Overview

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.

Fitness costs of fungicide resistance in Penicillium expansum

Presented by Jonathan Puglisi, PhD Student, Washington State University

Penicillium expansum is the primary causal agent of blue mold, the most important postharvest decay of apple and pear in the pacific northwest (PNW) and worldwide. Blue mold is managed most effectively through through sanitation and use of fungicides at harvest. Repetitive use of fungicides with the same mode of action has resulted in the evolution of resistance to one or multiple fungicides simultaneously in packinghouse populations of P. expansum in the PNW. There is limited research on the relationship between fungicide resistance and fitness in P. expansum, especially in regards to fungal isolates with resistance to multiple fungicides. Understanding this relationship may enable packers to better evaluate the risks posed by resistant populations of P. expansum and make informed decisions on fungicide application at harvest.

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.
