Several new herbicides have been added to Manitoba Agriculture’s 2024 Guide to Field Crop Protection.
“We haven’t had a new herbicide group in over 40 years,” said Manitoba Agriculture weed specialist Kim Brown.
“However, we do have some new products that are within the existing groups.”
Two of the 11 new products are meant to help producers combat kochia.
“Blackhawk Evo is a burn-off product very similar to Blackhawk, but they’ve added dichloroprop (Group 4) to it now,” said Brown.

The product also includes 2,4-D and pyrofluid (Group 14) and is registered for wheat, barley, rye, triticale, field corn and canarygrass.
“I put ‘new tool for kochia’ in quotation marks,” said Brown.
“The dichloroprop has been shown to do well with kochia, and there is more dichloroprop in this product.”
Oxbow is another new product aiming at kochia through dichloroprop. The other active ingredient in that product is bromoxynil (Group 6).
“This looks like it’s going to be a really good broadleaf weed product,” said Brown.
Two other additions are essentially co-formulations of products that have been used in the past.
Authority Strike (Group 14, plus carfentrazone) is used for burn-off and weed control. It is basically the same as Authority Charge but has been co-formulated so that everything is in one jug. Authority Strike is registered for wheat (spring and durum), mustard, chickpeas, fababeans, field peas, flax, sunflowers and soybeans.
Intruvix II — a burnoff, plus residual weed control product — is also a co-formulation of a previous product name.
“Intruvix II is basically the same as Intruvix, which is tribenuron (Group 2), plus dicamba (Group 4), plus carfentazone (Group 14),” said Brown.
The seven other new products in the guide include Advantage Glufosinate Plus, Batalium, Callisto, OnDeck, Restore NXT, Select Plus and Varro FX.
