GENERAL INSTRUCTIONS:

Smart Pass 450 Herbicide Overview:

• Smart Pass 450 Herbicide is a water-soluble liquid with non-selective herbicidal activity against broadleaf weeds.
• It controls emerged weeds only and provides no residual control. Visible effects may take 7-21 days.
• Absorbed by plant foliage, it accumulates in growth regions, disrupting nutrient synthesis and causing yellowing, wilting, browning, and deterioration of above-ground growth.

Application Timing:

• Apply to emerged weeds under favorable conditions.
• Do not treat weeds under poor growing or dormant conditions (drought, waterlogging, disease, insect damage, frost, heavily covered with dust or silt).
• Rainfall within 6 hours of application may reduce effectiveness.
• Do not spray in strong winds.

Crop Establishment:

• Recommended as a herbicide additive to glyphosate for controlling emerged weeds before crop establishment.
• Observe Plant Back Periods to ensure safe sowing.
• Factors affecting the degradation process include moisture, temperature, and soil characteristics.
• Conditions that may delay crop germination include heavy green or decaying weed growth, soil compaction, cold and wet soils, deep seeding, and prior use of residual herbicides.
• Recommended practices to minimize effects include reducing weed bulk, producing a friable seedbed, avoiding certain pre-emergent herbicides, and using the correct seeding depth.

Application Equipment:

Boom Equipment:

• Recommended spray volumes: 25-100L/ha, with higher volumes for specific herbicides.
• Flat fan nozzle equipment using pressures in the range of 240-280kPa.
• Boom height set to ensure double overlap of nozzle patterns at the top of the weed canopy.

Aerial Equipment:

• Minimum spray volume: 15L/ha using Micronair or boom equipment.
• Droplets with an average size of 250-350 micron diameter are recommended.
• Swath width: 15-17 meters.
• Adjustments for high temperatures: Increase water volume to 30L/ha, increase droplet size to at least 300 micron diameter. Do not apply by aircraft above 35°C.
• Do not use in intensive horticultural cropping areas.

Equipment Maintenance:

• Use stainless steel, aluminum, brass, copper, fiberglass, or plastic-lined containers for mixing, storing, and applying spray solutions.
• Do not use galvanized steel or unlined steel containers or spray tanks, as reactions may produce combustible hydrogen gas.
• Thoroughly clean equipment after use.

Compatibility and Surfactant Addition:

• Compatible with various herbicides, insecticides, and adjuvants as specified in the compatibility and surfactant addition sections.
• Surfactant addition is not recommended except in conservation tillage where it is to be tank-mixed with Glyphosate 450g/L.
• Use specified surfactants or adjuvants according to label directions.

Tank Mixtures:

• Smart Pass 450 Herbicide is designed for tank mixing with Glyphosate 450g/L.
• It can be tank mixed with other herbicides, insecticides, and adjuvants for extended/improved weed control.
• Follow label directions, restraints, plant back periods, withholding periods, and safety directions for tank mix products.

Mixing Instructions:

1. Fill the spray tank with clean water to half of the required amount and start agitation.
2. Add recommended acidifying surfactant if required.
3. Add herbicide additive/insecticide and mix thoroughly.
4. Add Smart Pass 450 Herbicide and mix thoroughly.
5. Add Glyphosate 450g/L and the remaining water.
6. If using non-ionic surfactant, add near the end of the filling process to minimize foaming.
7. Maintain adequate agitation during application and use the tank mix promptly.
