Benzoic acid (BA) reduced the ratio of bacteria to fungi in the soil. BA changed the abundance of Fusarium, Trichoderma, Metarhizium and Burkholderia. BA promoted the growth of the peanut root rot pathogen Fusarium sp. in vitro. BA supplementation altered the Burkholderia species composition. Effects of BA in the soil were reflected by soil microbial populations.
