Description

Metalaxyl-Mancozeb is a synergistic, broad-spectrum fungicide formulation combining the systemic activity of metalaxyl with the protective, multi-site action of mancozeb. This combination is critical for effective resistance management and provides robust, long-lasting control against a wide range of oomycete and fungal pathogens. It is an essential tool for agricultural professionals and formulators seeking reliable crop protection solutions for high-value fruits, vegetables, and field crops.

Application

• Agricultural Fungicide Formulations: Primary use in the manufacturing of ready-to-use suspension concentrates (SC), wettable powders (WP), and water-dispersible granules (WG) for foliar application.
• Control of Oomycete Diseases: Highly effective against late blight in potatoes and tomatoes (Phytophthora infestans), downy mildews in grapes, cucurbits, and onions, and Pythium damping-off in various seedlings.
• Management of Fungal Diseases: Provides protective control against early blight in potatoes and tomatoes (Alternaria solani), leaf spots, and blights in a wide range of horticultural and field crops.
• Seed Treatment: Used in professional seed coating formulations to protect against soil-borne pathogens during germination and early plant development.
• Resistance Management Programs: Integral component of anti-resistance strategies due to its multi-site (mancozeb) and single-site (metalaxyl) mode of action combination.
• Vegetable and Fruit Production: Key for protecting high-value crops such as grapes, potatoes, tomatoes, cucurbits, and onions from devastating foliar and fruit diseases.

Quality Control

Our Metalaxyl-Mancozeb technical material is manufactured under a strict quality management system. Every batch is analyzed to ensure it meets precise specifications for active ingredient content, particle size distribution, and impurity profiles critical for formulation stability and efficacy. Certificates of Analysis (COA) detailing assay results for both metalaxyl and mancozeb, along with key physical parameters, are provided with each shipment to guarantee consistent quality and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent caking or degradation due to atmospheric moisture. Keep away from heat, sparks, and open flame.
