Chondrostereum purpureum is a fungal plant pathogen which causes Silver leaf disease of trees. It attacks most species of the rose family Rosaceae, particularly the genus Prunus. The disease is progressive and often fatal. The common name is taken from the progressive silvering of leaves on affected branches.
Like other pesticides, fungicides are numerous and diverse.This complexity has led to diverse schemes for classifying fungicides. Classifications are based on inorganic (elemental sulfur and copper salts) vs organic, chemical structures (dithiocarbamates vs phthalimides), and, most successfully, mechanism of action (MOA).
(Toenail fungus treatment is a long-haul process, the experts say.) "I do suggest Vicks to certain patients," says Del Campo, who also cites the tactic as his grandmother's favorite remedy.
The fungus attacks the host crown and stem tissues at the soil line by producing a number of compounds such as oxalic acid, in addition to enzymes that are pectinolytic and cellulolytic. [ 8 ] [ 9 ] These compounds effectively kill plant tissue and allow the fungus to enter other areas of the plant. [ 9 ]

The presence of this fungus in the soil may serve to improve the quality of it as it can help to break down organic matter and provide nutrients that the plants require. [48] However, if the mushrooms are appearing regularly it can be a sign that the soil is too moist and that the plant may be being over-watered.
The pathogen survives in the soil on infected cereal and grass residues. The fungus infects the root tissue of young plants and can spread from plant to plant in the form of hyphae growing through the soil which is why the disease is often seen in patches. The fungus blocks the conductive tissue of the plants and reduces water uptake. Early ...
When the smut invades the host plant it causes hypertrophy – the host's cells increase in size and number. (The fungus also destroys the flowering structures of the plant, so it does not make seed, but the plants can still be propagated asexually by rhizome.) In an environment such as a rice paddy, new sprouts of wild rice are easily infected ...
