A disease incident to trees, causing the bark to rot and fall off.
An obstinate and often incurable disease of a horse's foot, characterized by separation of the horny portion and the development of fungoid growths; -- usually resulting from neglected thrush.
Cankers are the evidence of certain kinds fungal and bacterial diseases. Cankers are most common on woody plant material. They appear as sickly, abnormal areas on a cane or branch's surface, sometimes seeming as though the branch is rotting from within and other times seeming as a swollen abscess that may crack open. Bacterial cankers attack some berries and tomatoes. Fungal cankers attack a wide range of plants, including landscape and fruiting trees, roses, and shrubs.
A plant disease symptom characterized by a sharply defined necrosis of cortical tissue, often sunken below bark surface.[1] Fin. Swe.
unsightly wound on woody plants caused by fungal or bacterial pathogens
dead area in plant tissues usually caused by disease.
a disease symptom on woody stems or trunks. Resembles an open break or wound and often persists from year to year.
necrotic, localised diseased area.
A localized, dead, often sunken or cracked area on a stem, twig, limb, or trunk.
a definite, sunken or cracked dead area on the stem or branch that is surrounded by living tissues.
a dead area on the stem or trunk of a tree or shrub
a definite, localized, usually dry, dead, often discolored, sunken or cracked area surrounded by living tissue
a disease that is seen on living bark and sap-conducting tissue
a localized area on the stem or branch of a tree, where the bark is sunken or missing
a localized diseased area or lesion in the bark of a woody plant and often results in an open wound
a localized necrosis of the bark and cambium on stems, branches, or twigs
a necrotic (dead), often sunken area on a stem, trunk, or branch of a plant
an infection of the bark and outer vascular tissue of a tree or shrub
A sore or lesion on the trunk or stem of a canter. Possible sign of dieback.
Canker is a fungal disease that can affect shoots
A lesion of usually sunken, decayed tissue found most often on plant stems or branches.
A dead area on a stem surrounded by living cortical tissues.
a disease of woody plants characterized by sharply delimited necrosis of the cortical tissues and malformation of the bark caused by recurring localized killing of the cambium layer.
An erosive eruption on a stem or truck, usually exuding a viscous liquid or the spore of the fungus that causes it.
a disease of the bark and cambium that causes a usually well defined sunken or swollen necrotic lesion
A localized area of dead tissue on a stem or branch caused by fungal or bacterial organisms and characterized by progressive or intermittent killing at the margin; may be perennial or annual. Includes stem galls for the purpose of the ITFD.
A disease of the European Oak which destroys the structure in the veneer and appears as open defect in advance stadium. Very difficult to recognize in the bark.
An imprecise term usually used for a plant disease characterized (in woody plants) by the death of cambium tissue and resulting loss and/or malformation of bark, or (in non-woody plants) by the formation of sharply delineated, dry, necrotic, localized lesions on the stem. The term "canker" may also be used to refer to the lesion itself, particularly in woody plants. ( 16)
A localized necrotic lesion of the cambium.
An imperfection on the trunk, limb or twig of a tree caused by an organism that kills a part of the tree's tissue. Canker causing organisms sometimes exist in some sort of a balance with the host, never killing enough tissue to cause death. Cankers tend to weaken trees at the points where they are growing causing the tree to eventually break.
Dead cells on the branches or trunk of a woody plant - tree or shrub.
sunken area in the bark caused by wounding or disease honeydew sugary, sticky substance secreted by sucking insects taproot central root on young trees that heads straight down
A necrotic, localized disease area with a sharp line of demarcation between healthy and diseased tissue. Usually on trunks or canes.
An oval or circular killed area on a stem or branch; usually with a shrunken surface.
A fungal disease; affected shoots die back often-dark sunken areas on trunk or stems.
A dry, discolored, sunken, or cracked area on a stem, branch, or trunk. Caused by pathogens or injuries. Generally have distinct border between diseased area and healthy tissue.
Disease-damaged area of a tree usually caused by fungus or bacteria.
