‘Organic Management of Postharvest Decays’ webinar planned

Washington State University (WSU) Tree Fruit Extension will hold a webinar titled “Organic Management of Postharvest Decays on March 9.

The event will take place at 8:30 am. Pacific.

Participants will learn about best management practices to fight pre- and postharvest pathogens which continue to be a major concern in organic and conventional systems.

This event is targeted towards pome fruit growers, packers, field and warehouse workers, Extension specialists, industry representatives, consultants and others interested in learning about early disease detection and best management practices in organic orchards and packinghouses to reduce the impact of postharvest rots and increase pack-out.

What

  • Work done on a newly registered fungicide for conventional warehouses will be presented.
  • Demonstration of a novel early infection detection assay.
  • Pre and postharvest rot pathogens and best management practices in organic systems (e.g. cultural and sanitation practices, efficacy of multiple organic materials, and dynamic controlled atmosphere).
  • Updated research on a novel postharvest conventional fungicide will also be presented.

Format

  • The event includes presentations, activities, quizzes and networking opportunities.
  • Seven hours of training and interactive activities.

In this workshop participants will

  • build a foundation for best management practices of major postharvest rots;
  • learn the latest research-based information for effective management;
  • learn how to optimize decay management in organic systems, i.e., choosing most effective materials and best time for sprays.

This workshop is sponsored by Washington State University Extension with support from the Washington Tree Fruit Research Commission and Syngenta Crop Protection.

Registration

Registration required. To register visit here.
