How It Works: Mode of Action
Cuman L works as a "shotgun" against fungi. It does not enter the plant; instead, it sits on the surface and creates a chemical barrier.
- Contact Protection: It covers the leaf surface. When a fungal spore lands and tries to germinate, it absorbs the Ziram.
- Multi-Site Attack: Once absorbed, it attacks the fungus at multiple points—stopping energy production (respiration) and protein building.
- Spore Killer: It prevents the spore from growing a "germ tube," effectively stopping the infection before it starts.
Because it attacks so many parts of the fungus at once, it is nearly impossible for diseases to develop resistance to Cuman L.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Apple | Apple Scab (Venturia inaequalis) |
| Grape | Downy Mildew, Anthracnose (Bird's Eye Rot) |
| Tomato & Potato | Early Blight (Alternaria solani) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Coverage is key because this is a contact fungicide.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Apple | 1000 - 1500 ml | 400+ L (Tree coverage) | 3.0 - 3.5 ml | 21 Days |
| Grape | 800 - 1200 ml | 300 - 400 L | 2.0 - 3.0 ml | As per export guidelines |
| Tomato / Potato | 600 - 900 ml | 200 L | 2.0 - 3.0 ml | 3 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Use preventatively! Spray before disease spreads. For Apples, spray from Green Tip to Petal Fall.
- Mixing: Fill tank half with water, add Cuman L, agitate, then add remaining water. It mixes easily without clumping.
- Coverage: Use Hollow Cone nozzles. Ensure both sides of leaves are coated. If you miss a spot, the fungus can enter there.
- Safety: Always wear PPE (gloves, mask, goggles). Cuman L is irritating to eyes—protect them! Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Cuman L with other fungicides?
Yes, it is an excellent tank-mix partner for systemic fungicides (like Metalaxyl or Hexaconazole) to manage resistance. However, NEVER mix it with Lime Sulfur or Bordeaux mixture.
2. Is Cuman L better than Ziram Powder (WP)?
Yes. Cuman L is a liquid (SC), so it produces no dust (safer for you), mixes instantly, and covers the leaf surface better than powders.
3. What is the approximate price of Syngenta Cuman L?
The 1 Liter bottle typically retails between ₹525 and ₹615, making it a very cost-effective solution compared to premium systemic sprays.
4. Does it cure disease that is already visible?
No. Cuman L is a protectant. It prevents spores from entering the plant. For established infections, mix it with a curative (systemic) fungicide.
5. Can I use it on Tomatoes during harvest?
Yes! The Pre-Harvest Interval (PHI) for tomatoes is only 3 days, so you can spray, wait 72 hours, and then harvest safely.
