This session will focus on insect pests and diseases that impact the health of landscape and native conifers in our region, including rusts, twig and needle blights, needle casts, scales, adelgids, bark beetles, and moths. We will examine samples in the classroom and the field. Plant Health Care (PHC) approaches to management, including acceptable Integrated Pest Management (IPM) methods will be covered. We will do diagnosis practice both in the field and lab. Bring in those samples of plant problems that have you stumped!

This series will introduce you to plant diseases and insect pests of the Pacific Northwest when they are at their peak or most easily detected. We will look at some common and familiar species as well as some new and unusual pests you need to know. Plant specimen samples will be reviewed indoors in addition to diagnosing pest problems in the field. Least toxic and most sustainable pest management methods will be emphasized. Great diagnostic resources will be discussed and utilized. Students are encouraged to bring pest and disease samples to class for discussion and diagnosis.

Lunch included in the price of registration.

Cost: $125
