An agrochemical composition is provided, the composition comprising A) at least one agrochemical active ingredient of 1-arylpyrazoles of formula (I) in which: R1 represents a halogen atom or CN or a methyl group R2 represents S(O)n R3 or 4,5-dicyanoimidazol-2-yl or haloalkyl R3 represents alkyl or haloalkyl R4 represents a hydrogen or halogen atom or NR5 R6, S(O)m R7, C(O)R7 or C(O)OR7, alkyl, haloalkyl or OR8 or –N=C(R9)(R10) radical R5 and R6 independently represent a hydrogen atom or alkyl, haloalkyl, C(O)alkyl, C(O)OR7 or S(O)r CF3 radical or R5 and R6 can together form a divalent alkylene radical which can be interrupted by one or two divalent heteroatoms, such as oxygen, nitrogen or sulphur R7 represents alkyl or haloalkyl R8 represents alkyl or haloalkyl or a hydrogen atom R9 represents alkyl or a hydrogen atom R10 represents a phenyl or heteroaryl group optionally substituted by one or more halogen atoms or groups such as OH, –O-alkyl, –S-alkyl, CN or alkyl R11 and R12 represent, independently of one another, a hydrogen or halogen atom or CN or NO2 R13 represents a halogen atom or a haloalkyl, haloalkoxy, S(O)q CF3 or SF5 group m, n, q and r represent, independently of one another, an integer equal to 0, 1 or 2 X represents a trivalent nitrogen atom or a C–R12 radical, the other three valencies of the carbon atom forming part of the aromatic ring with the proviso that, when R1 is methyl, then either R3 is haloalkyl, R4 is NH2, R11 is Cl, R13 is CF3 and X is N or else R2 is 4,5-dicyanoimidazol-2-yl, R4 is Cl, R11 is Cl, R13 is CF3 and X is C–Cl and B) one or more adhesion promoters comprising a polyether the said polyether containing at least 16 polyoxyethylene and/or polyoxypropylene moieties or one or more adhesion promoters comprising a polyether having a chain of ethylene oxide (EO) units and a hydrophobic portion, in which the ratio of the number of ethylene oxide (EO) units to the length of the hydrophobic portion of the polyether molecule is at least
