In the last few years, beginning around 2022, several states began seeing wilt and dieback on some nursery stock, specifically on redbud, maple, and dogwoods. Early symptoms included leaf chlorosis, scorched leaf margins, and wilting of current year's growth that would eventually lead to the death of individual branches and even progression into the main stem. While the 3 types of trees listed previously are still the most common hosts, this disease has been detected in a variety of woody ornamentals (see link for a complete list).

With this threat to the nursery industry and the landscape, the Tennessee Department of Agriculture spearheaded a multi-state survey for this disease. Our office participated in 2023 and 2024. A nursery inspector conducted the survey in 7 sites across the state and sent samples to Tennessee for analysis.

In 2023, we did not detect this disease in Kentucky. In 2024, from the 7 samples collected, 3 were positive: a redbud in a state park, a maple in a retail box store, and a redbud in a nursery.

Year	Number of Sites (number per county shown on map)	Number of Samples	Map
2024	7	7       (3 positive)
2023	7	7 (0 positive)
