COLUMBIA, Mo. – University of Missouri Extension’s Plant Diagnostic Clinic, in partnership with the Missouri Department of Conservation (MDC), will offer free testing for all common oak tree diseases in 2024.

“With this service, we hope to collect information on the location and host species of oak diseases across the state,” says Peng Tian, director of the Plant Diagnostic Clinic on the MU campus. “We are also actively scouting for new or invasive diseases of oaks to better assist MDC and the Missouri Department of Agriculture with controlling forest pest problems.”
