Factors affecting boxwood blight spread under landscape conditions1 [PDF]

Journal of Environmental Horticulture, 2021
Abstract We investigated the spread of boxwood blight in a simulated landscape under conducive natural conditions from 2017 to 2019. We used strict sanitation to greatly reduce or eliminate spread by contact. Movement of the pathogen from an infected source plant was limited to one plant, likely spread by means of water splash.
