1,3-oxazoline and 1,3-thiazoline derivatives, their preparation, and their use as pesticides

Abstract
1,3-Oxazoline and 1,3-thiazoline derivatives, their preparation, and their use as pesticides
Description


DESCRIPTION

[0001] The invention relates to diaryl-1,3-oxazolines and -1,3-thiazolines, to processes for their preparation, to compositions comprising them, and to their use for controlling animal pests, in particular insects, spider mites, ectoparasites and helminths.


[0002] Because of their biological activity, certain 1,3-oxazolines and 1,3-thiazolines are suitable for controlling animal pests (see, for example, EP-A-0 345 775 and EP-A-0 432 661; WO-A-97/06153; WO-A-93/24470 and WO-A-95/04726).


[0003] However, the level of action and/or duration of action of these prior-art compounds is not entirely satisfactory in all fields of application, in particular against certain organisms or when low concentrations are applied.


[0004] Since modern pesticides must meet a wide range of demands, for example regarding level, duration and spectrum of action, use spectrum, toxicity, combination with other active substances, combination with formulation auxiliaries or synthesis, and since the occurrence of resistances is possible, the development of such substances can never be regarded as concluded, and there is constantly a high demand for novel compounds which are advantageous over the known compounds, at least as far as some aspects are concerned.


[0005] It was an object of the present invention to provide compounds which widen the spectrum of the pesticides in various aspects.


[0006] This object, and other objects which are not mentioned explicitly and which can be deduced or concluded from the ideas discussed herein, is solved by 1,3-oxazoline and 1,3-thiazoline derivatives of the formula (I)

[0104] The present invention relates to the compounds of the formula (I) in the form of the free base or of an acid addition salt. Acids which can be used for salt formation are inorganic acids such as hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid, phosphoric acid or organic acids such as formic acid, acetic acid, propionic acid, malonic acid, oxalic acid, fumaric acid, adipic acid, stearic acid, oleic acid, methane sulfonic acid, benzene sulfonic acid or toluene sulfonic acid.


[0105] Some of the compounds of the formula (I) have one or more asymmetric carbon atoms or stereoisomers on double bonds. Enantiomers or diastereomers may therefore occur. The invention encompasses not only the pure isomers, but also their mixtures. The diastereomer mixtures can be resolved into the components by customary methods, for example by selective crystallization from suitable solvents or by chromatography. Racemates can be resolved into the enantiomers by customary methods, for example by salt formation with a chiral, enantiomerically pure acid, separation of the diastereomeric salts and liberation of the pure enantiomers by means of a base.


[0106] Very especially preferred are the following groups of compounds of the formula (Ia) to (Ie):
6


[0107] In these formulae X1, X2, Z, R4, R5 and R6 each have the meanings given in the formula (I) (X1, X2{circumflex over (=)}X).


[0108] Particularly preferred are compounds of the formula (Ia1) to (Ia4):
7


[0109] Z, R5 and R6 each have in this case the meanings given in the formula (I).


[0110] The compounds according to the invention are prepared by methods which are known per se from the literature as they are described in standard works on organic synthesis, for example Houben-Weyl, Methoden der Organischen Chemie [Methods in Organic Chemistry], Georg-Thieme-Verlag, Stuttgart.


[0111] The preparation is carried out under reaction conditions which are known and suitable for the abovementioned reactions. Other variants which are known per se, but not illustrated here in greater detail, may also be made use of.


[0112] If desired, the starting materials may also be formed in situ, in such a way that they are not isolated from the reaction mixture but immediately reacted further to give the compounds of the formula (I).


[0113] The general chemistry of the 1,3-oxazolines is described, for example, in Tetrahedron, 1994, 50, 2297-2360 and in Nachr. Chem. Tech. Lab. 1996, 44, 744-750.


[0114] The invention also relates to a process for the preparation of compounds of the formula (I) by reacting known 1,3-oxazolines and 1,3-thiazolines of the formula (II) (see, for example, EP-A-0 345 775) (suitably substituted by R1, R2, R3) with metalloid-pyridine compounds of the formula (III) (suitably substituted by R4, R5, R6), which comprises reacting a halogen and perfluoroalkylsulfonate compound of the formula (II)
8


[0115] in which


[0116] Y is Cl, Br, I or perfluoroalkylsulfonate and


[0117] A, Z and E have the meanings given in formula (I)


[0118] with an organometallic compound of the formula (III)


G—M  (III)


[0119] in which


[0120] M is a B-, Sn- or Zn-containing leaving group and


[0121] G has the meaning given in formula (I),


[0122] with palladium catalysis.


[0123] The methods of A to H for the synthesis of a variety of subgroups of compounds of the formula (I) may be mentioned by way of example:
9


[0124] Linkage of the phenyl ring with a pyridine ring is effected, for example, by palladium catalysis using Suzuki coupling, Stille coupling or Negishi coupling (see, for example, P. Knochel, Chem. Review 1993, 93, 2117-2188 or Jiro Tsuji, Palladium Reagents and Catalysts, John Wiley & Sons, 1996).


[0125] It is also possible for the functions required for the linkage to be swapped between (II) and (III):
10


[0126] It is also possible first to construct a pyridyl-phenyl structural unit and to convert these precursors into 1,3-oxazolines and 1,3-thiazolines of the formula (I).

[0127] The oxazoline precursors of the formula (II) are prepared, for example, by the following routes, some of which are known (EP-A-0 432 661; G. Helmchen, Tetrahedron 1996, 52, 7547-7583)):


[0128] Activated carboxylic acid derivatives are reacted with aminoalcohols (VI) (suitably substituted by R1, R2, R3) (Synthesis K. Drauz, J. Org. Chem. 1993, 58, 3568-3571) to give the amidoalcohols (VII):
12


[0129] The chlorides (VIII) (Y═Cl) are obtained from the amidoalcohols (VII) for example using thionyl chloride; when sulfone halides are used, the sulfonates (VII) (Y=for example mesylate, tosylate) are formed.


[0130] The oxazolines (II) are formed from (VIII) by the action of bases.
13


[0131] Bases which are suitable are, for example, basic salts such as alkali metal hydroxides, alkali metal carbonates, hydrides, alkoxides and amines. Starting from the 4-hydroxyphenyl derivatives of (II), the triflates may be obtained by sulfonation with, for example, trifluoromethanesulfonyl chloride.


[0132] The oxazoline precursors of the formula (IV) which contain a tin group are accessible by Stille coupling with distannane:
14


[0133] The pyridine precursors of the formula (III) are formed, for example, by generating metalated pyridine derivatives with the suitable substituents R4, R5, R6 as per formula (I) and their reaction with, for example, boric esters, tin halides or zinc halides.
15


[0134] The aminoalcohol precursors (VI) can be prepared by reducing known 2-hydroxyacetophenone oximes by means of hydride.
16


[0135] Collections of compounds of the formula (I) which can be synthesized by the abovementioned scheme may also be prepared in a parallel manner, and this may be effected manually or in a semiautomated or fully automated manner. In this case, it is possible, for example, to automate the procedure of the reaction, work-up or purification of the products or of the intermediates. In total, this is to be understood as meaning a procedure as it is described, for example, by S. H. DeWitt in “Annual Reports in Combinatorial Chemistry and Molecular Diversity: Automated synthesis”, Volume 1, Verlag Escom 1997, pages 69 to 77.


[0136] A series of commercially available apparatuses as they are offered by, for example, Stem Corporation, Woodrolfe Road, Tollesbury, Essex, CM9 8SE, England or H+P Labortechnik GmbH, Bruckmannring 28, 85764 Oberschleiβheim, Germany, may be used for the parallel procedure of the reaction and work-up. For the parallel purification of compounds of the formula (I), or of intermediates obtained during the preparation, use may be made, inter alia, of chromatography apparatuses, for example those by ISCO, Inc., 4700 Superior Street, Lincoln, Nebr. 68504, USA.


[0137] The apparatuses mentioned lead to a modular procedure in which the individual process steps are automated, but manual operations must be performed between the process steps. This can be prevented by employing semi-integrated or fully integrated automation systems where the automation modules in question are operated by, for example, robots. Such automation systems can be obtained, for example, from Zymark Corporation, Zymark Center, Hopkinton, Mass. 01748, USA.


[0138] In addition to what has been described here, compounds of the formula (I) may be prepared in part or fully by solid-phase-supported methods. For this purpose, individual intermediate steps or all intermediate steps of the synthesis or of a synthesis adapted to suit the procedure in question are bound to a synthetic resin.


[0139] Solid-phase-supported synthesis methods are described extensively in the specialist literature, for example Barry A. Bunin in “The Combinatorial Index”, Academic Press, 1998.


[0140] The use of solid-phase-supported synthesis methods permits a series of protocols which are known from the literature and which, in turn, can be performed manually or in an automated manner. For example, the “tea-bag method” (Houghten, U.S. Pat. No. 4,631,211; Houghten et al., Proc. Natl. Acad. Sci, 1985, 82, 5131-5135), in which products by IRORI, 11149 North Torrey Pines Road, La Jolla, Calif. 92037, USA, are employed, may be semiautomated. The automation of solid-phase-supported parallel syntheses is performed successfully, for example, by apparatuses by Argonaut Technologies, Inc., 887 Industrial Road, San Carlos, Calif. 94070, USA or MultiSynTech GmbH, Wullener Feld 4, 58454 Witten, Germany.


[0141] The preparation of the processes described herein yields compounds of the formula (I) in the form of substance collections which are termed libraries. The present invention also relates to libraries which comprise at least two compounds of the formula (I).

[0166] The plant-parasitic nematodes which can be controlled in accordance with the invention include, for example, the root-parasitic soil-dwelling nematodes such as, for example, those of the genera Meloidogyne (root knot nematodes, such as Meloidogyne incognita, Meloidogyne hapla and Meloidogyne javanica), Heterodera and Globodera (cyst-forming nematodes, such as Globodera rostochiensis, Globodera pallida, Heterodera trifolii) and of the genera Radopholus, such as Radopholus similis, Pratylenchus such as Pratylenchus neglectus, Pratylenchus penetrans and Pratylenchus curvitatus; Tylenchulus such as Tylenchulus semipenetrans, Tylenchorhynchus, such as Tylenchorhynchus dubius and Tylenchorhynchus daytoni, Rotylenchus such as Rotylenchus robustus, Heliocotylenchus such as Haliocotylenchus multicinctus, Belonoaimus such as Belonoaimus longicaudatus, Longidorus such as Longidorus elongatus, Trichodorus such Trichodorus primitivus and Xiphinema such as Xiphinema index.


[0167] Other nematode genera which can be controlled using the compounds according to the invention are Ditylenchus (stem parasites, such as Ditylenchus dipsaci and Ditylenchus destructor), Aphelenchoides (foliar nematodes, such as Aphelenchoides ritzemabosi) and Anguina (seed nematodes, such as Anguina tritici).


[0168] The invention also relates to compositions, for example crop protection compositions, preferably insecticidal, acaricidal, ixodicidal, nematicidal, molluskicidal or fungicidal, especially preferably insecticidal and acaricidal, compositions which comprise one or more compounds of the formula (I) in addition to suitable formulation auxiliaries.


[0169] In general, the compositions according to the invention comprise 1 to 95% by weight of the active substances of the formula (I).


[0170] To prepare the compositions according to the invention, the active substance and the other additives are combined and brought into suitable use form.


[0171] They can be formulated in various ways, depending on the biological and/or chemical-physical parameters which prevail. The following are examples of possible formulations:


[0172] 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 absorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits.


[0173] These individual types of formulations are known in principle and are described, for example, in:


[0174] Winnacker-Küchler, “Chemical Technology”, Volume 7, C. Hauser Veriag Munich, 4th Edition 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.


[0175] The necessary formulation auxilairies such as inert materials, surfactants, solvents and other additives, are also known and described, for example, in Watkins, “Handbook of Insecticide Dust Diluents and Garriers”, 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; Schönfeldt, “Grenzflächenaktive Äthylenoxidaddukte”, [Surface-active ethylene oxide adducts] Wiss. Verlagsgesell., Stuttgart 1967; Winnacker-Küchler, “Chemische Technologie”, Volume 7, C. Hauser Verlag Munich, 4th Edition 1986.


[0176] Based on these formulations, it is also possible to prepare combinations with other pesticidally active materials, fertilizers and/or growth regulators, for example in the form of a ready-mix formulation or a tank mix. Wettable powders are preparations which are uniformly dispersible in water which, besides the active substance, also comprise wetters, for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, alkylsulfonates or alkylphenolsulfonates and dispersants, for example sodium lignosulfonate or sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, in addition to a diluent or inert material.


[0177] Emulsifiable concentrates are prepared by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or else higher-boiling aromatics or hydrocarbons, with addition of one or more emulsifiers. As emulsifiers, the following can be used, for example: calcium alkylarylsulfonates such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters.


[0178] Dusts are obtained, for example, by grinding the active substance with finely divided solid materials, for example talc or natural clays, such as kaolin, bentonite, pyrophyllite 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 polyvinyl alcohol or sodium polyacrylate, or else mineral oils. Suitable active substances can also be granulated in the manner which is customary for the preparation of fertilizer granules, if desired as a mixture with fertilizers.


[0179] The active substance concentration in wettable powders is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight is composed of customary formulation auxiliaries. In the case of emulsifiable concentrates, the active substance concentration may be approximately 5 to 80% by weight. Formulations in the form of dusts usually comprise 5 to 20% by weight of active substance, sprayable solutions approximately 2 to 20% by weight. In the case of granules, the active substance content depends partly on whether the active compound is in liquid or solid form and on which granulation auxiliaries, fillers and the like are being used.


[0180] Besides, the abovementioned active substance formulations comprise, if appropriate, the tackifiers, wetters, dispersants, emulsifiers, penetrants, solvents, fillers or carriers which are conventional in each case.


[0181] For use, the concentrates, which are present in commercially available form, are, if desired, diluted in the customary manner, for example in the case of wettable powders, emulsifiable concentrates, dispersions and in some cases also microgranules using water. Preparations in the form of dusts and granules and sprayable solutions are usually not diluted any further with other inert substances prior to use.


[0182] The application rate required varies with the external conditions such as, inter alia, temperature and humidity. It may vary within wide limits, for example between 0.0005 and 10.0 kg/ha or more of active substance, but it is preferably between 0.001 and 5 kg/ha.


[0183] The active substances according to the invention, in their commercially available formulations and in the use forms prepared from these formulations (see the abovementioned compositions) may be present in mixtures with other active substances such as insecticides, attractants, sterilants, acaricides, nematicides, fungicides, molluskicides, growth regulatory substances or herbicides.


[0184] The pesticides include, for example, phosphoric esters, carbamates, carboxylic esters, formamidines, tin compounds and materials produced by microorganisms.

[0198] The active substance content of the use forms prepared from the commercially available formulations may range from 0.00000001 up to 95% by weight of active substance, preferably between 0.00001 and 1% by weight. Application is effected in a customary manner adapted to suit the use forms.


[0199] The invention also relates to a method of controlling harmful insects, Acarina, mollusks and/or nematodes in which an effective amount of a compound according to the invention or of a composition according to the invention is applied to these or to the plants, areas or substrates infested with them.


[0200] The use of a compound according to the invention or of a composition according to the invention for controlling harmful insects, Acarina, mollusks and/or nematodes is also the subject of the invention.


[0201] The active substances according to the invention are also suitable for use in the veterinary medicine sector, preferably for controlling endoparasites and ectoparasites, and in the field of animal keeping.


[0202] The active substances according to the invention may be applied in the known manner, such as by oral administration in the form of, for example, tablets, capsules, drinks or granules, by dermal application in the form of, for example, dipping, spraying, pouring on and spotting on, and dusting, and by parenteral administration in the form of, for example, an injection.


[0203] In addition, the compounds according to the invention are also suitable for use in technology, for example as wood preservative, as preservative in paints, in cooling lubricants for metalworking, or as preservative in drilling and cutting oils.


[0204] Accordingly, the compounds of the formula (I) according to the invention can also be employed particularly advantageously in livestock keeping (for example cattle, sheep, pigs and poultry such as chickens, geese and the like). In a preferred embodiment of the invention, the novel compounds, if appropriate in suitable formulations (cf. above), are administered orally to the animals, if appropriate together with the drinking water or feed. Since excretion in the feces is highly efficient, the development of insects in the animals' feces can be prevented very easily in this manner. The dosages and formulations which are suitable in each case depend, in particular, on the species and the developmental stage of the productive livestock and also on the risk of infestation and can be determined readily and established by customary methods. For example, the compounds can be employed in cattle at dosages of 0.01 to 1 mg/kg bodyweight.


[0205] The compounds of the formula (I) according to the invention are also distinguished by an outstanding fungicidal action. Fungal pathogens which have already penetrated the plant tissue can be controlled successfully in a curative manner. This is especially important and advantageous in the case of those fungal diseases which can no longer be controlled effectively by the fungicides which are otherwise customary once infection has taken place. The spectrum of action of the claimed compounds encompasses a variety of economically important phytopathogenic fungi such as, for example, Plasmopara viticola, Phytophthora infestans, Erysiphe graminis, Pyricularia oryzae, Pyrenophora teres, Leptosphaerea nodorum and Pellicularia sasakii and Puccinia recondite.


[0206] These, but also predominantly insecticidally, acaricidally, molluskicidally or nematocidally active compounds of the formula (I), can be applied, in their commercially available formulations, either alone or in combination with other fungicides known from the literature.

[0209] The abovementioned components for combinations are known active substances, many of which are described in C. D. S. Tomlin, S. B. Walker, The Pesticide Manual, 11th Edition, British Crop Protection Council, Farnham 1997.


[0210] The active substance content of the use forms prepared from the commercially available formulations can be varied within wide ranges, the active substance concentration of the use forms may range from 0.0001 up to 95% by weight of active substance, preferably from 0.0001 to 1% by weight. They are applied in a customary manner adapted to suit the use forms.


[0211] They are used in a customary manner adapted to suit the use forms, for example by applying, in order to control pathogenic fungi, a fungicidally effective amount of a compound according to the invention or of a composition according to the invention to these fungi or to the plants, areas of substrates infested with them, or to seed.


[0212] The invention also relates to seed, treated or coated with an effective amount of a compound according to the invention or of a composition according to the invention.


[0213] The compounds of the formula (I) can also be employed for controlling harmful organisms in crops of known genetically engineered plants or genetically engineered plants yet to be developed. As a rule, the transgenic plants are distinguished by especially advantageous properties, for example by resistances to particular crop protection agents, resistances to plant diseases or pathogens of plant diseases, such as particular insects or microorganisms such as fungi, bacteria or viruses. Other particular properties concern, for example, the harvested material with regard to quantity, quality, storage properties, composition and specific constituents. Thus, transgenic plants are known where the starch content is increased, or the starch quality is altered, or where the harvested material has a different fatty acid composition.


[0214] The use in economically important transgenic crops of useful plants and ornamentals is preferred, for example of cereals such as wheat, barley, rye, oats, millet, rice, cassava and maize or else crops of sugar beet, cotton, soya, oilseed rape, potatoes, tomatoes, peas and other types of vegetables.


[0215] When used in transgenic crops, in particular those which have resistances to insects, effects are frequently observed, in addition to the effects against harmful organisms to be observed in other crops, which are specific for application in the transgenic crop in question, for example an altered or specifically widened spectrum of pests which can be controlled, or altered application rates which may be employed for application.


[0216] The invention therefore also relates to the use of compounds of the formula (I) for controlling harmful organisms in transgenic crop plants.


[0217] The use according to the invention of compounds of the formula (I) or of compositions comprising them, for example as insecticide, acaricide, molluskicide, nematicide or fungicide, also includes the case where the compound of the formula (I) or its salt is formed from a precursor only after application, for example in the insect, in a plant or in the soil.


[0218] The contents of the German Patent Application 198 15 026.1, whose priority is claimed by the present application, and the contents of the appended summary are therefore expressly incorporated by reference; they are part of the present description by way of quotation.







[0219] The examples which follow are intended to illustrate the invention without restricting it thereto.


A. PREPARATION EXAMPLES


Precursor VP 1: 4′-bromo-2-hydroxyacetophenone O-methyloxime

B. FORMULATION EXAMPLES

[0279] a) A dust is obtained by mixing 10 parts by weight of active substance and 90 parts by weight of talc as inert material and comminuting the mixture in a hammer mill.


[0280] b) A wettable powder which is readily dispersible in water is obtained by mixing 25 parts by weight of active substance, 65 parts by weight of kaolin-containing quartz as inert material, 10 parts by weight of potassium lignosulfonate and 1 part by weight of sodium oleoylmethyltaurinate as wetter and dispersant and grinding the mixture in a pinned-disk mill.


[0281] c) A dispersion concentrate which is readily dispersible in water is prepared by mixing 40 parts by weight of active substance with 7 parts by weight of a sulfosuccinic monoester, 2 parts by weight of a sodium lignosulfonate and 51 parts by weight of water and grinding the mixture in a ball mill to a fineness of below 5 microns.


[0282] d) An emulsifiable concentrate can be prepared from 15 parts by weight of active substance, 75 parts by weight of cyclohexanone as solvent and 10 parts by weight of oxyethylated nonylphenol (10 EO) as emulsifier.


[0283] e) Granules can be prepared from 2 to 15 parts by weight of active substance and an inert granule carrier material such as attapulgite, pumice granules and/or quartz sand. It is expedient to use a suspension of the wettable powder of Example b) with a solids content of 30%, which is sprayed onto the surface of attapulgite granules, and these are dried and mixed intimately. The wettable powder amounts to approx. 5% by weight and the inert carrier material to approx. 95% by weight of the finished granules.



C. BIOLOGICAL EXAMPLES


Example 1


Effect on the Spider Mites Tetranychus urticae

[0284] Bean plants (Phaseolus vulgaris) which were severely infested with a complete population of spider mites (Tetranychus urticae) were sprayed to runoff point with an aqueous solution of the formulated preparation to be tested. The mortality of all mite stages was determined after 7 days. At a concentration of 300 ppm (based on active substance content), a 90-100% mortality was shown by the preparations of Examples 1, 2, 3, 4, 7, 8, 9, 14, 18, 21, 31, 40, 41, 43, 44, 47, 51, 106, 152 and 153.



Example 2


Effect on the Aphid Aphis fabae

[0285] Field beans (Vicia faba) which were densly populated with the black bean aphid (Aphis fabae) were sprayed to runoff point with an aqueous solution of the formulated preparation to be tested. The mortality of the aphids was determined after 3 days. At a concentration of 300 ppm (based on the active substance content), a 90-100% mortality was shown by the preparations of Examples 1, 2, 3, 4, 7, 8, 152.



Example 3


Effect on the Butterfly Larva Spodoptera litoralis

[0286] Ten L4 larvae of the Egyptian cotton leafworm (Spodoptera litoralis) were introduced into a Petri dish whose bottom was covered with filter paper and contained approx. 5 ml of nutrient medium. Filter paper, nutrient paper and the larvae which had been introduced were then sprayed with an aqueous solution of the formulated preparation to be tested. The Petri dish was subsequently sealed with a lid. After 4 days' storage at approx. 23° C., the effect of the preparation on the larvae was determined. At a concentration of 300 ppm (based on the active substance content), a 90-100% larval mortality was caused by the preparations of Examples 3, 4, 22, 105, 106.



Example 4


Effect on the Egg-Larval Stage of Heliothis virescens

[0287] A Petri dish whose bottom was covered with filter paper and which contained approx. 5 ml of nutrient medium was prepared. Filter paper sections containing approx. 30 24-hour-old eggs of the tobacco budworm (Heliothis virescens) were immersed for 5 seconds into an aqueous solution of the formulated preparation to be tested and subsequently placed in the Petri dish. A further 200 μl of the aqueous solution were distributed over the nutrient medium. After the Petri dish had been sealed, it was stored in a controlled-environment cabinet at approx. 25° C. After 6 days' storage, the mortality of the preparation on the eggs and any larvae hatched from them was determined. At a concentration of 300 ppm (based on the active substance content), a 90-100% mortality was caused by the preparations of Examples 1, 2, 3, 4, 5, 6, 7, 8, 14, 17, 21, 22, 23, 34, 35, 39, 40, 43, 44, 106.



Example 5


Effect on the Corn Budworm Diabrotica undecimpunctata

[0288] Maize seed was pregerminated for 6 hours while submerged in water, then placed into 10-ml glass tubes and covered with 2 ml of soil in each case. After 1 ml of water had been added, the plants remained in the glass tubes at 21° C. until plant length was approx. 3 cm. 10 L2 larvae of the corn budworm (Diabrotica undecimpunctata) were then introduced into each tube on the soil. Two hours later, 1 ml of an aqueous solution of the formulated preparation to be tested were pipetted onto the soil surface in the tubes. After storage for 5 days under laboratory conditions at 21° C., the soil and root sections were examined for live Diabrotica larvae and the mortality was determined. At a concentration of 300 ppm (based on the active substance content), a 100% mortality of the test animals employed was shown by the preparations of Example 2, 3, 5, 9, 19, 39.



Example 6


Effect on the Larvae of the Copperbottle Lucilia cuprina

[0289] In a sample container, 20 recently hatched larvae of the copperbottle Lucilia cuprina were placed on a larval nutrient medium of ground mutton which contained the test substance in a concentration of 100 ppm. Larval growth on the nutrient medium is monitored over 72 hours up to larva 3. At a concentration of 100 ppm (based on the active substance content), a 100% mortality in the fly larvae employed was shown by the preparations of Examples 2, 3, 4, 5, 105, 106.



Example 7


Effect on Developmental Stages of the Cat Flea Ctenocephalides felis

[0290] The larval nutrient medium of the cat flea, composed of equal parts of blood meal and quartz sand, was admixed with the test substance at a concentration of 1000 ppm. Approx. 30 flea eggs freshly obtained from a breeding colony were transferred onto the medium. To assess the affect of the preparation, hatching of the flea larvae and their development into pupae and adult fleas was observed. A mortality of 100% was caused by the test substances of Examples 2, 3 and 4.
