Durion Herbicide (Diuron 80% WP) | Broad-Spectrum Weed Control
The ultimate "Labour Replacement" solution for Cotton, Sugarcane, and Plantation crops.
Durion (Diuron 80% WP) by Insecticides (India) Limited is a powerful pre-emergence herbicide designed to keep your fields weed-free for months. In an era where manual weeding is expensive and labor is hard to find, Durion offers a cost-effective alternative. It works by creating a chemical barrier in the soil that stops weeds before they can grow, ensuring your crop gets all the nutrients it needs without competition.
Best For: Farmers seeking long-term residual control of both grasses and broadleaf weeds in long-duration crops.

How It Works: Mode of Action
Durion acts as a systemic herbicide that targets the weed's ability to create energy from sunlight.
- Absorption: When applied to the soil, the herbicide is absorbed by the roots of germinating weed seedlings.
- Blockage: It moves upward into the leaves and blocks Photosystem II (a critical part of photosynthesis). This stops the plant from converting sunlight into energy.
- Elimination: Starved of energy, the weed seedling turns yellow (chlorosis), then brown (necrosis), and finally dies before it can compete with your crop.
Note: Because it attacks photosynthesis, weeds must emerge and be exposed to light for the final kill to happen.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Carpet weed (Trianthema), Pigweed (Amaranthus), Barnyard grass. |
| Sugarcane | Morning Glory (Convolvulus), Purslane, Barnyard grass, various broadleaves. |
| Plantations (Tea, Coffee, Rubber) | Mixed weed flora (Grass and Broadleaf complex). |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 300g - 600g (Depending on soil type) | 200 - 300 Litres | 1.5g - 2g | 60-90 |
| Sugarcane | 650g - 1300g | 200 - 300 Litres | 3.25g - 4.5g | 90+ |
| Plantation Crops | 600g - 1000g | 300 Litres | 2g - 3.5g | Before Fruit Set |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Use higher water volume (200L+) to ensure good soil coverage.
How to Apply: Best Practices
- Timing: For Cotton, spray strictly within 0-3 days of sowing (Pre-emergence). For Sugarcane, it can be used pre-emergence or early post-emergence.
- Mixing: This is a Wettable Powder (WP). Always make a "slurry" (thick paste) in a bucket with a little water first, then add it to the main tank. Keep the tank agitated.
- Coverage: Use a Flat Fan or Floodjet nozzle. Ensure the soil is moist at the time of application for the chemical to bind properly.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spray drift onto standing crops.
Frequently Asked Questions
1. Can I use Durion on sandy soil?
Yes, but use the lower dosage (approx. 300g/acre). Sandy soils hold less chemical, so high doses can leach down and damage the crop roots.
2. What happens if I spray after the cotton has sprouted?
Do not do this. Durion can cause severe burning or death to young cotton seedlings if sprayed on the leaves. Apply only to the soil before emergence.
3. How long should I wait before planting the next crop?
Durion has long soil persistence. Avoid planting sensitive crops like sunflower, sesame, or vegetables immediately after the harvest of a Durion-treated crop.
4. Does it control grown weeds?
It is most effective on germinating seeds and very small seedlings. For large, established weeds, you may need a different post-emergence herbicide.
5. Can I mix it with other herbicides?
Yes, it is often rotated or tank-mixed with Pendimethalin for enhanced resistance management, but always check compatibility first.
