Himax Herbicide (Glufosinate Ammonium 13.5% SL)
The "Chemical Plough" for Cotton, Tea, and Soybean Farmers.
Himax by Insecticides (India) Limited is a powerful, broad-spectrum post-emergence herbicide. It provides a smart alternative to manual weeding, acting as a "middle path" between slow-acting systemic weed killers and instant burn-down chemicals.
Best For: Farmers seeking cost-effective weed control (saving up to 70% compared to manual labor) while ensuring crop safety in wide-row crops like Cotton and Tea.
Why Choose This Product? Key Benefits
- ⏱️Rapid Action: Visible yellowing of weeds in 2–3 days; complete death (desiccation) in 3–5 days.
- ?️Crop Safety Margin: Ideal for inter-row spraying. Unlike Glyphosate, accidental drift causes only localized spotting, not whole-plant death.
- ⏳No Soil Residue: Degrades in soil within 3–10 days, making it perfectly safe for crop rotation.
- ?️Rainfast in 4 Hours: Contains high-load surfactants (approx. 60%) that resist wash-off from sudden showers.
- ?Controls Resistant Weeds: Highly effective against tough weeds like Parthenium, Amaranthus, and Echinochloa.
Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Himax |
| Technical Name | Glufosinate Ammonium 13.5% SL |
| IRAC MoA Code | Group 10 (Glutamine Synthetase Inhibitor) |
| Chemical Group | Phosphinic Acids |
| Formulation | Soluble Liquid (SL) |
| Toxicity Label | Blue Triangle (Moderately Toxic) |
How It Works: Mode of Action
Himax works by inhibiting the Glutamine Synthetase enzyme in plants. This causes a rapid buildup of toxic ammonia within the weed cells.
[Image of Glufosinate Ammonium mode of action]- Absorption: The specialized surfactants allow the liquid to penetrate waxy leaves instantly.
- Blockade: It stops nitrogen metabolism, leading to "ammonia poisoning" inside the plant.
- Burn Down: Cell membranes rupture, photosynthesis stops, and the weed dries out completely.
Note: Activity is faster in bright sunlight due to increased plant metabolic rates.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Echinochloa spp., Cynodon dactylon (Bermuda Grass), Cyperus rotundus. |
| Tea | Borreria hispida, Imperata cylindrica, Digitaria spp. |
| Soybean (Pre-Plant) | All annual/perennial weeds (Burndown before sowing). |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not cut corners on water volume.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 1000 – 1320 ml | 200 Litres | 5 – 6.5 ml | 96 Days |
| Tea | 1000 – 1320 ml | 200 – 250 Litres | 5 – 6 ml | 15 Days |
| Non-Crop/Industrial | 1200 ml | 200 Litres | 6 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 (2–4 leaf stage) and actively growing. Sunny weather improves results.
- Mixing: Use clean water. Avoid muddy water as it can slightly reduce potency. Use Flat Fan or Flood Jet nozzles for a uniform spray sheet.
- Coverage: Himax is a "Contact Herbicide." It only kills what it touches. Ensure complete wetting of the weed foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Use a spray hood/shield in Cotton to prevent drift onto crop leaves.
Frequently Asked Questions
1. Does Himax kill the main crop?
It is non-selective, meaning it can damage any green plant it touches. However, it is safer than Glyphosate for inter-row spraying because it does not translocate significantly within the crop if minor drift occurs. Always use a hood.
2. How does the cost compare to manual weeding?
Manual weeding can cost ₹3,000–₹4,000 per acre. Himax application (Chemical + Labor) typically costs ₹800–₹1,100 per acre, offering a saving of nearly 70%.
3. What if it rains after spraying?
Himax is rainfast within 4 hours. If it rains after this period, you do not need to re-spray.
4. Can I use it on Parthenium (Congress Grass)?
Yes, Himax is highly effective against Parthenium, burning down the rosettes and preventing flowering.
5. What is the toxicity level?
It carries a Blue Label (Moderately Toxic). It is safer than Red or Yellow labeled herbicides but still requires standard protective gear (mask and gloves).
