Butt rot is a disease of plants, mostly trees, caused by fungi. The fungus attacks the moist, poorly protected undersurface of tree trunk's thickest part (the "butt" above the root, as opposed to "top"), where the end of the stem makes contact with the soil. It may affect the roots as well, causing a disease known as root rot. It then moves up ...
There are only a few ways to manage disease caused by N. cinnabarina. One way to control the spread of this fungus is pruning branches of trees that have cankers. N. cinnabarina is a saprophyte and mainly resides in and on dead tissue, but as the fungus progresses, it invades living tissue and causes further disease. Trimming the areas so that ...
The mycelium of this fungus doesn’t grow in the soil and also its spores are not spread by wind like most fungal pathogens. [1] Infection occurs when roots of healthy trees grow in contact with infected roots. After initial contact with a living root, the mycelium grows on the bark, extending only a few millimeters into the surrounding soil.
[1] [6] Since this fungus can not move very far through soil, it relies on tree roots to help it infect neighbouring trees. In these roots, it can grow 0.1–2.0 m per year. This results in a spread of the fungus and disease gaps in the forest. These disease gaps are produced when the trees die and fall, creating gaps in the forest canopy.
A magnolia tree on the west side of Jackson City Hall in Jackson, Miss., seen Tuesday, Feb. 20, 2024, is just one of a number trees in metro Jackson lost to the drought conditions last summer.
When damage or stress occurs, the fungi will further colonize, infect, and begin living off the nutrients of the tree, flourishing in the bark and vascular system. [2] Natural stresses such as defoliation by insects, animal damage, soil nutrient depletions, drought, overcrowding, and other disease can weaken trees, enabling Hypoxylon to infect ...
