GUIDE TO PEAR TREE PEST AND DISEASE The two chemicals which were previously available have now been withdrawn. There are no pear tree varieties which are resistant to this infection. The life cycle of pear rust can hold a cure to its control. In autumn, as the leaves of pear trees are dying, spores are released from the rust infection into the air. If they are to survive winter they must find another plant which retains its leaves over winter.

Fire Blight on Ornamental Pear The caller began to describe how the leaves on her ornamental or Bradford pear tree were turning black and the tree looked bad. After a few questions, I speculated it was a common disease called fire blight. A tour around town confirmed my initial diagnosis. Quite a few of the ornamental pear trees I observed have the tell-tale signs of fire blight. These signs include new leaves turning black or brown, new shoots suddenly dying and curling, and the remains of blooms still attached to the shoots.

Tree Fungus Diseases Root Diseases. Root rot is a common fungal disease that affects roots of otherwise healthy trees. Armillaria is a common fungal root disease in maple, oak and ornamental trees. Phytophthora root rot affects smaller nursery and landscape deciduous trees in areas with poor soil drainage.hyronectria is a fungal canker that affects woody ornamental trees and plants, fruit trees and forest trees. Seiridium canker causes infected twigs to turn brown, forming a sharp contrast against the healthy green foliage of the tree. Hardwood trees such as aspen and oak are susceptible to hypoxylon canker.

- There are two diseases that generally affect trees in the landscape this time of year. One common bacterial disease is called fireblight, which affects certain fruiting pear and apple varieties. Bees spread the fireblight bacterium as they visit the flowers in the spring.f, on the other hand, the tree is young, with only a small amount of the tree affected, then judicious pruning is in order. Bradford ornamental pear or Bradford ‘Callery’ pear does not get fireblight but the symptoms look similar to fireblight. The disease is called cedar-quince rust, which is a fungus disease.

How to Grow Pear Fruit Trees Many fruit trees have problems with insects. Many are highly susceptible to plant diseases. Pears have far fewer problems with either. They just grow and produce year after year, with very little fuss or attention. Pears get far less attention than other fruits, too. Yet, they are sweet and tasty, and nutritious.

Black Spots on Ornamental Pear Tree Leaves Fire Blight. Fire blight symptoms in ornamental pear trees include wilted, blackened leaves at the twig tips. In the spring, the bacterium Erwinia amylovora oozes from shoots and blossoms as it multiplies. Wind, rain, insects and contaminated pruning tools carry the spores to open flower buds during the spring and summer months.

Common Hardwood Tree Diseases - Prevention and Control Hardwood or deciduous trees can be harmed or killed by disease-causing organisms called pathogens. The most common tree diseases are caused by fungi. Fungi lack chlorophyll and derive nourishment by feeding on (parasitizing) trees. Many fungi are microscopic but some are visible in the form of mushrooms or conks.
