  abstract = {{M}itigation of pesticide dispersion in soil and water is required to protect ecosystem health and the anthropic uses of water bodies. {B}iochar amendments have been suggested to reduce pesticide dispersion due to their high sorption potentials. {N}evertheless, appraisals at different scales have been limited by the costs of pesticide analyses. {T}he aim of this study was to evaluate the potential of two fluorescent tracers, uranine ({UR}) and sulforhodamine {B} ({SRB}), for use as pesticide proxies in the context of biochar amendments used for mitigation purposes. {T}herefore, we compared the sorption processes of both fluorescent tracers and those of three pesticides, glyphosate, 2,4-{D}, and difenoconazole for soils; three wood biochars (pine, oak, and beech/charm blend); and soil/biochar mixtures representing agricultural usages. {T}he results showed that the sorption of glyphosate by soil was unaffected by amendment with the tested pine, oak, and wood blend biochars. {I}n contrast, the sorption coefficients of {UR}, {SRB}, 2,4-{D}, and difenoconazole were significantly increased with these biochar amendments. {SRB}, in particular, exhibited sorption behavior similar to that of the hydrophobic fungicide difenoconazole. {T}his indicates promise for the use of {SRB} as a proxy for hydrophobic pesticides, in testing biochar amendments.},
