Wiman Lab: Current research includes IPM for new and old hazelnut pests, hazelnut nutrition, hazelnut water use/irrigation, and cider apple production. Primary interests are population biology of insects, biological control, sustainable orcharding and grower outreach.
Fruit and Ornamental Disease Management Testing Program: The primary purpose of the fruit and ornamental disease management testing program is to provide Oregon growers, Extension Faculty, and Field Representatives with unbiased information on the relative efficacy of fungicides, fungicide schedules or cultural practices for control of plant diseases. Their objective is to broaden the scope of methods used to reduce crop loss due to diseases and to service the diverse management practices of Oregon growers.
