1. A non-aqueous, emulsifiable concentrate formulation (EC) for herbicidal crop protection active compounds which consists essentially of (a) 25 to 150 g/L of at least one fluorinated herbicidal compound of formula I in which R<1> and R<3> each independently represent a fluorine atom or a fluoroalkyl, group; R<2> represents a hydrogen atom or an optionally substituted alkyl or alkoxy group; and m and n each independently represent an integer from 1 to 2. (b) 400 to 900 g/L of one or more herbicidal alkyl phenoxyalkanoates, (c) 10 to 100 g/L of at least one non-ionic surfactant, (d) 10 to 100 g/L of at least one benzene sulfonate, (e) 50 to 600 g/L of one or more solvent selected from the group consisting of aliphatic or aromatic hydrocarbons, methylated plant oils and water-miscible polar aprotic organic solvents, and (f) optionally, up to 5 g/L of a defoamer. 2. An emulsifiable concentration formulation in accordance with Claim 1 wherein said fluorinated herbicidal compound (a) is N-(4-fluorophenyl)-2-(3-alpha,alpha,alpha-trifluoromethylphenoxy)-6-pyridinecarboxamide. 3. An emulsifiable concentration formulation in accordance with Claim 1 wherein the herbicidal alkyl phenoxyalkanoate (b) is an alkyl phenoxy acetat eof formula II wherein R<4> each independently represents a halogen atom or a C1-6alkyl group, R<5> and R<6> each independently represent a C1-6alkyl group, R<7> represents a hydrogen atom or a methyl group, and t represents an integer from 1 to 3. 5. An emulsifiable concentration formulation in accordance with Claim 1 wherein said non-ionic surfactant (c) is an ethoxylated castor oil. 6. An emulsifiable concentration formulation in accordance with Claim 1 wherein said benzenesulfonate (d) is a sodium or calcium alkyl-benzene sulfonate. 7. An emulsifiable concentration formulation in accordance with Claim 1which consists essentially of (a) 30 to 125 g/L of at least one fluorinated herbicidal compound of formula I; (b) 700 to 875 g/L of one or more herbicidal alkylphenoxyalkanoate of formula II; (c) 20 to 75 g/L of at least one non-ionic surfactant, (d) 20 to 75 g/L of at least one sodium or calcium alkyl-benzene sulfonate, (e) 50 to 200 g/L of one or more solvent selected from the group consisting of aliphatic or aromatic hydrocarbons, methyl C8-12carboxylates, N-methylpyrrolidone, gamma-butyrolactone and isopropyl lactate; and (f) optionally, up to 2 g/L of at least one defoamer selected from the group consisting of polydimethylsiloxanes and perfluoroalkylphosphonic/perfluoroalkylphosphinic acids. 8. A method for the control of undesired weed at a locus which comprises emulsifying the formulation of Claim 1 with water and treating said locus with the obtained diluted aqueous formulation. 9. A formulation consisting essentially of the fluorinated herbicidal Compound (a) according to claim 2 and an alkyl phenoxyalkanoate (b) according to claim 4.
