Growers of 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 it says will give growers residual control of several broad-leaf weeds and enhanced post-emergence weed control when tank-mixed with glyphosate.
Valent worked on the registration with Engage Agro, a Guelph firm specializing in registering and marketing crop pesticides for niche markets.
Chateau is registered to control annual nightshade species, 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 Group 2-or Group 5-resistant weeds.
