Description

NEW INSECTICIDES AND SYNERGISTIC RISKS Frequently, the potency of biological pesticides is insufficient to protect the c of useful plants, prly, against pests. For this reason, until now, preference has been given to chemical insecticides. It is intended an integrated cprotection to minimize the use of chemical substances, without having to accept simultaneously reduced yields. The publication of Soper and co-authors (1974, Enviromental Entomology, 3, 560-562) describes that the development of entomopathogenic fungi is inhibited by the simultaneous use of insecticides. When this depends on the type and amount of the agent used, it can be seen from the data that there is a powerful adverse effect on the development of the fungi. Filho and coauthors (1987, Biological, 53, 7-12, 69-70) also report that the development of Beauveria bassiana is inhibited by a variety of insecticides. EP 0 668 722 only describes that the fungus Beauveria bassiana can be used in combination with endosulfan. EP 0 627 165 describes environmental pathogenic fungi in combination with insecticides to control cockroaches.

Cft 2 086 351 further describes the use of entomopathogenic fungi together with insecticides to control termites. Surprisingly, biological experiments have now identified insecticides with a completely different structure that when used in conjunction with spores or particles of an entomopathogenic fungus show an excessively good activity against a broad spectrum of a variety of insects and mites. The present invention relates to insecticidal and acaricidal compositions comprising an effective amount of at least one insecticidal composition, selected from the group of parapyrethroids, the group of nitromethylenes, the group of carbamates and the group of phenylpyrazoles, in combination with at least one pathogenic fungus (component B). The invention particularly relates to compositions having the following insecticides, as components, in mixtures: (1) Parapyrethroids (pyrethroids other than ester) such as, for example, eilafluofen (4-ethoxyphenyl-C3- (4-fluoro- 3-phenoxyphenyl) pl] dimethylsilane, fil component of the formula I): and etofenpróx ((2- (4-ethoxyphenyl) -2-methylpl 3-phenoxybenzyl ether, component R2 of formula II): (2) Nitromethylenes, such as, for example, Imidacloprid (1- (6-chloro-3) -pyridylmet l) -N-nitroimidazolidin-2-ylidenearnine, component R3 of formula III): NI25 ((E) -NiC (6-chloro-3-pyridyl) methyl] -N2-cyano-Ni-methyl-acetamidine, component R4 of formula IV): Nitenpyram ((E) -N- (6-chloro-3-pyridylmethyl) -N-ethyl-N '-methyl-2-nitrovinylidene ina, component R5 of the formula (V)): (3) Carbamates, such as, for example: Phenoxycarb (ethyl 2- (4-phenoxyphenoxy) ethylcarbamate, component R6 of formula VI) (4) Phenylpyrazoles, such as, for example: Fipronil ((+) - 5-amino-1- (2,6-dichloro-a,, α-trifluoro-p-tolyl) -4-trifluoromethylsulfinyl-irazol-3- carbonitrile, component R7 of formula VII) The compounds mentioned above are all known in the literature ("Pesticide Nanual", 10th edition, Br.it. C Prot. Council, 1994) and are commercially available. A particularly interesting action against insects is shown by a mixture of silafluofen and fungi of the g + eneros Rcrernonioum, Rcanthomycee, Rschersonia, flspergillus, Beauveria, Culicinomyces, Engyodontium, Funicularis, F? Sarium, Gebellula, Hirsutella, Hymenstilbe, ri? Ta hiziurn, No uraea, Paecilo yces, Paraisaria, Pleurodesmopora, Polycephalo yces, Pseudogibellula,? orosporella, Sporothrix, "Stilbella", Tetracrium, Tetranacriurn, Tilachlidiurn, Tolypocladiu and Verticilliurn. All these genera are assigned to the section of Deuterornycota (Sarnson and coauthors, "Atlas of Entomopathogenic Fungi, 1988, Springer Verlag) .The fungi of the genera Hirsutella, Verticilliurn, fletarhiziuro, Beauveria, Paecilornyces and Nornuraea are of particular interest. The mycoinsecticide constituent may be present in a variety of forms: as conidiospores, as blastospores, as or sets of hy eae, as hyphal fragments or as a mixture of two or more of the forms mentioned above. In particular, the invention relates to insecticidal and acaricidal compositions comprising the fungus Beauveria bassiana or Metarhizium anisoplii. The fungus Beauveria bassiana has been described by Bassi, fl. (1836, C.R.Rcad, Sci. Paris 2, 434 to 436), Domsch, V.H. and co-authors (190, Compendium of Soil Fungi 1, 136-139) and Samson, R.R. and co-authors (1988, Atlas of Entomopathogenic Fungi, Springer-Verlag, Berlin) and obtainable from Mycotech (Butte, Montana, EUR), Hoechst Schering AgrEvo GmbH and Troy Sciences (formerly Fermone Corp.) (Phoenix, Rrizona, EUR ). In the text that follows, the term active substance is also used for each of the two components A or B. The mixing ratios of the two components can vary within wide limits. They depend in particular on the component used in the mixture, the stage of development of the pests and the climatic conditions. The invention also relates to compositions comprising the two components A and B in addition to the suitable formulation aids. The combinations of active substance according to the invention can exist not only as mixed formulations of the two components which are then diluted with water in the usual manner or applied as granules, but also in the form of so-called tank mixtures, by diluting together the components, which are formulated separately, with water. Based on these formulations, it is also possible to prepare combinations with other pesticidally active substances, such as selective herbicides and fungicides or specific insecticides, and also fertilizers and / or growth regulators, for example, in the form of a ready-to-use mixture. or of a tank mix. The components can be formulated in a variety of ways, depending on the biological and / or chemophysical parameters that prevail. The appropriate formulation options are, for example; yeast formulations, starch formulations, wettable powders (PH), emuleifi cable concentrates (CE), aqueous solutions (SL), emulsions (EU), such as oil-in-water and water-in-oil emulsions, spray solutions or emulsions, water-based or oil-based dispersions, it assumes ions, powders (DP), seed treatment products, granules for application or spreading in the soil, or water-dispersible granules (UG), ULV formulations, microcapsules or baits (substrates) . Particularly interesting are oil-in-water and water-in-oil emulsions, wettable powders or granules. These individual types of formulation are known in principle and are described, for example, in: Uinnacker-Küchler, "Chemische Technologie" ["Chemical Technology3, volume 7, C. Hauser Verlag Munich, 4th edition, 1986; van Valkenburg," Pesticide Formulations ", Marcel Dekker, NY, 2nd edition, 1972-73, K. Martens," Spray Drying Handbook ", 3rd edition, G. Goodwin Ltd. London, The required formulation aids, such as inert materials , surfactants, solvents and other additives are also known and described, for example, in: Uatkins "Handbook of Insecticide Dust Diluents and Carriers," 2nd edition, Darland Books, Caldwell, NJ; H. v. Olphen, " Introduction to Clay Colloid Chernistry, 2nd edition, 3.

Verlagsgesell, Stuttgart 1976; Uinnacker-Küchler, "Chemische Technologie" [Chemical Technology} , volume 7, C. Hauser Verlag Munich, 4th. Edition, 1986. Wettable powders are preparations which are uniformly dispersed in water and which, in addition to the active substance, also comprise wetting agents, for example, polyoxyethylated alkyl phenols, polyoxyethylated fatty alcohols or fatty amines, alkanesulfonates or alkylbenzenesulfonates and dispersants. , for example, sodium lignosulfonate, Sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, sodium dibutylnaphthalene sulfonate or even sodium oleoylmethyltaurinate, in addition to the diluent or the inert substance. The emulsifiable concentrates are prepared by dissolving the active substance in an organic solvento, for example, butane, cyclohexanone, dirnethylformamide, xylene or high-boiling compounds or aromatic hydrocarbons, with the addition of one or more emulsifiers. Examples of the emulsifiers that may be used are: calcium alkylarylsulfonate, such as calcium dodecylbenzenesulfonate or nonionic emulsifiers, such as polyglycol fatty acid esters, polyglycolyl alkylaryl ethers, fatty alcohol polyglycol ethers, oxide condensates of propylene / ethylene oxide, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters. Powders can be obtained by grinding the active substance with finely divided solid substances, for example, talc, natural clays, such as kaolin, bentonite and pyrophyllite and diatomaceous earth. Granules can be produced either by spreading the active substance on an inert adsorbent, granulated material, or by applying concentrates of active substance on the surface of carriers, such as sand, kaolinites or granulated inert material, by means of binders, for example, alcohol. polyvinyl, sodium polyacrylate or, alternatively, mineral oils. It is also possible to granulate suitable active substances in the manner that is conventional for the production of fertilizer granules, if desired, in a mixture with fertilizers. As a general rule, the agrochemical preparations comprise from 0.0001 to 99 weight percent, in particular-between 0.0005 and 95%, preferably between 2 and 90% of the two components A and B. The low concentrations, that is, 0.0001 at 2%, they are advantageously used to control undesirable social insects, as has been suggested in P 44 03 062.2. The concentrations of active substances A and B may differ in the formulations. The concentration of active substance in wettable powders, for example, is about 10 to 90 weight percent; the remainder up to 100 weight percent is composed of conventional formulation components. In the case of concentrates and ulsifiable, the concentration of active substance can be from 1 to 90 weight percent, preferably from 5 to 80 weight percent. Formulations in the form of powders comprise about 1 to 30 weight percent, preferably 5 to 20 weight percent, of active substance; the sprayable solutions are from about 0.05 to 80 weight percent, preferably from 2 to 50 weight percent of active substance. In the case of granules, for example water-dispersible granules, the content of active substance depends partly on whether the active compound is in the liquid or solid form and on the granulation auxiliaries and fillers that are used. As a rule, water-dispersible granules comprise between 1 and 95 weight percent; the granules to spread between 1 and 50%, preferably between 2 and 25%. The baits have an active substance content of between 0.0001 and 10%, with respect to component 1. The use concentration can vary between 0.1 ppm (equivalent to 0.0001 g / liter) and 10,000 ppm (equivalent to 10 g / liter), preferably between 0.5 and 5,000 ppm, particularly between 5 and 1,000 ppm. A mixture that has been shown to be effective comprises the insecticidal component and a mycoinsecticide component, used in a proportion such that the content of component A reaches up to 0.01 and 50%, preferably from 0.1 to 50%; and the amount of the ico-insecticide up to 102 to 10 * 5 spores, preferably 105 to 1012 spores, or between 0.01 g and 1,000 g of the formulated substance. In addition, the active substance formulations comprise, if appropriate, the adhesives, wetting agents, dispersants, emulsifiers, penetrants, solvents, fillers or carriers that are conventional in each case. For use, the formulations which are present in commercially obtainable form, are diluted if appropriate, in a customary manner, for example, using water in the case of wettable powders, emulsifiable concentrates, dispersions and dispersible granules in Water. Preparations in the form of powders or granules for application to the soil or the solutions of spreading and spraying frequently are not further diluted with other inert substances, before use. Component B can be formulated, for example, as described by Prior, C. and co-authors in the Journal of Invertebrale Pathology 52, 66-72 (1988). Preferably, component B is formulated as proposed in P 44 04 702.9. The rate of application of the required mixture varies with external conditions, such as, for example, temperature, humidity and the like. It also depends on the particular field of application and the plant to be treated; and therefore may vary within wide limits. It is between 1 g / ha and 200 g / ha, preferably between 20 g / ha and 100 g / ha, particularly preferably between 40 g / ha and 80 g / ha, in the case of component A (for example, silafluofen) . In the case of the entomopathogenic fungus, it is between 10 g of conidia / ha and 1,000 g of conidia / ha, preferably between 20 g of conidia / ha and 400 g of conidia / ha. 108 to 100 g of conidia of an opathogenic fungus are approximately 1 g. The two components A and B can be applied simultaneously or in succession. It makes sense to carry out the second application after the first one has dried on the plant, in order to avoid undesirable flushing of the first component. The combination of component (A) and entomopathogenic fungi is well tolerated by plants, has a favorable toxicity for warm-blooded species and is suitable for controlling pests of animals in agriculture, particularly insects and arachnids. The synergistic mixture of the two components is active against the normally sensitive and resistant species and against certain stages of development. The compositions according to the invention have an outstanding insecticidal activity against a broad spectrum of economically important pests. Some representatives of the pests that can be controlled with the compositions according to the invention can be mentioned individually, by way of example, but this is not intended to be a limitation to certain species.

The combinations of active substance according to the invention allow insecticidal and acaricidal activity to be obtained in excess of that which is expected based on the activity of the individual components. This increase in activity allows the application regimes of the individual active substances to be considerably reduced. The combination of the active substances can also improve their long-term activity or cause the acceleration of the speed of activity. Said properties are considerably advantageous for the user who will control the insects in practice. They allow insects to be controlled more economically and more quickly, with less work and for longer periods, which means that better yields can be obtained in the population of crop plants. Another increase in activity can be achieved by using so-called feeding or phago-staging attractions, such as, for example, Konsurne (from Pharrnone), ATPlus, yeast, starch, Stirr? P (from Arochern, North America, Inc., USA) and Coax. Although the compositions according to the invention have an outstanding insecticidal and acaricidal activity, the crop plant is not damaged at all. For this reason, the compositions are particularly suitable for cotton, soybeans and rice crops. It is very particularly advantageous to use it in rice and tea culture, because the climatic conditions are particularly advantageous for both products. They are also suitable for controlling pests in coffee, fruit and vegetable production, or in viticulture. The following examples are intended to illustrate the invention without imposing any restrictions: A.- BIOLOGICAL EXAMPLES In all cases, a differentiation was made between the calculated degree and the degree of effectiveness found in the combinations. If the actual damage exceeds the expected damage by calculation, then the activity of the combination is superadditive, that is, there is a synergistic effect. The combinations of active substance according to the invention have an insecticidal activity exceeding that which is expected based on the expected activities of the individual components, when used by themselves. This means that the combinations of active substance are synergistic.
