Corteva Curzate M8 Fungicide: Product Overview

Corteva Curzate M8 contains Cymoxanil 8% + Mancozeb 64% WP, a two-active fungicide registered in India for specified late blight and downy mildew uses.

The current Indian major-use table lists potato and tomato late blight, grape and cucumber downy mildew, and a separate citrus gummosis treatment. The formulation rate, water volume and application method differ by crop, so select the relevant row below and follow the current statutory pack label.

Verified Product Benefits

• Complementary fungicide groups: Cymoxanil is classified in FRAC Group U27, while mancozeb is a multi-site Group M03 fungicide.
• Crop-specific directions: The registered table provides formulation dose and water volume for each crop.
• Defined harvest interval: A 10-day PHI is listed for the four registered foliar uses shown here.
• Wettable-powder formulation: The WP formulation should be measured and mixed strictly according to the current pack directions.

Technical Specifications

How Curzate M8 Works

FRAC classifies cymoxanil as Group U27, a cyanoacetamide-oxime fungicide group whose precise biochemical mode of action is not fully defined. Mancozeb is a Group M03 multi-site fungicide that acts at several fungal processes. This page does not claim that the combination is resistance-proof.

Use Curzate M8 only for a crop-and-disease combination on the current Indian label. Follow label resistance-management limits and use any alternative fungicide only where its own label supports the crop and disease.

Registered Crops, Diseases and Label Directions

PHI means pre-harvest interval. No universal per-litre or pump dose is published because the registered directions specify dose and water volume per hectare.

Separate Registered Citrus Gummosis Treatment

This is a separate drench-and-trunk-paint direction, not a foliar per-hectare rate. Follow the current citrus label row exactly.

Application and Stewardship Guide

• Confirm the diagnosis: Use only for a registered crop-and-disease combination.
• Measure by crop: Use the formulation dose and water volume in the relevant label row.
• Mixing: Add and agitate the wettable powder exactly as directed on the current pack; no tank-mix recommendation is made here.
• Coverage: Use properly calibrated equipment and the crop-specific water volume stated on the label.
• Resistance management: Do not rely on Curzate M8 outside the label programme or assume that the mancozeb component makes every use resistance-proof.
