Mode of Action

Prochloraz 267 g/L + Tebuconazole 133 g/L EW contains two DMI-class fungicides. Understanding their combined mode of action helps purchasers assess the product’s technical positioning and determine its suitability within the target market’s existing fungicide portfolio.

Prochloraz — FRAC Group 3

Prochloraz is an imidazole fungicide classified under FRAC Group 3, namely DMI (Demethylation Inhibitors).

Its primary function is to inhibit CYP51 (sterol 14α-demethylase)-related reactions during fungal sterol biosynthesis, thereby disrupting normal cell membrane formation and fungal growth.

The actual control efficacy of Prochloraz depends on the susceptibility of the target pathogens, the product formulation, and the specific conditions of use. One cannot assume, based solely on its mode of action, that this mixed formulation will work against all fungal diseases or eliminate lesions that have already formed.

Tebuconazole — FRAC Group 3

Tebuconazole belongs to the triazole class of fungicides and is also classified under FRAC Group 3.

It interferes with cell membrane formation in susceptible fungi by inhibiting CYP51-related sterol biosynthesis. Its performance depends on the target pathogen, timing of application, product quality, and registered conditions of use.

Although Prochloraz and Tebuconazole belong to different chemical subclasses, both act on the same primary biochemical target category. Therefore, they cannot be described as having two entirely independent resistance mechanisms.

What Does the Combination Mean for Buyers?

This combination product combines two DMI active ingredients in a single formulation; however, its actual commercial value must be assessed in the context of the target pathogens and specific product data.

Purchasers should focus on confirming the following:

• Whether both active ingredients demonstrate actual efficacy against the target pathogens.
• Whether DMI resistance is an issue amongst pathogen populations in the target market.
• Whether the product holds registration authorisation for the relevant crops and diseases.
• Whether there is data on the efficacy, stability and quality of this specific formulation to support the relevant performance claims.

Formulated products should not be deemed to have synergistic effects or a broader spectrum of control solely based on the number of active ingredients. Such conclusions must be supported by appropriate product-level trials or reliable technical data.

EW Formulation Characteristics

EW (Emulsion, oil-in-water) is an emulsion formulation in which the oil phase is dispersed as droplets within a continuous aqueous phase.

Compared with other dosage forms, the actual physical properties of EW depend on the formulation composition, emulsification system, droplet characteristics and production quality. One cannot conclude, based solely on the designation ‘EW’, that a particular product possesses better resistance to rain wash-off, leaf adhesion or field efficacy.

Formulation Quality Considerations

Quality Parameters	Key points for procurement review
Emulsion Stability	Verify the emulsion stability parameters of the actual product
Dilution Stability	Confirm stability after dilution based on the relevant product documentation
Active Ingredient Content	Confirm the content and test results for both active ingredients
Physical Appearance	Subject to the actual product specifications and quality standards
Packaging Compatibility	Verify the compatibility between the formulation and packaging materials
Storage Stability	Subject to the stability data for the relevant product
Batch Consistency	Confirm that batch quality complies with the actual product standards

Application and Handling

Product preparation, application and equipment cleaning should comply with the requirements set out in the relevant label and safety documentation.

If the purchaser needs to verify the product’s dilution stability, mixing compatibility, or rainwash resistance, they should request the relevant technical documentation rather than relying on the EW formulation’s general characteristics to make a judgement.

Target Crops and Disease Applications

How to Confirm Crop and Disease Suitability

Before evaluating the product, purchasers should verify the following information:

• Crop Registration: Whether the target crop falls within the product’s approved scope of use.
• Target Disease: Whether the registered label explicitly lists the corresponding diseases or pathogens.
• Pathogen Sensitivity: Whether the target pathogen’s sensitivity to DMI-class fungicides meets the control requirements.
• Application Conditions: Specific application timing, methods, and restrictions.
• Residue Requirements: Maximum residue limits (MRLs) and pre-harvest intervals for the target market.

Application Guidelines

Application Parameters

Project	Validation Requirements
Target Crop	Subject to the actual registered label
Target Disease	As specified in the approved list of target pests
Application Rate	To be confirmed in accordance with the relevant product label
Application Timing	To be confirmed in accordance with the approved label and actual disease management requirements
Spray Volume	To be confirmed in accordance with the label and applicable application method
Application Interval	To be carried out in accordance with label instructions
Maximum Applications	To be carried out in accordance with label instructions
Pre-Harvest Interval (PHI)	Subject to the locally approved label
Re-Entry Interval (REI)	Subject to the locally approved label

Practical Application Considerations

Product use must be based on clearly defined registered uses, target pathogens and the approved label.

Without specific product data, it is not possible to uniformly specify preventive application timings, post-symptom application regimes, fixed application intervals, or rainfast periods.

Importers and registration companies should first confirm the target country, crop, disease and intended method of use, before cross-referencing the relevant product data.

Fungicide Resistance Management

Both prochloraz and tebuconazole belong to FRAC Group 3. This combination of two active ingredients cannot replace appropriate rotation between groups with different modes of action, nor can it guarantee continued efficacy against pathogens that have already developed resistance to DMIs.

Key Resistance Considerations

• Both active ingredients share the same primary mode-of-action classification: FRAC Group 3.
• Different active ingredients within the same FRAC group cannot automatically be regarded as independent tools for resistance management.
• The target pathogens’ actual susceptibility is a key factor in assessing a formulated product’s control value.
• Select rotation products that are effective against the target pathogens, locally registered, and have sufficiently different modes of action.
• Follow product labels and applicable FRAC guidelines for specific application frequencies, rotation schedules, and other resistance management measures.

Integrating Fungicides into IPM

Resistance management should not rely solely on changing fungicides. Depending on actual crop and disease conditions, it should also include field monitoring, sound crop management practices, disposal of diseased plant debris, appropriate variety selection, and other non-chemical management measures.

For diseases where DMI resistance is a risk, develop a product rotation plan based on local monitoring results and applicable guidance, rather than assuming a particular combination will be effective simply because the FRAC numbers differ.

Regulatory and Safety Considerations

Verify product registration, sale, import, and use requirements separately for each target market. For products containing Prochloraz, pay particular attention to the active substance’s approval status in the European Union and the specific registration requirements of other countries.

Prochloraz Regulatory Status

Under Commission Implementing Regulation (EU) 2021/1450, the European Union set the expiry date for the approval of the active substance Prochloraz as 31 December 2021. Applications for renewal will no longer be supported.

Consequently, this product should not be promoted as a plant protection product currently authorised for routine use in the European Union.

For markets outside the EU, the current regulatory status of Prochloraz and Tebuconazole, specific registration requirements for the formulated product, import restrictions and applicable MRLs should be verified on a case-by-case basis. Regulatory conclusions from one market cannot be directly applied to other countries.

Market Registration and Residue Compliance

Prior to procurement, it is recommended to verify the following points individually:

• Whether the target country permits the sale and use of the relevant active substances and specific formulations.
• Whether the mixture has an applicable registration or legal basis for sale.
• Whether the approved label covers the target crops, diseases and application methods.
• Whether applicable MRL requirements apply to the target agricultural products.
• Whether the label, technical documentation and import documentation comply with local regulations.

A product must not be deemed to meet the target market’s regulatory requirements solely on the basis of the active ingredient’s technical characteristics, its historical usage record, or the supplier’s general quality assurances.

Safe Handling and Storage

Product handling, storage, transport and emergency response procedures must comply with the SDS, approved label and applicable regulations for the actual product supplied.

Requirements regarding personal protective equipment, storage conditions, re-entry intervals and waste disposal must be implemented in accordance with the specific product’s hazard classification and local regulations.
