DIRECTIONS FOR USE
VIPER Herbicide Tank-Mix is a selective herbicide that can be applied as an early postemergence treatment in field and succulent peas for broad-spectrum weed control. Cool weather conditions or drought will delay herbicidal activity and if prolonged, may result in poor weed control.
Use of VIPER Herbicide Tank-Mix in hot, humid weather may result in temporary leaf yellowing, leaf flecking, bronzing or burning. The crop usually outgrows this condition within 10 days.
DO NOT apply VIPER Herbicide Tank-Mix to field peas that have been subjected to stress from conditions such as hail damage, flooding, drought, hot, humid weather, widely fluctuating temperature conditions, prolonged cold weather or injury from prior herbicide applications, as crop injury may result.
Apply using ground equipment only. DO NOT APPLY BY AIR.
DO NOT apply more than once per year.
CAUTION: Do not graze the treated crops or cut for hay; sufficient data are not available to support such use.
Pre-harvest Interval: Field peas can be harvested 60 days after treatment. Succulent peas can be harvested 40 days after treatment.
DO NOT apply VIPER Herbicide Tank-Mix when weather conditions may cause spray drift from treated areas to adjacent crops.
Lentils, adzuki and mung beans, cucumbers, sugar beets and sunflowers can be injured by VIPER Herbicide Tank-Mix.
Overspray or drift to sensitive habitats should be avoided. A buffer zone of 11 metres is required between the downwind point of direct application and the closest edge of (1) sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, pastures, rangelands, and shrublands), (2) sensitive aquatic habitats (such as lakes, rivers, sloughs, ponds, coulees, prairie potholes, creeks, marshes, streams, reservoirs, and wetlands) and (3) estuarine or marine habitats.
DO NOT apply during periods of dead calm or when winds are gusty.
DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, coulees, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands), estuaries or marine habitats.
As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

MIXING INSTRUCTIONS
1. Use 100 L/ha of water.
2. Use a 50-mesh (or coarser) filter screen.
3. Fill the spray tank with three-quarters of the required amount of clean water, start agitation and continue agitation throughout the entire mixing and spraying procedure.
4. Add the required amount of VIPER A Herbicide soluble bag(s) directly into the sprayer through the tank opening.
5. Add VIPER B Herbicide followed by recommended amount of nitrogen source (UAN 28%).
6. Agitate for at least ten minutes to dissolve the herbicide. After the herbicide is dissolved, continue agitation.
7. Complete filling the tank to the desired level with water. If agitation is stopped for more than 5 minutes, re-suspend spray solution by full agitation prior to commencing spraying again.
8. Between loads of VIPER Herbicide Tank-Mix, check in-line and nozzle screens and rinse clean if necessary.
9. Upon completion of spraying VIPER Herbicide Tank-Mix, thoroughly flush tank, boom, hoses and in-line and nozzle screens with clean water to avoid possible injury to other crops.

FOLLOW CROPPING
Winter wheat can be planted 3 months after treatment (3 MAT) as a rotational crop.
Initial crop injury to non-CLEARFIELD canola may be observed. Avoid spray overlap as yield reduction may result. The following crops may be grown safely the year following an application:
Canary seed
Field corn
Field peas
CLEARFIELD Canola (e.g., canola varieties with the CLEARFIELD trait)
Non-CLEARFIELD canola
Lentils
Spring wheat
Durum wheat
Spring barley
Sunflower
Tame oats
Flax
Chickpeas
CLEARFIELD Sunflowers (e.g., sunflower varieties with the CLEARFIELD trait)
The following crop may be grown safely two years following an application:
Mustard (condiment type only)
There are insufficient data for other follow crops. Conduct a field bioassay (a test strip grown to maturity) the year before growing any crop other than those listed above.
