MANCOZEB DG 2kg

Barmac Mancozeb DG Fungicide 2kg is a dry flowable preventative fungicide containing 750 g/kg mancozeb. It provides multi-site protection against a wide range of fungal diseases across registered vegetables, fruit crops, field crops, turf and ornamentals.

Its protectant action makes Mancozeb DG particularly useful in preventative spray programs where thorough coverage is required before or during periods favourable to disease development. The dry flowable formulation disperses readily in water and can also be used in compatible tank-mix programs.

Active Ingredient & Mode of Action

• Active constituent: 750 g/kg Mancozeb

• Formulation: Dry flowable fungicide

• Fungicide type: Preventative / protectant

• Mode of action: Multi-site activity

• Current CropLife classification: Group M3

• Pack size: 2kg

Mancozeb belongs to the dithiocarbamate group of multi-site fungicides. This means it acts at several sites within fungal cells rather than relying on a single biochemical target. Current CropLife Australia guidance classifies mancozeb as Group M3.

The Barmac label available online may still display the older Group Y terminology.

Mancozeb DG Fungicide Dosage

There is no single Mancozeb DG dosage for every plant or disease. Rates depend on the crop, fungal disease, spray method and conditions.

Common registered Barmac Mancozeb DG rates include:

• Many vegetables: 150–200 g per 100 L water

• Tomatoes: 150–200 g per 100 L or 2–3 kg/ha

• Potatoes: 150–200 g per 100 L or 1.7–2.2 kg/ha

• Grapevines: generally 150–200 g or 200 g per 100 L, depending on disease

• Roses for black spot: 150–200 g per 100 L

• Gladioli and chrysanthemums: 150–200 g per 100 L

• Ferns: 75–100 g per 100 L

• Turf: 200–250 g per 100 m², applied in sufficient water for coverage

Always select the rate corresponding to the specific crop and disease on the registered label.

Mancozeb Fungicide Dosage Per Litre

For applications where the Barmac Mancozeb DG label specifies 150–200 g per 100 L, the equivalent concentration is:

• 150 g per 100 L = 1.5 g per litre

• 200 g per 100 L = 2 g per litre

For ferns, the registered 75–100 g per 100 L rate equals approximately:

• 0.75–1 g per litre

These conversions only apply where the relevant crop directions specify those rates. Some uses are calculated per hectare or per 100 m² rather than per litre.

How to Use Mancozeb DG Fungicide

For correct mixing and application:

• Partly fill the spray tank with water.

• Begin agitation.

• Add the required quantity of Mancozeb DG steadily.

• Continue agitation while filling the tank.

• Maintain agitation throughout spraying to keep the mixture uniform.

• Apply thoroughly to achieve even coverage of susceptible plant surfaces.

• Clean the spray tank, pumps and nozzles after use.

For low-volume or aerial applications, the label advises preparing a slurry or premix before adding the product to the spray tank.

When to Apply Mancozeb DG

Mancozeb DG works primarily as a protectant fungicide, so timing is important.

Applications should generally begin when conditions favour disease development or at the first signs specified in the crop directions. Repeat treatments may be necessary to protect new growth.

Many registered applications use approximately 7–14 day intervals, although the correct interval varies according to crop, disease pressure and weather conditions. Higher registered rates or shorter intervals may be appropriate when conditions strongly favour fungal disease development.

Resistance Management

Mancozeb provides multi-site fungicidal activity, making it useful in resistance-management programs when used appropriately with other fungicide modes of action.

Current CropLife Australia classification places mancozeb in Group M3 – multi-site activity, dithiocarbamates and relatives.

Follow crop-specific resistance strategies and product label directions when rotating or tank mixing fungicides.
