  • Compound No. 38 of Table I of EP-A1-0381330 has the structure:
  • Alkyl may be straight or branched chain and is, for example, methyl.
  • Halogen is preferably fluorine or chlorine. It is preferred that R is chlorine.
  • the process of the present invention is preferably carried out in a solvent.
  • Preferred solvents include alcohols (especially methanol), polar solvents (such as acetonitrile, N,N- dimethylforrnamide or N-methylpyrrolidone), hydrocarbons (such as toluene or xylene) or ethers (such as tetrahydrofuran or 1 ,2-dimethoxy ethane).
  • the process is preferably carried out at a temperature in the range 20-120°C (such as in the range 20-100°C, especially 20-80°C).
  • the present invention provides a fungicidal composition
  • a fungicidal composition comprising as a first active ingredient Compound A; as a second active ingredient, kresoxim- methyl, azoxystrobin or fluazinam; and a suitable carrier or diluent.
  • the present invention provides a fungicidal composition
  • a fungicidal composition comprising as a first active ingredient Compound A; as a second active ingredient, kresoxim-methyl or azoxystrobin; and a suitable carrier or diluent.
  • the present invention provides a fungicidal composition as described above wherein the weight ratio of the first : second active ingredient is in the range 1 : 10 to 10:1 (especially in the range 1 :7 to 2:1, for example in the range 1 :4 to 2:1).
  • the compositions of the invention are fungicidally active and can be used to control one or more of the following pathogens:

  • a composition as hereinbefore defined.
  • the type of composition used in any instance will depend upon the particular purpose envisaged.
  • compositions for dressing seed may include an agent (for example, a mineral oil) for assisting the adhesion of the composition to the seed; alternatively the active ingredients can be formulated for seed dressing purposes using an organic solvent (for example, N-methylpyrrolidone, propylene glycol or N,N-dimethylformamide).

The mixture may then be ground to a fine powder. Similar compositions may also be granulated to form water-soluble granules. Solutions may be prepared by dissolving the active ingredients in polar solvents such as ketones, alcohols and glycol ethers. These solutions may contain surface active agents to improve water dilution and prevent crystallisation in a spray tank.
  • Aqueous suspension concentrates of largely insoluble solids may be prepared by ball or bead milling with a dispersing agent with a suspending agent included to stop the solid settling.

  • Compositions comprising only granules of fertiliser incorporating, for example coated with, the active ingredients are preferred. Such granules suitably contain up to 25% by weight of active ingredient.
  • aqueous preparations may contain varying amounts of the active ingredients depending upon the intended purpose, but an aqueous preparation containing 0.0001 to 10%), for example 0.005 to 10%), by weight of active ingredients may be used.
  • compositions of this invention may contain other compounds having biological activity, for example compounds having similar or complementary fungicidal activity or which possess plant growth regulating, herbicidal or insecticidal activity.
  • the required quantity of soluble powder containing Compound A is dispersed in water (half the total volume that will be used to spray) in a spray tank.
  • the required quantity of suspension concentrate containing azoxystrobin is then added to the mixture in the spray tank.
  • water is added to makeup the spray solution to the correct volume. The content of the spray tank is agitated throughout the mixing process.
