Tree Fruit IPM Outreach Specialist

Julianna K. Wilson Website


A Michigan native, Dr. Wilson has over 15 years of research and outreach/extension experience in a variety of fruit and vegetable cropping systems. As the Tree Fruit Integrator / Outreach Specialist she collaborates regionally and nationally with research and extension professionals to develop sustainable solutions for producing tree fruit in Michigan. The goal of these collaborations is to continue to improve and develop farm management practices that will result in healthy, marketable tree fruit, based on what we know or have yet to learn about ecological processes.

Current assignment: Research 25% | Extension 75%

Program Description


The main goal of Dr. Wilson’s research program is to facilitate the development and implementation of tree fruit production practices that support the economic and environmental sustainability of the Michigan tree fruit industry, with a focus on managing dynamic pest and disease complexes in changing production systems. Current projects include a USDA SCRI CAP project to develop IPM practices for managing the brown marmorated stink bug (BMSB) in apple, several coordinated projects funded by a variety of sources to develop IPM strategies for managing spotted wing drosophila (SWD) in cherry, a USDA SCRI CAP project to develop integrated crop pollination practices for tree fruit, and a USDA NIFA CARE project to determine what impact fungicide use during orchard bloom may have on honey bees stocked for pollination.


The main goal of Dr. Wilson’s extension program is to produce educational materials, tools, and programs that support the needs of Michigan tree fruit growers. Dr. Wilson coordinates two invasive species statewide monitoring networks, one for spotted wing drosophila (SWD) and the other for brown marmorated stink bug (BMSB), writing regular seasonal reports posted on MSU Extension News. She is responsible for soliciting Citizen Science reports on BMSB in homes across Michigan to help determine how widespread BMSB has become in the state. She is one of the education coordinators for Great Lakes Fruit, Vegetable, and Farm Market EXPO (attended by more than 4000 people each year) responsible for the poster session and co-organizer of the Tree Fruit Session (attended by more than 250 growers in 2016). She is also a co-organizer and co-founder of MSU Bee-Palooza, a 1-day public outreach event held during National Pollinator Week in June of each year that attracts more than 400 visitors of all ages interested in learning about bees. She is regularly invited to give extension talks on a variety of topics related to tree fruit IPM and to bee conservation in general, reaching more than 2,000 people in 2016. She is an editor and contributor to the Michigan Fruit Management Guide (MSU Bulletin E-154) and a co-author on a number of pest management and pollinator-related fact sheets and bulletins. She is currently working on a new set of fact sheets that will be published as Stone Fruit IPM for Beginners and a pocket guide for identifying Apple Maturity & Storage Disorders.
