Lunch & Learn | Forest Pathology—Diseases in Washington State and their Management

September 16, 2020 @ 11:00 am - 12:00 pm

Forest Pathology—Diseases in Washington State and their Management Presented by Bob Edmonds. Forest diseases, mostly caused by fungi, are important components of natural forest ecosystems in Washington, causing tree mortality, producing snags and creating habitats for plants and animals, influencing forest succession, and recycling carbon and nutrients. Forest pathogens, fires and insects commonly act together. However, in managed forests they influence forest health, cause site degradation, kill planted trees, and cause economic losses. I will briefly describe the main diseases…

Lunch & Learn | Controlling latent infections of black dot with early fungicide applications / Using all the tools in the Fusarium management toolbox

October 21, 2020 @ 11:00 am - 12:00 pm

Controlling latent infections of black dot with early fungicide applications Presented by Lydia Tymon. Colletotrichum coccodes causes black dot, which can lead to reduced tuber yield and quality. Although this disease has been studied for many years, black dot continues to be a challenge to manage because the fungus can infect its hosts without causing symptoms. Chemical management tactics such as fumigation and in furrow applications have been shown to be ineffective. Applications of azoxystrobin prior to infection can significantly…

Lunch & Learn | Predicting and managing the impacts of invasive insects

November 4, 2020 @ 11:00 am - 12:00 pm

Predicting and managing the impacts of invasive insects Presented by Patrick Tobin. Expansion of global trade and trade has facilitated the arrival and subsequent establishment of nonnative insects. Forest ecosystems are especially threatened by non-native insects due to the worldwide importance of solid wood packaging material used in global trade, the importation of lumber and wood products, and the importation of live trees for planting, all of which provide a mechanism on which an insect can 'hitchhike.' Fortunately, of the…
