Karathane Gold Fungicide (Meptyldinocap 35.7% EC)

The Specialist Solution for Powdery Mildew and Mite Suppression in Grapes, Mangoes, and Chilies.

Karathane Gold is a powerful, contact-based fungicide developed by Corteva Agriscience. It is specifically designed to control Powdery Mildew (Erysiphales) effectively, even when other products fail due to cold weather. Unlike older chemistries, it uses Meptyldinocap, a safer and more precise active ingredient that eradicates fungus on leaves, fruits, and woody stems.

Best For: Farmers looking for a "cleanup" spray that works in low temperatures and helps prevent resistance buildup in high-value crops.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Curative & Eradicant Action: It doesn't just protect; it stops active disease. It effectively burns off existing fungal growth (mycelium) on contact.
  • ?️ Resistance Fighter: An ideal rotation partner. It kills fungal spores that have become resistant to systemic fungicides (like Azoles), resetting your crop's protection.
  • Woody Part Sanitation: Unique ability to sanitize woody stems and canes, destroying overwintering fungus to ensure a disease-free start for the next season.
  • ?️ Cold Weather Expert: Unlike Sulfur, which requires heat to work, Karathane Gold remains highly effective during cool winters and early mornings.
  • ? Dual Action (Mite Control): While primarily a fungicide, it possesses significant acaricidal properties, suppressing Mite populations alongside Powdery Mildew.

Product scienceHow It Works: Mode of Action

Karathane Gold works by disrupting the energy balance of the fungal cell (Uncoupling of Oxidative Phosphorylation).

  1. Contact & Absorption: The spray lands on the leaf and sticks to the fungal body and waxy cuticle.
  2. Energy Blockade: Meptyldinocap enters the fungal mitochondria (the power plant of the cell) and causes a "short circuit" in energy production.
  3. Rapid Death: Unable to produce ATP (energy), the fungus cannot grow, breathe, or feed, leading to rapid cell collapse and death.

Since this is a physical disruption of energy, it is very difficult for fungi to develop resistance against it.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results.

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.

Useful detailsHow to Apply: Best Practices
  • Timing: Apply as a preventive spray or at the first sign of white powdery patches. Ideal for cool weather conditions when sulfur is ineffective.
  • Mixing: Fill the spray tank with half the required water, add the measured Karathane Gold, and mix well. Do not mix with oil-based formulations to avoid leaf burn.
  • Coverage: This is a contact fungicide. Ensure thorough coverage of leaves (top and bottom), fruit bunches, and woody stems for best results.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near water bodies.
