Metalaxyl 8% + Mancozeb 64% WP

Metalaxyl Mancozeb WP

Metalaxyl Mancozeb WP is a trusted dual-action fungicide that brings together a systemic and a contact fungicide in one wettable powder formulation. This combination ensures double protection for the plant — fighting fungal disease from the inside through Metalaxyl’s systemic activity and from the outside through Mancozeb’s protective contact action, making it one of the most reliable choices for managing tough Oomycete diseases like late blight and downy mildew.

How Metalaxyl Mancozeb WP Works

This fungicide uses a sophisticated two-level approach to control fungus. Metalaxyl is absorbed by the leaves and roots and moves upward through the plant, entering fungal cells and inhibiting RNA synthesis, effectively stopping the fungus from growing or reproducing inside the plant. Mancozeb, on the other hand, stays on the leaf surface and releases compounds that inhibit fungal enzymes, creating a multi-site barrier that kills spores on contact before they can even enter the plant tissue.

Why Farmers Choose This Fungicide

One of the most valuable features of Metalaxyl Mancozeb WP is its curative “kick-back” action, meaning it can stop an infection even when applied 24 to 48 hours after the fungus has already attacked the plant. This gives farmers a safety net even if disease symptoms are spotted slightly late, rather than relying solely on preventive timing. Because the wettable powder formulation is rain-resistant, the fungicide’s protective effect continues even after rainfall, reducing the need for repeat applications during wet weather.

This fungicide is especially valued by grape, potato, and tomato growers for controlling downy mildew and late blight, two of the most economically damaging diseases in these crops. By combining a single-site systemic fungicide with a multi-site contact fungicide, this product also plays an important role in resistance management, making it much harder for fungal pathogens to develop tolerance compared to using either active ingredient alone. Many farmers also report a phytotonic effect, often called the “Green Haulm effect,” which keeps crop foliage greener for longer and directly supports better yield and quality.

Key Benefits

• Controls late blight, downy mildew, leaf spots, and rust
• Also effective against damping off, white rust, and Alternaria blight
• Dual mode of action — systemic and contact protection together
• Curative kick-back action even 24-48 hours after infection
• Rain-resistant protection that persists after rainfall
• Helps manage and prevent fungicide resistance
• Phytotonic effect keeps crop foliage greener for longer

Why Crop Nutrition Matters Alongside Disease Control

Crops recovering from fungal disease pressure benefit from added nutritional support to maintain healthy, productive growth. Products like Humic Acid 98% Flakes help build a stronger root system to support faster recovery, while Power PGR Liquid helps the plant channel its renewed health into better flowering and fruit setting through the rest of the season.

Safety Tips & Precautions

• Wear gloves, goggles, and protective clothing while mixing and spraying
• Avoid direct contact with skin and eyes during application
• Apply preventively before the onset of favorable disease conditions, or as soon as symptoms appear
• Maintain the recommended pre-harvest interval before harvesting for market
• Maintain proper re-entry time into treated fields after each application
• Do not exceed the recommended dose to avoid resistance build-up
• Wash hands thoroughly after handling the product
• Keep away from children, animals, and food or feed storage areas
