Introduction

Mancozeb 80% WP is a widely used protective contact fungicide formulated as a wettable powder. It contains manganese and zinc ions which not only contribute to plant nutrition but also interfere with fungal metabolism by inhibiting pyruvate oxidation and multiple enzymatic pathways within the pathogen. This multi-site activity reduces the risk of resistance buildup and ensures broad-spectrum efficacy across fungal species.

This formulation is effective in preventing diseases such as:

Downy mildew in grapes and cucurbits
Early blight and late blight in potatoes and tomatoes
Apple scab in pome fruits
Rusts and leaf spots in cereals and vegetables

POMAIS offers this product in various packaging sizes and supports OEM customization for regional markets, including custom artwork, multi-language labeling, and formulation adjustments if needed. It is also suitable for use in seed treatment programs, particularly for cotton, corn, and grains.

Whether you are supplying small-scale growers or commercial plantations, Mancozeb 80% WP delivers consistent preventive protection and market-ready flexibility.

Mode of Action

Mancozeb is a multi-site protective fungicide that acts by inhibiting multiple enzyme systems within fungal cells. Its primary mode of action involves the disruption of pyruvate dehydrogenase and other thiol-containing enzymes, which are essential for fungal respiration and energy production.

Unlike systemic fungicides that target a single site, Mancozeb interferes with several metabolic pathways simultaneously, making it difficult for fungal populations to develop resistance. This characteristic makes it an ideal rotation partner in resistance management programs, especially where other fungicides have lost effectiveness due to overuse.

Key attributes of its mode of action:

Prevents spore germination and penetration into host tissue
No systemic movement, ensuring pathogens are targeted on the leaf surface
Remains effective even under moderate rain when applied properly
Safe to combine with most IDM-compatible fungicides for extended protection

By forming a protective film on the plant surface, Mancozeb 80% WP stops infections before they can establish, helping farmers protect crop health during critical growth stages.

Application Methods & Dosage

Mancozeb 80% WP is applied as a foliar spray to protect plants before fungal infection occurs. As a contact fungicide, thorough and even coverage of plant surfaces is essential for optimal efficacy. It is recommended to begin applications preventively, especially under favorable disease conditions such as high humidity and leaf wetness.

Recommended Usage Guidelines:

Crop	Target Disease	Dosage Range	Application Frequency	Notes
Grapevine	Downy mildew	2000–3000 g/ha	Every 7–10 days	Start before symptoms appear
Apple	Scab	1000–1500 mg/kg water	2–4 applications per season	Rotate with systemic fungicide
Potato	Early blight	400–600 ppm solution	3–5 applications	At 7–10 day intervals
Tomato	Late blight	400–600 ppm solution	3–5 applications	Avoid spraying during rain
Cucurbits	Downy mildew	1500–2500 g/ha	Preventive, every 10 days	Ensure full leaf coverage

Best Practices:

Mix required amount of Mancozeb 80% WP with clean water and stir until fully dispersed.
Apply using knapsack, tractor-mounted, or mist blower sprayers.
Do not exceed recommended dosage. Overuse may cause visible residues or crop stress.
Observe pre-harvest intervals (PHI) specific to each crop and local regulations.

Proper rotation with fungicides of different modes of action is recommended to delay the development of resistance and extend product efficacy over the season.

Compatible With:

Systemic fungicides such as metalaxyl, dimethomorph, and cymoxanil
Contact insecticides such as chlorpyrifos or bifenthrin
Water-soluble micronutrients under neutral to slightly acidic conditions

Avoid Mixing With:

Strong alkaline solutions (pH > 9), which may degrade the active ingredient
Copper-based fungicides or lime-sulfur preparations, which may cause phytotoxicity
Fertilizers containing ammonia or other volatile nitrogen sources

Safety Guidelines for Application:

Wear appropriate protective clothing, gloves, and goggles during mixing and spraying
Avoid inhalation of powder or spray mist; work in ventilated areas
Do not spray during windy conditions to prevent drift
Observe re-entry interval (REI) and pre-harvest interval (PHI) as per label instructions
Do not contaminate water bodies; product is toxic to fish and aquatic organisms

Safe handling and correct mixing protocols not only protect the applicator but also preserve crop health and ecosystem balance. Always refer to local agricultural authority guidelines when using tank mixes or planning multi-product applications.

Field Use Scenarios

Mancozeb 80% WP is widely applied in commercial agriculture across fruit orchards, vegetable farms, and staple crop fields. Its broad-spectrum disease control, tank mix flexibility, and preventive action make it a core product in crop protection programs worldwide.

Grapevine Downy Mildew – Southern Europe

In coastal vineyards during the rainy season, growers face repeated outbreaks of Plasmopara viticola (downy mildew). By applying 2500 g/ha of Mancozeb 80% WP every 7–10 days, farmers maintain clean foliage and reduce disease incidence by over 80%. The protective film formed on leaves withstands moderate rainfall and provides residual protection.

Apple Scab Prevention – Central Asia

In apple orchards affected by Venturia inaequalis, early-season sprays at 1000–1200 mg/kg water dilution effectively suppress fungal spore development on leaves and fruit. Mancozeb is rotated with systemic fungicides to reduce resistance pressure and ensure long-term orchard health.

Potato Early Blight – Eastern Africa

In mid-altitude potato-growing areas, farmers report excellent results with 500 ppm Mancozeb solution sprayed at 7-day intervals during flowering and tuber bulking stages. Foliar lesions are significantly reduced, and marketable yield increases by 10–15% compared to untreated plots.

Tomato Late Blight in Greenhouses – Middle East

Greenhouse tomato growers use 600 ppm foliar sprays during periods of high humidity. Mancozeb is integrated with ventilation and irrigation management as part of a complete late blight prevention program, resulting in cleaner fruit sets and lower fungicide resistance development.

These examples demonstrate how Mancozeb 80% WP performs reliably in diverse climatic zones and production systems, helping reduce crop loss and improve disease management consistency for professional users and distributors alike.
