Mainichi Propargite 57% EC Acaricide (IFFCO-MC)
The "Resistance Breaker" for total mite control in Tea, Chilli, and Apple.
Mainichi (Propargite 57% EC) is a powerful, broad-spectrum miticide brought to you by the IFFCO-MC joint venture. Designed with Japanese technology, it specializes in breaking resistance cycles where other chemicals fail. It targets all damaging mites—including Red Spider Mite and Yellow Mite—using a unique triple-action formula that works through contact, residue, and vapor to clean out hidden pests.
Best For: Farmers facing stubborn mite infestations in Tea, Chilli, Apple, and Brinjal crops.
Why Choose This Product? Key Benefits
-
⏱️
Stops Damage Instantly: Mites stop feeding immediately upon contact, saving your leaves from further "bronzing" or curling.
-
🛡️
Resistance Breaker: Works on mites that have developed immunity to other common acaricides (Group 12C chemistry).
-
⏳
Long-Lasting Control: Provides residual protection for 10 to 14 days against crawling nymphs and larvae.
-
🌧️
Hidden Reach (Vapor Action): Releases vapors that penetrate deep into webs and under leaves to kill hidden mites.
-
🌿
Harvest Friendly: Short waiting period (PHI) of just 7 days for Tea and Chilli, ensuring your harvest schedule stays on track.

How It Works: Mode of Action
Mainichi attacks the mite's energy production center (mitochondria). It cuts off the power supply (ATP), leading to paralysis and death. It uses a "Triple Action" strategy:
- Direct Contact: Kills mites immediately when sprayed directly on them.
- Residual Action: Stays on the leaf surface to kill walking nymphs for up to 14 days.
- Vapor/Fumigant Action: When the sun warms the crop (>20°C), Mainichi releases vapors that travel inside the thick webs and under leaves to kill mites the spray missed.
Note: While it doesn't kill eggs directly, it creates a "larvicidal barrier" that kills the babies immediately as they hatch.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|

| Apple | European Red Mite, Two-spotted Spider Mite |
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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea | 300 – 500 ml | 160 L | 2.5 – 3 ml | 7 Days |
| Chilli | 600 ml | 200 – 250 L | 2.5 – 3 ml | 7 Days |
| Brinjal | 400 ml | 160 L | 2.5 ml | 6 Days |
| Apple | N/A (Tree Basis) | 10 L / Tree | 0.5 – 1 ml | 9 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply early in the morning or late evening. Avoid spraying when the temperature is above 35°C to prevent leaf burn.
- Mixing: Do NOT mix with any oil-based products or alkaline substances (like Bordeaux mixture). This will cause severe crop damage.
- Coverage: Ensure full coverage, especially on the underside of leaves where mites hide. Use plenty of water (as per the table above).
- Safety: Always wear PPE (gloves, mask, goggles). This product is irritating to skin and eyes. Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Mainichi with sticking agents or oils?
You can use a silicon spreader, BUT strictly avoid mixing with petroleum oils or applying it within 30 days of an oil spray. Mixing with oil causes severe leaf burn (phytotoxicity).
2. Does it kill mite eggs?
No, it is not a direct egg killer (ovicide). However, its residual action kills the baby mites (larvae) the moment they hatch from the eggs, breaking the lifecycle effectively.
3. Is it safe for Tea plucking?
Yes, if you follow the instructions. The Pre-Harvest Interval (PHI) is 7 days. You must wait at least 7 days after spraying before plucking the tea leaves.
4. Why is the water volume so high?
Mites hide deep in the canopy and under leaves. High water volume ensures the chemical reaches these hidden spots. For Tea/Chilli, 400-500 Liters per hectare (approx 160-200L per acre) is necessary for results.
5. Is this the same as Mainichi Bio?
No. Mainichi Propargite 57% EC is a synthetic chemical (Yellow Triangle). Mainichi Bio is a different organic product. Do not confuse the two; this page is for the chemical acaricide.
