Microthiol Special

Reliable crop protection: sulfur in a modern formulation

The French-made "Microthiol Special" from Церексагрі (Cerexagri) is a time-tested tool for controlling powdery mildew and mites. Unlike traditional sulfur powders, these water-dispersible granules dissolve perfectly, preventing nozzle clogging and ensuring uniform coverage of the leaf surface.

Applications and Targets

Agronomists rely on this product for both preventive and curative treatments, aiming to suppress pathogens while minimizing the chemical load on the crop. Key use cases include:

• Vineyards: A cornerstone of anti-resistance programs against oidium.
• Orchards: An effective barrier against apple and pear scab during peak growth periods.
• Berry patches: Protection for currants and gooseberries against powdery mildew.
• Vegetables: Clubroot control on cabbage.

Furthermore, the sulfur component provides strong acaricidal effects, helping to suppress spider mite populations, making it a versatile choice for integrated pest management.

Best Practices for Field Use

This is a contact fungicide, creating a protective barrier on the plant surface. Therefore, the quality of coverage is critical—spraying must be thorough and uniform. With a pre-harvest interval of only 1–3 days, it is safe to apply even as fruit approaches maturity.

With a dosage rate of 3.0–4.0 kg/ha (depending on infection levels), the product allows for up to 6 applications per season. Classified as Hazard Class 3, it is relatively safe for personnel but requires standard protective equipment. Note that sulfur is most active at temperatures above 18°C; schedule applications during sunny periods, avoiding extreme heat for best results.
