Tanoshi Herbicide (Metribuzin 70% WP): Complete Guide
An advanced, broad-spectrum solution for effective weed control in Wheat, Potato, Soybean, and Sugarcane.
Tanoshi (Metribuzin 70% WP) by IFFCO MC is a trusted herbicide designed to tackle tough weeds that reduce your crop yield. By combining Japanese technical expertise with IFFCO’s reliable distribution, Tanoshi offers a powerful defense against both grasses and broadleaf weeds. It is especially effective against resistant weeds like Phalaris minor (Gulli Danda) in wheat.
Note: Tanoshi works best when applied with precision. It stops photosynthesis in weeds, starving them to death while keeping your main crop safe.

How It Works: Mode of Action
Tanoshi acts as a Photosystem II Inhibitor. In simple terms, it stops the weeds from generating energy from sunlight.
- Absorption: The herbicide is absorbed through the roots (from soil) and leaves (from spray) of the weeds.
- Blockage: It moves inside the plant and blocks the electron transport chain in the chloroplasts.
- Elimination: Without energy, the weed's cell membranes break down. The weed turns yellow (chlorosis), dries up, and dies.
Note: Tolerant crops like Potato and Sugarcane have special enzymes that detoxify Tanoshi, keeping them safe while the weeds die.

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) | Approx. Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 80 - 120 g | 100 - 120 L | ~1.0 g/L | 120 |
| Potato | 250 - 300 g | 200 - 400 L | ~0.75 - 1.25 g/L | 30 |
| Sugarcane | 300 - 400 g | 300 - 400 L | ~1.0 g/L | 60 |
| Soybean | 200 - 300 g | 200 - 300 L | ~1.0 g/L | 30 |
| Tomato | 300 g | 300 - 400 L | ~0.75 - 1.0 g/L | 30 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage is in Grams (g) because Tanoshi is a powder.
How to Apply: Best Practices
-
Timing:
Wheat: Post-emergence (30-35 Days After Sowing).
Potato/Soybean: Pre-emergence (0-3 Days After Sowing). -
Mixing (The "Thin Paste" Method):
Do not dump the powder directly into the tank. First, mix the required dose in a small bucket with a little water to make a smooth paste. Dissolve all lumps, then pour this into the main spray tank. - Coverage: Use Flat Fan or Flood Jet nozzles for coarse droplets. This prevents drift and ensures the chemical reaches the soil/weeds. Keep agitating (stirring) the tank; if you stop, the powder will settle at the bottom.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Tanoshi on sandy soils?
It is generally discouraged or requires much lower doses. In sandy soils, the chemical washes down too easily to the crop roots, potentially causing damage (phytotoxicity).
2. What is the carryover risk for the next crop?
Be careful. Crops like Mustard, Sunflower, and Cucurbits are very sensitive to Metribuzin residues. If you used Tanoshi in the previous season, ensure a gap of 90-100 days or deep ploughing before planting these.
3. Can I mix Tanoshi with other herbicides?
Yes. In wheat, it is often mixed with Clodinafop or Sulfosulfuron to manage resistant Phalaris minor. However, always conduct a small jar test first.
4. What is the price in Telangana?
While prices vary by dealer, small packs (100g) generally range between ₹164 and ₹200. IFFCO Bazar outlets sell at transparent MRP rates.
5. What happens if I spray a double dose?
Do not overlap spray passes. A double dose will likely burn your crop. Stick strictly to the recommended dose per acre.
