1. An agrochemical formulation, comprising:
i) a first adjuvant, where the first adjuvant is a fatty ester of an oligomer of glycerol having from 2 to 3 repeat units represented by formula (I):
P.[R1]m  (I)
wherein:
P is the residue of an oligomer of glycerol having from 2 to 3 repeat units and having m active hydrogen atoms;
m is an integer of 3 to 5;
each R1 is independently hydrogen, C8 to C12 alkyl, C16 to C20 alkenyl or an alkanoyl group represented by —C(O)R2, where at least one R1 is an alkanoyl group represented by —C(O)R2;
wherein the alkanoyl group represented by —C(O)R2 is a residue of a C16 to C22 fatty acid;
ii) a co-adjuvant, wherein the co-adjuvant is an alkoxylated alcohol represented by the formula (II):
R3—O-(AO)x—H  (II)
wherein
R3 is the residue of a fatty alcohol selected from capric alcohol, lauryl alcohol, myristyl alcohol;
each AO is, independently, an oxyethylene (EO) group or an oxypropylene (PO) group; and
x represents an integer in the range from 4 to 7; and
iii) at least one agrochemical active,
wherein:
the contact angle of the agrochemical formulation is less than 40°;
the surface tension of the agrochemical formulation is less than 32 mN/m; and
the viscosity range of the agrochemical formulation is 30 to 60 mPa·s.
