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).
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 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 ]
When fitness of plant and fungus become tightly intertwined, it is in the best interest of the endophyte to act in a manner beneficial to the plant, pushing it further toward the mutualism end of the continuum. Such effects of seed defense can also occur in dense stands of conspecifics through horizontal transmission of beneficial fungi. [84]
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 no dead tissue remains is important because this removes the areas ...
