A water dispersible granule formulation for the post-emergence and salvage control of certain broadleaf weeds in winter cereals (including those undersown with clover, lucerne, or medics); clover, fenugreek, lathyrus, lucerne, medic, serradella, and vetch (Popany only) seed crops and pastures; chickpeas, field peas, lentils, maize, peanuts; and for the pre-emergence control of certain broadleaf weeds in maize, pigeon peas and soybeans as specified in the Directions for Use.

DIRECTIONS FOR USE
RESTRAINTS
DO NOT apply to plants which may be stressed (not actively growing) due to prolonged periods of extreme temperature (less than 5oC or greater than 30oC), moisture stress (water-logged or drought affected), poor nutrition or previous herbicide treatment as reduced levels of control may result.
DO NOT apply post-emergence treatments if rain is likely within 4 hours.
DO NOT irrigate (any method) treated crop or pasture for 48 hours after application.
DO NOT apply to crops affected by disease or by previous herbicide treatment (eg triazines or sulfonylureas).

TABLE 1A.

CHICKPEAS
Growth stages: 4 - 6 branches (no later than 6 weeks after emergence)
Crop tolerance: Trident Herbicide usually causes some transient crop yellowing and can cause reddish discolouration and height suppression. Flowering may be delayed resulting in yield suppression.
Spray additives / tank mixes: DO NOT use any spray additives, or tank mix any other chemicals with Trident Herbicide when using on chickpeas and field peas.

FIELD PEAS
Growth stages: 2 to 6 nodes (no later than 6 weeks after emergence)
Crop tolerance: Trident may cause transient crop yellowing and height suppression. On light soils in dry seasons flowering may be delayed resulting in yield suppression.
Spray additives / tank mixes: DO NOT use any spray additives, or tank mix any other chemicals with Trident Herbicide when using on chickpeas and field peas.

LENTILS
Growth stages: 4-8 fully expanded leaves DO NOT apply later than 6 weeks after crop emergence.
Crop tolerance: Trident may cause transient height reduction, crop discolouration and delayed flowering, although yields are normally unaffected. However, stress conditions after application (eg. frost, drought, nutrient deficiency, disease) may lengthen the time needed for lentils to recover. In seasons where a dry spring occurs, yields may be suppressed. Tank mixes with other products may result in growth suppression and delayed flowering which can result in yield suppression.
Spray additives / tank mixes: Uptake* Spraying Oil at 500 mL/100 L or Wetspray® 1000 at 200 mL/100 L may be applied with Trident to lentils.

FANUGREEK, LATHYRUS, VETCH (Popany only)
Growth stages: 3 fully expanded leaves onwards
Spray additives / tank mixes: Use Trident or Trident plus a wetter only. Tank mixtures with other herbicides are not recommended.

Weed: Wild Radish, Turnip Weed, Paterson’s Curse
Weed growth stage: Early flowering of the youngest weeds to early pod formation of the oldest weeds.
Rate g / ha: 25 or 50 + Uptake or wetter Use 50 g/ha only in established grazing lucerne and legume/grass pastures
Critical comments: Use Uptake Spraying Oil at 500 mL/100 L or wetting agent such as Wetspray® 1000 at 200 mL/100 L. For prevention of Wild Radish and Turnip Weed seed set, apply in a minimum spray volume of 100 L/ha from the ground or 50 L/ha from aircraft. Some re-growth may occur when wet conditions prevail after treatment.
Do not use this technique if you have already applied a Group B herbicide to the crop or pasture this season.
Only use this salvage technique with Trident once per cropping cycle to minimise the development of herbicide resistance. If you suspect herbicide resistance in broadleaved weeds do not use this technique.
DO NOT use a Trident salvage spray in pastures for seed production.
WARNING: Weeds that have not started to flower at application time may not be controlled by the salvage spray technique. For Wild Radish, time treatment to coincide with green, soft pods prior to embryo maturation in seeds.
Squeeze pod between finger nails to see if any green/ white seeds are present. Best time to treat is before seeds are visible.
Use 50 g/ha in established lucerne and legume/grass pastures.

MINIMUM RECROPPING PERIODS:
Trident is broken down in the soil by microbial activity. Warm, moist soil conditions favour highest microbial activity and quickest residue breakdown. For the recropping periods NNSW & Qld refers to summer dominant rainfall areas, where crops are grown on deep black earth soils (vertosols), with no impermeable sub-horizon in the top 30 cm. SNSW, Vic, Tas, SA and WA refers to winter dominant rainfall areas on soils with no impermeable sub-horizon in the top 30cm. Also see the comments on rainfall and soil type below.

Rainfall – is required to maintain soil wetness for at least one week over the warm months to enable microbial degradation of herbicide residues to allow safe planting of sensitive crops.
For SNSW, Victoria, Tasmania, SA and WA a minimum of 25mm and preferably 50mm or more rain must have fallen over the warm months of the year. For NNSW and Qld a minimum of 50mm and preferably 100mm rain or more must have fallen over the warm months of the year.
Soil type – on shallow, duplex, low organic matter soils with an impermeable sub-horizon within the root zone (30cm deep or less) and alkaline surface soil, sensitive crops should NOT be planted until 2 years after application of TRIDENT at etiher 25 or 50 g/ha.
(For crops grown in NNSW and Qld on soils other than vertosols, call Adama or your local reseller for more advice.)

GENERAL INSTRUCTIONS
Trident™ granules in water soluble bags readily disperse in water and will do so once added to fast moving water. Maintain agitation at all times, including during mixing as well as spraying. Only mix sufficient spray solution for immediate use and avoid storing.

MIXING
Spray rigs with premix hoppers
For spray rigs that have a drop down chemical induction hopper, three-quarter fill this hopper with water and have the rinsing sprinkler operating. Add the Trident water soluble bags and when they are dissolved and the granules are dispersed, transfer this batch into the quarter filled main tank. Continue to rinse the hopper until the entire product has washed through.
Spray rigs with limited bypass agitation
When Trident is added to the spray tank in water soluble bags, for spray rigs that have limited bypass agitation, then as for most granulated formulations, re-disperse the Trident in a bucket before adding them to the main tank. Add Trident while stirring until the granules have dispersed.
Tank mixes – this order should be followed:
1. Quarter fill the spray tank and agitate.
2. Add Trident using the mixing procedure above.
3. Add Firepower® if to be used.
4. Half fill the spray tank.
5. Add wettable powders, dry flowables, suspension concentrates, soluble liquids and/or emulsifiable concentrates.
6. Add Uptake Spraying Oil when half full.
7. Other adjuvants add according to their label.
8. Add water to fill the spray tank.

APPLICATION
- Ground Application: Apply Trident in 50 to 150 litres of water per hectare through a calibrated sprayer that delivers at least medium quality spray as defined by the ASABE S572.
- DO NOT apply Trident under conditions likely to cause drift onto waterways, susceptible crops or land to be planted with susceptible crops. Unsuitable conditions are dead calm, excessive wind and/or small droplets.
- Best results are achieved where applications are made on warm (greater than 5oC), sunny days applying more than 50 L/ha of total spray volume (preferably more than 75 L/ha) and where spray coverage is maximised.

COMPATIBILITY
- Always allow 7 days between application of a grass herbicide and Trident in chickpeas and field peas.
- In lentils, adjuvant, broadleaf or grass herbicide, insecticide and foliar fertiliser tank mixes may result in transient height reduction, crop discolouration and delayed flowering, although yields are normally unaffected. However, stress conditions after application (eg. frost, drought) may lengthen the time needed for lentils to recover and in years where a dry spring occurs, yields may be suppressed.
- Trident is compatible with the following:
Adjuvants: Uptake* Spraying Oil, Hasten* Spray Adjuvant, Wetspray 1000.
Broadleaf herbicides: Farmozine, Broadstar, Bronco 200 (bromoxynil), 2,4-DB, Bonanza Elite (lentils and field peas only), Diuron (liquid or wettable granule), Colt, Victory 750 SG, Victory, MCPA amine, MCPA ester, MCPA sodium salt, Lynx WG, Vezir, Flagship 200, Pendimethex, Terbutrex, Enforcer 242, Trilogy
Grass weed herbicides: Platinum (lentils only), Mandate, Rhino 500 (ryegrass only), Spraytop 250 SL, Simanex 900 WG, Trilogy, Tristar* Advance Selective Herbicide, Victory, Wildcat* Selective Herbicide (wild oats only)
Insecticides: Dimethoate, esfenvalerate (lentils only), Strike-Out, omethoate.
Fungicides (lentils only): Howzat SC, Cavalry 720 SC, Farmoz Mancozeb 750 DF .
Foliar Fertilisers: Broadacre zinc (lentils only).

CLEANING SPRAY EQUIPMENT
After using Trident, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose. Drain the tank and clean any filters in the tank, pump, lines and nozzles.
- To rinse. After cleaning the tank as above, quarter fill the tank with clean water and circulate through the pump, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.
- To decontaminate. Before spraying sensitive crops (which include canola, cotton, faba beans, lupins, sorghum and sunflowers), wash the tank and rinse the system as above. Quarter fill the tank and add an alkali detergent (e.g. SURF*, Cold Water SURF Concentrate*, Dynamo Matic Concentrate*, OMO* or DRIVE* at 500 mL/100 L of water or the powder equivalent at 500 g/100 L) and circulate throughout the system for at least fifteen minutes. Drain the whole system. Remove filters and nozzles and clean them separately. Finally flush the system with clean water and allow to drain. Chlorine based cleaners are not recommended. Nufarm Tank and Equipment Cleaner* is not recommended.
Rinse water should be discharged onto a designated disposal area or, if this is unavailable, onto unused land away from desirable plants and watercourses.

RESISTANT WEEDS WARNING
Farmoz Trident™ Herbicide is a broadleaf herbicide with no annual ryegrass activity and is a member of the triazolopyrimidine sulfonanilide (sulfonamide) 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, Adama Australia Pty. Ltd. 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, local Department of Agriculture, or local Adama representative.
