- Authority 480 SC is a selective systemic herbicide containing the active ingredient sulfentrazone 48%, produced by the American company FMC. It controls annual, broadleaf and perennial weeds such as purple nutsedge, pigweed (amaranth), lambsquarters, bristly foxtail, purslane and large crabgrass. It is absorbed through the roots and growing points, stopping weed growth and rapidly destroying the plant cells. It is highly effective both pre-emergence and post-emergence, and its excellent stability in the soil gives crops long-lasting protection.
Key Features:
- Effective against annual, broadleaf and perennial weeds.
- Can be applied pre-emergence or post-emergence depending on the weed growth stage.
- Dual action through roots and foliage for maximum efficacy.
- Controls weeds that are resistant to other herbicide groups.
- High soil stability gives a long protection period.
- Easy to use with fast, visible results in the field.

- Spray preferably when weeds are at an early growth stage for the best result.
Plant-Back Interval:
- Do not plant or irrigate for at least 14 days after spraying to allow herbicide residues in the soil to break down and avoid any effect on the new crop.
Usage Notes:
- Make sure the sprayer is clean and free of other pesticide residues before use.
- Do not apply in high temperatures or windy conditions.
- Avoid irrigation or rainfall within one week of spraying to ensure full efficacy.
- Do not graze animals or use treated vegetation as feed after application.
- Avoid spray drift onto neighboring fields or sensitive crops.
Precautions:
- Wear gloves and a mask while mixing and spraying.

- Store in a cool, dry place away from food, feed and children.
- Do not tank-mix without a prior compatibility test.
Orkida Tip:
- Authority 480 SC is one of the best options for preparing land before planting: it removes weeds down to the roots and leaves the soil clean and ready for germination, reducing manual tillage and supporting strong crop growth.
