Influence of soil parameters and planting depth on black scurf development in Potato
ECOLOGY, ENVIRONMENT AND CONSERVATION, 2023Solanum tuberosum is an important vegetable crop worldwide. Among various diseases, black scurf disease caused by Rhizoctonia solani Kuhnh as emerged as a major problem and is known to cause qualitative and quantitative losses in potato.The management of R. solani causing black scurf is complex due to its soilborne nature and high level of survival and

Resistance in sweetpotato to the scurf and black rot pathogens
New Zealand Journal of Agricultural Research, 1966Abstract Over 600 sweetpotatoes (Ipomoea halalas (L.) Lam.) were evaluated for resistance to black rot (Ceratocystis fimbriata Ell. & Halst.) and 506 to scurf (Monilochaetes infuscans Eli. & Halst.). Vine cuttings from the varieties were inoculated to initially evaluate disease resistance to both fungi.

Factors associated with soils suppressive to black scurf of potato caused by Rhizoctonia solani
New Zealand Plant Protection, 2022Soils in which disease fails to develop despite pathogen presence are considered disease-suppressive. They offer sustainable, effective protection to plants against infection by soil-borne pathogens. Naturally disease-suppressive soils have been reported for diseases of a diverse range of agricultural crops worldwide yet the underlying mechanisms of ...

Biocontrol of black scurf on potato by seed tuber treatment with Pythium oligandrum
Biological Control, 2012Abstract The biological control activity of Pythium oligandrum against black scurf of potato caused by Rhizoctonia solani AG-3 was evaluated in field experiments after treatment of potato seed tubers with P. oligandrum. Seed tubers infected with black scurf sclerotia were dipped for a few seconds in a suspension of 103, 104 or 105 mL−1 P.

First report of black scurf on carrot caused by binucleate Rhizoctonia AG-U
Journal of General Plant Pathology, 2012Black scurf on carrot roots was found in Hokkaido, Japan, in 2010. An isolate of a binucleate Rhizoctonia was obtained from sclerotia on the root surface. This isolate was identified as anastomosis group (AG)-U based on cultural characteristics, hyphal fusions and the sequence of ribosomal DNA-internal transcribed spacer region. The AG-U isolate caused

Investigation on screening of diverse potato germplasm associated with black scurf resistance
Journal of Eco-friendly AgricultureBlack scurf disease caused by Rhizoctonia solani Kuhn has emerged as a major problem and is known to cause qualitative and quantitative losses in potato. The present investigation was carried out at the Agricultural Research Farm, Guru Kashi University, Talwandi Sabo during 2021-22 and 2022-23.

Occurrence, development, and losses associated with silver scurf and black dot on Colorado potatoes
American Potato Journal, 1979Silver scurf, caused byHelminthosporium solani, and black dot, caused byColletotrichum atramentarium, are pathogens of tuber periderm whose presence in Colorado was only recently reported. A field survey conducted in September 1977 revealed thatC. atramentarium was more prevalent (21.8% tuber infection) and had a wider distribution thanH.

Management of Black Scurf of Potato Caused by Rhizoctonia solani in Eastern Uttar Pradesh
Indian Journal Of Agricultural ResearchBackground: Black scurf of potato, caused by Rhizoctonia solani (Kuhn), is a significant soil-borne disease that hampers potato cultivation in Eastern Uttar Pradesh by reducing both tuber quality and yield. The pathogen’s persistence in the soil and on the seed tubers necessitate effective disease management strategies, especially under field ...
