The present invention relates to novel N-[2-(2-pyridinyl)ethyl]carboxamides derivatives, their process of preparation, their use as fungicides, particularly in the form of fungicidal compositions, and methods for the control of phytopathogenic fungi of plants using these compounds or their compositions.


The international patent application WO 01/11965 discloses a broad family of fungicidal compounds which generically covers the compounds according to the present invention. Nevertheless, the compounds according to the present invention are not specifically disclosed in this document and their activity as fungicides has not been tested.


It is always of high-interest in agriculture to use pesticidal compounds more active than the compounds already known by the man ordinary skilled in the art in order to decrease the quantity of active ingredient used by the farmer as to maintain an efficacy at least equivalent to compounds already known.


We have now found a new family of compounds selected in a broad family of compounds which possess the above mentioned characteristics.


Accordingly, the present invention relates to N-[2-(2-pyridinyl)ethyl]carboxamide derivative of general formula (I):

The present invention also relates to a fungicidal composition comprising an effective amount of an active material of general formula (I). Thus, according to the present invention, there is provided a fungicidal composition comprising, as an active ingredient, an effective amount of a compound of general formula (I) as defined above and an agriculturally acceptable carrier or filler.


In the present specification, the term “support” denotes a natural or synthetic, organic or inorganic material with which the active material is combined to make it easier to apply, notably to the parts of the plant. This support is thus generally inert and should be agriculturally acceptable. The support may be a solid or a liquid. Examples of suitable supports include clays, natural or synthetic silicates, silica, resins, waxes, solid fertilisers, water, alcohols, in particular butanol, organic solvents, mineral and plant oils and derivatives thereof. Mixtures of such supports may also be used.


The composition may also comprise additional components. In particular, the composition may further comprise a surfactant. The surfactant can be an emulsifier, a dispersing agent or a wetting agent of ionic or non-ionic type or a mixture of such surfactants. Mention may be made, for example, of polyacrylic acid salts, lignosulphonic acid salts, phenolsulphonic or naphthalenesulphonic acid salts, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines, substituted phenols (in particular alkylphenols or arylphenols), salts of sulphosuccinic acid esters, taurine derivatives (in particular alkyl taurates), phosphoric esters of polyoxyethylated alcohols or phenols, fatty acid esters of polyols, and derivatives of the above compounds containing sulphate, sulphonate and phosphate functions. The presence of at least one surfactant is generally essential when the active material and/or the inert support are water-insoluble and when the vector agent for the application is water. Preferably, surfactant content may be between 5% and 40% by weight.


Optionally, additional components may also be included, e.g. protective colloids, adhesives, thickeners, thixotropic agents, penetration agents, stabilisers, sequestering agents. More generally, the active materials can be combined with any solid or liquid additive, which complies with the usual formulation techniques.


In general, the composition according to the invention may contain from 0.05 to 99% (by weight) of active material, preferably 10 to 70% by weight.


Compositions according to the present invention can be used in various forms such as aerosol dispenser, bait (ready for use), bait concentrate, block bait, capsule suspension, cold fogging concentrate, dustable powder, emulsifiable concentrate, emulsion oil in water, emulsion water in oil, encapsulated granule, fine granule, flowable concentrate for seed treatment, gas (under pressure), gas generating product, grain bait, granular bait, granule, hot fogging concentrate, macrogranule, microgranule, oil dispersible powder, oil miscible flowable concentrate, oil miscible liquid, paste, plant rodlet, plate bait, powder for dry seed treatment, scrap bait, seed coated with a pesticide, smoke candle, smoke cartridge, smoke generator, smoke pellet, smoke rodlet, smoke tablet, smoke tin, soluble concentrate, soluble powder, solution for seed treatment, suspension concentrate (flowable concentrate), tracking powder, ultra low volume (ulv) liquid, ultra low volume (ulv) suspension, vapour releasing product, water dispersible granules or tablets, water dispersible powder for slurry treatment, water soluble granules or tablets, water soluble powder for seed treatment and wettable powder.


These compositions include not only compositions which are ready to be applied to the plant or seed to be treated by means of a suitable device, such as a spraying or dusting device, but also concentrated commercial compositions which must be diluted before they are applied to the crop.


The compounds of the invention can also be mixed with one or more insecticides, fungicides, bactericides, attractant acaricides or pheromones or other compounds with biological activity. The mixtures thus obtained have a broadened spectrum of activity. The mixtures with other fungicides are particularly advantageous.


The fungicidal compositions of the present invention can be used to curatively or preventively control the phytopathogenic fungi of crops. Thus, according to a further aspect of the present invention, there is provided a method for curatively or preventively controlling the phytopathogenic fungi of crops characterised in that a fungicidal composition as hereinbefore defined is applied to the seed, the plant and/or to the fruit of the plant or to the soil in which the plant is growing or in which it is desired to grow.


The composition as used against phytopathogenic fungi of crops comprises an effective and non-phytotoxic amount of an active material of general formula (I).


The expression “effective and non-phytotoxic amount” means an amount of composition according to the invention which is sufficient to control or destroy the fungi present or liable to appear on the crops, and which does not entail any appreciable symptom of phytotoxicity for the said crops. Such an amount can vary within a wide range depending on the fungus to be combated, the type of crop, the climatic conditions and the compounds included in the fungicidal composition according to the invention.


This amount can be determined by systematic field trials, which are within the capabilities of a person skilled in the art.


The method of treatment according to the present invention is useful to treat propagation material such as tubers and rhizomes, but also seeds, seedlings or seedlings pricking out and plants or plants pricking out. This method of treatment can also be useful to treat roots. The method of treatment according to the present invention can also be useful to treat the overground parts of the plant such as trunks, stems or stalks, leaves, flowers and fruits of the concerned plant.

EXAMPLES OF PROCESS FOR PREPARATION OF THE COMPOUND OF GENERAL FORMULA (I)
Example A
Preparation of N-[2-(3-Chloro-5-trifluoromethyl-pyridin-2-yl) ethyl]-2-trifluoromethyl-nicotinamide



embedded image


A solution of 204 mg (1 mmol) of 2-trifluormethyl nicotinic acid, 200 mg (0.9 mmol) of 2-(3-chloro-5-trifluormethyl-pyridin-2-yl)-ethylamine and 620 mg (1.3 mmol) of bromotripyrrolidinophosphonium hexafluorophosphate and 230 mg (1.8 mmol) N,N-Diisopropylethylamine in 8 ml methylene chloride is stirred for 20 h at room temperature.


The mixture is diluted with 10 ml water, separated and the methylene chloride phase is washed with sat. NH4Cl solution and water. The organic phase is dried over sodium sulfate. After evaporation of the solvent the residue is purified by column chromatography over silica-gel (eluant:hexane/ethylacetate=10:1 to 1:1). Yield: 370 mg (98%).


Example B
Preparation of 2-Chloro-N-[2-(3-chloro-5-trifluoromethyl-pyrdin-2-yl)-ethyl]-6-methyl-nicotinamide



embedded image


A solution of 161 mg (0.7 mmol) 2-chloro-6-methylnictotinyl chloride, 160 mg (0.7 mmol) 2-(3-chloro-5-trifluormethyl-pyridin-2-yl)-ethylamine hydrochloride and 236 mg (1.7 mmol) sodium carbonate in 8 ml acetonitrile is stirred for 3 days at room temperature.


The mixture is diluted with 5 ml water and 5 ml ethylacetate, separated and the organic phase is washed with sat. NH4Cl solution and water. The organic phase is dried over sodium sulfate and evaporated. Yield: 200 mg (62%).


Example C
Preparation of 1-Methyl-3-trifluoromethyl-1H-pyrazole4-carboxylic acid [2-(3-chloro-5-trifluoromethyl-pyridin-2-yl)-ethyl]-amide



embedded image


132 mg (3.5 mmol) of sodium borohydrate is added in small portions to a solution of 370 mg (1.0 mmol) 1-methyl-3-trifluoromethyl-1H-pyrazole-4-carboxylic acid-anhydride, 110 mg (0.5 mmol) (3-chloro-5-trifluormethyl-pyridin-2-yl)-acetonitrile and 120 mg (0.5 mmol) Nickel(II) chloride hexahydrate in 5 ml of acetonitrile at 0° C. Stirring was continued at room temperature for 4 hours.


After evaporation of the solvent, the residue is purified by column chromatography over silica-gel (eluant:hexane/ethylacetate=10:1 to 1:1). Yield: 80 mg (40%).


Examples of Biological Activity of the Compound of General Formula (I)
Example 1
In Vivo Test on Alternaria brassicae (Leaf Spot of crucifers)

The active ingredient tested is prepared by potter homogenisation in a concentrated suspension type formulation at 100 g/l. This suspension is then diluted with water to obtain the desired active material concentration.


Radish plants (Pernot variety) in starter cups, sown on a 50/50 peat soil-pozzolana substrate and grown at 18-20° C., are treated at the cotyledon stage by spraying with the aqueous suspension described above.


Plants, used as controls, are treated with an aqueous solution not containing the active material.


After 24 hours, the plants are contaminated by spraying them with an aqueous suspension of Alternaria brassicae spores (40,000 spores per cm3). The spores are collected from a 12-13-day-old culture.
