Broad-spectrum systemic and contact fungicidal activity against key ascomycete and basidiomycete pathogens.
Water-dispersible granule (WG) formulation ensures rapid dispersion, uniform suspension, and excellent tank-mix compatibility.
Enhanced rainfastness with strong adhesion to leaf surfaces, maintaining efficacy under variable weather conditions.
Low mammalian toxicity profile, classified as WHO Class U (unlikely to present acute hazard) when used as directed.
Compatible with integrated pest management (IPM) programs due to favorable environmental fate and minimal impact on beneficial arthropods.
Vineyards – control of powdery mildew (Erysiphe necator) and downy mildew (Plasmopara viticola).
Apple orchards – suppression of apple scab (Venturia inaequalis) and summer rots.
Strawberry production – management of gray mold (Botrytis cinerea) and anthracnose (Colletotrichum acutatum).
Cereal crops – protection against Septoria tritici blotch (Zymoseptoria tritici) and rusts (Puccinia spp.).
Protected horticulture (greenhouses and tunnels) – preventive and curative control of foliar fungal diseases on tomatoes and cucurbits.

Q1: What types of fungi does Schülme Grotan WS effectively control?
A: Schülme Grotan WS is a broad-spectrum fungicide formulated to inhibit the growth of common spoilage and deterioration fungi in industrial water-based systems, including Aspergillus, Penicillium, Cladosporium, and various yeasts and molds that compromise product stability and shelf life.
Q2: In which industrial applications is Schülme Grotan WS typically used?
A: It is primarily employed in water-miscible industrial formulations such as metalworking fluids, latex paints and coatings, adhesives, sealants, and aqueous cleaning solutions—where microbial contamination poses risks to performance, viscosity, odor, and end-product integrity.
Q3: How is Schülme Grotan WS incorporated into formulations?
A: As a water-soluble concentrate, it is easily dispersed into aqueous systems during the final stages of manufacturing. Dosage depends on formulation requirements and challenge level, but it is typically used at low concentrations to achieve effective preservation without impacting physical or chemical properties.
Q4: Is Schülme Grotan WS compatible with other common biocides or additives?
A: Yes, Schülme Grotan WS demonstrates good compatibility with many non-oxidizing biocides, corrosion inhibitors, surfactants, and thickeners commonly found in industrial formulations—though compatibility testing under actual use conditions is recommended prior to full-scale implementation.
Q5: What safety and handling considerations apply to Schülme Grotan WS?
A: As with all industrial biocides, appropriate personal protective equipment (PPE) such as gloves and eye protection should be worn during handling. It is supplied as a ready-to-use aqueous solution and should be stored in tightly closed containers away from direct sunlight and extreme temperatures to maintain efficacy.
