An Improved Leaf Disc Bioassay for Detecting Calonectria pseudonaviculata in Soil and Potting Media [PDF]
Plant Disease, 2014 Boxwood blight caused by Calonectria pseudonaviculata results in severe defoliation and dieback to boxwood (Buxus spp.). The pathogen was first described in the United Kingdom and New Zealand in the mid to late 1990s and has since spread throughout Europe and most recently to the United States and Canada. While many Calonectria spp.

Sensitivity of Calonectria pseudonaviculata, the Pathogen of Boxwood Blight, to Strobilurin and Demethylation Inhibitor Fungicides in Connecticut1 [PDF]
Journal of Environmental Horticulture, 2017 Abstract Calonectria pseudonaviculata (Lombard, Crous, Wingfield & Wingfield) causes a severe blight disease on boxwood known as “boxwood blight”. Three isolates: 11-9-4a and CTWH1 - wild types from Connecticut landscapes, and FC1 - an isolate of 11-9-4a that was selected for ability to grow on up to 250 μg a.i./ml pyraclostrobin
