Suitable active substances can also be granulated in the fashion which is conventional for the production of fertilizer granules, if desired as a mixture with fertilizers.
  • Water-dispersible granules are generally prepared by customary methods such as spray drying, fluidized-bed granulation, disk granulation, mixing with high-speed stirrers and extrusion without solid inert material.

  • Formulations in the form of dusts comprise 1 to 30% by weight of active substance, preferably in most cases 5 to 20% by weight of active substance, and sprayable solutions comprise approximately 0.05 to 80, preferably 2 to 50% by weight of active substance.
  • the active substance content depends partly on whether the active compound is in liquid or solid form and on the granulation auxiliaries, fillers and the like which are being used.
  • the active substance content is between 1 and 95% by weight, preferably between 10 and 80% by weight.
  • the active substance formulations mentioned comprise, if appropriate, the auxiliaries which are conventional in each case, such as stickers, wetters, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents, solvents, fillers, carriers, colorants, antifoams, evaporation inhibitors, and pH and viscosity regulators.

  • Active substances which can be employed in combination with the active substances according to the invention in mixed formulations or in the tank mix are, for example, known active substances as are described, for example, in Weed Research 26, 441-445 (1986) or “The Pesticide Manual”, 11th edition, The British Crop Protection Council and the Royal Soc. of Chemistry, 1997 and literature cited therein.
  • Herbicides which must be mentioned, and can be combined with the compounds of the formula (I) are, for example, the following active substances (note: the compounds are either designated by the common name according to the International Organization for Standardization (ISO) or using the chemical name, if appropriate together with a customary code number):
  • the formulations which are present in commercially available form, are diluted in the customary manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules. Preparations in the form of dusts, soil granules, granules for spreading and sprayable solutions are usually not diluted any further with other inert substances prior to use.
  • the application rate required of the compounds of the formula (I) varies with the external conditions such as, inter alia, temperature, humidity and the nature of the herbicide used. It can vary within wide limits, for example between 0.001 and 1.0 kg/ha or more of active substance, but it is preferably between 0.005 and 750 g/ha.
  • Step 3 2-(2-Chloro-3-(3-tetrahydrofuranyl)oxymethyl-4-methylsulfonylbenzoyl)-cyclohexane-1,3-dione
  • the aquoeus solution was then acidified with 2N HCl and extracted with 2 ⁇ 50 ml of EA. The solution was washed with NaHCO 3 solution. The organic solution was dried with MgSO 4 , filtered and concentrated using a rotary evaporator. The product slowly crystallized out from the concentrated solution. The solid was filtered off with suction and washed with cold EA. This gave 6.81 g (15.9 mmol) of product of a purity of 99.8% according to HPLC and a melting point of 126° C. The yield was 85%.
