General Instructions for Genfarm Tango 480 Selective Herbicide

Incorporation:

• In most areas, the product must be incorporated into the soil within 4 hours of application.
• In Western Australia, where minimum tillage sowing equipment is used, application may occur up to 24 hours prior to sowing.

Incorporation Table:

1. Prior to furrowing out: 2 workings with Offset or Tandem disc harrows.
2. After furrowing out: 2 workings with Go-Devil discs or URis ton cultivators set at 10 cm depth.
3. Rotary Hoe: 1 working at 5-7.5 cm depth. For Sugar Cane: 7.5-13 cm depth.
4. Offset or Tandem Disc Harrows: 2 workings at an angle at 7.5-15 cm depth and 6.5-10 km per hour.
5. Heavy Diamond or Stump Jump Harrows: Weighted 20-30 kg per section at 10-13 km/hr, followed by cross work with offset or tandem disc harrows set at 7.3-15 cm depth and speed of 6.5-10 km per hour.
6. Weighted Heavy Diamond or Stump Jump Harrows: Weighted with 20-30 kg per section at 10-13 km/hr, followed by cross work with a combine at 5-7.5 cm depth and a speed of 10-13 km per hour.
7. Disc Ratoon Cultivator: 2 workings needed with discs and cultivator set at 7.5-13 cm depth.
8. Offset or Tandem Disc Harrows: Set at 7.5-15 cm depth. A second discing is required working in the opposite direction with discs set to throw treated soil into tree or vine rows.
9. Rotary Hoe: 1 working needed at 5-10 cm depth.
10. Offset Discs (Bumpers): 2 workings needed at depth 7.5-13 cm.
11. Incorporation by sowing (IBS) on a suitably prepared seedbed with heavy diamond harrows trailing or as a separate operation.
12. Post-sowing/Pre-emergence: Use heavy diamond harrows cross working at right angles to the direction of sowing. Do not attempt this method of incorporation on poorly prepared, clumpy, or cloddy soils.
13. Incorporation by sowing (IBS) with knife or blade points. Use press wheels to avoid dragging treated soil back into the seed furrow. Maintain slow to moderate speed to ensure that soil throw is not into adjacent furrows. Note: knife or blade point systems can result in poor weed control in the seed furrow as chemical displacement from this zone occurs. Stubble coverage above 40-50% ground cover can reduce weed control below acceptable levels. A knife or blade point is 12 mm or less, has no wings, inverted T, or blade, and is generally placed on a minimum 8-inch tyne spacing.

Mixing:

• Genfarm Tango 480 Selective Herbicide is an emulsifiable concentrate that mixes readily with water.
• Add the recommended amount to the spray tank during the filling operation and apply 70-450L of water per hectare (Broadacre basis) depending on soil type and stubble coverage level.
• For minimum stubble tillage retention seeding systems, the use of higher water volumes may help reduce the impact of stubble.
• Ensure adequate agitation is continued throughout the application.

Conditions for Best Results:

• Thoroughly incorporate the product as recommended.
• Soil should be well-worked and free of weeds at the time of application.
• Product effectiveness may be reduced by inadequate incorporation, high organic matter, excess clods, crop or trash residues, stones, or other foreign matter.
• Trifluralin is volatile and disappears from exposed surfaces, especially in high temperatures, winds, or warm moist soil.

Integrated Weed Management:

• Use Integrated Weed Management techniques in conjunction with Genfarm Tango 480 Selective Herbicide.
• Agronomic practices that reduce the weed seed bank in the soil prior to using Genfarm Tango 480 will result in higher weed control levels.
• Failure to use such practices may result in higher weed seed populations, requiring additional herbicide treatments.

Resistance Warning:

• Genfarm Tango 480 Selective Herbicide is a Group D herbicide.
• Some naturally occurring weed biotypes may be resistant to this product and other Group D herbicides.
• The occurrence of resistant weeds is difficult to detect prior to use, and Genfarm Crop Protection Pty Ltd accepts no liability for losses resulting from the failure of this product to control resistant weeds.

Wild Oats Control:

• Germinating wild oats lying on the soil surface will not be controlled.
• Specific wild oat control is possible with shallow cultivation.
• Poor control may occur on self-mulching soils and all soil types where deep cultivation is practiced.

Compatibility:

• Genfarm Tango 480 Selective Herbicide may be mixed with various herbicides, insecticides, and other products. Consult the compatibility section for detailed information.
• Conduct a small-scale compatibility test before mixing in the spray tank.

Equipment Maintenance and Usage:

• Keep the spray unit for herbicides only if possible. If not, thoroughly rinse tanks, pumps, lines, and nozzles with clean water following application.
• Spraymate Tank and Equipment Cleaner is suitable for removing trifluralin stains.

Protection Measures:

• Avoid application in high winds.
• Do not exceed specified rates to avoid crop damage.
• Specific planting restrictions exist for sensitive grasses, oilseed poppies, orchards, and vineyards.
• Follow drift warnings to prevent spray drift onto nearby susceptible plants.

Protection of Wildlife, Fish, Crustaceans, and Environment:

• Do not contaminate streams, rivers, or waterways with chemicals or used containers.
