Mancozeb 80% WP | Multi-Site Protective Fungicide for Broad-Spectrum Crop Protection

Mancozeb 80% WP is a broad-spectrum, protectant fungicide formulated as a wettable powder. It belongs to the dithiocarbamate class and works by interfering with multiple enzyme systems in fungal cells, making it highly effective and resistant to pathogen mutation. Its multi-site mode of action ensures long-term disease control with minimal resistance buildup—making it a valuable component in any integrated disease management program.

This product is commonly applied as a foliar spray, offering uniform leaf surface coverage and protection from spore germination. You can also use it for seed treatment to protect against soil-borne and early-stage diseases.

Mode of Action

Mancozeb functions as a multi-site contact fungicide, meaning it interferes with multiple metabolic processes in fungal cells simultaneously. It inhibits key enzymes that contain sulfhydryl (–SH) groups, such as those involved in respiration and lipid metabolism. By targeting various points in the fungal life cycle, it effectively prevents:

• Spore germination

• Hyphal growth

• Fungal enzyme activity

Because Mancozeb does not act at a single biochemical site, it has an exceptionally low risk of resistance development. This makes it especially valuable in long-term crop protection programs and as a rotation partner in integrated fungicide strategies.

Unlike systemic fungicides, Mancozeb stays on the plant surface after spraying, creating a protective barrier that prevents new infections. For best results, it should be applied before visible disease symptoms or early in the infection cycle.

Benefits of Multi-Site Action:

• Slows down resistance buildup in fungal populations

• Ideal for use in fungicide rotation or tank-mixing programs

• Suitable for protective spraying across multiple crops and climates

This versatile mechanism is why Mancozeb remains one of the most widely used protectant fungicides globally—offering peace of mind and crop reliability to farmers and distributors alike.

Mancozeb 80% WP delivers broad-spectrum protection across a wide variety of crops, making it an essential tool for both large-scale agriculture and specialized crop systems. It is especially effective in warm, humid environments where fungal pathogens thrive, and is widely used by growers and distributors in tropical, subtropical, and temperate regions.

Key Target Diseases:

• Early & Late Blight (Phytophthora infestans, Alternaria solani) – Potatoes, Tomatoes
