Specialists tied in knots over aggressive plant

Friends don’t give friends knotweed. That is advice Alberta Agriculture weed specialist Nicole Kimmel says gardeners should adopt.

Weed of the Week: wild buckwheat

Of the 10 most unwanted weeds in Western Canada, wild buckwheat is No. 3, according to producers. In Alberta, they say it is their least favourite pest.

Weed of the Week: kochia

Kochia is one of the Prairies’ more damaging weeds.

Responsible glyphosate use a priority

The editorial that appeared in May 7 edition of The Western Producer made an important point about the value of glyphosate.

Sprayer cleanup not to be ignored

A spray day doesn’t end when the farmer parks the rig. Producers who use Group 2 products that are formulated as a dry fine ground powder have one more important task when they park the sprayer: cleanup. The issue is compounded if they mix Group 2 dry products with other products that have an oily[...]

Weed of the Week: cleavers

Cleavers are something many producers would like to chop from their fields. The twisting and ropy vine-like weeds tangle through the crop, using up nutrients, water and farmers’ patience at harvest time. Galium aparine and Galium spurium, also known as false cleavers, are designated noxious under the Weed Control Act. False cleavers have a notch[...]

Agency needs to take scientific approach in making evaluations

Farmers could have been forgiven if they wondered recently, “what next?” after hearing that a United Nations panel had declared glyphosate “probably carcinogenic.”
Well, now they know.

That is a 130 percent increase in herbicide sales over[...]
