Abstract

In biol. control, plant extracts were investigated against some plant pathogens by many researchers. One of these plant pathogens is Botrytis cinerea Pers. It decreases the product yield by disrupting the structure of the plant. It was found that some plant extracts as Agapanthus africanus, Cinnamonum zeylanicum, Hyssopus officinalis, Satureja hortensis, Allium sativum, Tagetes patulas, and Viola odorata inhibited mycelium growth of pathogen fungi as B. cinerea, Rhizoctonia solani, Mycosphaerella pinoides, Fusarium oxysporum, Alternaria alternate. However, the extracts of Urtica dioica L., Sinapis arvensis L. and Apium graveolens Mill. were not investigate against B.cinerea. Therefore, the aim of this study was to investigate the antifungal effects of the leaf extracts of U. dioica, S. arvensis, and A. graveolens which are edible plants and sold at bazaars in Aydin vicinity, were examined against B. cinerea. Plant leaves were reduced to powder with liquid nitrogen in ceramic mortar. Boiling water, n-propanol, methanol, ethanol, acetone and Et acetate as solvents were used for extraction Fenhexamid was used as pos. control and sterile distilled water was used as neg. control. The agar well diffusion method is used for the antifungal activities of extracts The boiling water extract of U. dioica showed antifungal effect against B. cinerea while other solvents and plants did not have any effect on B. cinerea.
