Tebuconazole Formulations for Importers: Foliar and Seed-Treatment Supply

Tebuconazole Formulations for Importers: Foliar and Seed-Treatment Supply

This guide explains how professional buyers can compare tebuconazole 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.

Tebuconazole is a systemic triazole fungicide classified by FRAC in Group 3 as a demethylation inhibitor (DMI). It is one of the most widely quoted fungicide actives, supplied both for foliar programmes and as a seed treatment — two segments that run on different formulations, packaging and procurement questions, so the first step is to be explicit about which segment a request belongs to.

Foliar formulations: EW, SC and WG

For foliar supply, Averstar lists Tebuconazole 25% EW, Tebuconazole 43% SC and the high-load Tebuconazole 75% WG.

An EW (emulsion, oil in water) reduces the organic-solvent load compared with a classical EC, which changes flash-point, packaging and transport-classification questions; an SC is water-based with its own suspensibility and storage guidance; a high-load WG concentrates more active into each shipped kilogram and avoids liquid packaging entirely. Request the safety data sheet for each configuration and compare the hazard and storage sections directly rather than assuming equivalence.

Seed-treatment configurations

For the seed-treatment segment, Averstar lists Tebuconazole 2% DS, a powder for dry seed treatment, and Tebuconazole 2% FS, a flowable concentrate for seed treatment.

Seed-treatment procurement usually involves additional questions: colourant requirements so treated seed is visibly marked, adhesion and dust-off behaviour, compatibility with treating equipment, and destination rules on treated-seed labelling. Confirm these on the specification instead of treating a seed-treatment FS as interchangeable with a foliar SC of the same active.

Ready-mixed combinations

Mixtures pair tebuconazole with partners from other FRAC groups: Fluopyram + Tebuconazole 17.5% / 17.5% SC combines the DMI with an SDHI partner, and Tebuconazole Trifloxystrobin 30% SC combines it with a QoI partner. For any mixture, every active ingredient must be acceptable in the destination market and the mixture itself normally needs its own registration; resistance-management positioning should be reviewed with local advisers using the current FRAC classification.

Packaging, shipment and sample planning

Liquid configurations are normally quoted in bottles, co-packs, drums and intermediate bulk containers; WG and DS 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, and confirm that proposed retail pack sizes are acceptable under destination labelling rules 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.

For the general framework, see our fungicide mode-of-action guide for product buyers and the fungicide registration document checklist.

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.
