Description

Maneb CAS NO 12427-38-2 is a manganese-containing dithiocarbamate fungicide widely recognized for its broad-spectrum protective action. It is a critical tool for controlling a wide range of fungal diseases in numerous crops, safeguarding agricultural yield and quality. This product is essential for agricultural producers, horticulturists, and manufacturers of fungicidal formulations targeting foliar pathogens.

Application

• Agricultural Fungicide: Primary use in protecting field crops such as potatoes, tomatoes, peanuts, and cereals from blights, leaf spots, and rusts.
• Fruit and Vegetable Protection: Applied to control diseases like early and late blight in potatoes and tomatoes, and scab on apples and pears.
• Ornamental and Turf Management: Used in the maintenance of ornamental plants, nurseries, and turfgrass to prevent fungal outbreaks.
• Seed Treatment: Employed as a dressing for seeds to protect against soil-borne fungal pathogens during germination and early seedling growth.
• Formulation Intermediate: Serves as a key active ingredient in the manufacturing of wettable powders, flowable concentrates, and other commercial fungicidal products.
• Disease Resistance Management: Often used in rotation or mixture with other fungicide classes to manage and delay the development of pathogen resistance.

Quality Control

Our Maneb is manufactured under strict quality protocols to ensure batch-to-batch consistency and efficacy. The product undergoes rigorous analytical testing, including assay for active manganese content and dithiocarbamate residue levels, to meet relevant agricultural chemical standards. A Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and degradation. Isolate from strong acids, strong oxidizers, and foodstuffs. Observe local regulations for pesticide storage.
