Dry rot is the term given to brown rot decay caused by certain fungi that deteriorate timber in buildings and other wooden construction without an apparent source of moisture. The term is a misnomer [ 2 ] because all wood decaying fungi need a minimum amount of moisture before decay begins. [ 3 ]
Seed pieces may rot completely before they have the chance to be planted. The genus that causes dry rot of potato, Fusarium, is a fungus. Signs of Fusarium can be seen on an infected potato, and include white or pink mycelia (masses of vegetative fungal tissue) and very colorful spores that can be blue, black, purple, grey, white, yellow, or ...
The term brown rot replaced the general use of the term dry rot, as wood must be damp to decay, although it may become dry later. Dry rot is a generic name for certain species of brown-rot fungi. Brown-rot fungi of particular economic importance include Serpula lacrymans (true dry rot), Fibroporia vaillantii (mine fungus), and Coniophora ...
Serpula himantioides is a species of fungus that causes damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. It has been found on all continents except for Antarctica. Recent molecular work demonstrates that S. himantioides is a species complex including multiple cryptic lineages. [2]
Dry rot treatment refers to techniques used to eliminate dry rot fungus and alleviate the damage done by the fungus to human-built wooden structures. Dry rot (Serpula lacrymans) is considered difficult to remove, requiring drastic action. Remedial timber treatment and damp proofing companies typically recommend stripping out of building fabric ...
Symptoms of dry rot of yam include necrotic lesions beneath the skin, followed by yellow lesions below the outer skin of the tuber. External cracks appear in the skin of the tuber. The infections created by the nematode can serve as external opening facilitating fungi and bacteria colonization, causing wet rot. [1]
Symptoms are visible at wound sites where the fungus begins to rot the plant. Gray masses with a velvety appearance are conidia on the plant tissues are a sign of plant pathogen. [7] These conidia are asexual spores that will continue to infect the plant and surrounding hosts throughout the growing season making this a polycyclic disease.
Outbreaks of black root rot in agricultural systems and the wild often occur in circular patches. [4] Despite the pathogen's wide host range, disease signs and symptoms typically present in the same manner regardless of host species. Symptoms and disease progression have been likened to those caused by Phytophthora spp. and Armillaria spp. [5]
