Use of Mycelium and Detached Leaves in Bioassays for Assessing Resistance to Boxwood Blight [PDF]

Plant Disease, 2016
Boxwood blight caused by Calonectria pseudonaviculata is a newly emergent disease of boxwood (Buxus spp. L.) in the United States that causes leaf drop, stem lesions, and plant death. A rapid and reliable laboratory assay that enables screening hundreds of boxwood genotypes for resistance to boxwood blight is needed to enable breeding and selection of

Biological control of boxwood blight by Pseudomonas protegens recovered from recycling irrigation systems

Biological Control, 2018
Abstract Boxwood blight caused by Calonectria pseudonaviculata (Cps) is an emerging disease in the United States. It has caused significant loss to the ornamental nursery and landscape industries. In this study, 1547 bacterial strains recovered from recycling irrigation systems were evaluated in vitro and in planta for their biological control ...

Fungicide Efficacy Against Calonectria pseudonaviculata, Causal Agent of Boxwood Blight [PDF]

Plant Disease, 2014
Calonectria pseudonaviculata causes leaf spot and stem lesions resulting in defoliation and dieback of boxwood. Fungicides representing 20 different active ingredients from 13 different Fungicide Resistance Action Committee groups were evaluated for their effects on conidial germination and mycelial growth using in vitro assays, and the concentration ...

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.
