description | Among the bacteria and fungi associated from the soil where cowpea was grown and tested for antagonism against Protomycopsis phaseoli, Bacillus sp. inhibited the radial growth, Fusarium oxysporum, yeast, Aspergillus fumigatus, Trichoderma harzianum, Trichoderma koningii and Trichoderma sp. reduced radial growth of P. phaseoli. In vitro studies showed that T. harzianum was an active hyperparasite and more effective in reducing the radial growth of P. phaseoli than T. koningii and Trichoderma sp. Spore suspensions of the three Trichoderma spp. prevented the germination of chlamydospores of P. phaseoli. In the field, when applied as spray, Trichoderma sp. was found to be more active in reducing the spread of leaf smut disease than T. harzianum and T. koningii.
Zusammenfassung
Aus Boden, in dem Augenbohnen wuchsen, wurden verschiedene Bakterien und Pilze isoliert und auf antagonistische Wirkung gegen Protomycopsis phaseoli geprüft. Bacillus sp. hemmte das Radiärwachstum des Pathogens; Fusarium oxysporum, Hefe, Aspergillus fumigatus, Trichoderma harzianum, Trichoderma koningii und Trichoderma sp. verringerten es. In‐vitro‐Versuche ergaben, dai T. harzianum ein aktiver Hyperparasit war und das Radiärwachstum von P. phaseoli stärker reduzierte als T. koningii und Trichoderma sp. Sporensuspensionen der drei Trichoderma‐Arten verhinderten die Keimung der Chlamydosporen von P. phaseoli. Nachdem die drei Trichoderma‐Arten durch Spritzen im Feld ausgebracht worden waren, verlangsamte Trichoderma sp. die Ausbreitung des Blattbrandes stärker als T. harzianum und T. koningii. |
