Broad-spectrum fungicidal activity against key oomycete and fungal pathogens including Phytophthora, Pythium, and downy mildews.
Systemic and translaminar movement ensures effective protection of new growth and underside leaf surfaces.
Low application rates with high efficacy support sustainable use and reduced environmental impact.
Compatible with integrated pest management (IPM) programs and multiple crop protection chemistries.
Stable formulation with excellent tank-mix compatibility and rainfastness within 2 hours after application.
Vineyards for control of grapevine downy mildew (Plasmopara viticola).
Tomato and cucumber production in protected cultivation (greenhouses and tunnels).
Leafy vegetables including lettuce and spinach to manage Peronospora spp.
Ornamental nurseries targeting Phytophthora root rot and foliar blights.
Seedling propagation systems where pre- and post-emergence damping-off prevention is critical.

Q1: What is the primary mode of action of Dow AQUCAR IG 50 Fungicide?
A: Dow AQUCAR IG 50 Fungicide functions as a broad-spectrum, contact and protective fungicide. It inhibits fungal growth by disrupting cell membrane integrity and interfering with essential metabolic processes in susceptible organisms.
Q2: In which types of industrial water systems is AQUCAR IG 50 typically applied?
A: It is commonly used in recirculating cooling water systems, process water loops, and other non-potable industrial water applications where microbial fouling—particularly mold, yeast, and filamentous fungi—poses operational or quality risks.
Q3: How is AQUCAR IG 50 typically dosed in water treatment formulations?
A: Dosage depends on system conditions, microbial load, and water chemistry. It is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in formulated biocide blends—and is often applied continuously or intermittently based on monitoring and control protocols.
Q4: Is AQUCAR IG 50 compatible with common corrosion inhibitors and scale control agents?
A: Yes, AQUCAR IG 50 demonstrates good compatibility with many standard water treatment additives—including phosphonates, azoles, and polyacrylates—when used within recommended pH and temperature ranges. Compatibility testing under actual system conditions is advised prior to full-scale implementation.
Q5: What safety and handling precautions should be observed when working with this product?
A: As with all industrial biocides, appropriate personal protective equipment (PPE)—including chemical-resistant gloves, goggles, and protective clothing—should be worn during handling. Avoid inhalation of mists or vapors and prevent skin and eye contact. Refer to the Safety Data Sheet (SDS) for detailed toxicological information and first-aid measures.
