GENERAL INSTRUCTIONS
MIXING
STINGER Herbicide is a water dispersible granule to be mixed with water. STINGER should be added to the spray tank with simultaneous agitation. If ability to agitate the spray tank is limited, premix the STINGER in a bucket before adding to the main tank. Once diluted correctly, STINGER Herbicide remains dispersed. THE MATERIAL MUST BE KEPT IN SUSPENSION AT ALL TIMES BY CONTINUOUS AGITATION.
When prepared spray solution has been allowed to stand, thoroughly re-agitate before using. In tankmixes STINGER must be in suspension before adding the partner product or surfactant.
If tank mixing with other products, the following order should be followed:
1. Quarter fill the spray tank, maintaining agitation, then:
2. Add STINGER Herbicide (as described above).
3. Add water to half fill the spray tank.
4. Add wettable powders, water dispersible granules or suspension concentrates.
5. Add emulsifiable concentrates.
6. Add the surfactant when spray tank is half full.
7. Add water to bring to the final spray volume.

COMPATIBILITY
STINGER Herbicide is compatible with the following:
Broadleaf Herbicides: Bromoxynil, bromoxynil-MCPA, Hotshot™, Lontrel™ Advanced, Lontrel™ 750 SG, Dow AgroSciences LVE 600 MCPA, Canvas™ 750, Starane™ Advanced, Tordon™ 242, Tordon™ 75-D, Statesman™ 720 and gylphosate.
Insecticides: Lorsban™ 500 EC and omethoate (e.g. Lemat®). Some increased temporary crop yellowing may occur when STINGER Herbicide is applied as a tank mix with these insecticides.

USE OF SURFACTANT/WETTING AGENT
Only BS1000 Biodegradable surfactant, Chemwet 1000 Wetting Agent, Uptake Spraying Oil or Pulse Penetrant are recommended for use with STINGER. Not all surfactants or crop oils are of equal quality. Dow AgroSciences does not support the use of products other than those listed above.
Instructions specific for woody and herbaceous weed control
- If a specific surfactant/wetting agent is not listed in the DIRECTIONS FOR USE table, or when mixing with glyphosate use BS1000 or Chemwet 1000 at 100 mL/100 L of final spray solution (0.1 % v/v).
- When Pulse Penetrant is recommended in the DIRECTIONS FOR USE table, use 20 mL/10 L (gas gun application) or; 100 or 200 mL/100 L (boom or high volume applications) (i.e. 0.1 or 0.2% v/v)
- When Uptake Spraying Oil is recommended in the DIRECTIONS FOR USE table, use 500 mL/100 L of final spray solution (i.e. 0.5 % v/v).
Instructions specific for treatment of pasture and pasture renovation
- Always add BS1000 or Chemwet 1000 at 200 mL/100 L of final spray solution (0.2 % v/v).

APPLICATION
1. Cropping and Fallow Situations
Ground Boom Spraying
Apply in 50-100 L water/ha using a coarse spray through accurately calibrated equipment. Avoid overlapping and shut off spray booms while starting, turning, slowing or stopping as injury to the crop may occur.
Aerial Application
Apply in not less than 30 L water/ha using a coarse spray through accurately calibrated equipment.
2. Pasture and Non-cropping Situations
High Volume Handgun application
Spray foliage stems and canes until wet. Ensure coverage is uniform and complete. Use pressures of 550‑1500 kPa depending on target species and size of bush. Use larger nozzles and higher pressures for larger bushes. Indicative spray volumes are 3000 L/ha for large woody weeds and 1-2 m high blackberry; and 500‑1000 L/ha for small herbaceous weeds such as ragwort.
Gas Gun Application
Apply 50 mL shots to 4-5 m2 of surface area of the weed to ensure good coverage of all foliage is achieved. This relates to 20 droplets/cm2 of leaf surface. The use of a suitable marker dye is recommended.
Ground Boom Spray Application
Apply in a minimum of 70 L prepared spray/ha using a coarse spray. Increase to 200 L/ha or more in dense stands.
Aerial Application (by helicopter only)
Apply using at least a coarse spray through accurately calibrated equipment. Apply in a minimum of 100 L/ha on blackberries or 60 L/ha on Mimosa pigra. Higher water volumes up to 200 L/ha may be necessary on Mimosa pigra to ensure adequate coverage where bushes are large and terrain is steep. Spray using the half overlap opposite pass technique.

CLEANING SPRAY EQUIPMENT
Immediately after spraying thoroughly remove all traces of STINGER Herbicide from mixing and spray equipment as follows:
- Wash down exterior of sprayer before flushing tanks, lines, etc.
- Drain tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, drain the tank and clean any tank, pump, line and nozzle filters for a minimum of 10 minutes.
Partial Cleaning (Rinse only – before using rig to spray barley, triticale and wheat):
After cleaning the tank as above, quarter fill the tank with clean water and circulate through the pump, line, hoses and nozzles. Drain and repeat procedure twice.
Complete Cleaning (Decontamination – before using rig to spray crops that are susceptible to STINGER):
- After cleaning the tank as above, fill the tank with clean water and add 300 mL household chlorine bleach (containing 4% chlorine) per 100 L of water. Household bleach should be less than 12 months old, and stored away from direct sunlight. Flush through boom and hoses then allow to stand for 15 minutes with agitation engaged, then drain.
- Drain tank, then flush tank, boom and hoses with clean water for a minimum of 10 minutes.
- Nozzles, screens, filters, relief valves, dump lines, caps and taps at the end of spray lines, tank lids, flow meters, lines to pressure gauges, external tank indicators, induction hoppers, etc should be removed/pulled apart and cleaned separately. To remove traces of chlorine bleach, rinse the tank thoroughly with clean water and flush through hoses and boom.
CAUTION: DO NOT use chlorine bleach with ammonia.
DO NOT clean equipment in an enclosed area.
Rinse water should be discharged onto a designated disposal area or, if this is unavailable, onto unused land away from desirable plants and their roots and watercourses.

RESISTANT WEEDS WARNING
STINGER Herbicide contains members of the pyridine and sulfonyl urea group of herbicides. The product has the disrupters of plant cell growth and acetolactate synthase (ALS) inhibitor modes of action. For weed resistance management, the product is a Group I + Group B herbicide. Some naturally occurring weed biotypes resistant to the product and other Group I and/or B herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by this product or other Group I or Group B herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Dow AgroSciences accepts no liability for any losses that may result from the failure of the product to control resistant weeds. Strategies to minimise the risk of herbicide resistance are available. Contact your farm chemical supplier, consultant or local Department of Agriculture.
