With product availability issues – notably glyphosate – there could be issues with our tank-mixes for rice. Any herbicide being aerially applied with clomazone must have a specific state registration to allow the tank-mix. The full spreadsheet containing all approved mixes with clomazone products can be found on the Arkansas Dept. of Agriculture (ADA) website here.
Ultimately, as you purchase and secure glyphosate, keep in mind what you have and when you’ll use it. Some glyphosate products may not be approved for clomazone tank-mixes and might be best used in earlier burndown applications or saved for use in other cropping systems. Glyphosate products approved for tank-mix with clomazone should be reserved for at planting applications on our rice acres.
The table below provides the approved glyphosate + clomazone tank-mix options based on those provided in the file from the ADA. While we have done our best to capture the information in the below table, the ADA file and product labels should be checked to confirm accuracy.
