Scientists and science educators in the Wenatchee Valley have been gathering for the past few years for weekly seminars to catalyze the development of an engaged regional scientific community. Each series features the research of local scientists and invited guest speakers.

This year’s events are held at the Washington State University Tree Fruit Research and Extension Center in Wenatchee, and are open to the public. Join us for this great opportunity to learn about the incredible research in our own backyard. Prior registration is not required to attend these events.

This project is supported by a grant from Our Valley Our Future. Other supporters include: NCESD, Apple STEM Network, WSU Tree Fruit Research & Extension Center, Wenatchee Valley College, and USDA Research Station.

Sensitivity to postharvest fungicides of several Penicillium species causing blue mold of pome fruits in Pacific Northwest

Presented by Madan Pandey, Masters Student, Washington State University

The postharvest disease blue mold poses a significant threat to apples and pears in storage and represents up to 50% of total postharvest decays in the Pacific Northwest (PNW). Although the primary causal species for blue mold is believed to be Penicillium expansum, several other Penicillium species have been identified and estimated to make up to 25% of the Penicillium population in the PNW. Four postharvest fungicides are registered for the control of blue mold and other postharvest diseases. Frequent use of the same fungicides has led to the emergence of P. expansum resistant strains. If found tolerant to the four postharvest fungicides on fruit, these Penicillium species may cause a serious risk and a challenge for blue mold management in this already challenging disease but will also provide clues for better control

The seminar presentations are intended for a ‘science-based’ audience, including researchers, postdoctoral scientists, teachers, graduate students, undergraduate scientists, and science enthusiasts.

K-12 educators are also encouraged to attend the seminar series to learn about local career connections and research efforts that they can bring back to their students. Clock hours are available through the North Central Educational Service District for attending the series.
