TR4 Biosecurity Add-on for Bananas

The TR4 Biosecurity Add-on for Bananas outlines a risk mitigation plan for minimizing the spread of the Tropical Race 4 fungus, also known as Foc TR4, – one of the most destructive diseases in banana and plantain crops – to, within, and from farms with Integrated Farm Assurance (IFA) certification.

The GLOBALG.A.P. add-on for tackling Fusarium wilt

What is the TR4 Biosecurity Add-on for Bananas?

Tropical Race 4 fungus, also known as Foc TR4, is the name given to the strain of the fungus Fusarium oxysporum f. sp. cubense. It is one of the most destructive diseases in banana and plantain crops worldwide, threatening millions of producers who rely on these crops for their subsistence. With effective treatments yet to be discovered, preventative measures are currently the only practical way of containing the disease and protecting the livelihoods of banana and plantain producers. The TR4 Biosecurity Add-on for Bananas outlines a risk mitigation plan for minimizing the spread of Foc TR4, and the add-on can be implemented and combined with Integrated Farm Assurance (IFA) for fruit and vegetables.

Who should use the TR4 Biosecurity Add-on for Bananas?

The TR4 Biosecurity Add-on for Bananas is applicable for banana and plantain farms worldwide and covers both producers who are trying to prevent the introduction of Foc TR4 and farms where the pathogen is already present.

The add-on is intended for banana or plantain producers who are already certified to IFA for fruit and vegetables. For producers who are not yet registered in the GLOBALG.A.P. certification system, the TR4 Biosecurity Standard offers the same risk mitigation plan but in a format which can be implemented independently from other GLOBALG.A.P. standards.

The add-on is available for producers of all sizes, from smallholders to large producer groups. Producers can get audited in any country where a GLOBALG.A.P. approved certification body (CB) conducts audits.

How does the TR4 Biosecurity Add-on for Bananas work?

  • Compliance with the add-on requirements is audited annually by an accredited and independent third-party CB together with the annual IFA audit (or an audit against a benchmarked scheme/checklist).

  • Producers can choose from any GLOBALG.A.P. approved CB active in the relevant country – although the same CB which conducts the IFA audit must also conduct the TR4 Biosecurity Add-on for Bananas audit.

  • A successful CB audit results in a letter of conformance valid for one year.

The add-on is composed of principles and criteria (P&Cs). P&Cs are graded in two levels: Major Must and Recommendation.

Principles

  • Fundamentals that set the foundation of a GLOBALG.A.P. requirement

  • Written in statement form

  • Describe the outcome to be achieved in the corresponding criteria

Criteria

  • Methods that producers can use to demonstrate a principle to be true

  • Compliance can be demonstrated in different ways, e.g., data, record of procedure

  • Evidence must demonstrate that the outcome is achieved

Read more about the audit process and add-on requirements.

How is conformance status verified?

Every producer registered in the GLOBALG.A.P. certification system is assigned a 13-digit GLOBALG.A.P. identification number (e.g., a GLOBALG.A.P. Number (GGN)). This number allows real-time verification of conformance status in the GLOBALG.A.P. IT systems, upholding our rigorous transparency requirements throughout the supply chain.

Producers can control data access and privacy rights for audit reports, and the reports are not shared publicly or with third parties. This process is handled via your chosen CB.

Protecting the interests of banana and plantain producers

Why choose the TR4 Biosecurity Add-on for Bananas?

The livelihoods of banana and plantain producers – and the long-term security of the sector – depend on preventing the spread of the Tropical Race 4 fungus, also known as Foc TR4. The TR4 Biosecurity Add-for Bananas provides a key tool for tackling the destructive fungus.

Which industry challenges does the TR4 Biosecurity Add-on for Bananas address?

  • The social consequences of Foc TR4 are serious: Bananas and plantains are an important source of food, employment, and income in many tropical countries. The wider spread of Foc TR4 throughout the world would affect millions of producers that rely on banana/plantain cultivation for their livelihoods.

  • Like all other soilborne Foc strains, Foc TR4 cannot be controlled using fungicides and cannot be eradicated from soil using fumigants. The optimal, economically available preventive measure is quarantine, preventing the transfer of affected land or plant material from infected to Foc TR4-free areas.

  • The capacity of Foc TR4 to survive in the soil for decades, along with its lethal impact and wide host range, are among the main reasons it was ranked as the greatest threat to banana production by the World Health Organization (WHO).

  • The TR4 Biosecurity Add-on for Bananas is a key tool for preventing the spread of the pathogen to/​within/​from banana and plantain farms and, most importantly, it helps raise awareness about the seriousness of the disease on a global scale.

  • The add-on is available to producers who have already achieved Integrated Farm Assurance (IFA) certification, offering a tool with which local phytosanitary authorities, national plant protection organizations, and other value chain stakeholders can recognize compliant producers.

Call to action to “Save the Banana”

In November 2018, GLOBALG.A.P. and the World Banana Forum (WBF) presented a global action plan to save bananas from the threat of Foc TR4 at the GLOBALG.A.P. SUMMIT in Lima, Peru.

The first step was to create a GLOBALG.A.P. add-on for banana producers which outlines a risk mitigation plan for producers who have already achieved IFA certification. This add-on then formed the basis for the stand-alone TR4 Biosecurity Standard, which was launched in July 2023.

The following signatories were the first to commit to fighting the highly dangerous pathogen:
