Commenza^™

Herbicide

group

Commenza™ herbicide provides three active ingredients and residual activity for soil applied cross-spectrum broadleaf and grass control in soybeans. Multi-mode of action technology ensures robust performance against resistant and hard to control weeds.

Benefits

Soil-applied weed control solution

Commenza is a pro-active broadspectrum herbicide program to establish excellent control of most major annual weeds in soybeans. With 3 modes of action, Commenza delivers robust control of the important weeds such as foxtails, nightshade, lamb's-quarters, ragweed, nutsedge and many others in conventional, conservation tillage or no-till soybean production systems.

Multi-mode of action

With three proven active ingredients, Commenza delivers overlapping effective modes of action on key weeds such as Eastern black nightshade.

Convenience and confidence

Convenient 20 acre co-pack is easy to handle and measure. And a complete herbicide program from one manufacturer provides you confidence and assurance of performance.

Packaging
Case:
- Broadstrike RC: 715 g bottle
- Metribuzin Mx 75 DF: 4.5 kg jug

Crop Rotation
- 4 months: winter wheat
- 10 months: spring wheat, spring barley, oats, soybeans, common beans (dry, snap), lima beans, processing peas, field corn and seed corn
- Following an application of Commenza in a dry year, the risk of injury to rotational crops may increase in light-textured soils containing less than 2% organic matter due to a higher bioavailability of herbicide residues for plant uptake.
Rotational crop restrictions: When tank mixing with other herbicides, follow the most restrictive crop rotation guidelines on the label of each product used.

Rotational crops, except field corn and soybeans, may sustain herbicide injury if dry conditions, not favourable to herbicide breakdown, persist following application of Commenza.

A field bioassay should be conducted before planting other crops not listed above.

A successful bioassay means growing test strips of the crop(s) to maturity intended for production the following year.
