Tree leaf blight is a serious fungal infection that affects eucalyptus trees. Eucalyptus are native to Australia but also grow in the United States. They are considered low maintenance trees except for fungal infections like tree leaf blight.


Tree leaf blight in eucalyptus trees is caused by the fungus Phaeophleospora destructans. Symptoms include brown spots on the tree's leaves and shoots. It can distort leaf shapes and cause them to die faster. If left untreated, blight will kill the tree.


Tree leaf blight spores are carried to eucalyptus trees by the wind, animals and infected garden tools. Fungal spores need a moist environment to propagate, however.


The use of fungicide before infection reduces the risk of tree leaf blight. If infected, remove any and all infected limbs you find. Survival rates vary but removing the limbs will reduce infection of other trees.
