Ziel der Projektverlängerung war es, die Ergebnisse aus den vorangegangenen Untersuchungen (Projekt: FKZ 06OE354) zum Einsatz von mikrobiologischen Präparaten (BCAs) gegen Graufäule (Botrytis cinerea) und Echten Mehltau (Podospharea aphanis) an ökologisch kultivierten Erdbeeren in einer weiteren Vegetationsperiode abzusichern sowie den Einsatz von mikrobiologischen Präparaten im Integrierten Erdbeeranbau zu erproben. Im Freilandversuch zur Wirkung der BCAs RhizoVital®42 fl. (Bacillus amyloliquefaciens), BoniProtect®forte (Aureobasidium pullulans) und Naturalis® (Beauveria bassiana) gegen Graufäule konnten die vielversprechenden Ergebnisse aus dem Freilandversuch des vorangegangenen Projektes FKZ 06OE354 nicht bestätigt werden. Ergebnisse der... |

Currently, there is little knowledge of the establishment of repeatedly applied biological control agents (BCAs) in the phyllosphere of plants and, in particular, their interactions with the resident microbiome. Under field conditions, the BCA Aureobasidium pullulans was applied as a model organism to organically grown strawberries during two subsequent years (2011, 2012), either as single strain treatment or with the co-application of the entomopathogenic fungus Beauveria bassiana. Fungal and bacterial communities of strawberry leaves were investigated by means of plate counts and 454 pyrosequencing. The establishment of the introduced A. pullulans strains considerably differed between the two years, presumably due to distinct environmental conditions.... |

The increasing use of biological control agents (BCAs) against Botrytis cinerea in strawberry raises the question of whether there are any undesirable impacts of foliar applications of BCAs on nontarget microorganisms in the phyllosphere. Therefore, our objective was to investigate this issue within a field study. Strawberry plants were repeatedly sprayed with three BCAs—namely, RhizoVital 42 fl. (Bacillus amyloliquefaciens FZB42), Trianum-P (Trichoderma harzianum T22), and Naturalis (Beauveria bassiana ATCC 74040)—to suppress Botrytis cinerea infections. Microbial communities of differentially treated leaves were analyzed using plate counts and pyrosequencing and compared with the microbial community of nontreated leaves. Plate count results indicate that... |

The aim of this study was to investigate the possible enhancement of leaf decomposition by means of different nitrogen containing products or mulching of leaves and the resulting reduction of the ascopore potential of Venturia inaequalis. For each treatment 30 scabbed leaves of 'Jonagold' were placed in wire-mesh cages with or without fleece to avoid or allow activity of earthworms, respectively. The leaves were treated as follows: untreated as a control, spraying or addition of: urea (46% N), Siapton (organic liquid fertiliser, 7% N), horn meal (organic fertiliser, 10-14% N), Radivit (decomposition enhancer, 9% N) and slightly rotted manure (0,5% N). All treatments were adjusted to a similar amount of N per m2. In addition leaves in one treatment were... |
