Hymenoscyphus fraxineus is an ascomycete fungus that causes ash dieback, a chronic fungal disease of ash trees in Europe characterised by leaf loss and crown dieback in infected trees. The fungus was first scientifically described in 2006 under the name Chalara fraxinea .
Forest dieback (also "Waldsterben", a German loan word, pronounced [ˈvaltˌʃtɛʁbn̩] ⓘ) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, [1] and more.
Rhododendron viscosum is also known as the swamp azalea, catch-fly azalea (due to sticky and glandular hairs), and clammy azalea. [1] Its large land area includes growth on the coastal area of Mississippi, and along the east coast from Florida to Maine. In addition to the coastal areas, the swamp azalea can be found inland in higher elevations.
Dieback may refer to a number of plant problems and diseases including: Forest dieback caused by acid rain, heavy metal pollution, or imported pathogens; The death of regions of a plant or similar organism caused by physical damage, such as from pruning; Those caused by the genus Eutypa, such as Eutypa dieback
Colletotrichum capsici is a species of fungus and plant pathogen which causes leaf blight on Chlorophytum borivilianum, basil, chickpea and pepper as well as dieback in pigeonpea and anthracnose in poinsettia.
Dieback is characterized as a ‘dead arm’ and a loss of spur positions. More symptoms include stunted shoots in the spring, delay or lack of growth in the spur positions of the bud burst, bleached canes and necrotic buds. Bud necrosis, bud failure, and the dieback of arms are all a result of the necrosis of the host's vascular system. [9]
Forest pathology is the research of both biotic and abiotic maladies affecting the health of a forest ecosystem, primarily fungal pathogens and their insect vectors. [1] [2] It is a subfield of forestry and plant pathology.
