What is DAS?

The California Decision Aid System (DAS) for Navel Orangeworm is a collaborative, science-based project designed to support Integrated Pest Management (IPM) decision-making in California tree nut production. The project adapts the proven WSU Decision Aid System framework to California conditions, crops, and pest pressures, emphasizing regional coordination and preventative management of navel orangeworm (Amyelois transitella).

This effort brings together university researchers, industry organizations, and grower-facing outreach staff to deliver timely, actionable pest management guidance at the orchard- and region-scale.
