Crystal Arsa Herbicide (Glufosinate Ammonium 13.5% SL)
The "Blue Triangle" Safety Solution for Tough, Resistant Weeds.
Arsa Herbicide by Crystal Crop Protection is a powerful, broad-spectrum contact herbicide designed for the modern farmer. Formulated with 13.5% Glufosinate Ammonium, it provides a crucial "middle path" between slow-acting systemic weed killers and highly toxic alternatives. Arsa is specifically engineered to control tough weeds that have developed resistance to Glyphosate, making it an essential tool for Tea plantations and Cotton farmers.
Best For: Controlling hard-to-kill weeds like Imperata cylindrica and Commelina without damaging your soil or long-term crop health.
Why Choose This Product? Key Benefits
- ⏱️Rapid Action: Visible yellowing in just 48 hours, with complete weed death in 3 to 5 days.
- ?️Superior Safety Profile: Classified with a "Blue Triangle" (Moderately Toxic), it is significantly safer for users than Red-label herbicides like Paraquat.
- ⏳Resistance Breaker: Highly effective against weeds that no longer die with Glyphosate, such as Eleusine indica and Commelina.
- ?️Rainfastness: Requires a rain-free window of only 4 to 6 hours to ensure full absorption into the weed leaves.
- ?Cost Effective: Reduces weed management costs by approximately 50-60% compared to manual hand-weeding.

| Technical Name | Glufosinate Ammonium 13.5% SL |
| IRAC MoA Code | Group H / 10 (Glutamine Synthetase Inhibitor) |

How It Works: Mode of Action
Arsa acts as a contact herbicide. It utilizes a high concentration of surfactants to penetrate waxy leaves instantly.
- Enzyme Blockade: The active ingredient inhibits the Glutamine Synthetase enzyme within the plant cells.
- Toxicity Buildup: This blockage causes rapid accumulation of Ammonia, which is toxic to the plant cells.
- Plant Collapse: Photosynthesis stops, cell membranes burst, and the weed dries out completely within days.
Note: As a contact herbicide, it only kills the green parts it touches. It does not move deep into roots like Glyphosate, making it safer for usage around tree trunks.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tea Plantations | Imperata cylindrica (Thatch grass), Borreria hispida, Commelina benghalensis |
| Cotton (Inter-Row) | Annual Grasses (Eleusine, Digitaria) and Broadleaf weeds |
| Non-Crop Areas | General vegetation management (fences, pathways, industrial sites) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Arsa requires high water volume for effective coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea | 1000 - 1320 ml | 200 Liters | 5.0 - 6.6 ml | 15 Days |
| Cotton | 1000 - 1200 ml | 200 Liters | 5.0 - 6.0 ml | 96 Days |
| Non-Crop Areas | 1200 ml | 200 Liters | 6.0 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when weeds are young and actively growing (at the 3 to 5 leaf stage) for maximum kill.
- Mixing: Use clean water. Avoid muddy or hard water as it can reduce efficacy. Use a Flat Fan or Flood Jet nozzle for uniform coating.
- Coverage: Since Arsa is a contact herbicide, coverage is king. Ensure you use at least 200 Liters of water per acre to soak the foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Arsa kill the roots of the weeds?
Arsa is primarily a contact herbicide. It rapidly kills all green foliage it touches. While it suppresses root growth significantly, it does not translocate deep into the root system like Glyphosate, making it safer for use near crop roots.
2. How long does it take to see results?
You will see the weeds turning yellow (Chlorosis) within 24-48 hours. Complete drying and death usually occur within 3 to 5 days depending on sunlight intensity.
3. Can I spray this over my Cotton crop?
No. Arsa is a non-selective herbicide. It will damage any green plant it touches. For cotton, you must use a hood/shield on your nozzle to spray between the rows (inter-row) without hitting the cotton plants.
4. Does it leave residue in the soil?
Arsa has a very favorable environmental profile. It is rapidly degraded in the soil by microbes (Half-life of 7-20 days) and does not harm rotational crops grown in the next season.
5. What is the shelf life of the product?
When stored in a cool, dry place in its original packaging, Arsa has a shelf life of 2 years.
