In vitro effect of plant extracts and exudates on mycelium growth of fungal plant pathogens
Slavtcho Slavov, Petar Yordanov and Milena Nikolova
Abstract: Phytopathogenic fungi are responsible for the destruction of crop cultures worldwide. Artificially created chemical compounds used for the control of plant pathogens so far are often harmful for the environment and are proved to be damaging to other plant and animal species. Natural plant extracts are promising to overcome the problem. In this study methanol extracts and/or acetone exudates from three different plant species (Tagates patula L., Tanacetum vulgare L. and Salvia officinalis L.) were evaluated in vitro for their effect on the mycelium growth of four phytopathogenic fungi: Alternaria alternata, Fusarium oxysporum, Botrytis cinerea, Phytophthora cambivora. The strongest inhibition effect was expressed in case of the estimation of T. vulgare acetone exudate on the mycelium growth of P. cambivora.
