Description

BIOLOGICAL EXAMPLES

[0228] The compositions according to the invention are tested for their biological (fungicidal) activity using application rates wherein the component (A) is applied at a rate of from 25 g a.i./ha to 500 g a.i./ha in association with 10 g a.i./ha to 500 g a.i./ha of component (B).

[0229] The compositions according to the invention are tested for their biological (fungicidal) activity as dimethylsulfoxide (DMSO) solutions using one or more of the following protocols (Examples 1-1 and 1-2). A standard description of the liquid culture tests is provided in Example 1.

[0230] Aureobasidin A and its synthesis are known from Takesako et al., The Journal of Antibiotics, 1991, 44, 919-924. Aureobasidin A is separated from the fermentation broth by extraction with ethyl acetate, followed by extraction of the ethyl acetate concentrate with a mixture of MeOH:H.sub.2O (80% by volume) and cyclohexane (20% by volume), and purified by silica gel column chromatography (silica-gel, elution with hexane:ethyl acetate) followed by reverse phase column chromatography (RP18, elution with acetonitrile:H.sub.2O). As already indicated, components (B) of the compositions are known and are commercially available and/or can be prepared using procedures known in the art and/or procedures reported in the literature.

Example 1: Liquid Culture Tests in Well Plates

[0231] Mycelia fragments or conidia suspensions of a fungus, prepared either freshly from liquid cultures of the fungus or from cryogenic storage, are directly mixed into nutrient broth. DMSO solutions of the test compound (max. 10 mg/mL) is diluted with 0.025% Tween20 by factor 50 and 10 μL of this solution is pipetted into a microtiter plate (96-well format). The nutrient broth containing the fungal spores/mycelia fragments is then added to give an end concentration of the tested compound. The test plates are incubated in the dark at 24° C. and 96% relative humidity (rh). The inhibition of fungal growth is determined photometrically and visually after 3-7 days, depending on the pathosystem, and percent antifungal activity relative to the untreated check is calculated.

Example 1-1: Botrytis cinerea (Gray Mould)

[0232] Conidia of the fungus from cryogenic storage were directly mixed into nutrient broth (PDB potato dextrose broth). After placing a DMSO solution of the test compositions into a microtiter plate (96-well format), the nutrient broth containing the fungal spores was added. The test plates were incubated at 24° C. and the inhibition of growth was determined photometrically after 72 hours.

Example 1-2: Alternaria solani (Early Blight of Tomato/Potato)

[0233] Conidia of the fungus from cryogenic storage were directly mixed into nutrient broth (PDB potato dextrose broth). After placing a DMSO solution of the test compositions into a microtiter plate (96-well format) the nutrient broth containing the fungal spores was added. The test plates were incubated at 24° C. and the inhibition of growth was determined photometrically after 48 hours.

Results

[0234] Results from the tests outlined above are shown below in Tables 1 to 18. These data show that synergistic fungicidal activity is observed for the combination of Aureobasidin A and another active ingredient of component (B) against Botrytis cinerea and Alternaria solani at certain weight ratios. According to COLBY, in mathematical terms the synergism factor SF corresponds to O/E. In the agricultural practice an SF of 1.1 indicates significant improvement over the purely complementary addition of activities (expected activity), while an SF of <0.9 in the practical application routine signals a loss of activity compared to the expected activity.
