ABSTRACT

The experiment studied the effect of 14 fungi species isolated in the years 2001-2003 from the shoots of highbush blueberry (Vaccinium corymbosum L.) on the growth of Topospora myrtilli. Besides, the effect of biopreparations of animal and plant origin: Biochikol 020 PC and Biosept 33 SL, was examined on T. myrtilli. Trichoderma harzianum and T. koningii belong to the fungi that inhibited the growth of the pathogen in the strongest manner. The studied species from genus Trichoderma caused degeneration of the hyphae and the dying out of the pathogen’s colonies already eight days after their common growth. The fungi inhibiting the growth of T. myrtilli also included: Altenaria alternata, A. raphani, Epicoccum purpurascens and Penicillium decumbens. Among those, only Epicoccum purpurascens formed an inhibition zone in common growth with T. myrtilli. The studies conducted on the effect of biopreparations on T. myrtilli showed that both Biochikol 020 PC and Biosept 33 SL considerably limited the growth and development of the pathogen. Biosept in the concentration of 0.3% caused very strong inhibition of the growth of the hypha and their deep degeneration.

Key words: antagonistic fungi, biopreparation, Topospora myrtili, Vaccinium.
