Getting the Most Out of Trunk Injections

Date/Time: 
Jan 23 2017 - 3:00pm

The use of trunk injections by tree service companies has increased rapidly in recent years.  A variety of compounds including nutrients, insecticides, and fungicides can be effectively applied to trees via trunk injection.  Achieving rapid uptake and distribution of trunk-injected chemicals within trees, however, can be difficult.  Dr. Bert Cregg (Michigan State University, Departments of Horticulture and Forestry) will discuss how soil, tree, and weather interact to control sap flow and will provide tips to ensure optimal uptake during trunk-injection applications.
