Recyclable Containers
Do not reuse this container for any purpose. This is a recyclable container, and is to be disposed of at a container collection site. Contact your local distributor/dealer or municipality for the location of the nearest collection site. Before taking the container to the collection site:
1. Triple- or pressure-rinse the empty container. Add the rinsings to the spray mixture in the tank.
2. Make the empty, rinsed container unsuitable for further use.
If there is no container collection site in your area, dispose of the container in accordance with provincial requirements.

OPTILL will provide control of most annual grass and broadleaf weeds in soybeans.
OPTILL is applied in tank-mix combination with glyphosate as an early preplant or preemergent application in reduced or no-till soybeans followed by a planned in-crop application of a registered herbicide. MERGE Adjuvant is required for optimum burndown activity.
OPTILL combines the two active ingredients: saflufenacil, a potent inhibitor of protoporphyrinogen-oxidase (PPO) belonging to herbicide mode of action Group 14, and imazethapyr, an inhibitor of acetocholactate synthase (ALS) belonging to the herbicide mode of action Group 2. Saflufenacil is rapidly absorbed by roots and foliage with limited systemic activity. Under active growing conditions, susceptible emerged weeds usually develop chlorotic and necrotic injury symptoms within hours and die within a few days. Susceptible germinating weed seeds will usually die as they reach the soil surface or shortly after emergence. Imazethapyr is an inhibitor of acetocholactate synthase (ALS) or also called acetohydroxyacid synthase (AHAS), a key enzyme in the biosynthesis of essential branched-chain amino acids. Plant death results from events occurring in response to ALS inhibition and low branched-chain amino acid production.

OPTILL at a rate of 147 g/ha is applied in tank-mix combination with glyphosate and MERGE Adjuvant as an early preplant or pre-emergent application in reduced or no-till soybeans. This treatment is recommended when there is a planned in-crop application of another registered herbicide.
OPTILL is compatible with all liquid glyphosate formulations registered for use as a pre-plant treatment prior to soybeans in which glyphosate is present as an isopropylamine salt, diammonium salt or potassium salt, as a tank mix-partner. Refer to the glyhosate label for rates and weeds controlled in addition to those listed below. Apply to weeds less than 15 cm in height, according to the glyphosate label. Refer to the glyphosate label for further recommendations, precautions and restrictions.

1. When applying OPTILL, always start with a clean sprayer. Thoroughly clean the sprayer by flushing the system with water containing detergent. Refer to previously applied product labels for specific cleaning instructions.
2. Fill clean spray tank one-half full of clean water and start agitation system.
3. Using a calibrated measuring device, add the correct amount of OPTILL and continue to agitate.
4. Add the correct amount of glyphosate while continuing agitation.
5. If recommended, add the correct amount of MERGE Adjuvant to the tank last.
6. Continue agitation while filling the spray tank with the remaining amount of water.
7. Continue to agitate or run the by-pass system.
8. After any break in spraying operation, agitate thoroughly before spraying again. Check inside the tank to ensure that sprayer agitation is sufficient to remix the spray materials. Do not allow the mixture to sit over night.
9. If an oil film starts to build up in the tank, drain it and clean the tank with strong detergent solution.
10. Immediately after use, thoroughly clean the sprayer by flushing the system with clean water containing detergent.
Dispose of all rinsings in accordance with provincial regulations.

The crops listed below can be grown after an application of OPTILL.
Plant Back Crops
In case of crop failure, the following crops can be planted in the same season (1)
Wheat (winter) (2)
Rotational Crops
The following crops can be planted anytime in the following season. Conduct a field bioassay (a test strip grown to maturity) the year BEFORE growing any other crop.
Barley (spring)
Corn (field)
Dry beans
Wheat (spring, winter) (2)
(1) A second application of OPTILL cannot be made in the rescue crop.
(2) Winter wheat may be re-planted in cases of crop failure or as a rotational crop 100 days following an OPTILL application. Soil preparation for re-planting should be no deeper than 10 cm.
