|---|---|
| Brand Name | Diurex® / Durion |
| Technical Name | Diuron (80% WP, SC, or WG) |

Product scienceHow It Works: Mode of Action
Diurex works from the ground up, stopping weeds before they become a problem.
- Root Absorption: When weed seeds sprout, their young roots absorb the Diuron mixed in the soil moisture.
- Systemic Upward Movement: The plant pulls the herbicide up through its stem and straight into its leaves.
- Photosynthesis Blockout: Diuron clogs the weed's ability to turn sunlight into food. The weed yellows, starves, and rapidly dies.
Because it stays in the top layer of the soil, it continues to kill new weed flushes for months.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton (Pre-Emergence) | 300 ml (or 300g WP) | 200 L | 1.5 ml | 365 (Rotation Restrict) |
| Sugarcane | 800 - 1600 ml | 200 L | 4 - 8 ml | Before Canopy Close |
| Citrus & Orchards | 800 - 1000 ml | 200 L | 4 - 5 ml | Non-bearing stage |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply: Best Practices
- Timing: Apply to clean, weed-free soil right before expected rainfall or irrigation so the chemical can wash into the root zone.
- Mixing: Pre-mix the powder or liquid into a small bucket of water to form a paste first. Pour it into a half-filled spray tank and keep it constantly mixing (agitated).
- Coverage: Use a flat-fan nozzle for even spraying. Never overlap your spray passes or stop the tractor while spraying, as doubling the dose will burn your crops.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Keep far away from ponds, as this is extremely toxic to fish.

Frequently Asked Questions
1. Can I use Diurex on sandy soil?
No. Sandy soils don't hold onto the chemical well. It will wash down too deeply and damage the roots of your cash crops. Use it only on heavier, clay or loamy soils.
2. Does it need rain to work?
Yes. Diuron needs moisture to activate. If it doesn't rain within a few days of spraying, you must run irrigation to push the herbicide down into the soil where weed seeds are sprouting.
3. How long should I wait before planting a different crop?
Because Diurex is so long-lasting, you must wait at least one full year before planting a different crop in that same field, unless the new crop is specifically proven to tolerate Diuron.
4. Is it safe to spray near water bodies?
Absolutely not. Diurex is highly toxic to algae and fish. Never let runoff enter ponds, streams, or irrigation ditches.
5. Can I mix Diurex with other weed killers?
Yes! To get broader control, farmers often tank-mix it with knockdown herbicides like Glyphosate or Glufosinate to kill existing weeds while providing a long-term soil barrier.
