Rekishi Herbicide (Sulfosulfuron 75% WG): The Wheat Protection Expert
Stop Phalaris minor (Mandusi/Gulli Danda) and tough broadleaf weeds in their tracks with Rekishi.
Rekishi (by IFFCO-MC) is a premium systemic herbicide designed specifically for wheat farmers. Using advanced Japanese technology, it targets resistant weeds that mimic wheat, ensuring your crop gets all the nutrition without competition. It is the ultimate solution for the "Phalaris-Chenopodium" weed complex in the Indo-Gangetic plains.
Best For: Wheat crops facing heavy infestation of grassy and broadleaf weeds.
Why Choose This Product? Key Benefits
- ⏱️Early Control: Stops weed growth immediately within 48 hours of application, even if visible yellowing takes a few days.
- ?️Wheat Safe: Specially formulated to be safe for wheat plants (due to rapid metabolism) while being deadly to weeds.
- ⏳Long-Lasting Action: Provides residual soil activity that prevents late-germinating weeds from emerging later in the season.
- ?️Systemic Power: Absorbed by both roots and leaves (Dual Action), ensuring total kill even in difficult weather conditions.
- ?Broad Spectrum: One shot controls both tough grasses (like Canary Grass) and broadleaf weeds (like Bathua).

How It Works: Mode of Action
Rekishi works by starving the weed. It inhibits the ALS enzyme, which acts as a "food factory" for essential amino acids. Without these, the weed cannot grow or divide cells.
- Absorption: The herbicide is rapidly absorbed through the leaves and roots, moving via the plant's vascular system (Xylem and Phloem).
- Stoppage: Essential amino acid production (Valine, Leucine) stops. The weed stops growing within 48 hours.
- Elimination: Leaves turn yellow (chlorosis), veins turn purple, and the growing point dies. Complete plant death occurs in 14-21 days.
Note: Wheat plants naturally break down this chemical, making them immune to the spray.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Phalaris minor (Little Seed Canary Grass / Mandusi) |
| Wheat | Chenopodium album (Bathua), Melilotus (Sweet Clover) |
| Wheat | Rumex spp. (Jangli Palak / Dock) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less water or the wrong nozzle will reduce efficacy.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Surfactant (ml / Acre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 13.5 g (1 Sachet) | 100 - 120 Liters | 500 ml | 110 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: The 13.5g sachet is pre-measured for exactly one acre.
How to Apply: Best Practices
- Timing: Apply 30 to 35 Days After Sowing (DAS). This is typically 3-5 days after the first irrigation when the soil is moist (at field capacity). Do not delay beyond the 4-leaf stage of the weed.
- Mixing: Always use the surfactant provided. Dissolve the granules in a small bucket of water first, then add to the main tank. Add surfactant last to avoid foam.
- Coverage: Use a "Flat Fan" or "Flood Jet" nozzle. Do not use cone nozzles (mist blowers) as they cause drift and poor coverage on grass weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I plant Maize, Jowar, or Cotton after using Rekishi?
No. This herbicide leaves residues that can harm sensitive crops like Maize, Sorghum, or Cotton in the next season. It is safe for Wheat-Rice rotations.
2. Can I mix Rekishi with 2,4-D for more broadleaf control?
No. Mixing with 2,4-D reduces the effectiveness against grassy weeds (antagonism). If you need to mix, use Metsulfuron instead of 2,4-D.
3. What if I spray it on dry soil?
Efficacy will be very poor. Moisture is required for the roots to absorb the chemical and for the weeds to be metabolically active. Always spray after first irrigation.
4. Can I use this in alkaline soils?
Avoid using in soils with pH higher than 8.5. In high pH soils, the chemical does not degrade easily and can damage future crops for more than a year.
5. Does it kill Wild Oats (Jangli Jai)?
It provides suppression but may not fully kill heavy infestations of Wild Oats. It is primarily for Phalaris minor and broadleaf weeds.
