TREFLAN HERBICIDE: GENERAL INSTRUCTIONS

Incorporation Requirements:

• Must be incorporated into the soil within 4 hours of application.
• Applicable when the crop is sown with minimum tillage equipment (fitted with knife points or blades less than 12 mm wide, usually with press wheels).
• Incorporation may occur up to 24 hours before sowing.

Incorporation Table (Methods):

1. Prior to furrowing out: 2 workings at an angle using Offset or Tandem disc harrows.
2. After furrowing out: 2 workings using Go-Devil discs or Lilliston 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: (preferably with spiked harrows) 2 workings at 7.5 - 15 cm depth at 6.5 - 10 km/h.
5. Heavy Diamond or Stump Jump Harrow: (weighted 20 - 30 kg per section) at 10 - 13 km/h. Cross work with offset or tandem disc harrows set at 7.5 - 15 cm depth at 6.5 - 10 km/h.
6. Weighted Heavy Diamond or Stump Jump Harrow: (weighted 20 - 30 kg per section) at 10 - 13 km/h. Cross work with combine at 5 - 7.5 cm depth at 10 - 13 km/h.
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 opposite direction with discs set to throw treated soil into tree or vine row.
9. Rotary Hoe: 1 working needed at 5 - 10 cm depth.
10. Offset Discs (Bumpers): 2 workings needed at depth of 7.5 - 13 cm.
11. Incorporation by sowing (IBS): on a suitably prepared seed bed 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 (not on poorly prepared, clumpy, or cloddy soils).
13. IBS with knife or blade points: Use press wheels to avoid dragging treated soil back into the seed furrow. Maintain a slow to moderate speed.

Mixing:

• An emulsifiable concentrate that mixes readily with water.
• Add the recommended amount during the filling operation.
• Apply 70-450 L of water per hectare (broadcast basis) depending on soil type.
• Use properly calibrated low-pressure boom-type sprayer with fan tips.
• Adequate agitation is crucial. Do not leave the spray mixture without agitation for long periods.

Conditions for Best Results:

• Thorough incorporation is essential.
• 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, clods, crop or trash residues, stones, or foreign matter.
• TREFLAN is volatile and disappears from exposed surfaces, especially in high temperatures, winds, or warm moist soil.

Integrated Weed Management (IWM):

• Recommended to use IWM techniques in conjunction with TREFLAN.
• Agronomic practices that reduce the weed seed bank before TREFLAN use result in higher weed control levels.
• Failure to use such practices may result in higher weed seed populations.

Wild Oats:

• Germinating wild oat seeds on the soil surface will be controlled.
• Specific oat control is possible with shallow cultivation.
• Poor control on self-mulching soils and deep cultivation.

Compatibility:

• Compatible with various herbicides and insecticides. Detailed list provided.
• Test mixtures on a small scale before large-scale mixing.

Equipment Maintenance and Usage:

• Ideally, keep the spray unit for herbicides only.
• Thoroughly rinse tanks, pumps, lines, and nozzles with clean water following application.
• An equipment cleaning product like Spraymate Tank & Equipment Cleaner is suitable for removing TREFLAN stains.
