Crown rot, also known as Phytophthora, is a disease that affects the root system. This slow-moving disease can take years to manifest symptoms and kill the host tree. The most noticeable symptoms are foliage loss, dieback, and discolored leaves, but by the time you notice these symptoms, it’s probably too late. Young trees are more susceptible to crown rot because their root systems are not as developed compared to an older tree. To protect your trees against this disease, you need good drainage. Crown rot thrives in low-lying areas and flood zones.
Anthracnose, commonly referred to as leaf canker, is a sign associated with several different infections. Canker attacks new twigs, causing them to die and leave a knotted scar on the branch. The damaged trunk or limb will make it more difficult for future growth to come in at the right angle. Leaves infected with canker will develop brown spots or holes. Invasive fungi and bacteria are usually to blame for canker, depending on the type of tree. For example, citrus trees are susceptible to a specific fungus called Xanthomonas axonopodis. Most of these diseases are incurable, and they’ll spread to other trees on your property that are of the same species.
This disease is carried by sap-feeding beetles who prefer oak trees. It can also pass from one tree to another when the roots of two different trees meet underground. The most obvious sign of oak wilt is sudden and rapid leaf drop, a rare condition among oak trees. White oak trees will drop discolored brown leaves whereas the leaves on a red oak will turn a dull, olive green.
Fire blight is a highly contagious, gram-negative bacterium that affects trees in the Rosaceae family. Pear trees are the most vulnerable to catching this disease as well as apple, crabapple, hawthorn, raspberry, and quinces. The disease is called fire blight after the burnt appearance of the leaves and new twigs. The sign of the shepherd’s crook is another sign to watch for. The blossom shoots will shrivel and turn black, taking on the shape of a shepherd’s cane.
