DIRECTIONS FOR USE: For application to triticale and wheat (excluding durum varieties) only from 3 leaf up to 1st node of the crop.
RESTRAINTS:
DO NOT apply to crops or weeds which may be stressed due to prolonged periods of extreme cold, moisture stress (water-logging or drought) or previous herbicide treatment, as crop damage or reduced levels of control may result (see crop safety warning below).
DO NOT spray if rain is likely to occur within 6 hours.
DO NOT apply later than the 1st node stage of the crops.
DO NOT apply by air.
DO NOT apply to durum varieties of wheat.
DO NOT double overlap or double spray crop.
DO NOT apply to paddocks where there is a high risk of weeds resistant to Group B herbicides.

Table 1. Grass weed control or suppression

Control
Weeds: Brome grass, (Bromus diandrus), (pre-tillering) Phalaris spp., Wild oats (Avena spp.) 
Suppression
Weeds: Annual ryegrass (Lolium rigidum), Barley grass (Hordeum leporinum), Silver grass (Vulpia spp.)

WITHHOLDING PERIODS
When using Crusader Herbicide in a tank mix with another product, observe whichever Harvest or Grazing/Stockfood Withholding Period that is the longer.
Harvest: NOT REQUIRED WHEN USED AS DIRECTED.
Grazing/Stockfood: DO NOT GRAZE OR CUT TREATED CROPS FOR STOCK FEED FOR 4 WEEKS AFTER APPLICATION.

CROP SAFETY
Yield is normally unaffected by treatment with Crusader Herbicide or tank mixes. However, transient stem shortening and crop yellowing may occur. Symptoms may be worse where the crop is stressed, heavy rain/irrigation follows application, crops are grown in alkaline soil conditions, crop has poor root growth, double overlap of spray has occurred or a combination of any or all the above. Where crop stress occurs, a longer period may be required for recovery, especially if the crop is stressed by root or foliar disease, poor nutrition, water logging, drought or cold stress. In severe cases and seasons where a hot, dry spring occurs, flowering may be delayed and yield may be reduced. Crusader Herbicide has been tested over major commercially grown crop varieties, but not all of those that may be grown. For information on crop variety selectivity consult your local reseller or Dow AgroSciences.
Note: Application of another Group B herbicide to the same crop before or after Crusader’s use may result in more injury than described above. Consult Dow AgroSciences for advice.

GENERAL INSTRUCTIONS
Crusader is a selective sulphonamide herbicide. It is a foliar herbicide for post-emergence use in wheat.
It will not reliably control weeds that emerge after treatment. Best results are achieved under good growing conditions. Treatment of crop or weeds that are stressed must be avoided.

MIXING
Crusader Herbicide is an oil-based concentrate which may show some separation on storage. Roll, shake or invert the container several times to ensure that Crusader Herbicide has completely redispersed before measuring to mix. Crusader Herbicide should be added to the spray tank with simultaneous agitation. If agitation is limited, premix the Crusader Herbicide in a bucket before adding to the main tank. Once diluted correctly, Crusader Herbicide remains in suspension.

Tankmixing
If Crusader is to be mixed with other products, use the following order:
1. Quarter fill the spray tank, maintaining agitation,
2. Add Crusader 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 wetter when spray tank is half-full,
7. Add water to bring to the final spray volume.
Crusader Herbicide should be mixed and sprayed out within 8 hours.

COMPATIBILITY
Crusader Herbicide is compatible with the following:
Broadleaf herbicides: metsulfuron (eg. Ally® Herbicide), bromoxynil, bromoxynil-MCPA, Conclude™ Herbicide, Hotshot™ Herbicide, Lontrel™ Herbicide, Lontrel 750 SG Herbicide, Dow AgroSciences LVE 600 MCPA, MCPA LVE, Starane™ Advanced Herbicide and Torpedo™ Herbicide.
Adjuvants: Always use either BS 1000 or Chemwet 1000
at 250 mL/100L spray volume.

APPLICATION
Boom Spraying: apply Crusader in sufficient water to obtain complete and even coverage. It should be
applied by an accurately calibrated ground rig using a water volume of 50–100 L/ha. Sprayers should apply a medium to coarse quality spray in accordance with
ASABE standard S-572. Where coarse spray quality is to be applied, use a minimum of 70 L/ha spray volume.

CLEANING SPRAY EQUIPMENT
After using Crusader Herbicide, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, drain the tank and clean tank, pump, line and nozzle filters.
Partial Cleaning – Rinse only before using sprayer to treat triticale or 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 sprayer to treat crops that are susceptible to Crusader Herbicide:
After cleaning the tank as above, quarter fill the tank with clean water and add a liquid alkali detergent at 500 mL/100 L water and circulate throughout the system for at least fifteen minutes. Drain the whole system. Then remove filters and nozzles and clean separately. Finally rinse inside the tank thoroughly using a pressure hose and flush system with clean water and allow to drain. Note: Chlorine-based cleaners are NOT recommended. These tank cleaning recommendations are for Crusader only. Please consult tankmix partner labels to determine requirement for decontamination for other products.
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
GROUP B HERBICIDE
Crusader Herbicide contains a member of the triazolopyrimidine sulfonanilide group of herbicides. The product has the acetolactate synthase (ALS) inhibitor mode of action. For weed resistance management, the product is a Group B herbicide.
Some naturally occurring weed biotypes resistant to the product and other Group 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 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.
Do not rely solely on Crusader or other Group B herbicides for weed control. Always use an Integrated Weed Management program with herbicides that have other modes-of-action, together with non- chemical methods of control. CropLife Australia resistance management strategies are available from local agricultural chemical suppliers or at www.croplifeaustralia.org.au. Use these strategies to limit the build up of resistant weeds on your farm.

PRECAUTION
Re-entry Period: Nil re-entry period if wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical resistant gloves. If not wearing protective clothing as described above, allow the spray to dry prior to re-entry.
Protective clothing must be laundered after each day’s use.
