California’s tree nut industry is poised for a major leap forward thanks to American Pistachio Growers (APG). Partnering with leading research institutions and industry collaborators, APG has secured a $1 million grant from the California Department of Food and Agriculture (CDFA) under its Biologically Integrated Farming Systems (BIFS) program.

Tackling Navel Orangeworm with Data-Driven Tools

The grant funds an ambitious project designed to combat navel orangeworm (NOW), a persistent pest that affects pistachios, almonds, and walnuts. At the heart of the initiative is a new Decision Aid System (DAS), which integrates regional monitoring and weather data to forecast pest activity, optimize treatment timing, and improve communication among growers.

“This project marks a turning point for growers,” said Joe Coelho, APG Director of Sustainability. “Using real-time regional data, we can reduce pesticide use, lower costs, and enhance the quality of our crops—benefiting the entire tree nut community.”

Why This Matters for Growers

The program is expected to deliver key benefits for California growers:

• Targeted Pest Control: Reduce chemical use while maintaining strong crop protection

• Higher Nut Quality: Better timing reduces aflatoxin risk and improves harvest quality

• Stronger Regional Collaboration: Growers can share strategies and coordinate efforts across farms

• Sustainability Focused: Supports California’s ongoing push for responsible pest management

Launching in 2026

The project will kick off in early 2026 in West Fresno County and Modesto, with APG coordinating grower participation. Researchers from UC Riverside and UC IPM will lead technical efforts, ensuring the system is practical, actionable, and ready for real-world farming conditions.

A Step Toward Smarter Farming

By combining regional coordination with cutting-edge analytics, this initiative represents a new era in integrated pest management for California’s tree nut industry. Growers can expect more sustainable practices, improved crop outcomes, and reduced operational costs—cementing APG’s role as a leader in innovation for pistachios and beyond.
