Crop Protection in a Changing World: how PBO helps mitigate resistance risks and protect yields

Crop protection today is facing a perfect storm: warmer climates, shifting pest behavior, and increasing resistance are making infestations more aggressive and harder to control, especially in stored grain and agricultural environments where prevention is critical.

As pest populations expand and reproduce faster, those responsible for protecting crops and grain face growing challenges, including:

• Increased infestations in stored grain
• Higher risk of spoilage and quality degradation
• Greater food loss, directly threatening food security

In this increasingly volatile scenario, effective crop protection is no longer just about killing pests, it is about managing risk. 

Resistance: the core challenge behind crop losses 

One of the most critical issues in modern agriculture is insect resistance.
Many pests have developed metabolic mechanisms that allow them to survive treatments that were once effective, particularly against pyrethroid insecticides, widely used in crop and grain protection.

As resistance increases:

• Standard application rates lose effectiveness
• Treatments must be repeated
• Chemical load rises
• Control becomes less predictable

This creates a damaging cycle where more insecticide delivers diminishing results, increasing costs and environmental pressure.

The role of Piperonyl Butoxide (PBO): why it matters

Piperonyl Butoxide (PBO) is a synergist, it does not kill pests directly, but it dramatically enhances the efficacy of insecticides, making it a powerful ally in crop protection.

PBO works by inhibiting the enzymes insects use to detoxify insecticides. By blocking this natural defense mechanism, PBO ensures that insecticides remain active and effective, even against resistant populations.

This mode of action makes PBO a game‑changer in agricultural and stored grain protection.

Synergistic action: making insecticides work again

PBO blocks detoxification enzymes such as cytochrome P450s and esterases.
As a result:

• Insects can no longer neutralize the insecticide
• Active ingredients reach their target sites more effectively
• Pests become more vulnerable and easier to control

Outcome: restored efficacy, even in resistant pest populations.

Resistance management built into the formulation

By enhancing insecticide performance, PBO helps:

• Delay the development of resistance
• Overcome resistance already present in pest populations
• Maintain reliable control in challenging scenarios

This makes formulations containing PBO a more robust and future‑ready choice for crop and grain protection.

Lower dosage, higher impact

One of the most tangible advantages of PBO is efficiency.

Thanks to its synergistic effect:

• Lower concentrations of insecticides can be used
• High efficacy is maintained
• Overall chemical load is reduced

This supports both cost control and environmental responsibility, without compromising performance.

Extended and broader protection

The synergy between PBO and insecticides provides:

• Longer‑lasting protection
• Consistent control over time
• Efficacy against a broad spectrum of pests
  

• grain weevils
• flour beetles
• moths

This is especially valuable where prevention and residual activity are critical.

A versatile, cross‑sector solution

PBO is not limited to a single application area. Its effectiveness spans:

• Agriculture and crop protection
• Stored grain and food protection
• Public health and vector control

This versatility makes PBO a strategic, cross‑sector tool, capable of addressing resistance challenges wherever they arise.

From pest control to risk management

In a world where food security, sustainability, and regulatory scrutiny are tightly interconnected, PBO helps shift crop protection from reactive treatment to proactive risk mitigation.

By restoring efficacy, reducing chemical load, and supporting resistance management, PBO enables:

• More stable yields
• Lower long‑term costs
• Protection of existing active ingredients and registrations

In short, PBO helps agriculture do more with less, and do it sustainably.

Key takeaways

✔ Climate change and resistance are increasing crop protection risks
✔ PBO restores insecticide efficacy against resistant pests
✔ Lower doses can deliver higher and longer‑lasting impact
✔ Chemical load and environmental pressure are reduced
✔ Crop yields and food security are better protected

PBO transforms crop protection into a smarter, more resilient strategy.
