Biological Control of Chestnut Blight

Science, 1982
After 77 years of being attacked by the chestnut blight fungus, American chestnut trees continue to sprout from gradually declining root systems. The blight fungus in Italy is now associated with virus-like agents that limit its pathogenicity, and attempts have been made to introduce these controlling agents into the blight fungus in the United States.

BIOLOGICAL CONTROL OF CHESTNUT BLIGHT IN EUROPE

Annual Review of Phytopathology, 1994
Cryphonectria parasitica (MUff.) Barr. (Syn. Endothia parasitica (MUff.) And, & And.), the causal agent of chestnut blight, is a fungal pathogen of Castanea and Quercus species. After its introduction at the beginning of this century. C. parasitica virtually eliminated C. dentata Borlch. as an important forest tree species in the eastern United States.

Chestnut blight and recovering American chestnut trees in Michigan

Canadian Journal of Botany, 1983
Stands of American chestnut trees have survived in Michigan in spite of the presence of Endothia parasitica. Cankered trees were evaluated in eight groves in seven of which two types of abnormal cankers were observed. These abnormal cankers resulted when diseased periderm was replaced by wound periderm.

Measuring resistance of chestnut trees to chestnut blight

Canadian Journal of Forest Research, 1992
Four species of chestnut trees and four kinds of hybrids were inoculated with two virulent strains of the chestnut blight fungus (Cryphonectriaparasitica (Murr.) Barr). Rate of canker expansion was measured over 114 days (June–September), and rate change was used as a quantitative assessment of individual tree resistance.

Chestnut blight in Croatia and Slovenia

2011
Cryphonectria parasitica, the filamentous ascomycete responsible for chestnut blight, has been devastating chestnut trees in Croatia and Slovenia for sixty years. In order to improve knowledge of its diversity, 338 isolates of the fungus from ten Croatian populations and 254 isolates from eleven Slovenian populations were sampled.

Aerial photographs reveal chestnut‐blight foci

European Journal of Forest Pathology, 1994
AbstractInfrared photographs of a chestnut (Castanea sativa) stand of northern Switzerland which was severely infested by Cryphonectria parasitica were evaluated to document disease progress. Two original infection foci were identified in the photographs.

BIOCONTROL OF CHESTNUT BLIGHT: (IN)STABLE INFECTION OF THE CHESTNUT BLIGHT FUNGUS BY CRYPHONECTRIA HYPOVIRUS 1

2017
Backgrounds Chestnut blight is a disease caused by the plant pathogenic fungus Cryphonectria parasitica, which induces bark lesions (cankers) on stems and branches of chestnut (Castanea) species. The pathogen is successfully controlled by a double-stranded RNA mycovirus Cryphonectria hypovirus 1 (CHV1), which reduces virulence and reproductive ...
