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

Technical Specifications

Application Method

Apply Commenza in conventional, conservation tillage or no-till soybean production systems.

Soybeans: Do not apply to areas where the soil pH is greater than 7.8 and organic matter is less than 2% (both apply) as this may result in decreased crop tolerance.

Soybean Application Methods: Surface pre-plant, pre-emergence, pre-plant incorporated

Rainfast: 2 hours
Rates
- 35 g/ac + 225 g/ac +525 ml/ac
Acres Treated: 20 acres/case

Water Volume: 10-20 US gal/ac
Packaging
Case:
- Broadstrike RC: 715 g bottle
- Metribuzin Mx 75 DF: 4.5 kg jug
- S-Metolachlor 960: 10.5 L 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.
