The effect of bio-preparations on the infestation of tubers by  spp.

<trans-abstract xml:lang="pl" xmlns="http://www.w3.org/1999/xhtml">W latach 2005 - 2007 badano wpływ zaprawiania sadzeniaków i czterokrotnego opryskiwania roślin ziemniaka biopreparatem Polyversum (s.a. Pythium oligandrum) i Biochikolem 020 PC (s.a. chitozan) na porażenie bulw przez Streptomyces spp.Na podstawie uzyskanych wyników z doświadczeń polowych stwierdzono, że we wszystkich latach badań stosowane preparaty w sposób istotny ograniczyły procentowe porażenie bulw przez Streptomyces spp. Spośród preparatów biologicznych najlepsze działanie ochronne wykazał biopreparat Polyversum, zastosowany do zaprawiania sadzeniaków i czterokrotnego opryskiwania roślin w okresie wegetacji.</trans-abstract>
