Claim 0:
1. An aqueous herbicidal concentrate solution comprising:
(a) a glyphosate component comprising a salt of glyphosate in a concentration greater than 300 grams acid equivalent per liter, wherein the glyphosate component does not contain the isopropylamine salt of glyphosate, the n-propylamine salt of glyphosate or a combination thereof;
(b) an amidoalkylamine surfactant of structure (I):, , wherein R1 is hydrocarbyl or substituted hydrocarbyl having from 1 to about 22 carbon atoms, R2 and R3, are each independently hydrocarbyl or substituted hydrocarbyl having from 1 to about 6 carbon atoms, and R4 is hydrocarbylene having from 1 to about 6 carbon atoms; and
(c) at least one co-surfactant comprising an alkoxylated tertiary amine, an alkoxylated quaternary amine, an alkoxylated tertiary etheramine, an alkoxylated quaternary etheramine, an alkoxylated etheramine oxide, an alkoxylated alcohol, a phosphate ester of alkoxylated alcohol, or a combination thereof;
wherein the alkoxylated tertiary amine surfactant is of structure (II):, , wherein R1 is hydrocarbyl or substituted hydrocarbyl having from about 4 to about 22 carbon atoms, R2 and R3 are each independently hydrocarbylene having 2, 3, or 4 carbon atoms, and the sum of x and y is an average value ranging from about 2 to about 50;

wherein the alkoxylated tertiary etheramine surfactant is of structure (IV):, , wherein R1 is hydrocarbyl or substituted hydrocarbyl having from about 4 to about 22 carbon atoms; R2, R3 and R4 are each independently hydrocarbylene having 2, 3, or 4 carbon atoms; m is an average number from about 1 to about 10; and the sum of x and y is an average value ranging from about 2 to about 60;
wherein the alkoxylated quaternary etheramine surfactant is of structure (V):, , wherein R1 is hydrocarbyl or substituted hydrocarbyl having from about 4 to about 22 carbon atoms; R2, R3 and R4 are each independently a hydrocarbylene having 2, 3, or 4 carbon atoms; m is an average number from about 1 to about 10; the sum of x and y is an average value ranging from about 2 to about 60; R5 is hydrocarbyl or substituted hydrocarbyl having from 1 to about 4 carbon atoms; and A is a charge balancing counter-anion;
wherein the alkoxylated etheramine oxide surfactant is of structure (VI):, , wherein R1 is hydrocarbyl or substituted hydrocarbyl having from about 4 to about 22 carbon atoms; R2, R3 and R4 are each independently hydrocarbylene having 2, 3, or 4 carbon atoms; m is an average number from about 1 to about 10; and the sum of x and y is an average value ranging from about 2 to about 60;
wherein the alkoxylated alcohol surfactant is of structure (VIII):

R1—O—(R2O)nH  Structure (VIII), wherein R1 is hydrocarbyl or substituted hydrocarbyl having from about 4 to about 22 carbon atoms; R2 is hydrocarbylene having 2, 3, or 4 carbon atoms; n is an average value ranging from about 2 to about 50; and
wherein the phosphate ester of alkoxylated alcohol surfactant is of structure (XIa) or (XIb):, wherein each R1 is independently hydrocarbyl or substituted hydrocarbyl having from about 4 to about 22 carbon atoms; each R2 is independently hydrocarbylene having 2, 3, or 4 carbon atoms; each m is independently an average number from about 1 to about 60; and R3 and R4 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl having from 1 to about 6 carbon atoms;
wherein a carbon chain atom of the substituted hydrocarbyl is substituted with a heteroatom selected from the group consisting of nitrogen, oxygen, silicon, phosphorous, boron, sulfur and halogen atom and/or the substituted hydrocarbyl is substituted with a substituent selected from the group consisting of halogen, heterocyclo, alkoxy, alkenoxy, alkynoxy, aryloxy, hydroxy, protected hydroxy, ketal, acyl, acyloxy, nitro, amino, amido, cyano, thiol, acetal, sulfoxide, ester, thioester, ether, thioether, hydroxyalkyl, urea, guanidine, amidine, phosphate, amine oxide, quaternary ammonium salt, and combinations thereof; and
