Bacillus subtilis for biological protection of Taxus baccata L. in landscape gardens

Abstract

The fungistatic effect of the endophytic strain of Bacillus subtilis in park stands of Taxus baccata L. var. “Fastigiata”. The study used trees in park stands with symptoms of damage by the phytopathogenic fungus Cryptocline taxicola (All.) Petr. It was found that treatment of shoots with a suspension of microorganisms Bacillus subtillis strain krd-20 in the autumn and spring prevented the development of the disease and the fall of needles. RAPD-PCR was used to determine that the strain was capable of endophytic development and was preserved in the coniferous tree for at least six months.
