1. A composition comprising by weight: (i) from 2% to 90% of a herbicidal sulfonylurea water soluble salt, wherein the sulfonylurea is selected from the group consisting of amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, cinosulfuron, cyclosulfamuron, ethametsulfuron-methyl, ethoxysulfuron, flupyrsulfuron-methyl, flazasulfuron, flucetosulfuron, foramsulfuron, halosulfuron-methyl, imazosulfuron, iodosulfuron-methyl, mesosulfuron-methyl, metsulfuron-methyl, oxasulfuron, primisulfuron-methyl, prosulfuron, pyrazosulfuron-ethyl, rimsulfuron, sulfometuron-methyl, sulfosulfuron, thifensulfuron-methyl, triasulfuron, triflusulfuron-methyl, and tritosulfuron;(ii) from 1% to 50% ethanolamine, wherein the composition having ethanolamine improves spray equipment clean-out and reduces residual sulfonylurea herbicide contamination left in the spray material in comparison to the composition without the ethanolamine;(iii) from 0-95% of one or more additional formulating ingredients;a sum of all the ingredients in the composition totaling 100%; andwherein a weight ratio of the sulfonylurea water soluble salt to the ethanolamine is from 1:90 to 90:1. 2. The composition of claim 1, wherein the sulfonylurea is selected from the group consisting of: metsulfuron-methyl, sulfometuron-methyl, rimsulfuron, thifensulfuron-methyl, chlorsulfuron, flupyrsulfuron-methyl, pyrazosulfuron-ethyl, ethametsulfuron-methyl, bensulfuron methyl, mesosulfuron-methyl, chlorimuron-ethyl, azimsulfuron, and triflusulfuron-methyl. 3. A method for reducing residual sulfonylurea pesticide contamination of a spray tank from which the sulfonylurea is applied, comprising the steps: (a) formulating the sulfonylurea as an agriculturally suitable water soluble salt;(b) preparing a composition comprising by weight: from 2% to 90% sulfonylurea water soluble salt, wherein the sulfonylurea is selected from the group consisting of amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, cinosulfuron, cyclosulfamuron, ethametsulfuron-methyl, ethoxysulfuron, flupyrsulfuron-methyl, flazasulfuron, flucetosulfuron, foramsulfuron, halosulfuron-methyl, imazosulfuron, iodosulfuron-methyl, mesosulfuron-methyl, metsulfuron-methyl, oxasulfuron, primisulfuron-methyl, prosulfuron, pyrazosulfuron-ethyl, rimsulfuron, sulfometuron-methyl, sulfosulfuron, thifensulfuron-methyl, triasulfuron, triflusulfuron-methyl, and tritosulfuron;(ii) from 1% to 50% ethanolamine, wherein the composition having ethanolamine improves spray equipment clean-out and reduces residual sulfonylurea herbicide contamination left in the spray material in comparison to the composition without the ethanolamine;(iii) from 0-95% of one or more additional formulating ingredients;a sum of all the ingredients in the composition totaling 100%; andwherein a weight ratio of the sulfonylurea water soluble salt to the ethanolamine is from 1:90 to 90:1;(c) applying the sulfonylurea salt composition to a crop while minimizing buildup of insoluble sulfonylurea in the spray tank, and(d) rinsing the spray tank substantially free of the residual sulfonylurea after application. 4. The method of claim 3, wherein the sulfonylurea salt is employed in the absence of a tank mix partner. 5. The method of claim 3, wherein the sulfonylurea salt is employed in the presence of a tank mix partner.
