Prairie wheat and durum growers this year can get one of their wild-oat herbicides suspended rather than stirred.
Syngenta Canada has picked up federal registration for a suspension-concentrate version of its Group 2 flucarbazone herbicide Sierra. The new version, branded Sierra 2.0, will be sold in liquid (397.33 grams per litre) rather than Sierra’s water-dispersible granular form.
Sierra 2.0’s label covers it for use against wild oat, green foxtail, volunteer tame oat and "certain broadleaf weeds" in fields of spring wheat — hard red spring, Canada Prairie spring, soft white spring and/or extra strong (utility) spring — and durum.

How Canada’s farmers are producing record crops despite droughts and floods
Western Canadian farmers are using minimum and zero-till farming, tile drainage, slow-release fertilizer, and better crop breeding to produce record crops despite drought conditions.
Broadleaf weeds on the Sierra 2.0 label include redroot pigweed, wild mustard, stinkweed, volunteer canola, green smartweed and shepherd’s purse.
The product can also be used against Group 1- and Group 8-resistant wild-oat biotypes and Group 1- and Group 3-resistant green foxtail biotypes, the company said.
Growers in the herbicide’s approved areas — the three Prairie provinces and B.C.’s Peace region only — will get "the added benefits of a liquid formulation and built-in safener, for an easier-to-use product," Jon Habok, Syngenta Canada’s asset lead for cereal herbicides, said in a release Wednesday.
Sierra 2.0 also has "a long list of proven tank-mix partners for broader spectrum activity," Syngenta said, noting the product must be tank-mixed with a labeled surfactant.
