Glyphosate Resistant Weeds – Intensifying
by Kent Fraser
Not only are glyphosate resistant weeds spreading geographically, the problem is also intensifying with multiple species now resistant on an increasing number of farms.
US farmers told us that 61.2 million acres of cropland are infested with glyphosate resistant weeds, almost doubling since 2010.
Stratus has asked thousands of US farmers about resistance, with surveys across 31 states over three years. The trends are dramatic:
The explosion of resistance has certainly heightened concern, but American farmers always respond to agronomic challenges! Stratus is conducting a Resistance Management study to see just how U.S. farmers are adjusting their practices to deal with the problem.
Of course, weeds don’t pay attention to borders, so Stratus is also tracking resistance in Canada.
