Rhizoctonia solani is a soil-born necrotroph from the kingdom Fungi's domain Eukarya (Ajayi-Oyetunde and Bradley 2018). Septate hyphae, multi-nucleate cells, and brown pigmentation are all features of R. solani. Based on hyphal incompatibility and host specificity, isolates are divided into 12 anastomosis groups (Anderson 1982).

These Rhizoctonia solani-like fungi are saprophytic, do not cause disease, and feed on dead organic matter. Following invasion of the host by Rhizoctonia solani, sexual spores are formed on specialized structures called basidia. Four spores are produced on each basidium.

Rhizoctonia solani, a form of rot which attacks many plants, can spread rapidly at temperatures below 20ºC (68ºF). It is found in the upper layers of the soil, where it can remain for years on end. It attacks the plant at collar level, progressing to the tuber and the root system.

Aug 2, 2017 · Rhizoctonia solani, the most important species within the genus Rhizoctonia, is a soilborne plant pathogen with con-siderable diversity in cultural morphology, host range and aggressiveness. Despite its history as a destructive pathogen of economically important crops worldwide, our understanding of its taxonomic relationship with other ...

Rhizoctonia solani is an important phytopathogenic fungus with a wide host range and worldwide distribution. The anastomosis group AG1 IA of R. solani has been identified as the predominant causal agent of rice sheath blight, one of the most devastating diseases of crop plants.

May 22, 2022 · Rhizoctonia solani is a seed- and soil-borne pathogen, which survives through sclerotia and mycelia in infected seeds or soil in tropical environments.

Rhizoctonia solani isa fungus that attacks tubers, underground stems, and stolons of potato plants. Although it probably occurs wherever potatoes are grown, it causes economically significant damage only in cool, wet soils.

Jan 13, 2011 · Rhizoctonia solani is a fungal species complex, including pathogens and nonpathogens, important to forestry and agriculture (Sneh et al., 1991; Nagaraj et al., 2017). It causes a variety of symptoms and diseases (e.g., root, crown, and stem rot; damping-off; and wilting) in numerous economically important crops ( Anderson, 1982 ; Ogoshi, 1987 ...

Aug 18, 2023 · Rhizoctonia solani causes a seedling disease of cotton. Symptoms caused by R. solani, such as seed rot, preemergence damping-off, and postemergence damping-off with sunken lesions on the hypocotyl (often referred to as sore shin), can be challenging to distinguish from those caused by other pathogens.

4 days ago · The hyphae were multinucleate, containing four to nine nuclei per cell. After 15 days, some isolates produced dark brown sclerotia. Based on these morphological characteristics, isolates were tentatively identified as Rhizoctonia solani Kühn (Parmeter, 1970). To confirm the anastomosis group (AG), two isolates (RsHg4 and RsHg8) were selected ...

Mar 11, 2011 · Rhizoctonia root rot caused by Rhizoctonia solani Kühn is a widespread and important disease problem on many crops (Führer Ithurrart et al., 2004). Rhizoctonia solani can cause disease on at least ...

There are three types of Rhizoctonia blight: large patch, a blight of warm-season grasses that is caused by Rhizoctonia solani; brown patch, a blight of cool-season grasses that is also caused by R. solani; and yellow patch, a blight of annual and Kentucky bluegrass caused by R. cerealis. When weather conditions are not favorable for disease development, both species can survive …

Rhizoctonia solani has a decomposer or saprophytic phase and a parasitic phase and can be active in both simultaneously. Previous crop stubble is a food source and host for the decomposer (saprophytic) phase, allowing the fungus to survive year-round.
