[0065] CLAIMS 1. Use of a composition comprising choline salts of C5-C13 fatty acids as a fungicide.
[0066] 2. Use according to statement 1, wherein the composition is an aqueous composition comprising choline salts of C5-C13 fatty acids.
[0067] 3. Use according to statement 1 or 2, wherein the composition is formulated as a spray or sprayable liquid, or as a concentrate.
[0068] 4. Use according to any one of statements 1 to 3, wherein the composition comprises 0.01% (w / v) to 70% (w / v) of choline salts of C5-C13 fatty acids.
[0069] 5. Use according to statement 4, wherein the composition is a concentrate comprising 5% (w / v) to 70% (w / v) of choline salts of C5-C13 fatty acids, preferably 10% (w / v) to 60% (w / v) choline salts of C5-C13 fatty acids.
[0070]6. The use according to statement 4, wherein the composition is a sprayable liquid comprising 0.01% (w / v) to 5% (w / v) of choline salts of C5-C13 fatty acids , preferably 0.05% (w / v) to 2% (w / v) of choline salts of C5...
Embodiment 1
[0090] Example 1: Study of Phytotoxicity of Compositions Containing Nonanoic Choline on Lettuce Plants
[0091] Purpose. The purpose of this experiment was to evaluate the phytotoxicity of a mixture of pelargonic acid (also known as PLA) and choline hydroxide on lettuce plants in order to assess the extent to which its phytotoxic effect could be neutralized by mixing pelargonic acid with choline hydroxide. Furthermore, a specific objective was to evaluate the potential efficacy of this choline-nonanoate as a fungicide without inducing any phytotoxicity on crops.
[0092] process. Based on the titration curve ( figure 1 ), using nonanoic acid (>97%) and choline hydroxide (45%) for neutralization. Based on the titration curve, nonanoic acid choline (29.1% PLA (>97%) and 40.4% choline hydroxide (45%)) was prepared by mixing 14.55 mL of nonanoic acid with 15.25 mL of distilled water followed by the addition of 20.2 mL of choline hydroxide stock solution. The nonanoic acid c...

[0101] Example 2: Evaluation of the use of a composition comprising choline nonanoate as a fungicide according to one embodiment of the invention
[0102] Purpose. The purpose of this experiment was to evaluate the efficacy of compositions comprising choline nonanoate against some selected pathogenic bacteria in vitro.
[0103] process. The strains used in this experiment (Table 3) were maintained and refreshed on Potato Dextrose Agar (PDA) at 25°C.
[0104] Table 3: Pathogenic bacteria used in embodiment 3
[0105] pathogenic bacteria crop separated country Potato anthracnose (Colletotrichum coccodes) potato Netherlands Botrytis cinerea lettuce Belgium Alternaria solani potato Netherlands Fusarium graminearum wheat Belgium Botrytis cinerea grape vines Italy
[0106] In the first setup, the test compositions were added directly to the PDA (approximately 20 mL / dish) (Table 4). An agar plug (8 mm in diameter) f...
