Description

Metam Sodium is a versatile soil fumigant and broad-spectrum biocide widely used in agricultural and industrial applications. Its primary value lies in its ability to effectively control a wide range of soil-borne pests, pathogens, and weeds, thereby improving crop yield and quality. This product is essential for professional growers in agriculture and horticulture, as well as for industrial site remediation and sanitation processes.

Application

• Pre-plant Soil Fumigation: Primary application for controlling nematodes, fungi, insects, and weed seeds in agricultural fields, greenhouses, and nurseries prior to planting high-value crops.
• Commodity and Storage Facility Treatment: Used for the sanitation and disinfestation of warehouses, grain silos, and food processing facilities to eliminate pests and mold.
• Soilborne Disease Management: Effective against pathogens causing diseases like Verticillium wilt, Fusarium wilt, and damping-off in various crops.
• Nematode Control: A key solution for managing root-knot, cyst, and other parasitic nematodes that damage plant root systems.
• Weed Seed Bank Reduction: Suppresses annual and perennial weed seeds in the soil, reducing competition for crops.
• Industrial Site Remediation: Applied for soil sterilization in contaminated land reclamation and at industrial sites requiring bioburden reduction.
• Greenhouse and Nursery Bed Preparation: Ensures clean, pest-free growth media for seedlings and transplants in controlled environments.

Quality Control

Our Metam Sodium is manufactured under strict quality management systems to ensure batch-to-batch consistency and efficacy. The product undergoes rigorous analytical testing, including assay by titration and impurity profiling, to meet defined agricultural-grade specifications. A Certificate of Analysis (COA) detailing purity, density, and other critical parameters is provided with each shipment to guarantee compliance with your application requirements.

Storage

Preserve in a tightly closed, corrosion-resistant container, protected from light and stored in a cool, well-ventilated area. The product should be kept away from strong acids and oxidizing agents. Store at temperatures between 15°C and 25°C (59°F and 77°F) to maintain stability and prevent decomposition. Keep the container tightly sealed when not in use to minimize exposure to moisture and air.
