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
Interest wanes in biopesticides, says scientist
A variety of roadblocks can impede commercialization of biological crop protection products, making them too expensive
Glacier FarmMedia – Biopesticides aren’t ready to compete with synthetic pesticides in broad scale agriculture, said a retired Agriculture and Agri-Food Canada scientist. Research into biopesticides has waned in the […] Read more
Minimizing spray drift on fields
Here are some ways to help keep your pesticides on target

Opinion: The many tools of agriculture
Glacier FarmMedia – Everything changed for agriculture after the Second World War. As the world went to war, the sector was largely driven by horsepower. By war’s end, it was […] Read more
Study shows amines can go airborne
Science Notes: Finding may help explain how dicamba drift occurs
Dicamba drift, the movement of the herbicide off crops and through the atmosphere, can result in unintentional damage to neighbouring plants. To prevent dicamba drift, other chemicals, typically amines, are […] Read more
Weed management brings high return on investment in dry beans
Researchers evaluate costs and tank mixes for optimal control
Dry beans are extremely sensitive to weed interference and researchers have now quantified the value of weed management for Ontario growers. “Our data shows there is a 636 per cent […] Read more
