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 kill weeds.
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.
With three proven active ingredients, Commenza delivers overlapping effective modes of action on key weeds such as Eastern black nightshade.
Convenient 20 acre co-pack is easy to handle and measure. And a complete herbicide program from one manufacturer provides you confidence and assurance

One case treats 20 acres

• 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
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.
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.
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.
The pre-harvest interval for Commenza is 90 days.
