The growing bacterial resistance to antibiotics calls for the elaboration of new pathogens elimination strategies. Some of these methods are based on the conjugative transfer of recombinant plasmids able to eliminate pathogenic recipients by plasmid run-away replication or by killing activity of plasmid-encoded bacteriocins. Using live bacteria as donors of plasmid vectors carrying killing determinants requires meeting many safety restrictions in order to eliminate potential biohazard.

Phytophthora cryptogea and Phytophthora citrophthora were isolated from rotted stem base of Forsythia intermedia cv. Minigold and from substratum, respectively. Additionally Botrytis cinerea and Fusarium spp. were often isolated from diseased tissues. In the laboratory trials P. cryptogea from F. intermedia colonised and incited disease of leaf blades and stem parts of all tested cultivars. The species caused necrosis development of leaves and stem of Ligustrum vulgare, Sambucus nigra and Syringa vulgaris after 3 days of inoculation. The isolates from 7 different host plants colonised (except from Sempervivum arachnoideum) leaves and stem parts of F. intermedia cv. Minigold with the fastest spread of necrosis on plant parts inoculated with isolate from forsythia. P. citrophthora from substratum colonised leaves and stem parts of 5 tested cultivars with the quickest spread of necrosis on cv. Goldzauber and Spectabilis.

From Hedera helix and Epipremnum aureum showing necrosis of shoot base spread upwards and on leaves Phytophthora tropicalis was isolated. The species was obtained from ⅞ of Hedera and ¾ of Epipremnum diseased shoot and root parts. Additionally, Botrytis cinerea, Fusarium avenaceum and Rhizoctonia solani was recovered from some of affected plants. The chosen 2 isolates colonised petioles and leaf blades of both host plants. P. tropicalis caused necrosis of leaves of 11 tested cultivars of H. helix and 13 other pot plant species and seedlings of tomato. The fastest spread of necrosis was observed on leaves of Peperomia magnoliaefolia, Pelargonium zonale and Phalaenopsis x hybridum. The development of disease was observed at temperatures ranged from 10 to 32.5°C with optimum 30°C.

W latach 2004-2009 monitorowano występowanie chorób na drzewach i krzewach parkowych w różnych założeniach terenów zieleni w Poznaniu. Grzyby pasożytujące na roślinach oznaczano na podstawie analizy mikroskopowej zebranego materiału, kluczy mikologicznych i danych z literatury. Oprócz grzybów chorobotwórczych powszechnie występujących w Polsce zidentyfikowano również nowe patogeny, przywleczone do Europy z różnych rejonów świata: Erysiphe carpinicola na grabie pospolitym (Carpinus betulus), E. flexuosa (syn. Uncinula flexuosa) na kasztanowcach (Aesculus x carnеа i A. hippocastanum), Oidium sp. na katalpie, Microsphaera azaleae na różanecznikach. Znaczne szkody powodowały mączniaki prawdziwe - E. flexuosa na kasztanowcach, Microsphaera palczewskii na karaganie syberyjskiej (Caragana arborescens), M. azaleae na odmianach różaneczników o opadających liściach oraz rdza Cumminsiella mirabilissima na mahonii pospolitej (Mahonia aquifolium).
