Key Benefits of Synergy M-45

• Broad-Spectrum Disease Management: Helps manage a range of susceptible fungal and oomycete diseases.

• Blight and Rust Management: Recommended for several blight, leaf spot and rust diseases in listed crops.
• Multiple Crop Applications: Manufacturer-listed uses include cereals, vegetables, fruits and oilseed crops.
• Preventive Disease Protection: Particularly useful before infection or during early disease development as part of an integrated disease management programme.

How Does Synergy M-45 Work?

Mancozeb is a non-systemic, multisite contact fungicide belonging to FRAC Group M03. It disrupts several enzyme-dependent processes required for normal fungal growth and metabolism.

When applied correctly, the fungicide remains primarily on treated plant surfaces and helps prevent susceptible fungal spores from germinating and establishing infection.

Unlike systemic fungicides, Mancozeb does not move extensively through plant tissues. Good spray coverage is therefore important, and it should not be expected to cure established internal infections or restore damaged plant tissue.

Recommended Crops and Target Diseases

The crop and disease information is based on Synergy's product catalogue and general Mancozeb 75% WP references. Follow the current Synergy M-45 registered label for exact approved uses.

Recommended Dosage and Application

How to Apply: Measure the crop-specific label-recommended quantity and first mix it with a small amount of clean water to form a uniform slurry. Add the mixture to the spray tank containing water, agitate thoroughly and complete the dilution as directed.

Spray uniformly over the crop surfaces requiring protection. Follow the original label for timing, repeat applications, water volume, waiting periods and protective equipment.

Dosage Note: Synergy lists 600–800 grams per acre for several specified crops. This rate should not automatically be applied to every crop or disease mentioned in its catalogue.

When Should You Use Synergy M-45?

Synergy M-45 is most relevant for preventive management of susceptible fungal diseases. Application before infection or when disease risk is developing helps protect treated plant surfaces.

It may also be included in an integrated fungicide programme where a multisite protectant is appropriate. Follow registered instructions for combining or alternating products with different modes of action.
