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
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.

Additional Information
The pre-harvest interval for Commenza is 90 days.
