Removing blighted trees to control the disease was first attempted when the blight was discovered, but this proved to be an ineffective solution. Scientists then set out to introduce a hyperparasitic hypovirus into the chestnut blight fungus. The trees infected with virus-treated fungus responded immediately and began to heal over their cankers.
Young tree in natural habitat American chestnut male (pollen) catkins. Castanea dentata is a rapidly-growing, large, deciduous hardwood eudicot tree. [20] A singular specimen manifest in Maine has attained a height of 115 feet (35 m) [21] Pre-blight sources give a maximum height of 100 feet (30 m) and a maximum circumference of 13 feet (4.0 m).

Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. [1] Accordingly, many diseases that primarily exhibit this symptom are called blights.
The most common mode of transmitting the blight is by the introduction of asymptomatic plants, or plants treated with fungicide (which can mask the disease) to unaffected areas. [13] Warm and humid conditions facilitate its spread. [14] The fungus does not need a wound to infect a plant, but it does require high humidity or free water. [15]
While these blight-caused blockages cause the decline of an infected tree, the plant rarely dies. [1] Co-infection between citrus blight and citrus greening disease (HLB) is possible, and is so severe a health issue that trees infected by both diseases usually die. [3] The disease affects trees of all ages and types, including seedlings and ...

Diplodia tip blight, also known as Sphaeropsis blight, is a widespread disease affecting conifers caused by an opportunistic fungal pathogen, Diplodia sapinea. It is found in “both hemispheres between the latitudes 30° and 50° north and south". [ 1 ]
