  Without entering into the discussion as to the relation of the bark disease to coppiced areas, I will merely state that coppiced chestnut is in general apt to be affected with disease of some sort. Especially frequent are heart-rotting fungi which may enter by way of the decaying parent stump, and the unsound condition of the trunk they cause. The chestnut is the most useful tree in the world. There are 4 major species – American Chestnut (Castanea dentata), European Chestnut (C. sativa), Chinese Chestnut (C. mollissima) and Japanese Chestnut (C. crenata) and 9 less important species of the genus Castanea in the world. The chestnut blight was accidentally introduced to North America around when Chryphonectria parasitica was introduced into the United States from Japanese nursery stock. Commonly known as the Chestnut blight, it was first found in the chestnut trees on the grounds of the New York Zoological Garden (the "Bronx Zoo") by Herman W. Merkel, a forester at the Zoo.

In the s, Chinese and Japanese chestnuts were imported to the United States with the intention of utilizing them as orchard The immunity of the Japanese chestnut to the bark disease book due to their small, compact size compared to the towering American : Fagaceae.

Japanese chestnut is a chestnut species which is native to Japan and South Korea. It is a deciduous broadleaf tree having diffuse porous wood.

The wood dried easily but becomes warped and also decays fast under poor conditions. The wood is appreciated for the decorative values. Japanese chestnuts are wide spreading and Name: Korean castanea, Korean chestnut, Kuri.

Having lived side-by-side with their animals for centuries, Europeans had developed partial immunity to zoonoses such as The immunity of the Japanese chestnut to the bark disease book native Americans had no immunity and were decimated by the new diseases.

The story of the native American tribes is strikingly similar to that of the American chestnut (Castanea dentata). The chestnut was a common species in the deciduous forests of the upland. Chestnut blight, or chestnut bark disease, is caused by an introduced fungus, Cryphonectria parasitica (Murrill) Barr, (formerly Endothia parasitica [Murrill] Anderson & Anderson).

The fungus enters wounds, grows in and under the bark (Fig. 1), and eventually kills the cambium all the way around the twig, branch, or trunk (33). Japanese chestnut is resistant, but not immune, to chestnut blight (Endothia parasitica) which is a fatal fungal bark disease.

THE PATHOGENS AND PESTS OF CHESTNUTS there were over acres of chestnut trees near Philadelphia grafted with European and Japanese varieties, and that the Lovett Co., in Little Silver, New Jersey (near the coast, about 15 miles south of Long Island) had also imported Japanese chestnut trees and was selling them by mail-order (Powell, ).Cited by: Unlike its related Chinese and Japanese chestnut trees, the American chestnut lacked immunity to the Asian invader and antibiosis ensued.

The devastation began with little fanfare; blight was first discovered almost thirty years later on chestnut trees growing in the New York Zoological Garden by Herman Merkel, the chief forester. Overview. Cryphonectria parasitica is a parasitic fungus of chestnut trees.

This disease came to be known as chestnut lly found in South East Asia, accidental introductions led to invasive populations of C. parasitica in North America and Europe. The fungal disease has had a devastating economic and social impact on communities in the eastern United : Cryphonectriaceae.

European chestnut (C. sativa) was also susceptible, but was protected by the naturally spreading fungal virus. Chinese chestnut (ima) and Japanese chestnut (C. crenata) both have some resistance — but not immunity — to the disease, and have contributed their genes to resistant varieties.

Collosal, in fact, is a hybrid of European. Diseases, other than chestnut blight, have not played a major role in terms of chestnut tree growth and survival in Michigan. Chestnut blight is a very serious pathogen that needs to be taken seriously because it can infect and kill European X Japanese hybrids.

Native Americans may have used a tisane of chestnut leaves to treat severe coughs and heart disease, a poultice of the leaves for sores and a decoction of the bark to treat worms.

Family: Valsaceae Identification: The fungus that attacks the American chestnut has the appearance of a large canker, and is typically found on the tree trunk or other tree surface area. It enters tree wounds and cracks and grows in and under the bark, killing the area around the tree twig, branch or trunk.

It's important to realize, though, that Chinese chestnut trees vary considerably in blight resistance. Some individuals are quite susceptible while others are essentially immune to the disease.[4] Japanese chestnut is also comparatively resistant to blight, with European chestnut somewhat less so.

The Oriental chestnut trees have become practically immune to it, however, and it does not destroy them, but merely blemishes their bark here and there with canker spots. No one knows just how the disease found its way to the United States, but it presumably came on lumber brought from the Orient.

Contraindications: Echinacea is not recommended for continuous use as a tonic during the cold and flu season. Instead, use immune tonics, like the ones outlined in this article. Use caution when ingesting the fresh juice or tincture, as it can irritate the throat to the point of decreased airflow.

Resistant species, particularly Japanese chestnut, Chinese chestnut, Seguin’s chestnut, and Henry’s chestnut, are being hybridized with American chestnut to create new disease-resistant species. Chinese chestnuts vary considerably in their resistance to blight; some individuals are susceptible, while others are essentially immune to the disease.

• Hypovirulence gives chestnut trees a much less potent form of the disease and gives chestnuts a fighting chance for survival (i.e., fungus is restricted to the outer bark). • Once introduced into a few trees, hopes are that hypovirulence will spread throughout the forest, offering hope to surrounding trees as well.

The imported Japanese chestnut trees were infected by a bark fungus (Cryphonectria parasitica). This fungus, aka “chestnut blight,” was native to Asia where it had co-evolved alongside native Asian chestnut species. Thus, Japanese chestnuts and Chinese chestnuts (Castanea mollissima) could survive despite being infected by the fungus.

Chinese chestnuts have evolved over a long period of time in coexistence with the bark fungal disease chestnut blight (Cryphonectria parasitica, formerly Endothia parasitica), and have evolved a very successful resistance to the blight, probably more so than any other species of chestnut, so that, although it is not immune, it typically.

Resistant species, particularly Japanese chestnut, Chinese chestnut, Seguin’s chestnut, and Henry’s chestnut, are being hybridized with American chestnut to create new disease-resistant species. Chinese chestnuts vary considerably in their resistance to blight; some individuals are susceptible, while others are essentially immune to the.

Ca. asiaticus is a bacterial pathogen originating in Asia that has recently been introduced into the Americas (1). It causes citrus greening, which now presents an unprecedented threat to citrus production worldwide.
