We compiled and evaluated data from six studies to produce a list of cultivars sorted by their tolerance to boxwood blight. Comparisons of these results with those of multiple other disease resistance assays indicated that results of these studies were often inconsistent regarding which cultivars were most tolerant. National Arboretum were screened for tolerance using a lab-based detached leaf assay. Hundreds of boxwood accessions from the National Boxwood Collection at the U.S. While the disease can be mitigated somewhat through cultural practices and fungicides, the most sustainable long-term solution is the development of disease tolerant boxwood cultivars. Boxwood plants grown in temperate zones worldwide are now threatened by a destructive blight disease caused by the ascomycete fungi Calonectria pseudonaviculata and C. spp., Buxaceae) are popular woody landscape shrubs grown for their diverse forms and broad-leaved evergreen foliage, with an estimated $126 million economic impact in the U.S. Results will enable further development of consistent and accurate resistance screening protocols and indicate the most suitable material for developing more resistant cultivars. ARS Scientists in Beltsville, MD compiled and evaluated data from several studies to produce a list of cultivars sorted by their tolerance to boxwood blight. Multiple studies have been conducted to screen for resistance among cultivars however, the results of these studies are sometimes inconsistent as to which cultivars are the most disease tolerant. One of the best ways to combat this pathogen is to develop resistant cultivars. However, boxwood plants are threatened by boxwood blight, a destructive disease cause by a fungal pathogen that leads to defoliation and plant death in nurseries and established landscapes. Interpretive Summary: Boxwood is a valuable nursery commodity, with more than 11 million plants sold in the United States each year at a market value of $126 million. Ranking resistance of Buxus cultivars to boxwood blight – an integrated analysis. Submitted to: Journal of Environmental HorticultureĬitation: Kramer, M.H., Guo, H., Pooler, M.R.
