Opis (eng)

Abstract Pseudomonas chlororaphis is a bacterium used as a soil inoculant in agriculture and horticulture. It can act as a biocontrol agent against certain phytopathogenic fungi via production of phenazine type antibiotics. Phytopathogenic fungi are responsible for several plant diseases in different medicinal plants and cause very important economic losses in Serbian plantation. Among them, Alternaria sp., Phoma sp. and Drechslera tetramera are known as major plant pathogens, whereby at least 20% of agricultural spoilage is caused by Alternaria species. In this study, we examined the antifungal activity of indigenous Pseudomonas chlororaphis isolates against the phytopathogenic fungi Alternaria sp., Phoma sp. and Drechslera tetramera, which had infected anise (Pimpinella anisum L., fam. Apiaceae), using in vitro inhibition tests. The obtained results showed that studied antibioticproducing Ps. chlororaphis isolates inhibited the tested fungi as follows: D. tetramera in the range from 3.85-69.23%, Alternaria sp. in the range from 5-50%, and Phoma sp. in the range from 0-50%. In general, it has been concluded that studied P. chlororaphis isolates have potential in controlling plant diseases caused by phytopathogenic fungi Alternaria sp., Phoma sp. and D. tetramera, whereby the bacterial isolates with the highest inhibitory potential will be selected for further experiments.
