Preferably, the weight ratio of amberidin A to kasugamycin is 1:125 to 1:250. Preferably, the weight ratio of amberidin A to kasugamycin is 1:125 to 1:2000.

Preferably, the plant pathogenic fungus is selected from the group consisting of *Alternaria solanacea* and *Botrytis cinerea*.

Preferably, the weight ratio of amberidin A to natamycin is from 1:1.2 to 1:19.9. More preferably, the weight ratio of amberidin A to natamycin is from 1:1.2 to 1:9.9.

Preferably, abamin A is applied in combination with natamycin at a ratio of 0.0063 ppm to 0.0125 ppm, preferably wherein the plant pathogenic fungus is *Botrytis cinerea*. Preferably, abamin A is applied in combination with natamycin at a ratio of 0.0063 ppm to 0.025 ppm, preferably wherein the plant pathogenic fungus is *Alternaria solanacea*. Preferably, the plant pathogenic fungus is selected from the group consisting of *Alternaria solanacea* and *Botrytis cinerea*.

[0196] Preferably, the compositions according to the invention comprise an agriculturally acceptable carrier and / or formulation adjuvant and optionally a surfactant. The invention also provides fungicidal compositions comprising synergistically effective amounts of the combination of components A and B as mentioned above, along with an agriculturally acceptable carrier and optionally a surfactant. In said compositions, as described above, the weight ratio of component A to component B is preferably 100:1 to 1:5000, more preferably 100:1 to 1:1000, even more preferably 50:1 to 1:500, and still more preferably 20:1 to 1:200.

[0197] It has been unexpectedly discovered that components A and B in specific weight ratios can produce synergistic activity. Therefore, another aspect of the invention is a composition in which components A and B are present in an amount that produces a synergistic effect. This synergistic activity is evident from the fact that the fungicidal activity of a composition containing components A and B is greater than the sum of the fungicidal activities of components A and B. This synergistic activity expands the scope of action of components A and B in two ways. First, by reducing the application ratio of components A and B while maintaining the same level of effectiveness, this means that even if the two individual components become completely ineffective at such low application ratios, the mixture of active ingredients still achieves a high degree of plant pathogen control. Second, the spectrum of controllable plant pathogens is significantly broadened.

[0198] Synergistic effects exist when the combined effect of active ingredients is greater than the sum of the effects of the individual components. For a given combination of active ingredients, the expected effect E follows the so-called Colby formula and can be calculated as follows (COLBY, SR, “Calculating synergistic and antagonistic responses of herbicide combination”, Weeds, Vol. 15, pp. 20-22; 1967):

[0199] ppm = the number of milligrams of active ingredient (= ai) per liter of spray mixture.

[0200] X = % effect of active ingredient (A) using p ppm.

[0201] Y = % effect of active ingredient (B) using q ppm of active ingredient.

[0202] According to Colby, using p + q ppm of active ingredients, the expected (additive) effect of active ingredient (A) + (B) is

[0203] If the observed effect (O) is greater than the expected effect (E), then the combined effect is superadditive, i.e., synergistic. Mathematically, synergism corresponds to a positive value of the difference (OE). In the case of purely complementary additive activity (expected activity), the difference (OE) is zero. A negative value of the difference (OE) signifies a loss of activity compared to the expected activity.

[0204] However, in addition to the actual synergistic effect relative to the fungicidal activity, the compositions according to the invention may also have other unexpectedly advantageous properties. Examples of such advantageous properties that may be mentioned are: more favorable biodegradability; improved toxicological and / or ecotoxicological behavior; or improved characteristics of useful plants, including: emergence, crop yield, more developed root system, increased tillering, increased plant height, larger leaves, less basal leaf mortality, stronger tillering, greener leaf color, less fertilizer required, less seed required, more tillering, earlier flowering, earlier grain maturity, less lodging, enhanced bud growth, improved plant vigor, and earlier germination.

[0205] The composition according to the invention is preferably in a synergistically effective amount. Preferably, component A and component B of the composition according to the invention are each in an amount that produces a synergistic effect, preferably a synergistic fungicidal effect. Preferably, the composition according to the invention has a weight ratio of component A to component B in a synergistically effective amount.

[0206] It has been found that kasugamycin or natamycin, when combined with cyclic ester peptides represented by formula (I), particularly AbA, advantageously provide more than additive antifungal activity. See the following examples, which disclose the synergistic antifungal activity of AbA and kasugamycin or natamycin.

[0207] The following examples are provided to illustrate the invention and are not intended to limit the invention in any way.

[0208] Biological examples

[0209] The biological (fungal) activity of the compositions according to the invention in the form of dimethyl sulfoxide (DMSO) solutions was tested using one or more of the following methods (Examples 1-1 and 1-2).

[0210] Amoxicillin A and its synthesis are known from Takesako et al., The Journal of Antibiotics, 1991, 44, 919-924. Amoxicillin A was separated from the fermentation broth by extraction with ethyl acetate, followed by extraction of the ethyl acetate concentrate with a mixture of MeOH:H2O (80% by volume) and cyclohexane (20% by volume), and purified by silica gel column chromatography (silica gel, eluted with hexane:ethyl acetate) followed by reversed-phase column chromatography (RP18, eluted with acetonitrile:H2O). As already noted, amoxicillin and natamycin are known and commercially available and / or can be prepared using procedures known in the art and / or procedures reported in the literature.

[0211] Example 1-1: Botryotinia fuckeliana (gray mold);

[0212] Frozen fungal conidia were directly mixed into nutrient liquid medium (Vogel's liquid medium). Nutrient liquid medium containing fungal conidia was added after placing a (DMSO) solution or (aqueous) suspension of the test compound into a microtiter plate (96-well size). The test plate was incubated at 24°C, and inhibition of growth was determined by photometry and visual inspection after 72 hours.

[0213] Example 1-2: Alternaria alternata (early blight of tomato / potato)

[0214] Frozen fungal conidia were directly mixed into nutrient liquid medium (PDB: Potato Dextrose Liquid Medium). After placing a (DMSO) solution or (aqueous) suspension of the test compound into a microtiter plate (96-well size), nutrient liquid medium containing fungal conidia was added. The test plate was incubated at 24°C, and inhibition of growth was determined by photometry and visual inspection after 48 hours.

[0215] result

[0216] The results of the tests summarized above are shown in Tables 1 through 4 below. These data show that synergistic fungicidal activity against *Botrytis cinerea* and *Alternaria solanacearum* was observed for specific weight ratios of abamectin A combined with either kasugamycin or natamycin. According to Colby, mathematically, the synergistic factor SF corresponds to O / E. In agricultural practice, an SF ≥ 1.1 indicates a significant improvement in activity relative to a purely complementary additive effect (the expected activity), while in practical application practices, an SF ≤ 0.9 signifies a loss of activity compared to the expected activity.
