Ornamental
plants are plants grown for the decoration and beautification of indoor and
outdoor spaces. They are classified as floriculture plants, ornamental shrubs,
trees, grasses and bamboo, as well as ornamental aquatic plants. More than
2,000 genera of plants are used as ornamental plants in the world. One of the
soil pathogens that cause diseases in ornamental plants is Rhizoctonia species.
Both binucleate and multinucleate anastomosis groups of Rhizoctonia species,
which are a large and complex group, cause significant damage to ornamental
plants. These groups generally cause root and crown rot, bulb rot, wilt, bare
patch and death in ornamental plants. When the studies carried out so far on
ornamental plants in the world are examined, Rhizoctonia solani AG 2-2
IIIB, AG 4 HG I, binucleate AG A, Ba, AG G, AG U and AG T from Rosa; R.
solani AG 1, 2-1, 2-2, 4, 6, 7 from carnation; R. tuliparum, R.
crocorum, R. solani AG 1-IC, 2-t, 2-1, 2-2, 2-2IIIB, 2-2IV, 3, 4, 5 and AG
BI from tulip; R. solani AG 2-1, 2-t, 4 and 5 from hyacinth; R.
solani AG 4 HG I and 4 HG III from chrysanthemum; R. solani AG 1,
2-1, 2-t, 3, 4 HG I, 5, 6, 7 and 11 from lily ; R. solani AG 2-1, 2-t, 4
and 5 from iris; binucleate AG-U as well as AG R, CAG 7 (=AG S) and AG G from
azalea; R. solani AG 2-2 from anemone; binucleate AG U (AG-Erica) from Erica
sp. anastomosis groups were isolated. Rhizoctonia solani AG 2-2 IIIB, 4
HG-I, binucleate AG A, Fb, G, R, and AG V groups were isolated from the other
indoor and outdoor plants. When the studies conducted in Türkiye were examined,
it was reported that Rhizoctonia solani AG 4 caused root and crown rot
in Madagascar periwinkle (Catharanthus roseus L.). More studies are
needed on the detection of Rhizoctonia anastomosis groups that cause
problems in ornamental plants in Türkiye.
