A method of preparing an aqueous tank mixture composition comprising a glyphosate component and a dicamba component, the method comprising: combining an aqueous composition of glyphosate concentrate, a dicamba composition comprising one or more dicamba salts and dilution water to form the composition of the tank mixture, wherein the glyphosate concentrate composition comprises a glyphosate salt selected from the group consisting of the monoethanolamine salt, the potassium salt, and mixtures thereof at a glyphosate loading of at least 240 grams of acid equivalent per liter (g ae / l) and one or more surfactants and wherein the pH of a 5 wt% acid equivalent dilution of the glyphosate concentrate composition is 5 to 6.5 and wherein the molar ratio of the glyphosate-glyphosate neutralizing base used to prepare the glyphosate concentrate composition is from 1.25: 1 to 1.5: 1, and wherein the surfactant is selected from the group consisting of: (1) a quaternary ammonium salt of formula (I): ** Formula wherein R 1 is hydrocarbyl or substituted hydrocarbyl having from 1 to 30 carbon atoms ； R2 in each of the groups (R2O) x and (R2O) and is independently C2-C4 alkylene； R3 is hydrogen, or a linear or branched alkyl group having from 1 to 4 carbon atoms； R4 is hydrocarbyl or substituted hydrocarbyl having from 1 to 30 carbon atoms； x and y are independently an average number from 1 to 40； and X- is an acceptable anion in agricultural uses； (2) an alkoxylated tertiary etheramine of formula (II): ** Formula ** wherein R5 is a hydrocarbyl or substituted hydrocarbyl having from 4 to 22 carbon atoms； R6 and R7 are each independently a hydrocarbylene having 2, 3 or 4 carbon atoms； each R 8 is independently hydrogen or C 1-6 alkyl, m is an average number from 1 to 10； and the sum of x and y is an average value that varies from 2 to 60； (3) an alkylpolysaccharide of formula (III): wherein R9 is a substituted or unsubstituted straight or branched chain hydrocarbyl selected from alkyl,
