Editorial: In the weeds

By
Canada has a brewing weed problem, and we’re not talking about the looming legalization of cannabis. This is an older problem, but with a modern twist, in the form of constant selection pressure from chemical control products and the resulting herbicide-resistant weeds. Manitoba farmers have the dubious distinction of being among the first in the

ON THE GROW: Herbicide resistance is spreading quickly

Manitoba Agriculture is warning about new and looming threats when it comes to resistant weeds

By
Manitoba’s provincial weed specialist is urging a harder line on herbicide resistance. “Zero tolerance is really where you need to be,” Tammy Jones of Manitoba Agriculture said. “Controlling your escapes. Control them with mowing; control them with tillage. If you really want to, control them with hand weeding, but if you have resistant wild oats

Tight crop rotations in the hot seat

Rotations were a major point as discussions turned to blackleg during this year’s BASF Knowledge Harvest

By
It’s all but impossible to eliminate sclerotinia and blackleg from the field, but it’s also a mistake to assume crop genetics alone will manage the problem. BASF technical service specialist Colleen Redlick said farmers need to broaden their approach during the BASF Knowledge Harvest in Brandon earlier this winter.
