The antifungal and herbicidal activity of Trachystemon orientalis (L.) G. Don aqueous plant extracts
were evaluated against important plant pathogenic fungi (Sclerotinia sclerotiorum Lib. De Bary, Alternaria solani
(Ellis & G. Martin) Sorauer, Phytophthora infestans (Mont.) de Bary, and Botrytis cinerea Pers.,) and Cuscuta
campestris Yunck. Antifungal activity experiments were conducted under laboratory conditions and herbicidal
activity was tested in the greenhouses. The leaves, root and flowers of aqueous extracts of T. orientalis at 1, 3,
5, 7, 10 and 20% doses were applied on Potato Dextrose Agar (PDA) and tested to plant diseases, and the dose
of 5% of flowers and leaves aqueous extracts of T. orientalis were examined on tobacco (Nicotiana tabacum L.)
and sugar beet (Beta vulgaris L.) against C. campestris. Antifungal activity displayed differences inhibited effects
on mycelium growth of plant pathogenic fungi according to increasing extract dose and plant pathogenic fungi.
The results showed that mycelial growth inhibitions were found effective in all extracts (leaf, flower and root) on S.
sclerotiorum 0 to 100%, on A. solani 21 to 100%, on P. infestans 25 to 100% and, on B. cinerea 0 to 100% depending
on the extract dose. According to herbicidal activity result the development of C. campestris has been reduced by
looking the fresh (in tabocco: 0.3639 g and in sugar beet:0.6749 g) and dry (leaf extracts: in tabacco:0.0675 g and
sugar beet: 0.1546 g; flower extracts: in tobacco 0.3246 g and sugar beet: 0.3421g) weight.
