Presentation:
Rethinking the last spray: biopesticides for residue mitigation

Key Points:
• Late-season pesticide applications are a key factor driving residues that limit market access for horticultural exports.
• Biological plant protection products offer a practical way to reduce residues while maintaining effective pest control.
• Studies across multiple crops and locations demonstrate that replacing the final conventional spray with biopesticides can lower residues without compromising pest management.
• Continued trials and refinement of late-season strategies can support growers, strengthen compliance with international standards, and promote more sustainable crop production.
