Use of diaminomethanal carboxylic acid complexes as agricultural spray adjuvants

A spray adjuvant composition comprising a composition consisting essentially of water and diaminomethanal complexes with C1 to C3 carboxylic acids wherein the concentration of carboxylic acid is from 30%-20% by weight based on the combination of carboxylic acid and diaminomethanal and the concentration of diaminomethanal is from 70%-80% by weight based on the combination of carboxylic acid and diaminomethanal and a fatty amine alkoxylate surfactant present in an amount from 5 to 50% by weight and wherein the fatty amine alkoxylate surfactant is selected from the formula:

• wherein R is an alkyl group containing from 8 to 22 carbon atoms and moles of alkoxylation (m+n) are 5-20.
