Biological soil disinfestation (BSD) is an effective and environmentally friendly way to suppress soil-borne pathogens. Although it is increasingly used in USA, the Netherlands and Japan, its precise mechanism has not been well quantified so far. Quantitative real-time PCR, denaturing gradient gel electrophoresis and high performance liquid chromatography were used for investigating the role of organic acids in the mechanisms of BSD. The results showed that BSD significantly reduced the population of Fusarium oxysporum in soil. Simultaneously, in BSD treatments, the soil pH significantly decreased and some organic acid producers, such as Clostridia sp., were observed. Four kinds of toxic organic acids to F. oxysporum were detected in soil solutions of BSD treatments. Acetic acid and butyric acid were the primary organic acids, followed by small amounts of isovaleric acid and propionic acid. The verification test directly demonstrated that the toxic organic acids with the maximal doses detected in BSD significantly suppressed F. oxysporum, Rhizoctonia solani and Ralstonia solanacearum.

“…A broad spectrum of pathogens and nematodes has been markedly suppressed by this method Uematsu et al 2007;Momma 2008;Momma et al 2010). It has been reported varieties of organic materials, such as ethanol, molasses, broccoli, cover crops, animal and green manure, and so on, are effective in BSD treatment (Shinmura 2002;Momma et al 2011;Núñez-Zofío et al 2011). However, these organic materials sometimes are not accessible and economical in fields.…”

Effects of biological soil disinfestation and water regime on suppressing Artemisia selengensis root rot pathogens

et al. 2015

Purpose Biological soil disinfestation (BSD) is an effective non-chemical method to control soil-borne disease by incorporating organic amendments into soil under flooding conditions. For suppressing Artemisia selengensis root rot pathogens (Fusarium oxysporum f. sp. cubense (FOC), Phytophthora spp., and Pythium spp.), the effects of BSD treatment using maize straw as organic material and water regime were investigated by greenhouse experiments. Materials and methods Pathogens infested soil was filled in greenhouse pots and incorporated with maize straw at rates of 0.2 %, 0.5 %, and 2 % (w/w) under flooded or water-saturated (100 % water-holding capacity) conditions at 25-35°C for 25 days. Results and discussion The population of A. selengensis root rot pathogens was effectively reduced after BSD treatments with all three maize straw application rates, and the largest reduction was reached up about 90 % at 2 % application rate.No obvious difference in suppressing effect was observed between flooded and water-saturated soil conditions with the same application rate of maize straw. BSD induced bacterial community structure shift and biodiversity enhancement. Two toxic organic acids producers, Clostridium and Bacillus spp., were found as predominant populations in both flooding alone and BSD treatments, while four types of organic acids, acetate, propionate, butyrate, and isovelerate were only detected in BSD treatments. Besides, increasing soil pH and organic matter with concomitantly decreasing nitrate occurred in BSD-treated soils. Conclusions Maize straw is an effective BSD organic material, which might also provide a potential and environmentfriendly disposal strategy of crop residues. Saturating soil to reach 100 % WHC was a good alternative to soil flooding in BSD. Bacterial community shifts, organic acids accumulation, and soil properties changes indicated multiple ways that might be involved in suppressing A. selengensis root rot pathogens during BSD treatment.

“…Despite the carbon source used, ASD-mediated pathogen control has been found to involve the products of microbial fermentation (i.e., volatile fatty acids, acetate, butyrate, etc. ), lowered soil pH and redox potential, the release of Mn 2+ and Fe 2+ , and elevated soil temperature [6,8,10,[16][17][18].…”

Temporal Responses of Microbial Communities to Anaerobic Soil Disinfestation

et al. 2019

Anaerobic soil disinfestation (ASD) is an organic amendment-based management tool for controlling soil-borne plant diseases and is increasingly used in a variety of crops. ASD results in a marked decrease in soil redox potential and other physicochemical changes, and a turnover in the composition of the soil microbiome. Mechanisms of ASD-mediated pathogen control are not fully understood, but appear to depend on the carbon source used to initiate the process and involve a combination of biological (i.e., release of volatile organic compounds) and abiotic (i.e., lowered pH, release of metal ions) factors. In this study, we examined how the soil microbiome changes over time in response to ASD initiated with rice bran, tomato pomace, or red grape pomace as amendments using growth chamber mesocosms that replicate ASD-induced field soil redox conditions. Within 2 days, the soil microbiome rapidly shifted from a diverse assemblage of taxa to being dominated by members of the Firmicutes for all ASD treatments, whereas control mesocosms maintained diverse and more evenly distributed communities. Rice bran and tomato pomace amendments resulted in microbial communities with similar compositions and trajectories that were different from red grape pomace communities. Quantitative PCR showed nitrogenase gene abundances were higher in ASD communities and tended to increase over time, suggesting the potential for altering soil nitrogen availability. These results highlight the need for temporal and functional studies to understand how pathogen suppressive microbial communities assemble and function in ASDtreated soils.
