[0383] In this test, the samples which had been treated with 31 ppm of the active substance from examples Ex-6, Ex-17, Ex-18, Ex-19, Ex-20, Ex-23, Ex-24, Ex-26, Ex-28, Ex-29, Ex-30, Ex-31, Ex-32, Ex-33, Ex-34, Ex-35, Ex-36, Ex-44, Ex-45, Ex-46, Ex-47, Ex-48, Ex-49, Ex-51, Ex-52, Ex-54, Ex-55, Ex-57 respectively, showed unto 8% growth of the pathogen.

[0384] The measured parameters were compared to the growth of the active compound-free control variant (100%) and the fungus-free blank value to determine the relative growth in % of the pathogens in the respective active compounds.

Green House

[0385] The compound was dissolved in a mixture of acetone and/or dimethylsulfoxide and the wetting agent/emulsifier Wettol, which is based on ethoxylated alkylphenoles, in a ratio (volume) solventemulsifier of 99 to 1 to give a total volume of 5 ml. Subsequently, water was added to total volume of 100 ml.

[0386] This stock solution was then diluted with the described solvent-emulsifier-water mixture to the final concentration given in the table below.

Example 14Preventative Fungicidal Control of Botrytis cinerea on Leaves of Green Pepper

Then the plants were immediately transferred to a humid chamber. After 5 days at 22 to 24? C. and a saturated relative humidity, the extent of fungal attack on the leaves was visually assessed as % diseased leaf area.

[0390] In this test, the samples which had been treated with 250 ppm of the active substance from examples from Ex-3, Ex-5, Ex-7, Ex-8 respectively, showed up to at most 16% growth of the pathogen whereas the untreated plants were 90% infected.

[0391] Young seedlings of soybeans were grown in pots. These plants were sprayed to run-off with previously described spray solution, containing the concentration of active ingredient or mixture mentioned in the table below. The next day the treated plants were inoculated with a biomalt suspension, containing the mycelium of Sclerotinia sclerotiorum. Then the trial plants were cultivated for 6 days in a greenhouse chamber at 23? C. and a relative humidity between 80 and 85%. The extent of fungal attack on the leaves was visually assessed as % diseased leaf area.
