description

New synergistic means to control insects and acarina

Organic pesticides are often insufficient in their potency to adequately protect crops from pests. That is why chemical insecticides are primarily used to this day. Integrated crop protection aims to minimize the use of chemicals without having to accept that crop losses will occur.

From the publication by Soper et al. (1974, Environmental Entomology, 3, 560-562) it is known that the growth of insect pathogenic fungi is inhibited by the simultaneous use of insecticides. Although this depends on the agent used and its amount, it can be seen from the data that the growth of the fungi is severely impaired. Filho et al. (1987, Biologico, 53, 7-12, 69-70) report that the growth of Beauveria bassiana is inhibited by various insecticides. From EP 0668 722 it is only known that the mushroom Beauveria bassiana can be used in combination with endosulfan.

Surprisingly, structurally completely different insecticides have now been identified in biological experiments which, when used together with spores or particles of an insect-pathogenic fungus, show an extraordinarily good activity against a broad spectrum of different insects and acarina.

The present invention relates to insecticidal and acaricidal agents, characterized by an effective content of at least one insecticidal compound selected from the group of the parapyrethroids, the group of the nitromethylenes, the group of the carbamates and the group of the phenylpyrazoles in combination with at least one insect pathogenic fungus (component B). The invention particularly relates to compositions with the following insecticides as mixing partners:

1) Parapyrethroids ("non-ester pyrethroids"), e.g. Silafluofen

(4-ethoxyphenyl- [3- (4-fluoro-3-phenoxyphenyl) propyl] dimethyl silane, formula I, component A1)

and

Etofenprox (2- (4-ethoxyphenyl) -2-methyl-propyl-3-phenoxybenzyl ether, formula II, component A2),

2) Nitromethylenes, e.g.

Imidacloprid (1- (6-chloro-3-pyridylmethyl) -N-nitroimidazolidin-2-ylidenamine, formula III, component A3),

NO,

Cl— < ^{N ~} ) -CH _r NX NH (III) NI25 ((E) -N ¹ - [(6-chloro-3-pyridyl) methyl] -N ² -cyano-N ¹ -methylacetamidine, formula IV, component A4)

and

Nitenpyram ((E) -N- (6-chloro-3-pyridylmethyl) -N-ethyl-N'-methyl-2-nitrovinylidenediamine, formula (V), component A5),

Cl- < ^{N "} Λ -CH ₂ N ^h _v ^2CH3 _H

CH ₃ NH NO-

3) carbamates, e.g.

Fenoxycarb (ethyl 2- (4-phenoxyphenoxy) ethyl carbamate, formula VI, component A6)

4) phenylpryrazoles, e.g.

Fipronil ((+) - 5-amino-1- (2,6-dichloro-α, α, α-trifluoro-p-tolyl) -4-trifluoromethyl-sulfinyl-pyrazole-3-carbonitπ ^' l, formula VII, component A7).

The above compounds are known from the literature ("Pesticide Manual", 10th edition Brit. Crop. Prot. Council, 1994) and are commercially available.

Of particular interest in their action against insects is a mixture of silafluofen and fungi of the genera Acremonium, Acanthomyces, Aschersonia, Aspergillus, Beauveria, Culicinomyces, Engyodontium, Funicularis, Fusarium, Gibellula, Hirsuteila, Hymenstilbe, Metarharia, Puraureale, Paracilmia, Paec , Polycephalomyces, Pseudogibellula, Sorosporella, Sporothrix, "Stilbella", Tetracrium, Tetranacrium, Tilachlidium, Tolypocladium, and Verticillium. All of these genera are assigned to the department of Deuteromycota (Samson et al., "Atlas of Entomopathogenic Fungi, 1988, Springer Verlag).

Mushrooms of the genera Hirsuteila, Verticillium, Metarhician, Beauveria, Paecilomyces and Nomuraea are of particular interest.

The proportion of mycoinsecticides can be present in various forms: as conidiospores, as blastospores, as hyphal packets, as hyphal fragments or as a mixture of two or more of the listed forms.

The invention relates in particular to insecticidal and acaricidal compositions which contain the fungus Beauveria bassiana or Metarhistall anisoplii.

The mushroom Beauveria bassiana was developed by Bassi, A. (1836, CR Acad. Sci. Paris 2, 434 to 436), Domsch, VH et al. (190, Compendium of Soil Fungi 1, 136 to 139) and Samson, RA et al. (1988, Atlas of Entomopathogenic Fungi, Springer-Verlag, Berlin) and is available from Mycotech (Butte, Montana, USA), Hoechst Schering AgrEvo GmbH and Troy Sciences (formerly Fermone Corp.) (Phoenix, Arizona, USA) . In the following, the term active ingredient is also used for the two components A or B. The mixing ratios of the two components can fluctuate within wide limits. They are particularly dependent on the mixture partner used, the stage of development of the pests and the climatic conditions.

The invention also relates to compositions which contain the two components A and B in addition to suitable formulation auxiliaries.

The active compound combinations according to the invention can be present both as mixed formulations of the two components, which are then diluted in the customary manner with water or as granules, or as so-called tank mixtures by diluting the separately formulated components with water.

Based on these formulations, combinations with other pesticidally active substances, such as selective herbicides, and specific fungicides or insecticides, as well as fertilizers and / or growth regulators, e.g. in the form of a finished formulation or as a tank mix.

The components can be formulated in various ways, depending on which biological and / or chemical-physical parameters are specified. Examples of possible formulations are: yeast formulations, starch formulations, wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions (EW) such as oil-in-water and water-in-oil emulsions, sprayable solutions or Emulsions, oil or water-based dispersions, suspoemulsions, dusts (DP), mordants, granules for soil or litter application or water-dispersible granules (WG), ULV formulations, microcapsules, baits (substrates).

Oil-in-water and water-in-oil emulsions, wettable powders or granules are of particular interest. These individual formulation types are known in principle and are described, for example, in: Winnacker-Küchler, "Chemical Technology", Volume 7, C. Hauser Verlag Munich, 4th Edition 1986; van Valkenburg, "Pesticides Formulations", Marcel Dekker NY, 2nd edition 1972-73; K. Martens, "Spray Drying Handbook", 3rd Edition, G. Goodwin Ltd. London.

The necessary formulation aids such as inert materials, surfactants, solvents and other additives are also known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd edition, Darland Books, Caldwell NJ; H. v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd edition, J. Wiley & Sons, NY, Marsden, "Solvente Guide", 2nd edition, Interscience, NY 1950; McCutcheon ^'s , Detergents and Emulsifiers Annual, MC Publ. Corp., Ridgewood NJ; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., NY 1964; Schönfeldt, "Interface-active ethylene oxide adducts", Wiss. Publishing company, Stuttgart 1976; Winnacker-Küchler, "Chemical Technology", Volume 7, C. Hauser Verlag Munich, 4th ed. 1986.

Spray powders (wettable powders) are preparations which are uniformly dispersible in water and which, in addition to the active ingredient, also contain wetting agents, e.g. polyoxethylated alkylphenols, polyoxethylated fatty alcohols or fatty amines, alkane or alkylbenzenesulfonates and dispersants, e.g. sodium lignosulfonate, 2,2'-dinaphthylmethane-6,6'-disulfonic acid sodium, dibutylnaphthalene sulfonic acid sodium or also oleoylmethyl tauric acid sodium.

Emulsifiable concentrates are prepared by dissolving the active ingredient in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or else higher-boiling aromatics or hydrocarbons, with the addition of one or more emulsifiers. Examples of emulsifiers which can be used are: alkylarylsulfonic acid calcium salts such as calcium dodecylbenzenesulfonate or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, Propylene oxide-ethylene oxide condensation products, alkyl polyether, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester or polyoxethylene sorbitol ester.

Dusts are obtained by grinding the active ingredient with finely divided solid substances, e.g. Talc, natural clays such as kaolin, bentonite and pyrophyllite or diatomaceous earth.

Granules can either be produced by spraying the active ingredient onto adsorbable, granulated inert material or by applying active ingredient concentrates by means of adhesives, e.g. Polyvinyl alcohol, sodium polyacrylic acid or mineral oils, on the surface of carriers such as sand, kaolinite or granulated inert material. Suitable active ingredients can also be granulated in the manner customary for the production of fertilizer granules, if desired in a mixture with fertilizers.

The agrochemical preparations generally contain 0.0001 to 99 percent by weight of the two components A and B, in particular between 0.0005 and 95%, particularly preferably between 2 and 90%. The low concentrations, i.e. 0.0001 to 2% are advantageously used to control unwanted social insects, as was proposed in P 44 03 062.2.

The concentrations of active ingredients A and B can differ in the formulations.

The active ingredient concentration in wettable powders is, for example, about 10 to 90% by weight, the remainder to 100% by weight consists of customary formulation components. In the case of emulsifiable concentrates, the active substance concentration can be approximately 1 to 90% by weight, preferably 5 to 80% by weight. Dust-like formulations contain about 1 to 30% by weight, preferably 5 to 20% by weight of active ingredient, sprayable solutions about 0.05 to 80% by weight, preferably 2 to 50% by weight of active ingredient. In the case of granules, for example water-dispersible granules, the active ingredient content depends on Part of it depends on whether the active compound is liquid or solid and which granulating aids and fillers are used. As a rule, the content of the water-dispersible granules is between 1 and 95% by weight, for scattering granules between 1 and 50%, preferably between 2 and 25%. In the case of baits, the active ingredient content for component 1 is between 0.0001 and 10%.

The application concentration can vary between 0.1 ppm (± 0.0001 g / l) and 10,000 ppm (- 0 g / l), preferably between 0.5 and 5,000 ppm, particularly preferably between 5 and 1000 ppm.

A mixture which consists of the insecticide component or mycoinsecticide component used in a ratio has proven to be effective, so that the content of component A is between 0.01 and 50%, preferably 0.1 to 50%, and the mycoinsecticide content is 10 ² to 10 ¹⁵ spores, preferably 10 ⁵ to 10 ¹² spores or between 0.01 g and 1000 g of formulated substance.

In addition, the active ingredient formulations mentioned may contain the customary adhesives, wetting agents, dispersants, emulsifiers, penetrants, solvents, fillers or carriers.

For use, the formulations present in the commercial form are optionally diluted in the customary manner, e.g. in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules using water. Preparations in the form of dust, ground granules or scattering granules and sprayable solutions are usually no longer diluted with other inert substances before use.

Component B can e.g. as described by Prior, C. et al. in the Journal of Invertebrate Pathology 52, 66 to 72 (1988). Component B is preferably formulated as proposed in P 44 04 702.9.

The required application rate of the mixture varies with the external conditions, such as temperature, humidity and others. It is also from the respective Application area and the plant to be treated and can therefore vary within wide limits. For component A (for example silafluofen) 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.

For the insect pathogenic fungus, it is between 10 g conidia / ha and 1000 g conidia / ha, preferably between 20 g conidia / ha and 400 g / ha.

10 ⁸ to 10 ¹⁰ g conidia of an insect pathogenic fungus correspond to about 1 g.

The two components A and B can be applied simultaneously or successively. It is advisable to carry out the second application after the first application has dried on the plant in order to avoid undesired rinsing off of the first component.

The combination of component (A) and the insect-pathogenic fungi (B) is suitable for combating animal pests, in particular insects and arachnids, which occur in agriculture, with good plant tolerance and favorable warm-blood toxicity.

The synergistic mixture of the two components works against normally sensitive and resistant species as well as individual stages of development. The compositions according to the invention have excellent insecticidal activity against a broad spectrum of economically important pests. Some representatives of the pests may be mentioned in detail by way of example, which can be controlled by the agents according to the invention without the name being intended to restrict them to certain species.

With the active ingredient combinations according to the invention, an insecticidal and acaricidal action is achieved which goes beyond what is due to the action of the individual components is to be expected. These increases in effectiveness make it possible to significantly reduce the amounts used for the individual active ingredients. The combination of the active ingredients can also improve their long-term effectiveness or accelerate the rate of action. Such properties offer the user considerable advantages in practical insect control. It can control insects more cheaply, more quickly, with less workload and more permanently, thereby harvesting more crops.

A further increase in activity can be achieved by so-called "feeding attractants" or phagostimulants, such as Achieve consumption (from Pharmone), ATPIus, yeast, starch, Stirrup (from Atochem. North America Inc., USA) and coax.

Although the compositions according to the invention have excellent insecticidal and acaricidal activity, the crop is not harmed at all. For these reasons, the agents are particularly suitable in crops of cotton, soybeans and rice. The application in rice and tea cultures is particularly useful because the climatic conditions are particularly advantageous for both products. They are also suitable for controlling pests in coffee, fruit and vegetable cultivation or even viticulture.

The following examples serve to illustrate the invention, without being restricted thereto:

A. Biological examples

In all cases, a distinction was made in the combinations between the calculated and the found efficiency.

If the actual damage is greater than the expected damage, the effect of the combination is more than additive, ie there is a synergistic effect. The active compound combinations according to the invention have an insecticidal action which is higher than is to be expected on the basis of the observed effects of the individual components when used alone. The Active ingredient combinations are therefore synergistic.

The effect of the individual components or the individual component mixtures was assessed 6 days after storage at 25 ° C. and 80% relative atmospheric humidity.

Example 2: Anthomomus grandis in combination with silafluofen

Adult cotton beetles (Anthonomus grandis) were sprayed with active ingredients or their mixtures together with the appropriate feed material (synthetic feed). The effect of the individual components or the individual component mixtures was assessed 9 days after storage at 25 ° C. and 90% relative atmospheric humidity.

Example 3: Nilaparvata lugens in combination with silafluofen

Larvae of the leafhopper (Nilaparvata lugens) were placed on rice plants which had previously been immersed in aqueous solutions consisting of active ingredients or mixtures thereof. The effect of the individual components or the individual component mixtures was assessed 6 days after storage at 25 ° C. and 80% relative atmospheric humidity.
