Protecting Boxwood from Boxwood Blight By Nancy Rechcigl, Syngenta Technical Services

8/4/2014 - By Harrell's

Boxwood (Buxus) species are popular landscape and garden shrubs and have been an important staple in many well-known gardens across the nation. In 2011, a severe blight known as Boxwood blight (Cylindrocladium buxicola), was identified in 2011 in the U.S. causing defoliation of Boxwood species. This disease thrives in warm and humid environments causing symptoms such as leaf spots, cankers, straw/bronze colored foliage and defoliation. The fungus enters the plant through the leaf cuticle or stomata. It survives in the environment as mycelia in plant debris, and when conditions are favorable, spores are produced spreading the disease to neighboring boxwood.
