1. What Is Kresoxim-Methyl?

• Chemical group: Strobilurin (QoI – Quinone outside Inhibitor)
• Mode of action: Systemic, strong translaminar activity, mainly preventive
• Common formulations: SC (Suspension Concentrate), WG (Water Dispersible Granules)
• Chemical formula: C₁₈H₁₉NO₄

👉 Kresoxim-Methyl is derived from natural wood-decay fungi and is highly effective at preventing fungal infections in their early stages across a wide range of crops.

2. Mode of Action Against Fungal Pathogens

Kresoxim-Methyl inhibits mitochondrial respiration in fungi, blocking energy production → starving the fungus → halting development → gradual death.

• Does not kill immediately, but strongly suppresses spread and infection
• Penetrates leaf surfaces → protects even the undersides
• Produces a “green effect”, enhancing photosynthesis and plant vigor

3. Outstanding Benefits of Kresoxim-Methyl

✅ Excellent disease prevention when sprayed early in the crop cycle
✅ Strong systemic movement, residual effect up to 10–14 days
✅ Rainfast – not easily washed off after rain
✅ Boosts plant immune response and health
✅ Safe for beneficial organisms, high biological safety
✅ Can be combined with curative fungicides for enhanced effect

4. Common Diseases Effectively Controlled

5. Comparison with Other Fungicidal Active Ingredients

📌 Kresoxim-Methyl pairs well with strong curative fungicides like Difenoconazole and Propiconazole for a complete protection strategy.

6. How to Use Kresoxim-Methyl Effectively and Safely

• Recommended dosage: 10–20 ml or 5–10 g per 16 liters of water, depending on product
• Best timing: Spray early in wet/humid weather or at first signs of infection
• Apply thoroughly on both leaf surfaces, especially dense canopies and lower leaves
• Rotate active ingredients after two consecutive applications to prevent resistance
• Do not mix with alkaline substances (e.g., sulfur, lime)

7. Conclusion

Kresoxim-Methyl is a powerful and biologically safe preventive fungicide, ideal for IPM programs, clean production, and sustainable agriculture.

Used at the right rate, time, and in rotation, it helps farmers effectively protect crops, reduce risks, and improve produce quality.

👉 Think of Kresoxim-Methyl as your biological shield at the start of the season – stopping fungal attacks before they start!
