seeing and whether the weed is a concern. Bilyea set up a display of many of those weeds at the Southwest Ag Conference in Ridgetown this year and […] Read more
Destroying weeds – at harvest
The Harrington Seed Destructor is showing some potential as a way to manage weeds without chemicals – but will it work on Ontario weeds?
Combines and harvest practices in general are great weed seed distribution systems. Think of all those weeds going in the front of the combine and then blowing out the back, all over the field. But what if you could destroy most of those weed seeds before they hit the ground? Canadian research on an Australian […] Read more
Cannabis firm Aurora in talks to buy both CanniMed, Newstrike
Toronto | Reuters — Canadian marijuana producer Aurora Cannabis is in talks with rivals CanniMed Therapeutics and Newstrike Resources to buy both businesses in a friendly deal that would create the nation’s top weed company, people familiar with the matter told Reuters on Friday. The deal signals an easing of tensions following an offer in […] Read more
