New synergistic agents for the fight against the insects and the acarina

The biological agents of pest control will often not have an activity sufficient to protect sufficiently the crops of useful plants against pests. Therefore used to date mainly chemical insecticides. In the context of integrated plant protection, it is desired to minimize use of chemicals without crop losses.

By Publication Soper and Al (1974, Agency Entomology, 3, 560 - 562), it is known that the growth of pathogenic fungi insects is inhibited by simultaneous use of insecticides. Admittedly, this depends on the agent used and its quantity, but from the data it is evident that the growth of the fungi is strongly inhibited. Filho and Al (1987, Biologico, 53, 7 - 12, 69 - 70) report that the growth of A Beauveria bassiana is inhibited by different insecticidal. By the booklet of EP 0,668 722, known only that can be used the fungus. A Beauveria bassiana in combination with a endosulphane. The booklet of EP 0,627 165 describes entomopathogenic fungi in combination with insecticides to control cockroaches. The 897 Patent AC 2,086 351 describes the use of entomopathogenic fungi in conjunction with insecticides for termites.

Surprisingly, has hitherto been identified by biological experiments insecticides having a structure entirely different, which have when used in conjunction with spores or particles of a pathogenic fungus insects an extraordinarily effective against a wide spectrum of different insects and acarids.

The objects of the present invention is insecticides and acaricides characterized by an effective content of at least one insecticide from the group of parapyrethroids, the group of nitromethylenes, carbamate group and the group of phenylpyrazoles, in combination with at least one pathogenic fungus insects (component b).

More particularly the invention relates to agents having as mixing partners following insecticides:

Of particular interest with regard to their action against insects is a mixture of Silafluofen and fungi of the genus Acremonium, Acanthomyces, Aschersonia, the Aspergillus, A Beauveria, Culicinomyces, Engyodontium, Funicularis, The Fusarium, Gibellula, Hirsutella, Hymenstilbe, Metarhiziumgenus, Nomuraea, Paeci1omyces, Paraisaria, w 1 willwill eurodesmopora, Polycephalomyces, Pseudogibel1ula, Sorosporella, Fetal, "redescribed", Tetracrium, Tetranacrium, Tilachlidium, of Tolypocladium, and Verticillium-. All these genera are assigned to the division of Deuteromycotes (Samson and Al, "Atlas Entomopathogenic microfungi", 1988, Springer with Accordance).

Of particular interest is the fungi of the genera Hirsutella, Verticillium-, Metarhiziumgenus, Beauveria species, of Paecilomyces and Nomuraea.

In doing so, the content mycoinsecticide can be present in different forms: as the conidiospores, as homogenised, as packets of hyphene, as hyphene fragments, or as a mixture of two or more of the aforementioned forms.

More particularly insecticides and acaricides containing strips fungi A Beauveria bassiana or Metarhiziumgenus anisoplii.

The fungus A Beauveria bassiana has been described by Bassi, A, (1836, C., R CDAA. IBS. 2 Bets, 434 to 436), Domsch, V.H. and Al (190, compendial Soil microfungi 1, 136 to 139) and Samson, T.M., and Al (1988, Atlas Entomopathogenic microfungi, SpringerVerlag, in Berlin) and may be obtained from Mycotech (mound, in Montana, Revenue), Hoechst Schering to AgrEvo GmbH and of Troy science (formerly Fermone TX) (Phoenics, Ariz, Revenue), hereinafter, designates two components a or b also respectively by GI active ingredient.

The mixing ratios of the two components may vary within broad limits. They depend in particular partner's mixture used, stage of development of the pests and climatic conditions.

The object of the invention is also agents which contain the two components a and b to the side of the appropriate formulation auxiliaries.

Combinations of the active ingredients according to the invention may take any form mixed formulations of both components in that one then conventionally with water, that in the form of granules to be applied, or as a tank mix, common by diluting with water the components formulated separately.

On the basis of these formulations, one may also prepare combinations with other pesticidally active materials, such as selective herbicides, and fungicides or selective insecticides, fertilizers and/or growth regulators, for example in the form of finished formulation or as a tank mix.

The components can be formulated in various ways, each function and/or biological parameters chemical-physical indicated. As possibilities of formulation are for example a consideration:

formulations of yeast, starch formulations, wettable powders (WPP), emulsifiable concentrates (ECs), aqueous solutions (LCS), emulsions (an EW), emulsions such as oil-in-water and water-in-oil, and sprayable solutions or emulsions, dispersions of oil or water, suspoemulsions, powders for wetting (DPs), disinfectants, granules to be applied to the soil or spreading, or water dispersable granules (wb), the ULV formulations which, microcapsule, bait (substrates).

Of particular interest is the oil-in-water and water-in-oil, wettable powders or granules.

These different types of formulations are known in principle and described e.g. by Winnacker-to-Küchler, " presterende technology¹ ', the volume 7, the Hauser C Accordance Munich, 4^I phase. , 1986; Valkenburg NAVs, "pesticidal formulation", the Marcel the Dekker, NY, 2^I edit 1972-73;

K Martens on, "Handbook on a spray Through", 3^I editing, G Goodwin's LTE, London.

Formulation auxiliaries which are needed, such as bulking agents, surfactants, solvents and other additives, are also known and described for example by Dayan, "the Handbook of insecticidal dust-Diluents NDA Carrier", 2^I editing, Darland livres, the Caldwell NJ; Η. ν. Olphen, "introducing Tp0.7 Constantinescu Colloid joining technology", 2^I edition, Wiley Interscience J & sounds, Υ Ν.., MCQUIBBAN, "waveguide in solvent", 2^I editing, Interscience, Ν. Υ. 1950;

Accordance the Hauser Munich, 4^I edition, 1986.

Sprayable powders (wettable powders) are preparations which can be dispersed uniformly in water, which still contain at side of the active ingredient, in addition to the diluent or bulking agent, a wetting agent, for example polyethoxylated alkylphenols, fatty alcohols or polyethoxylated fatty amines, of alkane - or alkyl benzene sulfonates and dispersing agents, such as for example sodium lignosulphonate, the 2.2 'dinaphtylméthane-to-6.6' sodium dodecyl diphenyloxide disulfonate, the dibutyl naphthalene-sodium or also 1' oléylméthyltaurinate sodium.

Emulsifiable concentrates are prepared by dissolving the active ingredient in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or else aromatic compounds or hydrocarbons with a high boiling point, by adding one or more emulsifiers. As emulsifiers, can be used for example: calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid esters and polyglycols, of alkylarylpolyglycoléthers, of fatty alcohol ethers and polyglycols, condensation products of propylene oxide-ethylene oxide, of alkylpolyéthers, sorbitan esters of fatty acids, polyoxyethylene esters and sorbitan. and fatty acids, or esters of polyoxyethylene sorbitan.

Dusting powders are obtained by grinding the active substance with finely divided solid materials, for example talc, natural clays such as kaolin, bentonite and pyrophyllite diatomacées earths.

Pellets can be prepared either by spraying the active ingredient by a nozzle on an adsorptive granulated inert material, either by application of the active ingredient concentrates using adhesives, for example poly (vinyl alcohol), sodium polyacrylate or else mineral oils, to the surface of carriers such as sand, kaolinite or granulated inert materials. One may also be granulated to suitable ingredients conventionally for the preparation of fertilizer granules, if desired in a mixture with fertilizers.

Agrochemical preparations generally contain 0.0001 to 99% by weight of the two components a and b, more particularly from 0.0005 to 95%, particularly preferably from 2 to 90%. Concentrations are low, it is to say of 0.0001 to 2% are advantageous in the control of insects socially undesirable, such as offered by the 897 Patent w 44, 03 062, 2.

The formulations may contain different concentrations of active ingredients a and b.

In wettable powders, the active ingredient concentration is 10 to for example about 90% by weight, the remainder to 100% by weight is composed of customary formulation auxiliaries. In the case of emulsifiable concentrates, the active ingredient concentration can be about 1 to 90% by weight, preferably from 5 to 80% by weight. The powder formulations contain from about 1 to 30% by weight, preferably from 5 to 20% by weight of active substance, sprayable solutions approximately 0.05 to 80% by weight, preferably from 2 to 50% by weight, of the active ingredient. In the case of granules, for example of water-dispersible granules, the active substance content depends partly on the liquid or solid form under which comprises the active ingredient, and what granulating aids and loads were used. In general, the content in the case of water dispersable granules is between 1 and 95% by weight, granules for spreading between 1 and 50%, preferably between 2 and 25%. In baits, the active ingredient content in the component 1 is between 0.0001 and 10%.

The application concentration can vary between 0.1 ppm and 10,000 ppm (=0.0001 g/l) (=10 g/l), preferably between 0.5 and 5,000 ppm, more preferably between 5 and 1,000 ppm.

A mixture of the insecticidal component, respectively mycoinsecticide used in such a ratio that the content of the component is between 0.01 and has 50%, preferably 50% to 0.1 of the content and mycoinsecticide for 10² to 1q¹⁵ spore, preferably for 10⁵ to 10¹² spore, between 0.01 g and 1,000 g of substance formulated, has proven effective.

Furthermore, the foregoing formulations of active ingredients optionally contain, as needed, adhesives, wetting agents, dispersants, emulsifiers, penetration agents, solvents, fillers or carriers.

Formulations are utilized available commercially useful form optionally diluted with water in a conventional way, for example in the case of sprayable powders, emulsifiable concentrates, dispersions and water-dispersible granules. In general, only diluted further prior to use with other inert substances the powder preparations, applying ground respectively by spreading, sprayable solutions.

Component b can be formulated for example as described by at Prior, and Al C, in Journal of Invertebrate pathology to, 52, 66 to 72 (1988). Preferably, carried out the formulation of component b according to the description given by the 897 Patent w 44, 04 702, 9.

The applicable amount required of the mixture varies depending on external conditions, such as for example temperature, humidity, and so forth it also depends upon the particular use and the plant to be treated, and thus may vary within broad limits. For the component, (e.g. Silafluofen), it is between 1 gm/ha and 200 grams/acre, preferably between 20 grams/100 grams/ha and as ha, particularly preferably between 40 gm/ha and 80 grams/acre.

For the pathogenic fungus for insects, it is between 10 g of conidia/ha and 1,000 g of conidia/acre, preferably between 20 g of conidia/ha and 400 grams/acre.

10⁸ to 10¹⁰ g of conidia of a pathogenic fungus insects correspond to about 1 gm.

It is possible to apply the two components a and b simultaneously or one after the other. Reasonably, it conduct the second application after the first has dried on the plant, in order to avoid an undesired removal by flushing of the first component.

The combination of component (has) and fungi that are pathogenic to insects (β) is suitable, while retaining good compatibility with plants and favorable for the mammalian toxicity, the control of animal pests, in particular insects and spiders found in agriculture.

The synergistic mixture of the two components acts against types normally susceptible and resistant, as well as against different developmental stages. The agents according to the invention have excellent insecticidal activity against a wide spectrum of important pests in the economy.
