Kinetic aspects and identification of by-products during the ozonation of bitertanol in agricultural wastewaters

► Bitertanol was easily degraded by ozonation in aqueous solutions. ► Reaction kinetic orders were determined as one for bitertanol and one for ozone. ► Kinetic rate constants appeared to be lower in diluted seed-loading solution. ► Four main ozonation by-products were identified by LC-ESI(+)-MS.
