Fruit School 2015

Workshop Information

We have designed this fruit school to present the current science of physiology. We encourage participation of industry members who need a refresher and those where this is their first exposure to the topic. We hope by offering simultaneous English – Spanish translation* that a broad audience participates.
*Minimum requirement of five Spanish attendees per location for translation services to be provided. Spanish translation will not be available at the Hood River location.

The fruit school originates from Wenatchee at the CTC. The Hood River, Yakima and Richland locations will be delivered live and will allow interaction during the Q and A sessions.

Pre-registration is required. All Sessions are Sold Out!
You must designate your location and English/Spanish preference at registration.
Breaks, lunches and proceedings for both days are included in the registration fee.
