Several fungi can attack the oak tree tree , and some fungi fire only certain species of oak . However , many diseases or insect infestation manifest like symptom . For example , browning of the leaves of the canopy of an oak tree could be a symptom of oak root fungus , oak anthracnose or an louse manifestation , so further investigation is take to mold which disease is cause the problem .
Decay Fungi
A works ’s morphologic cellulose , hemicellulose and even lignin can be destroyed by decay kingdom Fungi . This decline is not seen on the outside of the oak tree tree . You will only be mindful of this decay if the bark has been murder through injury or if there is an open wound somewhere on the tree diagram . The devastation of the plant ’s structure makes the diseased tree grave due to its instability / social organization decline . A decaying Sir Herbert Beerbohm Tree can not support the weight of its limb and branches , and can easily be toppled over during a storm .
Identification of Wood Rot Fungi
Wood rotting kingdom Fungi are identifiable by their shape , color , and the formation of their fruit bodies that appear on the tree . The fruiting body are call conks or brackets , and they can be found at wound in the bark , by arm cicatrice and often by the root pennant . Fungi are divided into three group : white rot , browned rots and soft rots .
Oak Anthracnose
Oak anthracnose is a fungal disease that attacks the parting and unexampled growth of the oak tree tree . Fungal spore ( Discula quercinia ) infect the tree , which result in on an irregular basis shaped brown patch on the leaves , creating a browning of the canopy . This disease is probable to show up when weather conditions are affectionate and wet , and the lower outgrowth are most sternly affected due to high humidity level . Oak anthracnose is cosmetic in nature ; it does not kill the tree diagram . One precautionary measuring rod ( to forestall the spread of the spore ) is to prune oak tree diagram in dry atmospheric condition . They should not be pruned in April , May or June . Chemical spray are not effective in battle oak tree anthracnose .
Oak Root Fungus
Oak root fungus , also called Armillaria mellea , assault coniferous trees . This fungus creates a white-hot bunkum , which can be project when the bark is removed . It appears below the soil personal credit line , between the barque and trunk , and also between the wood of the roots and the interior of the roots . Mushrooms , a symptom of oak root fungus , seem at the base of the tree after it rains . During wet conditions the fungus grow rapidly . To slow down down the radioactive decay the affected region demand to be exposed to the air and sunlight so that it can dry out out . This can be accomplished by absent enough dirt at the pedestal of the tree to endanger the dilapidate tree trunk and etymon . Once they are exposed the sunlight and line will remove the moisture , thus slow up down the disintegration .
Artist’s Conk
Conk is yet another fungus that can attack the oak tree Sir Herbert Beerbohm Tree as well as a large number of ornamental trees . It is also known as Ganoderma applanatum . Wounds provide the entry for this disease , and the fungus can toss off the sapwood or get white rot of the sapwood . The conks are generally at the ground spirit level and seem in a hemicycle that can be from 2 to 30 inches wide , and up to 8 inch thick . ( It is called creative person ’s conk because if you cut the conk / mushroom off the tree diagram and turn it over , you could draw or write on it . )
