The present invention relates to a pesticidal mixture comprising as active compounds at least one pyrazole compound and at least one further pesticide. Furthermore, the invention relates to methods of applying said mixture.
The present invention thus relates to pesticidal mixtures comprising as active compounds
wherein
One typical problem arising in the field of pest control lies in the need to reduce the dosage rates of the active ingredient in order to reduce or avoid unfavorable environmental or toxicological effects whilst still allowing effective pest control. Another problem encountered concerns the need to have available pest control agents which are effective against a broad spectrum of pests.
Another difficulty in relation to the use of pesticides is that the repeated and exclusive application of an individual pesticidal compound leads in many cases to a rapid selection of pests which have developed natural or adapted resistance against the active compound in question. Therefore there is a need for pest control agents that help prevent or overcome resistance.
WO 2012/143317 and WO2015/055497 describe N-pyridazinyl carboxamide compounds derived from pyrazole carboxylic acids. These compounds are mentioned to be useful for combating in-vertebrate pests.
It is therefore an object of the present invention to provide pesticidal mixtures and/or compounds which solves at least one of the discussed problems as reducing the dosage rate, enhancing the spectrum of activity or combining knock-down activity with prolonged control or as to resistance management.
It has been found that at least one of these objectives is achieved by the combination of active compounds defined in the outset.
Moreover, it has also been found that simultaneous, that is joint or separate, application of one or more active compounds A and one or more active compounds B or successive application of one or more active compounds A and one or more active compounds B allows enhanced control of pests compared to the control rates that are possible with the individual compounds.
Moreover, the present invention relates to
The mixture according to the invention may be a physical mixture of the at least one compound A and the at least one compound B. Accordingly, the invention also provides a mixture comprising at least one compound A and at least one compound B. However, the composition may also be any combination of at least one compound A with at least one compound B, it not being required for compounds A and B to be present together in the same formulation.
An example of a composition according to the invention or to be used according to the invention in which the at least one compound A and the at least one compound B are not present together in the same formulation is a combipack. In a combipack, two or more components of a combipack are packaged separately, i.e., not jointly pre-formulated. As such, combipacks include one or more separate containers such as vials, cans, bottles, pouches, bags or canisters, each container containing a separate component for an agrochemical composition. One example is a two-component combipack. Accordingly the present invention also relates to a two-component combipack, comprising a first component which in turn comprises at least one compound A, a liquid or solid carrier and, if appropriate, at least one surfactant and/or at least one customary auxiliary, and a second component which in turn comprises at least one compound B, a liquid or solid carrier and, if appropriate, at least one surfactant and/or at least one customary auxiliary. More details, e.g. as to suitable liquid and solid carriers, surfactants and customary auxiliaries are described below.
The “combined” use of at least one pyrazole compound A “in combination with” at least one compound B on the one hand can be understood as using a physical mixture of at least one pyrazole compound A and at least one compound B. On the other hand, the combined use may also consist in using the at least one pyrazole compound A and the at least one compound B separately, but within a sufficiently short time of one another so that the desired effect can take place. More detailed illustrations of the combined use can be found in the specifications below.
The term “invertebrate pest” (also referred to as animal pests) as used herein encompasses animal populations, such as insects, arachnids and nematodes, which may attack plants, thereby causing substantial damage to the plants attacked, as well as ectoparasites which may infest animals, in particular warm blooded animals such as e.g. mammals or birds, or other higher animals such as reptiles, amphibians or fish, thereby causing substantial damage to the animals infested.
The term “compound(s) according to the invention”, or “compound(s) of formula I” or “pyrazole compound(s) A” comprises the compound(s) as defined herein as well as a stereoisomer, salt, tautomer or N-oxide thereof. The term “compound(s) of the present invention” is to be understood as equivalent to the term “compound(s) according to the invention”, therefore also comprising a stereoisomer, salt, tautomer or N-oxide thereof.
The term “stereoisomers” encompasses both optical isomers, such as enantiomers or diastereomers, the latter existing due to more than one center of chirality in the molecule, as well as geometrical isomers (cis/transisomers).
Depending on the substitution pattern, the compounds of formula I may have one or more centers of chirality, in which case they are present as mixtures of enantiomers or diastereomers.
One center of chirality is the carbon atom carrying radicals R3 and R4. The invention provides both the pure enantiomers or diastereomers and their mixtures and the use according to the invention of the pure enantiomers or diastereomers of the compound I or its mixtures. Suitable compounds of the formula I also include all possible geometrical stereoisomers (cis/trans isomers) and mixtures thereof.
The term “N-oxide” relates to a form of compounds I in which at least one nitrogen atom is present in oxidized form (as NO).
The compounds of the invention may be amorphous or may exist in one or more different crystalline states (polymorphs) which may have a different macroscopic properties such as stability or show different biological properties such as activities. The present invention includes both amorphous and crystalline compounds of the formula I, mixtures of different crystalline states of the respective compound I, as well as amorphous or crystalline salts thereof.
Salts of the compounds of the formula I are preferably agriculturally and veterinarily acceptable salts. They can be formed in a customary method, e.g. by reacting the compound with an acid of the anion in question if the compound of formula I has a basic functionality or by reacting an acidic compound of formula I with a suitable base.
Suitable agriculturally acceptable salts are especially the salts of those cations or the acid addition salts of those acids whose cations and anions, respectively, do not have any adverse effect on the action of the compounds according to the present invention. Suitable cations are in particular the ions of the alkali metals, preferably lithium, sodium and potassium, of the alkaline earth metals, preferably calcium, magnesium and barium, and of the transition metals, preferably manganese, copper, zinc and iron, and also ammonium (NH4+) and substituted ammonium in which one to four of the hydrogen atoms are replaced by C1-C4-alkyl, C1-C4-hydroxyalkyl, C1-C4-alkoxy, C1-C4-alkoxy-C1-C4-alkyl, hydroxy-C1-C4-alkoxy-C1-C4-alkyl, phenyl or benzyl. Examples of substituted ammonium ions comprise methylammonium, isopropylammonium, dimethylammonium, diisopropylammonium, trimethylammonium, tetramethylammonium, tetraethylammonium, tetrabutylammonium, 2-hydroxyethylammonium, 2-(2-hydroxyethoxy)ethylammonium, bis(2-hydroxyethyl)ammonium, benzyltrimethylammonium and benzl-triethylammonium, furthermore phosphonium ions, sulfonium ions, preferably tri(C1-C4-alkyl)sulfonium, and sulfoxonium ions, preferably tri(C1-C4-alkyl)sulfoxonium.
Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogen sulfate, sulfate, dihydrogen phosphate, hydrogen phosphate, phosphate, nitrate, hydrogen carbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate, and the anions of C1-C4-alkanoic acids, preferably formate, acetate, propionate and butyrate. They can be formed by reacting a compound of formulae I with an acid of the corresponding anion, preferably of hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid or nitric acid.
The organic moieties mentioned in the above definitions of the variables are—like the term halogen—collective terms for individual listings of the individual group members. The prefix Cn-Cm indicates in each case the possible number of carbon atoms in the group.
The commercially available further compounds B may be found in The Pesticide Manual, 17th Edition, British Crop Protection Council (2015) among other publications, and its online database https://www.bcpc.org/product/bcpc-online-pesticide-manual-latest-version. Compounds A2, B1, B2, and B3, resp., and their pesticidal action are known from WO 2013/050302, WO 2014/122083, WO 2014/125651, and WO 2015/190316, resp.
We have found that simultaneous, that is joint or separate, application of at least one compound I and at least one compound B or successive application of at least one of the compound(s) of formula I and at least one compound B allows better control of animal pests than is possible with the individual compounds alone (synergistic mixtures).
The compounds of formula I can be used as synergists for a large number of different fungicidal active compounds. By simultaneous, that is joint or separate, application of compound(s) of formula I with at least one active compound B, the fungicidal and/or insecticidal activity, resp., is increased in a superadditive manner.
The compounds of the formula I can be present in different crystal modifications, which may differ in biological activity.

In the context of the present invention, the term plant refers to an entire plant, a part of the plant or the plant propagation material.
The mixtures of the present invention and the compositions comprising them are particularly important in the control of a multitude of insects on various cultivated plants.
Plants which can be treated with the inventive mixtures include all genetically modified plants or transgenic plants, e.g. crops which tolerate the action of herbicides or fungicides or insecticides owing to breeding, including genetic engineering methods, or plants which have modified characteristics in comparison with existing plants, which can be generated for example by traditional breeding methods and/or the generation of mutants, or by recombinant procedures.
The term “plant propagation material” is to be understood to denote all the generative parts of the plant such as seeds and vegetative plant material such as cuttings and tubers (e. g. potatoes), which can be used for the multiplication of the plant. This includes seeds, roots, fruits, tubers, bulbs, rhizomes, shoots, sprouts and other parts of plants. Seedlings and young plants, which are to be transplanted after germination or after emergence from soil, may also be mentioned. These young plants may also be protected before transplantation by a total or partial treatment by immersion or pouring.
The term “cultivated plants” is to be understood as including plants which have been modified by breeding, mutagenesis or genetic engineering. Genetically modified plants are plants, which genetic material has been so modified by the use of recombinant DNA techniques that under natural circumstances cannot be obtained by cross breeding, mutations or natural recombination. Typically, one or more genes have been integrated into the genetic material of a genetically modified plant in order to improve certain properties of the plant.
The term “cultivated plants” is to be understood also including plants that have been rendered tolerant to applications of specific classes of herbicides, such as hydroxy-phenylpyruvate dioxygenase (HPPD) inhibitors; acetolactate synthase (ALS) inhibitors, such as sulfonyl ureas (see e. g. U.S. Pat. No. 6,222,100, WO 01/82685, WO 00/26390, WO 97/41218, WO 98/02526, WO 98/02527, WO 04/106529, WO 05/20673, WO 03/14357, WO 03/13225, WO 03/14356, WO 04/16073) or imidazolinones (see e. g. U.S. Pat. No. 6,222,100, WO 01/82685, WO 00/26390, WO 97/41218, WO 98/02526, WO 98/02527, WO 04/106529, WO 05/20673, WO 03/14357, WO 03/13225, WO 03/14356, WO 04/16073); enolpyruvylshikimate-3-phosphate synthase (EPSPS) inhibitors, such as glyphosate (see e. g. WO 92/00377); glutamine synthetase (GS) inhibitors, such as glufosinate (see e. g. EP-A 242 236, EP-A 242 246) or oxynil herbicides (see e. g. U.S. Pat. No. 5,559,024) as a result of conventional methods of breeding or genetic engineering. Several cultivated plants have been rendered tolerant to herbicides by conventional methods of breeding (mutagenesis), for example Clearfield® summer rape (Canola) being tolerant to imidazolinones, e. g. imazamox. Genetic engineering methods have been used to render cultivated plants, such as soybean, cotton, corn, beets and rape, tolerant to herbicides, such as glyphosate and glufosinate, some of which are commercially available under the trade names RoundupReady® (glyphosate) and LibertyLink® (glufosinate).
The term “cultivated plants” is to be understood also including plants that are by the use of recombinant DNA techniques capable to synthesize one or more insecticidal proteins, especially those known from the bacterial genus Bacillus, particularly from Bacillus thuringiensis, such as δ-endotoxins, e. g. CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c; vegetative insecticidal proteins (VIP), e. g. VIP1, VIP2, VIP3 or VIP3A; insecticidal proteins of bacteria colonizing nematodes, for example Photorhabdus spp. or Xenorhabdus spp.; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins, or other insect-specific neurotoxins; toxins produced by fungi, such Streptomycetes toxins, plant lectins, such as pea or barley lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin or papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroid oxidase, ecdysteroid-IDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors or HMG-CoA-reductase; ion channel blockers, such as blockers of sodium or calcium channels; juvenile hormone esterase; diuretic hormone receptors (helicokinin receptors); stilben synthase, bibenzyl synthase, chitinases or glucanases.

The present invention is now illustrated in further details by the following examples.
Synergism can be described as an interaction where the combined effect of two or more compounds is greater than the sum of the individual effects of each of the compounds. The presence of a synergistic effect in terms of percent control or efficiacy, between two mixing partners (X and Y) can be calculated using the Colby equation (Colby, S. R., 1967, Calculating Synergistic and Antagonistic Responses in Herbicide Combinations, Weeds, 15, 20-22):
When the observed combined control effect is greater than the expected combined control effect (E), then the combined effect is synergistic.
The following tests can demonstrate the control efficacy of mixtures or compositions of this invention on specific pests and fungi. However, the pest control protection afforded by the compounds, mixtures or compositions is not limited to these species. In certain instances, combinations of a compound of this invention with other invertebrate pest control compounds or agents are found to exhibit synergistic effects against certain important invertebrate pests and/or harmful fungi.
The expected efficacies of active compound mixtures were determined using Colby's formula [R. S. Colby, “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, 20-22 (1967)] and compared with the observed efficacies.
