Product scienceHow It Works: Mode of Action
Melvin works by stopping the fungus from growing at a cellular level. It targets the "skeleton" of the fungal cell.
- Absorption: The powder mixes with water and is sprayed onto the leaves. The unique formulation ensures it sticks and penetrates the plant skin.
- Translocation: Once inside, it travels upwards through the plant's water system (xylem), reaching even the hidden parts of the plant and new leaves.
- Mitosis Inhibition: It stops the fungal cells from dividing (mitosis). Without cell division, the fungus cannot grow or spread, and it eventually dies.
Note: This systemic movement makes it excellent for curing early-stage infections.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Apple | 300g | 400L+ | 0.75g | 3-14 |
| Grapes / Papaya | 300g | 200-400L | 1g - 1.5g | 7-14 |
| Bottle Gourd | 600g | 200-300L | 2g - 3g | 7-14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply: Best Practices
- Timing: Use preventively (before disease appears) or at the very first sign of infection. For Apple, spray during Pink Bud to Petal Fall stages.
- Mixing: Melvin is a Wettable Powder. Make a slurry (thick paste) in a small mug first, then add it to the half-filled spray tank. Maintain agitation.
- Coverage: Ensure thorough coverage of the foliage. While it moves systemically upward, it does not move downward, so cover the lower leaves well.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.

Frequently Asked Questions
1. Is Melvin safe to use?
Yes, Melvin carries a "Green Label," indicating it is slightly toxic to practically non-toxic for acute exposure. However, long-term exposure requires caution, so always use protective gear.
2. Can I mix Melvin with other products?
It is compatible with most insecticides and fungicides (like Mancozeb). Important: Do NOT mix with alkaline products like Bordeaux Mixture or Lime Sulphur, as they destroy Melvin instantly.
3. How does the "Phytotonic" effect help?
The chemical breakdown of Melvin releases sulphur elements. This acts as a nutrient boost, helping the plant produce more amino acids and chlorophyll, leading to greener leaves.
4. What happens if it rains after spraying?
If it rains 2-4 hours after spraying, you are safe. Melvin is absorbed into the leaf tissue quickly, making it rainfast.
5. Should I use Melvin continuously?
No. To prevent resistance, do not use Melvin more than twice a season. Rotate it with fungicides from different groups (like Triazoles or Mancozeb).
