St. Louis, MO (WiredPRNews.com) Chestnut blight is one of the most destructive tree diseases ever seen. In the years between 1900 and 1940 the fungus killed almost every native chestnut tree in the United States.
The chestnut trees found in the US today are either imported varieties or hybrids created by foresters in an attempt to revive the trees. An organization called the American Chestnut Foundation is working hard to bring back the trees.
Even though the native chestnut is gone the chestnut blight which is actually an import from Asia is still around. It also affects and kills other kinds to chestnut trees.
A person can tell if the blight is affecting a chestnut tree because large rips or cankers will appear in the bark. A yellow canker can also be seen on infected trees.
Controlling the Blight
This blight spreads through spores that float through the air so it’s almost impossible to keep it out. It is possible to control its spread though.
The most effective measure is to plant trees that are not susceptible to the blight. You can learn what these are by talking to a professional arborist or tree expert. The US Forestry Service and state universities can provide useful information as well.
Other measures you can take include cutting down any infected tree and disposing of the wood from it as quickly as possible. Spraying with a good fungicide can also control the spread if you spray early enough. Two highly effective fungicides are benomyl and Bordeaux mixture both of which should be available at hardware stores and garden centers.
According to Premiere Tree Service of St. Louis, “Another good way to help trees is to make sure that any tree that looks sickly or infected gets a strong dose of a good fertilizer. This can sometimes strengthen trees and help them grow back stronger.”
