Pyro Herbicide is designed for use as a contact herbicide for broadleaf weed control.  Pyro Herbicide will damage emerged crop plants.  Apply Pyro Herbicide prior to the emergence of the crop, either as a pre‐seeding or post‐seeding application.  Only weeds that have emerged at the time of application will be controlled.  Apply when weeds are in the seedling stage and actively growing. Pyro Herbicide, a member of the phenyl pyrazole class of herbicides, inhibits the protoporphyrinogen oxidase (PPO) enzyme which results in cell membrane destruction and necrosis. Pyro Herbicide is rainfast within one hour after application.   Warm, moist growing conditions promote active weed growth and enhance the activity of Pyro Herbicide by allowing maximum foliar uptake and contact activity.  Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and regrowth may occur.

For best results, ensure thorough spray coverage of target weeds.  Refer to the specific use directions sections of this label for complete use details. As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests. 
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.
DO NOT apply by air.
Buffer zones: Use of the following spray methods or equipment DO NOT require a buffer zone: hand‐held or backpack sprayer and spot treatment and soil incorporation. The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrub lands) and sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands).  
For tank mixes, consult the labels of the tank‐mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture and apply using the coarsest spray (ASAE) category indicated on the labels for those tank mix partners. The buffer zones for this product can be modified based on weather conditions and spray equipment configuration by accessing the Buffer Zone Calculator on the Pest Management Regulatory Agency web site.

Pyro Herbicide can be applied pre‐seeding or post‐seeding prior to crop emergence, in the crops from the crop groups listed below as well as canary seed. Crops not listed can be planted one month after Pyro Herbicide application.

Crop Group 6: Legume Vegetable (succulent or dried)
Broad bean (fava bean), chickpea, lentil, soybean, pea (Pisum spp. includes dwarf pea, edible‐pod pea, English pea, field pea, garden pea, green pea, snow pea, sugar snap pea) and bean (Lupinus spp. includes grain lupin, sweet lupin, white lupin, and white sweet lupin; Phaseolus spp. includes field bean, kidney bean, lima bean (dry), navy bean, pinto bean, runner bean, snap bean, tepary bean, wax bean; Vigna spp. includes adzuki bean, asparagus bean, blackeyed pea, catjang, Chinese longbean, cowpea, Crowder pea, moth bean, mung bean, rice bean, southern pea, urd bean, yardlong bean)

Crop Group 15: Cereal Grains
Barley, buckwheat, corn (sweet and field), pearl millet, proso millet, oats, popcorn, rye (spring and fall), triticale and wheat (spring, durum, winter)

Crop Group 20A: Oilseeds, Rapeseed Subgroup  
Canola (rapeseed) and mustard seed

1. Select a spray volume and nozzle type that will ensure thorough coverage and uniform spray pattern. Use a minimum of 100 L spray volume per hectare.    
2. Fill the spray tank 1/3 full with fresh water and start agitation.
3. If tankmixing with glyphosate, add the required amount of glyphosate to the tank first, agitate well. Always consult the label of the tank mix partner(s) for minimum spray volume requirements and apply the tank mixture using a water volume recommended for all products.
4. Add the required amount of Pyro Herbicide to the tank, agitate well.
5. Continue to fill tank and maintain agitation for at least 5 minutes to ensure thorough mixing.
6. Use the spray preparation of Pyro Herbicide within 24 hours. Product degradation may occur under alkaline conditions (pH >7.5). If spray solution is left standing without agitation, thoroughly agitate before resuming the spraying operation.

Apply the spray mixture uniformly with properly calibrated ground equipment only.  Ensure thorough coverage and a uniform spray pattern.  Flat fan nozzles are recommended (minimum 100 L spray volume per hectare).  Use 50 mesh filter screens or larger (metal or nylon).  A spray pressure of 210 ‐ 275 kPa is recommended.  Apply uniformly.

Pyro Herbicide ALONE 
Rate: Apply 180 ‐ 360 mL of Pyro Herbicide per hectare tank mixed with a non‐ionic surfactant blend, such as Nufarm Enhance, NUP‐09025 Adjuvant, Ag‐Surf or Merge, at 0.25% v/v (i.e. 2.5 L in a total of 1000 L spray volume).
180 mL/ha of Pyro Herbicide controls smaller populations of weed seedlings at up to the 3‐leaf stage. Use up to 360 mL/ha Pyro Herbicide for more consistent control of susceptible weeds, to control higher weed populations and on weed seedlings up to the 4‐leaf stage or if growing conditions are less than ideal.
Timing: For best results apply to emerged, young, actively growing weeds that are less than 5 cm tall or across.  Thorough coverage of target weeds is essential.

To avoid subsequent injury to crops, immediately after spraying and prior to spraying other crops, thoroughly remove all traces of Pyro Herbicide from mixing and spray equipment as follows:
Drain tank; then flush tank, boom and hoses with clean water for a minimum of ten minutes.
Next, prepare a sprayer cleaning solution by adding 3 litres of ammonia (containing at least 3% active) per 100 litres of clean water. Prepare sufficient cleaning solution to allow the operation of the spray system for a minimum of 15 minutes to thoroughly flush the tank, hoses, spray boom and spray nozzles.
If possible, leave the ammonia solution or fresh water left in the spray tank, hoses, spray booms and spray nozzles overnight or during storage to dissolve and dilute any remaining traces of herbicide.
Nozzles and screens may be cleaned separately in a bucket containing cleaning agent and water.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

For resistance management, Pyro Herbicide is a Group 14 herbicide.  Any weed population may contain or develop plants naturally resistant to Pyro Herbicide and other Group 14 herbicides.   The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field.  Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist.  Appropriate resistance‐management strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of Pyro Herbicide or other Group 14 herbicides with different herbicide groups that control the same weeds in a field.  
Use tank mixtures with herbicides from a different group when such use is permitted. To delay resistance, the less resistance‐prone partner should control the target weed(s) as effectively as the more resistance‐prone partner.
Herbicide use should be based on an integrated weed management program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical control methods), cultural (for example, higher crop seeding rates; precision fertilizer application method and timing to favour the crop and not the weeds), biological (weed‐competitive crops or varieties) and other management practices.
Monitor weed populations after herbicide application for signs of resistance development (for example, only one weed species on the herbicide label not controlled). If resistance is suspected, prevent weed seed production in the affected area if possible by an alternative herbicide from a different group. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.
Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance‐management and/or integrated weed‐management recommendations for specific crops and weed biotypes.
