Short-term responses of plant growth-promoting bacterial community to the herbicides imazethapyr and flumioxazin

Study of the Biochemical Activity and Plant Growth Promoting Bacteria in Soils Polluted with Oxyfluorfen

“…In addition, these authors observed that the addition of oxyfluorfen increases the nitrogen-fixing capacity by bacteria and the nitrogen availability in soils. Similar results were founded in soils affected by imazethapyr and flumioxazin and in this study, the increase in this activity was related to the increase in the relative abundance of the genus Bradyrhizobium (Araujo et al, 2023). Several authors proposed that the degradation pathway for oxyfluorfen by bacteria implicates a reduction of nitro group to an amino group and some of the metabolites produced after degradation were rich in nitrogen (4-nitrobenzene-1, 3-diol, 4-amino-3-ethoxyphenol, N-(2-ethoxy-4-hydroxyphenyl) acetamide, 3-ethoxy-a-nitrophenol, among others) (Castillo Diaz et al, 2016;Zhao et al, 2016).…”
