Difenoconazole Formulations for Importers: EC, WG, SC Mixtures and Seed Treatment

Difenoconazole Formulations for Importers: EC, WG, SC Mixtures and Seed Treatment

This guide explains how professional buyers can compare difenoconazole formulations across foliar and seed-treatment segments before shortlisting suppliers. It is an educational sourcing resource, not an application recommendation, product label or legal opinion. Product approval, label directions and commercial legality must always be verified for the destination jurisdiction.

Difenoconazole is a systemic triazole fungicide classified by FRAC in Group 3 as a demethylation inhibitor (DMI). It is one of the most widely quoted DMI actives, supplied straight for foliar programmes, in strobilurin co-formulations, and as a component of seed-treatment combinations — three configurations with different procurement questions.

Straight foliar configurations

Averstar lists straight difenoconazole as Difenoconazole 25% EC and Difenoconazole 10% WG.

An EC carries the active in an organic solvent system — ask which solvent is used and whether it is acceptable under destination-market chemical rules — while a WG avoids liquid packaging and solvent questions in exchange for dissolution and moisture-protection checks. Request the safety data sheet for the exact configuration quoted and compare the hazard and storage sections directly.

Strobilurin co-formulations

The most requested difenoconazole mixtures pair the DMI with a QoI partner from FRAC Group 11. Averstar lists Azoxystrobin + Difenoconazole 200g/L / 125g/L SC and Azoxystrobin + Difenoconazole 180g/L / 120g/L SC.

Two loadings of the same pair are not interchangeable offers: reconcile both actives to one concentration basis, compare the resulting cost per treated unit, and confirm which loading the destination registration actually covers. As with any mixture, every active and the mixture itself must be acceptable in the destination market, and resistance-management positioning should be reviewed with local advisers using the current FRAC classification.

Seed-treatment combination

For the seed-treatment segment, difenoconazole appears in the triple combination Difenoconazole + Fludioxonil + Thiamethoxam 2.2% / 2.2% / 22.6% FS. Seed-treatment procurement carries its own questions — colourants, adhesion, dust-off, treating-equipment compatibility and treated-seed labelling — and should not be quoted against foliar supply of the same active.

Packaging, shipment and sample planning

EC, SC and FS offers are normally quoted in bottles, co-packs and drums; WG configurations ship in moisture-protective bags or foil packaging inside export cartons. Ask each supplier to state packaging materials, net contents per unit and the export carton configuration on the quotation before artwork is prepared.

When samples are needed for registration or laboratory verification, agree in writing what the sample represents: the batch, the formulation version and the specification revision. A sample drawn from a pilot batch does not prove that commercial shipments will match, so tie the commercial contract to the certificate of analysis of each shipped batch rather than to the sample alone.

Documents to request before shortlisting

An evidence-led comparison needs the same document set from every candidate supplier: the certificate of analysis, the proposed or registered label, the safety data sheet, the product specification, packaging details and the manufacturing-site identity. Ask for the version and date of each document, and keep the records together so that differences between a quotation, a label and a technical sheet can be resolved before commercial commitments are made.

Registration and residue references

Use the FAO pest and pesticide management resources for framework guidance and the Codex pesticide residues database for internationally referenced maximum residue limits, then confirm current national decisions with the destination authority. Nothing in this guide replaces the registered label or local regulatory advice.
