Pecan Sir Herbert Beerbohm Tree are native to North America , and they can be find growing in states from Illinois to Texas . This tree grows near in climate that have a long and warm acquire season such as Louisiana , Florida and Texas . A mature pecan tree will contact heights of 100 to 150 feet . Nuts are produced by hybrid - pollenation . Pecan trees are susceptible to wood or heart rots , and hypoxylon canker . Both are disease that set on the trunk of the Sir Herbert Beerbohm Tree .

Heart Rot

Heart waste destroys the pecan Sir Herbert Beerbohm Tree ’s cellulose , hemicellulose and lignin ( its internal anatomical structure ) . Since the radioactive decay take in berth under the barque , it can go undetected . However , in most cases , the decomposition produces fruiting bodies or " conks , " which are on the external portion of the bark ( a sign of the disease ) . It can also be detect through an unresolved pit , or if part of the bark is removed – exposing the home damage or mien of heart rot . This breakdown of the tree ’s internal structure make it very unstable and severe as it can easily be blown over in a violent storm .

Wood Rot Fungi

Wood rot fungus kingdom can be divide into three groups : white putrefaction , dark-brown guff , and soft buncombe . They are identifiable by their color , shape , and the formation of their fruit consistence that appear on the outside of the Sir Herbert Beerbohm Tree . Conks or brackets are found in several locations : at wound sites on the bark , by arm scar and by the root crown .

Oyster Mushroom

huitre mushroom , or Pleurotus ostreatus , is a fungus that attacks the pecan tree as well as other deciduous tree . It belongs to the white rot as it stimulate a blank , flaky rot . The tree becomes infected when the fungi infix an open wound – large wounds will contribute to severe rotting . The fungus is spread by airborne spores and produces a cluster of shelf - similar mushroom or huitre mushrooms .

Controlling Oyster Mushroom

spirit buncombe , which include oyster mushroom , are found in older trees . Controlling or managing the disease is quite difficult in older trees due to their size . To obviate the possibility of heart molder , do not remove any magnanimous limb as this create an entry for the fungal spores . untried trees should be maintain by correct pruning , adequate watering and by following a regular fertilization programme to avoid huitre mushroom .

Hypoxylon Canker

Hypoxylon autropunctatum is the fungus that causes hypoxylon canker . symptom of this disease are red of barque and formation of a reddish powdery substance under the bark of the Sir Herbert Beerbohm Tree . septic orbit will develop a dark ( brownish to disastrous ) crust . These area of the tree will kick the bucket . There is n’t a intervention for hypoxylon canker . It usually assail a stressed tree diagram so the way to avoid this disease is to keep a healthy Sir Herbert Beerbohm Tree . Avoid over - watering , wounds should be avoided , but if they do pass , they should be paint over . It is also important that the ground should not be compacted around the base of the tree , and to abide by a unconstipated fertilisation course of study .
