“…Thus, regions with Mediterranean climates will likely be at higher risk of establishment if boxwood is irrigated during periods of optimal temperatures for Cps development, or during relatively wet years. Overhead irrigation in particular facilitates boxwood blight outbreaks because it creates higher relative humidity and exposes leaf surfaces to longer periods of wetness [ 19 , 120 , 122 ]. Locations that are climatically marginal for Cps , but which have extensive boxwood plantings, may be best able to exclude or eradicate boxwood blight outbreaks by implementing best practices such as using less dense plantings, limiting shade cover, and exclusively make use of underground irrigation [ 8 , 112 , 123 ].…”

Boxwood blight caused by Cps is an emerging disease that has had devastating impacts on Buxus spp. in the horticultural sector, landscapes, and native ecosystems. In this study, we produced a process-based climatic suitability model in the CLIMEX program and combined outputs of four different correlative modeling algorithms to generate an ensemble correlative model. All models were fit and validated using a presence record dataset comprised of Cps detections across its entire known invaded range. Evaluations of model performance provided validation of good model fit for all models. A consensus map of CLIMEX and ensemble correlative model predictions indicated that not-yet-invaded areas in eastern and southern Europe and in the southeastern, midwestern, and Pacific coast regions of North America are climatically suitable for Cps establishment. Most regions of the world where Buxus and its congeners are native are also at risk of establishment. These findings provide the first insights into Cps global invasion threat, suggesting that this invasive pathogen has the potential to significantly expand its range.

“…In contrast to the widespread global distribution of Cps, Che is presently detected only in six European countries: Belgium, the Czech Republic, Germany, the Netherlands, Slovenia, and the United Kingdom (Bartíková et al 2020a(Bartíková et al , 2020bLeBlanc et al 2019) (Fig. 7).…”

Boxwood blight, caused by Calonectria henricotiae and C. pseudonaviculata, is an extremely destructive disease of cultivated and native Buxus species (boxwood) worldwide. The disease is widespread in North America, Europe, and Southwest Asia. Early and accurate diagnosis of boxwood blight is the most effective tool used to prevent spread of the disease, and it is the first step for development and implementation of appropriate control measures. This diagnostic guide provides up-to-date information on how to diagnose and identify boxwood blight and also offers an overview of methods used to isolate the pathogen, store cultures, and evaluate pathogenicity of the causal agents.

“…The only reports of the pathogen from these regions have come from nurseries and gardens in the Czech Republic (Safránková et al 2012, Bartíková et al 2020a) and a single nursery in western Ukraine (Matsiakh 2016). The common element of diseased boxwood in gardens in the Czech Republic was the use of irrigation systems or partial-shade conditions, which created higher humidity and exposed leaves longer periods of wetness (Bartíková et al 2020a). Implementing the summer irrigation option in CLIMEX increased suitability throughout central and eastern Europe and resulted in an expansion of the potential distribution in western Russia, Ukraine, Turkey and the Caucasus, which provides additional evidence that irrigation will likely increase the risk of establishment of Cps in these regions.…”

Boxwood blight, caused by the ascomycete fungi Calonectria pseudonaviculata and C. henricotiae, is an emerging plant disease of boxwood (Buxus spp.) that has had devastating impacts on the health and productivity of boxwood in both the horticultural sector and native ecosystems. In this study, we predicted the potential distribution of C. pseudonaviculata at regional and global scales and explored how climatic factors shape its known range limits. Our workflow combined multiple modeling algorithms to enhance the reliability and robustness of predictions. We produced a process-based climatic suitability model in the CLIMEX program and combined outputs of six different correlative modeling algorithms to generate an ensemble correlative model. All models were fit and validated using an occurrence record dataset (N = 292 records from 24 countries) comprised of positive detections of C. pseudonaviculata from across its entire known invaded range. Evaluations of model performance provided validation of good model fit for all models. A consensus map of CLIMEX and ensemble correlative model predictions indicated that not-yet-invaded areas in eastern and southern Europe and in the southeastern, midwestern, and Pacific coast regions of North America are climatically suitable for establishment. Most regions of the world where Buxus and its congeners are native are also at risk of establishment, which suggests that C. pseudonaviculata should be able to significantly expand its range globally if susceptible hosts exist. Our findings provide the first insight into the global invasion threat of boxwood blight, and are valuable to stakeholders who need to know where to focus surveillance efforts for early detection and rapid response measures to prevent or slow the spread of the disease.
