  author={C. Eken and Erkol Demirci},
AbstrastThree-hundred-twenty-five isolates ofRhizoctonia (215R. solani and 110 binucleateRhizoctonia) were obtained from roots and crowns of alfalfa, sainfoin and common vetch grown in Erzurum, Turkey. The isolates were assigned to five anastomosis groups (AG) ofR. solani (AG-2-1, AG-3, AG-4, AG-5, and AG-10) and two anastomosis groups of binucleateRhizoctonia (AG-I and AG-K). In pathogenicity tests on alfalfa, sainfoin and common vetch, the highest disease severities were caused by isolates of… 
Molecular and conventional identification and pathogenicity of Rhizoctonia solani isolates from tobacco (Nicotiana tabacum L.) in Samsun, Turkey.
All selected Rhizoctonia solani isolates were highly virulent to tobacco plants, causing symptoms resembling damping-off, except for isolate 55TkTB63, which was only moderately virulent.
Anastomosis groups and pathogenicity of binucleate Rhizoctonia isolates associated with stem canker of potato in China
Potato stem canker caused by Rhizoctonia solani commonly occurs in potato-growing regions around the world, but little is known about whether binucleate Rhizoctonia (BNR) can incite this disease on
Characterization of Rhizoctonia solani Associated with Black Scurf in Cyprus.
This is the first comprehensive study to elucidate the AG composition, pathogenicity and other biological aspects of R. solani isolates associated with potato black scurf in Cyprus.
First report of binucleate Rhizoctonia AG-K causing root rot on chickpea
This is the first report of binucleate Rhizoctonia AG-K as a pathogen of chickpea in Turkey and also in the world, and it is found that the isolates were clustered in the same branch with the reference isolates ofAG-K.
Isolation and Identification of Binucleat Rhizoctonia spp. from Wheat Field Soils in the Central Anatolia Region, Turkey
AG C identified in this study is first record for Turkey, and also AG A, AG E, AG G and AG H groups were determined to be first in the wheat field soils in Turkey.
Rhizoctonia Species and Anastomosis Groups Isolated from Tomato and Cucumber in Erzincan , Turkey
Rhizoctonia comprises both multinucleate and binucleate species which are further divided into anastomosis groups (AGs). Currently, the multi nucleate isolates R. solani Kühn (teleomorph:
Determination of Rhizoctonia species and anastomosis groups in wheat production areas in Kayseri, Kırşehir, Nevşehir and Aksaray provinces.
It was determined that the most virulent group of Rhizoctonia species and anastomosis groups in wheat production areas in Kayseri, Kırşehir, Nevsehir and Aksaray provinces is AG 4 HG II.
Damping-off on alfalfa caused by a binucleate Rhizoctonia in Mérida, Venezuela.

Characterisation of fungal pathogens causing basal rot of lettuce in Belgian greenhouses
A correlation could be found between the occurrence of the pathogens and the growing season, and the information obtained in this study will be most useful in the development of an alternative control strategy for causal agents of basal rot.
New Anastomose Group of Binucleate Rhizoctonia Causing Leaf Wilt Disease of Erica sp
The pathogen was isolated and purified from diseased leaves, and was identified as binucleate Rhizoctonia sp.


Introduction — The Genus Rhizoctonia
The genus Rhizoctonia was described by DeCandolle in 1815 as the type species, which was published around the time when the potato late blight broke out in Europe, which caused the noteworthy potato famine in Ireland.

Fungal rootlet colonization and forage yields of alfalfa in fungicide-treated field plots.
Preplant soil treatments with metham-sodium initially reduced rootlet colonization by species of Fusarium and Pythium and increased root-length densities but had no effect on cumulative forage yields during the three harvest seasons.
Reactions of Dry Bean, Lima Bean, and Soybean Cultivars to Rhizoctonia Root and Hypocotyl Rot and Web Blight
Agar plate assays were not satisfactory for determining differences in host resistance and that investigations should be based on potted plant assays, and data from agar plate and potted Plant assays for hypocotyl and root rot were either not correlated or were only weakly correlated.
Forage and Oilseed Legume Diseases Incited by Rhizoctonia Species
Diseases caused by Rhizoctonia solani Kuhn reduce its stand, yield, forage quality and persistence of alfalfa, and will also lessen its resistance to environmental stresses and its ability to utilize water and nutrients.
Safranin O as a rapid nuclear stain for fungi.
Maximum germination of both basidiospores and oidia was obtained on agar media containing cornmeal and malt extract with malt-extract-liquid medium, apparently providing a stimulatory substance in sufficient quantity to yield maximum percent germination.
Identification of Rhizoctonia Species
The phytochemical properties of Rhizoctonia mellifera have been investigated and suggest that it is a good feedstock for other phytochemicals such as phosphorous and nitrogen.
