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. If a way can be found to help the spread here of strains of the fungus with controlling agents, it may be possible to save the American chestnut…

Chestnut blight: an epidemic checked by biological control
TLDR
The development of biocontrol techniques, based on natural recovery of diseased plants, has prevented the extinction of the European chestnut.
Chestnut blight and its biological control in the Sopron Hills, Hungary
The distribution of chestnut blight caused by Cryphonectria parasitica was surveyed in the forests of Sopron Hills. The infection rate was dif ferent in the forest subcompartments ranging up to 35%.…
BIOCONTROL OF THE CHESTNUT BLIGHT FUNGUS CRYPHONECTRIA PARASITICA
TLDR
This study explores the use of endogenous bark fungi from healthy American chestnut as potential biocontrol organisms against C parasitica, finding an antagonistic isolate of Trichoderma spp.
BACTERIA FOUND ON AMERICAN CHESTNUT BARK AND THEIR POTENTIAL IN BIOCONTROL OF CHESTNUT BLIGHT
TLDR
The study reveals that some Bacillus megaterium isolates from C. dentata bark may have potential in biological control, and provides an explanation for the success of mud packs in ‘healing’ cankers.
Chestnut blight in Yugoslavia1
TLDR
The present state of chestnut blight caused by the fungus Cryphonectria parasitica in Yugoslavia is presented and field observations have shown the presence of abnormal disease symptoms at some localities.
Developing Blight-Tolerant American Chestnut Trees.
TLDR
To help restore this important canopy tree, blight-tolerant American chestnut trees have been developed using an oxalate oxidase-encoding gene from wheat.
Biological control of chestnut blight with hypovirulence: a critical analysis.
TLDR
Overall, however, not enough is understood about the epidemiological dynamics of this system to determine the crucial factors regulating the establishment of hypovirulence in chestnut forests.
Hypovirulence in chestnut blight fungus, Cryphonectria parasitica, in Slovakia
ABSTRACT The recovery of the European chestnut from chestnut blight in Europe is attributed to hypovirulence, a viral disease that reduces the virulence of its host – Cryphonectria parasitica.…
Biological control of chestnut blight in Croatia: an interaction between host sweet chestnut, its pathogen Cryphonectria parasitica and the biocontrol agent Cryphonectria hypovirus 1.
TLDR
Some CHV1 strains belonging to the Italian subtype have similar hypovirulent effects on C. parasitica isolates, and virus-fungus-chestnut interactions could have significant implications for the success of chestnut blight biocontrol.
Chestnut gall wasp ( Dryocosmus kuriphilus ) infestations: new opportunities for the chestnut blight fungus Cryphonectria parasitica ?
The invasive chestnut gall wasp Dryocosmus kuriphilus (Cynipidae) is one of the most important insect pests on Castanea species worldwide (EPPO, 2005). In 2009, D. kuriphilus was found for the first…

Chestnut Blight: Biological Control by Transmissible Hypovirulence in Endothia parasitica
Hypovirulence in Endothia parasitica is caused by a cytoplasmic determinant that is transferred by hyphal anastomosis in host tissue and in culture. Transmission of this determinant affects the…

TLDR
The hypothesis that vegetative incompatibility serves as a cellular defence mechanism against genetic infection by stopping the spread of viruses and other suppressive cytoplasmic determinants from strain to strain in nature is supported.
Revised estimates of the molecular weights of dsRNA segments in hypovirulent strains of Endothia parasitica.
TLDR
The molecular weights of the dsRNA segments in hypovirulent strains of Endothia parasitica were estimated to be less than in European strains to avoid over-estimating the molecular weight of the large dsRNAs in E. Parasitica.

TLDR
The need for specialized texts is clear, and three new publications take substantial steps to satisfy this need, and two of the publications are in essence introductory student texts.
