Staying on-target: How seed tech and weed type factor into spraying
Herbicide resistance and seed technologies making spray decisions complex
Seed mills strike back at weed resistance
Researchers have seen up to 95 per cent control of resistant weed biotypes
Weed biotypes have an incredible capacity for developing resistance to chemical products and growers are having a tough time keeping up with the changes. Some farmers are now battling weed […] Read more
How intensive agriculture turned a wild plant into a pervasive weed
Science Notes: Herbicide resistance continues to challenge growers
New research in Science is showing how the rise of modern agriculture has turned a North American native plant, common waterhemp, into a problematic agricultural weed. An international team led by researchers […] Read more
Research team looks at sandblasting-style weed control
Projectile method needs work to tackle between-row growth
A plot of white beans at Agriculture and Agri-Food Canada’s (AAFC) Harrow research farm is part of a new four-site study taking a sandblasting-style approach to weed control in Canadian […] Read more
Fine-tuning the advice on herbicide-resistant fleabane in soybeans
Diversifiying weed control options is important, especially with glysophate costs high
As the incidence of herbicide-resistant Canada fleabane rises in central and eastern Ontario to match the southwest, so too does the awareness that targeted tank mixes and lengthened crop rotations […] Read more
Managing herbicide-resistant weeds in corn
Planning and variety in rotations is a large factor, but cover crops and herbicide programs help too
Herbicide resistant weeds in all crops are a continuous concern, and for corn, these can be reduced with effective management practices. “The whole strategy [of weed control] is going to […] Read more
Group 27 herbicide resistance arrives in Canada
Mesotrione-resistant waterhemp confirmed in Quebec
A persistent and fiercely competitive weed that has developed resistance to several herbicide groups since its arrival in Canada is now the first in the country to fight off a […] Read more
Using glyphosate wisely
Glyphosate breaks down in the soil but buildup is shown to affect phytoplankton
Researchers from the University of Quebec say farmers might want to use glyphosate more sparingly — and for reasons beyond herbicide resistant weeds. Why it matters: Glyphosate may be comparatively […] Read more
Using technology to pinpoint problem weeds
U.K. researchers create inexpensive, in-field herbicide resistance test tool
Britain’s island geography has been a major barrier for invading forces throughout history, but it’s not so effective at stopping the spread of invasive weeds. That’s why United Kingdom researchers […] Read more
Bayer announces new herbicide mode of action
The broadleaf herbicide will be the first new mode of action in 30 years
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. […] Read more
