Insects, fungi and bacteria can all be referred to as "tree pests" because they all can negatively on the health of a tree. Insects usually lead to not only the leaves at the tops of the trees to be brown, but, but affects the entire tree. Trees with brown suffer, dying leaves at the tips of the branches of "forest dieback", the dies to the tree from the tips inward relates. Die usually by fungi or bacteria.
Trees suffer pests flying die are relatively easy to recognize. They usually leaves at the tips of the branches that are brown shriveled or rotten. This is most noticeable in spring when new growth is infected. New branches, shoots and flowers will look wet, black and show stunted or deformed growth. Furthermore, if the death is caused by a fungus that can spots on the leaves, and bile (swollen growths) or crayfish (areas dry, cracked wood) can appear also appear on the tree trunk and branches.
Fire blight is a common cause of forest decline and the bacteria Erwinia amylovora is the most common cause of fire blight – so called because the trees are affected as if they were burned by the fire at the tips of the branches look. These bacteria usually affects fruit trees, especially pear and apple. Botryosphaeria is a large family of fungi that cause death in the trees. The spores in cancers and biliary reproduce to infect what belt or branches and even the trunks of trees, cutting off the supply of nutrients and what the tree dying from the tips inward. Anthracnose is a common group of fungal diseases that infect shade trees, group with the same result as the Botryosphaeria.
Trees can suffer from death only show symptoms to an area of the tree. If that is the case, the affected area should be removed several inches below circumcised obvious crabs or bile. This can prevent the spread of bacteria or fungi. Collect infected leaves and destroy them, as many fungi can overwinter in the soil and get up again next spring to infect the tree. Spray the tree with a fungicide when the infection is low. In severe cases, and when the whole tree is infected, it could not be anything you can do to the tree can be treated.
Blossom sprays and fungicides fire blight and other bacterial and fungal diseases Seize to prevent your tree. Sprinkle it in the spring, and repeat the instructions on the package addressed. This is especially important during the unusually wet springs, like many fungal spores to travel on the water. Hold. Your tree healthy and not to damage the bark with garden tools, such as some fungi enter the tree through wounds in the wood Finally, to allow for plenty of space around the tree. Air circulating around the tree quickly no water left to dry sitting on the leaves – water, could harbor fungal spores.
