What does Rhizoctonia solani do to plants?
R. solani is best known to cause various plant diseases such as collar rot, root rot, damping off, and wire stem. R. solani attacks its hosts when they are in their early stages of development, such as seeds and seedlings, which are typically found in the soil.
What causes Rhizoctonia solani?
Spread: This is a soil borne pathogen, it persists in soil as mycelium and sclerotia (small, brown, long-term survival structures). The disease is spread by the movement of contaminated soil, plant material, tools and equipment.
What kind of disease is Rhizoctonia What does it cause?
Rhizoctonia solani This versatile organism is capable of infecting and causing a myriad of diseases, including seed decay, post- and pre-emergent damping-off, stem cankers, root rot, fruit decay, and in some instances, foliar blights.
What is parasite Rhizoctonia solani?
Rhizoctonia solani Kiihn, an important soil-inhabiting facultative parasite, has an extremely wide host range. More than 200 species of flowering plants are host to this fungus (10) but little is known regard- ing the capacity of R. solani to parasitize organisms other than seed plants.
How do you control Rhizoctonia solani?
How To Control Rhizoctonia
- Since Rhizoctonia is a soilborne disease, do not reuse growing medium from infected plants.
- Remove diseased plants and plant residues from the growing area.
- Use brand new containers.
- Avoid contact with soil as it often is a source of Rhizoctonia.
How do you treat Rhizoctonia solani?
Treatment Decisions For areas where large patch and yellow patch are chronic, fall fungicide applications may be necessary; otherwise, make fungicide applications soon after the first symptoms of disease are seen. Some fungicides that are active against R. solani may not be specifically labeled for R. cerealis.
How do you treat Rhizoctonia?
How is Rhizoctonia web blight treated?

- Allow soil to dry out. If you just noticed that there’s some standing water or leaf change and you aren’t sure if it’s quite yet root rot, allow the soil to air out.
- Remove all browning leaves.
- Remove old soil.
- Cut off dead and decaying roots.
- Repot with new soil.
Is Rhizoctonia a fungus?
Rhizoctonia, a soil-borne fungus, is known to cause root rots, stem rots, damping-off and, in some cases, a blight of leaves. The fungus is able to persist in the soil as hyphae and sclerotia. It generally does not produce any spores except in its sexual stage, which occurs very rarely.
