Azoxystrobin Fungicide

What Is Azoxystrobin? What Is Azoxystrobin

Azoxystrobin belongs to the strobilurin class of fungicides and is classified as a QoI (quinone outside inhibitor). Its primary target is the Qo site of the cytochrome bc1 complex in fungal mitochondria.

Compared to fungicides with different modes of action, the product positioning of azoxystrobin should be determined based on the target pathogens, crops, disease stages, and specific formulations. One cannot assume that a product is suitable for all fungal diseases solely based on the name of the active ingredient.

For purchasing clients, understanding the mode of action of azoxystrobin helps assess its compatibility with existing fungicide portfolios and facilitates compliance with resistance management requirements.

Mode of Action

Azoxystrobin inhibits the electron transport chain in the fungal mitochondria, disrupting energy production in susceptible fungi and thereby inhibiting their normal growth and related biological processes.

FRAC Group 11 — QoI Fungicide

Azoxystrobin belongs to FRAC Group 11. Fungicides in this group act on the Qo site of the mitochondrial cytochrome bc1 complex and are classified as respiratory inhibitors.

In practical crop protection applications, the efficacy of azoxystrobin depends on the susceptibility of the target pathogen, the product formulation, application conditions, and the scope of registered use.

It is important to note that a description of the mechanism of action does not constitute a guarantee of product efficacy. One cannot claim, based solely on FRAC classification, that a particular formulation has a fixed residual period, is curative against all diseases, or is capable of eliminating established lesions.

Crop Disease Applications

Azoxystrobin serves as the active ingredient in various fungicide formulations for the management of crop diseases in accordance with applicable registration requirements. Specific target crops and pathogens should be confirmed based on the actual product label.

Products with different concentrations, formulations, and active ingredient combinations may have different approved uses. Therefore, this page does not list all common crops and fungal diseases uniformly as the guaranteed scope of control for azoxystrobin products.

How to Confirm Crop and Disease Suitability

When evaluating products, buyers should focus on verifying the following information:

• Crop Registration: Whether the target crop falls within the approved scope of use for the specific product.
• Target Disease: Whether the product label explicitly lists the corresponding diseases or pathogens.
• Formulation and Concentration: Whether the actual concentration and formulation meet procurement and registration requirements.
• Application Conditions: Do the application timing, application method, and usage restrictions comply with the label?
• Residue Requirements: Maximum residue limits (MRLs) and pre-harvest intervals for the target market.

If a procurement project involves multiple countries or crop types, the registration requirements for the corresponding products should be verified separately; the scope of use in one market should not be directly applied to other markets.

For information on disease management strategies for different crops, refer to Crop Disease Management Solutions.

Formulations and Product Specifications

Azoxystrobin can be used in various types of fungicide formulations. The specific formulation, active ingredient content, and application method of a product should be determined by the label and technical specifications of the actual product supplied.

Formulation Selection Considerations

Procurement Evaluation Items	Items to Confirm
Active Ingredient Content	Active Ingredient Content and Labeling Basis
Formulation Type	Official Formulation Code and Corresponding Product Name
Physical Properties	Quality parameters corresponding to the specific formulation
Product Stability	Stability data for the corresponding product
Packaging Compatibility	Compatibility between the formulation and packaging materials
Application Method	Usage instructions as specified on the approved label
Registration Status	Registration status in target markets

Dosage forms such as SC, WG/WDG, FS, and GR have different formulations and usage requirements; they are not interchangeable, and the scope of use for a specific product cannot be inferred solely from the dosage form code.

If comparing different specifications, refer to the actual product label, Technical Data Sheet (TDS), and corresponding quality standards. For different dosage forms of the same active ingredient, do not directly apply the same application rate, method of use, or quality criteria.

Available Product Specifications

For specific available strengths, dosage forms, and packaging specifications, refer to the current POMAIS product catalog.

For procurement projects requiring fixed concentrations, specific formulations, or registration documentation for target markets, it is recommended to specify the target country, required specifications, and intended use prior to requesting a quote, in order to verify product availability and relevant technical documentation.

This page does not list unconfirmed fixed specifications, nor does it combine parameters from different formulations into a single generic product standard.

Fungicide Resistance Management

Azoxystrobin belongs to FRAC Group 11. Fungicides in this QoI group require close monitoring for resistance risks and should therefore not be used as a long-term, sole means of disease management.

Key Resistance Management Considerations

• Evaluate the product’s actual control value based on the susceptibility of the target pathogens.
• Follow applicable local FRAC guidelines and usage restrictions on the product label.
• Select fungicides that are effective against the target pathogens and have appropriately different modes of action based on specific disease management needs.
• Do not automatically consider different products within the same FRAC group as independent resistance management tools.
• Do not rely solely on increasing the number of applications or switching trade names to address resistance issues.

Resistance risks vary among different pathogens, crops, and regions. Specific application frequencies, rotation schedules, and mixing requirements should be determined based on local guidelines, product registrations, and actual control needs.

Integrating Fungicides into IPM

Integrated Pest Management (IPM) should combine field monitoring, appropriate cultural practices, management of plant debris, and other applicable non-chemical measures.

The use of azoxystrobin should be incorporated into management plans tailored to specific diseases, rather than being viewed as a one-size-fits-all solution for all crops and diseases.

Application Guidelines

The application rates and methods for azoxystrobin products depend on the specific formulation, target crop, target disease, and local registration requirements. This page does not provide application rates applicable across all products.

Application Parameters	Verification Requirements
Target Crop	Refer to the approved product label
Target Disease	Refer to the registered target pests
Application Rate	Confirm based on the corresponding product label
Application Timing	Follow the approved label
Spray Volume	Confirm based on the label and applicable application method
Application Interval	Follow label instructions
Maximum Applications	Follow label instructions
Pre-Harvest Interval (PHI)	Refer to the locally approved label
Re-Entry Interval (REI)	Refer to the locally approved label

Before purchasing or developing an application plan, verify the product identity, target crops, diseases, and locally approved uses. Do not directly apply application rates from other azoxystrobin products, nor apply label requirements from one country directly to other markets.

Safety and Regulatory Considerations Regulatory and Safety Requirements

Basic information on the active ingredient azoxystrobin is not a substitute for the safety documentation and registration data specific to a particular formulation. Formulations, concentrations, dosage forms, and label requirements may vary among different products.

Regulatory and Residue Compliance

Importers and registrants should focus on confirming the following:

• The target country’s current regulatory requirements for the active ingredient azoxystrobin and the specific formulation.
• Whether the product has the appropriate registration or legal basis for sale.
• Whether the approved label covers the target crops and pests.
• Whether the relevant MRL requirements apply to the target agricultural products.
• Whether labels, technical documentation, and import documentation comply with local regulations.

A specific formulation cannot be deemed eligible for direct entry into the target market based solely on the general use of the active ingredient or registration records from other countries.

Safe Handling and Storage

Storage, transportation, personal protection, emergency response, and waste disposal of the product must comply with the SDS, approved label, and applicable regulations for the actual product supplied.

This page does not prescribe uniform hazard classifications, fixed storage temperatures, generic shelf lives, or uniform harvest intervals. Relevant requirements should be based on specific product documentation.

Quality Control and Technical Documentation

For Azoxystrobin products, buyers should focus on verifying the active ingredient content, formulation quality, batch test results, and product traceability information.

Key Quality Checks

Quality Parameters	Key Procurement Audit Points
Product Identity	Verify active ingredient, content, and formulation
Active Ingredient Content	Confirm the labeled content and corresponding test results
Physical Properties	Verify against the quality standards for the specific formulation
