  • the potassium phoshite buffer was used as commercial ready-mix of mono- potassium salt and di-potassium salt of phosphorous acid (KHP) in water (Canon, Luxembourg Industries Ltd., Israel) at a concentration of about 755 g equivalent to 504 g phosphorous acid (H3PO3) equivalents per liter.
  • the pH was adjusted to pH 4 or 5 with phosphoric acid (H3PO4).
  • H3PO4 phosphoric acid
  • the diseases were converted into efficacies.
  • An efficacy of 0 means that the infection level of the treated plants corresponds to that of the untreated control plants; an efficacy of 100 means that the treated plants were not infected.
  • Grape cuttings were grown in pots to the 4 to 5 leaf stage. These plants were sprayed to run-off with an aqueous suspension, containing the concentration of active ingredient or their mixture mentioned in the table below.
  • the plants were allowed to air-dry. The next day they were inoculated with an aqueous spore suspension of Plasmopara viticola by spraying it at the lower leaf-side.
  • the trial plants were immediately transferred for 24 h to a humid chamber with 22 to 24°C and a relative humidity close to 100%. For a period of 5 days, cultivation followed in a greenhouse at 20 to 25°C and a relative humidity about 50 to 80%. To stimulate the outbreak of the disease symptoms, the plants were transferred to a humid chamber again for 24 hours. Then the extent of fungal attack on the lower leaf surface was visually assessed as % diseased leaf area.
  • Example 2 Fungicidal control (7 day preventative) of grape downy mildew caused by Plasmopara viticola Grape cuttings were grown in pots to the 4 to 5 leaf stage. These plants were sprayed to run-off with an aqueous suspension, containing the concentration of active ingredient or their mixture mentioned in the table below.
  • the plants were allowed to air-dry and cultivated in a greenhouse for one week. Then they were inoculated with an aqueous spore suspension of Plasmopara viticola by spraying it at the lower leaf-side. Then the trial plants were immediately transferred for 24 h to a humid chamber with 22 to 24°C and a relative humidity close to 100%. For a period of 5 days, cultivation followed in a greenhouse at 20 to 25°C and a relative humidity about 50 to 80%. To stimulate the outbreak of the disease symptoms, the plants were transferred to a humid chamber again for 24 hours. Then the extent of fungal attack on the lower leaf surface was visually assessed as % diseased leaf area.
