RANMAN TOP

Molecular Mechanism: A Shield Against Oomycetes

At the heart of "Ranman TOP" lies cyazofamid, a unique active ingredient from the cyanoimidazole class. Its key technical advantage is its ability to inhibit the mitochondrial respiration of pathogens at the Qi-site of complex III. Unlike standard fungicides, cyazofamid suppresses oomycetes at every stage of their lifecycle, from spore germination to zoosporangia formation, providing a complete stop to the infection process.

Why the Contact Formulation Matters

Ranman TOP is formulated as a suspension concentrate, which, upon application, creates a highly durable protective film on the leaf surface. Due to specialized adjuvants, the product exhibits unique rainfastness (resistant to wash-off within 15–30 minutes of drying). In practical terms, this is crucial when operating in unpredictable climates where the risk of late blight or downy mildew is at its peak.

Operational Guidelines and Crop Protection

The product shows superior performance on cucumbers, tomatoes, and potatoes. As a contact fungicide, uniform coverage of the leaf area is essential for maximum efficacy.

• Active Ingredient: Cyazofamid.
• Application Regimen: Allows 3–6 treatments per season depending on the phytosanitary pressure.
• Pre-Harvest Interval (PHI): Only 7 days, allowing for high flexibility in harvest logistics.
• Dosage: 0.5 L/ha, offering a cost-effective solution for intensive agricultural systems.

The synergy of expertise from ISK Biosciences Europe, N.V. and Arysta LifeScience S.A.S. has resulted in a product that does more than just protect plant tissues—it actively prevents secondary infections by blocking mobile zoospores. When applied within the 3rd hazard class safety guidelines, Ranman TOP provides consistent control without the risk of resistance, making it a cornerstone in modern vegetable protection schemes.
