These compounds are useful as Adjuvants in Agrochemical formulations, in particular combined formulations of herbicides that have different effects of weed control, notably non Selective herbicide and herbicide Selective herbicide Selective； in particular, in particular herbi CIDA Selective Broadleaf and graminicide； and graminicide Selective and non Selective herbicide,A combination of a non Selective herbicide, soluble in water, with a selective herbicide glyphosate type (type clethodim graminicide), in particular, to reduce or eliminate the antagonism between different types of herbicide.Formulations containing such combinations of herbicide adjuvants and the compounds are particularly useful in the control of Weeds including Volunteer glyphosate resistant Corn grown after soybean resistant to glyphosate.Claim 1: a compound or mixture of compounds is / are mono - ester (S) Ethoxylated sorbitan Fatty Acid in which the carbon chain length of the Fatty Acid is from 8 to 14 and the overall degree of ethoxylation is average from 7 to 16.Claim 2: a compound or mixture of compounds according to claim 1, wherein the ester () (IS) are compounds of formula: (eon1r1 Sorb -) (eon2r2) (eon3r3) (where eon4r4)； (i) Sorb represents a residue obtained by the Elimination of four hydroxyl H Atoms the sorbita No； (ii) eo represents a residue of etilenoxi； (iii) N1, N2, N3,N4 and each independently represent average values from 0 to 10； (iv) the total N1 + N2 + n3 + N4 has an average value from 7 to 16； and (V) R1, R2, R3 and R4 each independently represents H or an acyl Group - C (o) - R5 where R5 is a hidrocarbonilo C7 - 13.Estos compuestos son útiles como adyuvantes en formulaciones agroquímicas, en particular formulaciones combinadas de herbicidas que tienen diferentes efectos de control de malezas, notablemente de herbicida no selectivo y herbicida selectivo； en particular herbicida selectivo, en particular herbicida selectivo de hojas anchas, y graminicida； y graminicida selec
