[ 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 ...
A dense cluster of fruit bodies growing on a rotting stump. Several studies have shown that the spread of Armillaria root rot in eucalypt forests is associated with infected stumps that remain after an area has been logged. [28] [29] [30] Armillaria luteobubalina can persist on these stumps, using them as a source of food for up to 25 or more ...
Fusarium culmorum is a fungal plant pathogen and the causal agent of seedling blight, foot rot, ear blight, stalk rot, common root rot and other diseases of cereals, grasses, and a wide variety of monocots and dicots.
The importance of this oomycete is its vast host range and the damage it causes to major crops. This pathogen can cause root rot that stunts the host's growth and damages vascular tissue, which is especially detrimental to pear and apple orchards. It can also infect strawberry plants and cause crown rot, root rot, and leather rot of the fruit. [4]
Symptoms and signs of fungus disease are often found underground. The H. annosum infections cause an abnormal change in structure in the roots that climbs up to the butt of the tree. More than half the tree may be killed before any symptoms appear to the human eye. Basidiocarps can take up to one and a half or even three years to be visible.
Post-emergence damping off takes place after germination and results in a thinning, water-soaked stem near the plant collar, which eventually causes the collapse of the plant. [5] P. aphanidermatum can also cause root rot. Symptoms of root rot include stunted growth, chlorotic leaves, leaf drop, and wilting. The infection begins at the root tip ...
