Fruit, veg growers get new herbicide

Growers of crops such as grapes, strawberries, highbush blueberries and assorted tree fruits as well as potatoes, onions and asparagus will get a new active ingredient for weed control.

Valent Canada has picked up registration for Chateau, a Group 14 flumioxazin herbicide which it says will give growers residual control of several broadleaf weeds and enhanced post-emergence weed control when tank-mixed with glyphosate.

Valent worked on this registration with Engage Agro, a Guelph company specializing in registration and marketing of crop pesticides for niche markets.

Chateau is registered to control annual nightshade species (Eastern black nightshade and hairy nightshade), pigweeds (redroot and green), common ragweed, common lambsquarter and dandelion, and to suppress green foxtail.

As a Group 14 (which also includes products such as Nufarm’s CleanStart), Chateau also “offers new management options for weeds resistant to
Group 2 and 5 herbicides.”

Chateau’s “rapid soil and water dissipation, along with a low use rate, results in a low carryover potential to rotational crops,” ” said Regina Rieckenberg, sales and marketing manager for Valent
Canada, in the two companies’ recent release.

“Additionally, Chateau will not leach or volatilize, which allows it to stay where it is intended to be used.”
