Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...
Laminated root rot also known as yellow ring rot is caused by the fungal pathogen Phellinus weirii. Laminated root rot is one of the most damaging root disease amongst conifers in northwestern America and true firs , Douglas fir , Mountain hemlock , and Western hemlock are highly susceptible to infection with P. weirii .
Armillaria root rot is a fungal root rot caused by several different members of the genus Armillaria. The symptoms are variable depending on the host infected, ranging from stunted leaves to chlorotic needles and dieback of twigs and branches. However, all infected hosts display symptoms characteristic of being infected by a white rotting ...
These basidiospores are carried long distances by wind currents. They infect trees (usually conifers) through damage such as freshly cut stumps. Once on the stump the fungus colonizes and moves into the root via mycelium. Heterobasidion annosum moves short distances from the roots of an infected stump through root grafts with other trees. It ...
Similarly to apple trees, crown rots of strawberries caused by P. cactorum can be partially diagnosed by cutting the crown of the plant and observing brown vascular tissues, and root rots by brown or black stunted roots. [7] Leather rot of strawberry is an additional disease affecting strawberry plants, with P. cactorum being the causal agent ...
The stump (and tap root) that is left in the ground after a tree has fallen or has been cut is the primary source of fatwood, as the resin-impregnated heartwood becomes hard and rot-resistant after the tree has died. Wood from other locations can also be used, such as the joints where limbs intersect the trunk.
Brown root rot disease is a destructive plant disease caused by fungi, primarily Phellinus noxius. [1] It affects a wide range of plants, including trees, shrubs, and crops, leading to root decay, poor growth, and often the death of the plant. This disease is common in tropical and subtropical regions with warm, moist climates. [2]
