| Sumario: | <p id="p1">The use of anaerobically digested slurries (ADSs) is promising strategies in resource management and agricultural production. ADSs has a potential as alternatives to chemical fertilizer. ADSs from various source materials suppressed the growth of some plant pathogenic fungi <em><italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">in vitro</italic></em>. ADS filtrates did not suppress them, indicating the effect was caused not by water-soluble substances in ADSs. In pot experiment, the efficacy of ADS from dairy cow manure (AD) for Fusarium wilt of spinach was assessed. Applying 8% (w/w) of AD significantly reduced pathogen density in soil and promoted the growth of spinach. Inoculation of a bacterial isolate AD-3 from AD, which showed high suppressiveness against Fusarium spp. <em><italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">in vitro</italic></em>, effectively controlled the disease. Based on the results, AD-3 strain is related to the disease control ability of AD that belonged to <em><italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Bacillus velezensis</italic></em>. ADSs can supply not only plant nutrients but also antagonistic microbes. For crop production, ADSs application would be effective to infected soil. It was effective for improving ADS handling that ADS was absorbed to foamed glass and dried at 60°C. To apply ADS to farmland for crop production, these findings are promising for sustainable agriculture.</p> |
