Última In vitro compatibility of microbial agents for simultaneous application to control strawberry powdery mildew (Podosphaera aphanis) Organic Eprints Sylla, Justine; Alsanius, Beatrix W.; Krüger, Erika; Becker, Dorit; Wohanka, Walter. Biological control of plant pathogens on strawberries may be improved by the simultaneous application of different biological control agents (BCAs). Therefore, the compatibility of various BCAs which had previously shown to be effective against powdery mildew (Podosphaera aphanis (Wallr.) U. Braun & S. Takam) under laboratory conditions was examined in vitro. Inhibitory effects between fungal and bacterial BCAs were demonstrated in dual culture tests on two solid nutrient media. Leaf disc assays with single and multiple strain treatments demonstrated either unaffected or significantly improved control of P. aphanis for many multiple strain treatments, even if antagonistic interactions previously occurred in dual culture tests. Highest inhibition of... Tipo: Journal paper Palavras-chave: Fruit and berries Crop health; Quality; Protection.

W.; Krüger, Erika; Reineke, Annette; Bischoff-Schaefer , Monika; Wohanka, Walter. 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....

Ano: 2013 URL: http://orgprints.org/25108/1/704 Einsatz mikrobiologischer Präparate zur Regulierung von Krankheiten an Erdbeeren - Teilprojekt: Graufäule und Echter Mehltau Organic Eprints Sylla, Justine; Krüger, Erika; Wohanka, Walter. 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... Tipo: Report Palavras-chave: Fruit and berries Crop health; Quality; Protection. Ano: 2013 URL: http://orgprints.org/25170/1/25170-11NA013-hs-geisenheim-wohanka-2013-regulierung-graufaeule.pdf Leaf microbiota of strawberries as affected by biological control agents Organic Eprints Sylla, Justine; Alsanius, Beatrix W.; Krüger, Erika; Reineke, Annette; Strohmeier, Stephan; Wohanka, Walter. 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... Tipo: Journal paper Palavras-chave: Fruit and berries Crop health; Quality; Protection.

Hauptziel des Projektes war die Entwicklung eines nachhaltigen Applikationssystems für die Kontrolle von Graufäule (Botrytis cinerea) und Echten Mehltau (Podosphaera aphanis) durch mikrobiologische Präparate im ökologischen Erdbeeranbau. Hierfür wurden insgesamt 89 BCAs (biological control agents) in Labortests auf ihre Wirksamkeit gegenüber B. cinerea und P. aphanis untersucht. Die Ergebnisse waren die Grundlage für die Auswahl von zehn BCAs für die anschließenden Kompatibilitätstests in Dualkultur und auf Blattscheiben. Diese Tests ergaben, dass sowohl antagonistische als auch synergistische Wechselwirkungen zwischen den BCAs bestehen, weshalb die kombinierte Applikation von BCAs in den Gewächshaus- und Freilandversuchen besondere Berücksichtigung...
