How It Works: Mode of Action
Yujo uses a "Synergistic" approach, meaning the two chemicals work better together than they do alone.
- Systemic & Vapor Attack (Chlorpyrifos): It enters the insect's system and inhibits the AChE enzyme, causing nervous system failure. Its strong vapor action also kills pests hiding inside canopy/bolls.
- Contact Shock (Cypermethrin): It attacks the sodium channels in the insect's nerves, causing immediate paralysis and a "knockdown" effect.
- Double Lock: While Cypermethrin stops the pest from moving, Chlorpyrifos ensures it dies. This prevents pests from recovering (resurgence).
This combination makes it highly effective against pests that have developed resistance to single chemicals.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Aphids, Jassids, Thrips, Whitefly, Spodoptera, Spotted Bollworm, Pink Bollworm, American Bollworm |
| Paddy (Rice) | Yellow Stem Borer (Dead Heart), Leaf Folder |
| Vegetables (Brinjal/Okra) | Shoot Borer, Fruit Borer (Note: Observe strict PHI) |
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) |
|---|---|---|---|---|
| Cotton | 400 - 500 ml | 200 - 400 L | 2.0 - 2.5 ml | 15 Days |
| Paddy (Rice) | 250 - 300 ml | 200 - 300 L | 1.5 - 2.0 ml | 15 Days |
| Brinjal / Okra | 350 - 400 ml | 200 L | 1.5 - 2.0 ml | 15 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 when pest population crosses the Economic Threshold Level (ETL)—e.g., when you see 5-10% damage. Best sprayed in early morning or late evening.
- Mixing: Premix the required quantity in a small bucket of water before adding it to the main spray tank. Agitate well.
- Coverage: Use a hollow cone nozzle for best foliage coverage. Ensure the spray reaches the underside of leaves and developing bolls.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying against the wind.
Frequently Asked Questions
1. What is the price of Yujo (505) Insecticide?
The price varies by region and dealer, but a 1-liter bottle typically costs between ₹660 and ₹760 in markets like Telangana and Andhra Pradesh. Smaller packs (100ml, 250ml) are also available.
2. Are there any crops where I cannot use Yujo?
Yes. Due to regulatory bans, do NOT use this product on Ber (Jujube), Citrus fruits, or Tobacco. Also, avoid use on export-oriented crops due to strict residue limits.
3. Is Yujo safe for bees and fish?
No. Yujo is toxic to bees and fish. Do not spray during peak flowering times when bees are active, and ensure run-off does not enter fish ponds or aquaculture bodies.
4. What is the antidote for accidental poisoning?
In case of ingestion or severe exposure, immediate medical attention is required. The specific antidote is Atropine Sulphate (for the Chlorpyrifos component), administered by a doctor.
5. How long before harvest should I stop spraying?
You must stop spraying at least 15 days before harvesting (PHI). This ensures that chemical residues drop to safe levels before the crop reaches the market.
