Description

The invention relates to novel substituted pyridines and pyrimidines and condensed systems derived therefrom, processes for their preparation and their use as pesticides and fungicides.

It is already known that certain 4-amino- and 4-alkoxy-heterocycles have fungicidal, acaricidal and insecticidal activity (cf. for example EP-A-57 440, EP-A-196 524, EP-A-264 217, EP-A-326 329, EP-A-323 757, EP-A-432 894, DE-A-4 116 089, WO 93/04 580). However, the biological activity of these compounds, in particular at low application rates and concentrations, is not satisfactory in all use examples.

Novel, positively charged nitrogen heterocycles of the formula I have been found ##STR2## in which the radicals and groups are as defined below, which, while showing good tolerance by plants and favorable toxicity in respect of warm-blooded animals, are highly suitable for controlling animal pests, such as insects, arachnids, nematodes, helminths and molluscs, for controlling endoparasites and ectoparasites in the veterinary field, and for controlling harmful fungi.

The invention embraces both the pure isomers and mixtures thereof. The mixtures of diastereomers can be separated into the components by customary methods, for example by selective crystallization from appropriate solvents or by chromatography. Racemates can be resolved into the enantiomers by customary methods, for example by forming a salt with an optically active acid, separating the diastereomeric salts and liberating the pure enantiomers by means of a base.

The invention also relates to compositions, especially insecticidal and acaricidal compositions, which comprise the compounds of the formula I in addition to suitable formulation auxiliaries.

The compositions according to the invention comprise the active substances of the formula I in general in a proportion of from 1 to 95% by weight.

They can be formulated in various ways depending on the biological and/or chemicophysical parameters which prevail. Possible formulations which are suitable are therefore:

wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions, sprayable solutions, oil- or water-based dispersions (SC), suspoemulsions (SE), dusts (DP), seed-dressing products, granules in the form of microgranules, spray granules, coated granules and adsorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits.

These individual types of formulation are known in principle and are described, for example, in: Winnacker-Kuchler, "Chemische Technologie", Volume 7, C. Hauser Verlag Munich, 4th ed. 1986; van Falkenberg, "Pesticides Formulations", Marcel Dekker N.Y., 2nd ed. 1972-73; K. Martens, "Spray Drying Handbook", 3rd ed. 1979, G. Goodwin Ltd. London.

The formulation auxiliaries required, such as inert materials, surfactants, solvents and other additives, are likewise known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd ed., Darland Books, Caldwell N.J.; H. v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd ed., J. Wiley & Sons, N.Y.; Marsden, "Solvents Guide", 2nd ed., Interscience, N.Y. 1950; McCutcheon's, "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflafchenaktive Athylenoxidaddukte", Wiss.Verlagsgesell., Stuttgart 1967; Winnacker-Kuchler, "Chemische Technologie", Volume 7, C. Hauser Verlag Munich, 4th ed. 1986.

Based on these formulations, it is also possible to produce combinations with other pesticidally active substances, fertilizers and/or growth regulators, for example in the form of a readymix or a tank mix. Wettable powders are preparations, uniformly dispersible in water, which contain, beside the active substance and in addition to a diluent or inert material, wetting agents, for example polyoxethylated alkylphenols, polyoxethylated fatty alcohols, alkyl- or alkylphenolsulfonates, and dispersing agents, for example sodium ligninsulfonate or sodium 2,2'-dinaphthylmethane-6,6'-disulfonate.

Emulsifiable concentrates are prepared by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or higher-boiling aromatics or hydrocarbons, with addition of one or more emulsifiers. As emulsifiers, the following can be used, for example: calcium salts of alkylaryl-sulfonates, such as Ca dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or poly-oxethylene sorbitol esters.

Dusting agents are obtained by grinding the active substance with finely divided solid substances, for example talc, natural clays such as kaolin, bentonite, pyrophillite or diatomaceous earth. Granules can be prepared either by atomizing the active substance onto adsorptive, granulated inert material or by applying active substance concentrates onto the surface of carrier materials such as sand or kaolinites, or of granulated inert material, by means of adhesives, for example poly-vinyl alcohol or sodium polyacrylate, or alternatively mineral oils. Suitable active substances can also be granulated in the fashion conventional for the preparation of fertilizer granules, if desired as a mixture with fertilizers.

In wettable powders, the concentration of active substance is, for example, from approximately 10 to 90% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the concentration of active substance may be from approximately 5 to 80% by weight. Formulations in dust form comprise in most cases from 5 to 20% by weight of active substance, sprayable solutions from about 2 to 20% by weight. In the case of granules, the content of active substance depends partly on whether the active compound is in liquid or solid form and on which granulation auxiliaries, fillers, etc. are being used.

In addition, the abovementioned formulations of active substance comprise, if appropriate, the adhesives, wetting agents, dispersants, emulsifiers, penetrants, solvents, fillers or carriers which are customary in each case.

The concentrates, which are in the commercially customary form, are if appropriate diluted in the customary manner for their use, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and some microgranules. Dust and granule preparations, and also sprayable solutions, are normally not diluted any further with other inert substances before being used.

The application rate required varies with the external conditions, such as temperature and humidity among others. It can fluctuate within wide limits, for example between 0.0005 and 10.0 kg/ha or more of active substance, but is preferably between 0.001 and 5 kg/ha.

The active substances according to the invention may be present in their commercially customary formulations, and in the application forms prepared from these formulations, as mixtures with other active substances, such as insecticides, attractants, sterilants, acaricides, nematicides, fungicides, growth regulators or herbicides.

The pesticides include, for example, phosphates, carbamates, carboxylates, formamidines, tin compounds and substances produced by microorganisms, inter alia.

The active substance content of the use forms prepared from the commercially customary formulations can be from 0.00000001 to 95% by weight of active substance, preferably between 0.00001 and 1% by weight.

Application is effected in a conventional fashion, matched to the use forms.

The active substances according to the invention are also suitable for controlling ecto- and endoparasites in the veterinary sector or in the sector of animal husbandry.

The active substances according to the invention are in this case administered in a known fashion, such as by oral administration in the form of, for example, tablets, capsules, potions or granules, by dermal administration in the form of, for example, dipping, spraying, pouring-on and spotting-on and powdering, and also by parenteral administration in the form of, for example, injection.

The novel compounds, according to the invention, of the formula I can accordingly also be employed particularly advantageously in livestock husbandry (for example cattle, sheep, pigs and poultry such as chickens, geese etc.). In a preferred embodiment of the invention, the novel compounds, if appropriate in suitable formulations (cf. above) and if appropriate with the drinking water or feed, are administered orally to the animals. Since excretion in the droppings occurs in an effective fashion, the development of insects in the animal droppings can be prevented very simply in this fashion. The dosages and formulations suitable in each case are particularly dependent on the type and stage of development of the productive animals and also on the degree of infestation, and can easily be determined and fixed by conventional methods. In the case of cattle, the novel compounds can be employed, for example, in dosages of 0.01 to 1 mg/kg of body weight.

The compounds of the formula I according to the invention also have an outstanding fungicidal action. Fungal pathogens which have already penetrated the plant tissue can be successfully subjected to curative control. This is particularly important and advantageous in the case of those fungal diseases which can no longer be controlled effectively with the otherwise customary fungicides when infection has taken place already. The spectrum of action of the claimed compounds embraces various economically important phytopathogenic fungi, for example Plasmopara viticola, Phytophthora infestans, Erysiphe graminis, Pyricularia oryzae, Pyrenophora teres, Leptosphaeria nodorum, Pellicularia sasakii and Puccinia recondite.

In addition, the compounds according to the invention are also suitable for use in technical fields, for example as wood preservatives, as preservatives in paints, in cooling lubricants for metalworking, or as preservatives in drilling and cutting oils.

The active substances according to the invention in their commercially customary formulations can be employed either alone or in combination with other fungicides known from the literature.

Examples of fungicides which are known from the literature and which can be combined, in accordance with the invention, with the compounds of the formula I are the following products:

The abovementioned components for combinations are known active substances of which many are described in Ch. R. Worthing, S. B. Walker, The Pesticide Manual, 7th edition (1983), British Crop Protection Council. The active substance content of the use forms prepared from commercially customary formulations can vary within wide limits, and the concentration of active substance in the use forms can be from 0.0001 up to 95% by weight of active substance, preferably between 0.0001 and 1% by weight.

However, it can not be excluded with absolute certainty that the radical --CHR.sup.5 --E--R.sup.6 is linked to an N.sup.+ in position 3 of the pyrimidine system instead of an N.sup.+ in position 1 of this ring system.

C. BIOLOGICAL EXAMPLES

Use as Insecticide/acaracide/nematicide

Example 1

In each case 1 ml of the preparation to be examined, emulsified in acetone, is applied evenly to the inside of the lid and the bottom of a Petri dish. After the coating has dried, in each case 10 larvae of the German cockroach (Blattella germanica) are placed into the Petri dish. The dishes are sealed and kept at room temperature, and after 3 days, the mortality of the test animals is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 24 and 25 effect a mortality of 90-100% among the test animals used.

Example 2

1 ml of an aqueous solution of the formulated preparation to be examined is pipetted onto a filter disk. After the solution had dried, this filter is placed in a Petri dish and populated with 10 L2 larvae of the southern corn rootworm (Diabrotica undecimpunctata). After having been kept for 2 days in a climatized chamber at 26.degree. C., the mortality is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 25 effect a mortality of 90-100% among the test animals used.

Example 3

Cut stems of bean plants (Phaseolus vulgaris) carrying one leaf are transferred into brown glass bottles filled with tap water and subsequently populated with approximately 100 spider mites (Tetranychus urticae). The plant leaf and the spider mites are sprayed to run-off point with an aqueous solution of the formulated preparation to be examined. After the formulation has run off, plants and animals are stored in a climatized chamber (16 hours of light/day, 25.degree. C., 40-60% relative atmospheric humidity). After 6 days' storage, the effect of the preparation on all stages of the spider mite is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 24 and 25 cause a mortality of 90-100%.

Example 4

Culture medium (freeze-dried cube) is dipped into an aqueous solution of the formulated preparation to be examined and then placed in a Petri dish. 10 L2 larvae of the Egyptian cotton leaf worm (Spodoptera litoralis) are then placed in the Petri dish, which is subsequently sealed with a lid. After 4 days storage at about 23.degree. C., the effect of the preparation on the larvae is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 24 cause a 90-100% mortality or the larvae.

Example 5

(Contact activity): Approximately 5000 recently hatched, active (mobile) larvae (2nd development stage) of root gall nematodes (Meloidogyne incognita) are placed into a glass vessel containing an aqueous solution of the formulated preparation to be examined. After the nematode larvae have been continuously exposed for 2 days, the percentage of the specimens which have ceased to move (been immobilized) owing to the effect of the preparation is determined by comparison with the untreated controls (percent nematicidal contact activity).

At a concentration of 3 ppm (based in each case on the content of active compound), the preparations of Example No. 24 and 25 have a 90-100% activity against the root gall nematode Meloidogyne incognita.

Example 6

A Petri dish whose bottom is covered with filter paper and which contains about 5 ml of culture medium is prepared. 10 L2 larvae of the Egyptian cotton leaf worm (Spodoptera litoralis) are counted into a small beaker. 200 .mu.l of an aqueous solution of the formulated preparation to be examined are pipetted into the beaker. The treated larvae are then poured into the Petri dish and a further 200 .mu.l of the aqueous solution are spread over the culture medium. The Petri dish is sealed and then stored at about 25.degree. C. in a climatized chamber. After 6 days' storage, the effect of the preparation on the larvae is determined. At a concentration of 300 ppm (based on the content of active compound), the preparation of Example No. 526 effects a mortality of 90-100% among the larvae.

Example 7

A Petri dish whose bottom is covered with filter paper and which contains about 5 ml of culture medium is prepared. Pieces of filter paper with about 30, 24-hour-old eggs of the tobacco budworm (Heliothis virescens) are dipped into an aqueous solution of the formulated preparation to be examined for 5 seconds and subsequently placed in the Petri dish. A further 200 .mu.l of the aqueous solution are spread over the culture medium. The Petri dish is sealed and then kept at about 25.degree. C. in a climatized chamber. After 6 days' storage, the effect of the preparation on the eggs and the larvae which may have hatched from these is determined.

The leaves of 12 rice plants having a stem length of 8 cm are dipped for 5 seconds into an aqueous solution of the formulated preparation to be examined. After the solution has run off, the rice plants treated in this manner are placed in a Petri dish and populated with about 20 larvae (L3 stage) of the rice leafhopper species Nilaparvata lugens. The Petri dish is sealed and stored in a climatized chamber (16 hours of light/day, 25.degree. C., 40-60% relative atmospheric humidity). After 6 days' storage, the mortality among the leafhopper larvae is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 526, 528 and 780 effect a mortality of 90-100%.

Example 9

A Petri dish, half of whose bottom is covered with filter paper and which contains a germinated maize corn on a moist cotton pad, is prepared. About 50, 4-5-day-old eggs of the southern corn rootworm (Diabrotica undecimpunctata) are transferred onto the filter paper. Three drops of 200 .mu.l of an aqueous solution of the formulated preparation to be examined are pipetted onto the eggs, and the rest is pipetted onto the maize corn. The Petri dish is sealed and stored at about 25.degree. C. in a climatized chamber. After 6 days' storage, the effect of the preparation on the eggs and the larvae which may have hatched from these is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 179, 219 and 526 effect a mortality of 90-100%.

Example 10

Cut stems of bean plants (Phaseolus vulgaris) carrying one leaf are transferred into brown glass bottles filled with tap water and subsequently populated with approximately 100 spider mites (Tetranychus urticae). Plant leaf and spider mites are then dipped for 5 seconds into an aqueous solution of the formulated preparation to be examined. After the solution has run off, plants and animals are stored in a climatized chamber (16 hours of light/day, 25.degree. C., 40-60% relative atmospheric humidity). After 6 days' storage, the effect on the preparation on all stages of the spider mites is determined. At a concentration of 300 ppm (based on the content of active compound), the preparations of Example No. 179, 219, 486, 528 and 780 effect a mortality of 90-100%.

Example 11

(Contact activity): Approximately 5000 recently hatched, active (mobile) larvae (2nd development stage) of the root gall nematode (Meloidogyne incognita) are placed into a glass vessel containing an aqueous solution of the formulated preparation to be examined (final volume 20 ml). After the nematode larvae have been continuously exposed for 6 days, the percentage of the specimens which have ceased to move (been immobilized) owing to the effect of the preparation is determined by comparison with the untreated controls (percent nematicidal contact activity).

At a concentration of 3 ppm, the preparations of Example No. 219, 526, 528 and 780 have a 90-100% activity against the root gall nematode Meloidogyne incognita.
