1. Characteristic 1: a method for reducing spray drift in the application of an underwater herbicide spray mixture, including adding a concentration of an underwater herbicide to an underwater spray mixture with a weight percentage of 0.1% to 20%. About formula (1) or formula (2),where R¹ represents a saturated or unsaturated linear or branched C₁₋₈ alkyl or a saturated or unsaturated straight or branched C hetero heteroalkyl, R² and R³ independently represent hydrogen, hydroxyl, a straight or branched C₁₋₆ alkyl saturated or unsaturated, or a C₁₋₉ straight or branched chain saturated or unsaturated ester, R⁴ represents a saturated or unsaturated linear or branched C₁₋₈ alkyl or a saturated or unsaturated straight or branched C₄₋₁₂ heteroalkyl, and R⁵ and R⁶ independently represent hydrogen,hydroxyl or a saturated or unsaturated straight or branched C₁₋₆ alkyl； between 20 and 60% by weight (base ae) of at least one auxinic herbicide； and between 0 and 10% by weight of surfactant, where the aqueous herbicide concentrate is a transparent and homogeneous liquid and forms an emulsion when water is added. Claim 2: The method of claim 1, wherein the aromatic ester is methyl salicylate, ethyl benzoate, propyl benzoate, tetrahydrofurfuryl benzoate, or mixtures thereof. Claim 3: The method of any one of claims 1-2, wherein the auxinic herbicide is a water soluble salt of 2,4-D, a water soluble tricyclopyr salt,A water-soluble dicamba salt or mixture thereof Claim 7: the method of claims 1-6, i.e. the mixture of water herbicide sprayers also includes glyphosate and one or more surfaces selected to increase glyphosate herbicide activity. 11. Claim 11: composition of a water herbicide concentrate containing Lor following: between 0.1 and 20% by weight of one or more aromatic esters of the formula (1) or (2) where R¹ represents a saturated or unsaturated straight or branched chain C₁₋₈ alkyl or a C₄₋₁₂ heteroalkyl linear or branched chain saturated or unsaturatedR² and R³ indepe
