In addition, component B may be a nematicidally active biological agent. The nematicidally active biological agent refers to any biological agent that has nematicidal activity. The biological agent can be any type known in the art including bacteria and fungi. The wording “nematicidally active” refers to having an effect on, such as reduction in damage caused by, agricultural-related nematodes. The nematicidally active biological agent can be a bacterium or a fungus. Preferably, the biological agent is a bacterium. Examples of nematicidally active bacteria include Bacillus firmus, Bacillus cereus, Bacillus subtilis, and Pasteuria penetrans, preferably Bacillus firmus, Bacillus subtilis, and Pasteuria penetrans. A suitable Bacillus firmus strain is strain CNCM I-1582 which is commercially available as BioNem™. A suitable Bacillus cereus strain is strain CNCM I-1562. Of both Bacillus strains more details can be found in U.S. Pat. No. 6,406,690.
It has now been found, surprisingly, that the active ingredient mixture according to the invention not only delivers about the additive enhancement of the spectrum of action with respect to the pest to be controlled that was in principle to be expected but achieves a synergistic effect which can extend the range of action of the component A and of the component B in two ways. Firstly, the rates of application of the component A and of the component B are lowered whilst the action remains equally good. Secondly, the active ingredient mixture still achieves a high degree of pest control, sometimes even where the two individual components have become totally ineffective in such a low application rate range. This allows increased safety in use.
However, besides the actual synergistic action with respect to pest control, the pesticidal compositions according to the invention can have further surprising advantageous properties which can also be described, in a wider sense, as synergistic activity. Examples of such advantageous properties that may be mentioned are: a broadening of the spectrum of pest control to other pests, for example to resistant strains; a reduction in the rate of application of the active ingredients; adequate pest control with the aid of the compositions according to the invention, even at a rate of application at which the individual compounds are totally ineffective; advantageous behaviour during formulation and/or upon application, for example upon grinding, sieving, emulsifying, dissolving or dispensing; increased storage stability; improved stability to light; more advantageuos degradability; improved toxicological and/or ecotoxicological behaviour; improved characteristics of the useful plants including: emergence, crop yields, more developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf colour, less fertilizers needed, less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, improved plant vigor, and early germination; or any other advantages familiar to a person skilled in the art.
The compounds of formula I and their manufacturing processes are known from WO 2009/080250. The components B are known, e.g. from “The Pesticide Manual”, Fifteenth Edition, Edited by Clive Tomlin, British Crop Protection Council. The compound under y) is known from DE 102006015467. Reference to the above components B includes reference to their salts and any usual derivatives, such as ester derivatives.
The combinations according to the invention may also comprise more than one of the active components B, if, for example, a broadening of the spectrum of pest control is desired. For instance, it may be advantageous in the agricultural practice to combine two or three components B with any of the compounds of formula I, or with any preferred member of the group of compounds of formula I. The mixtures of the invention may also comprise other active ingredients in addition to components A and B. In other embodiments the mixtures of the invention may include only components A and B as pesticidally active ingredients, e.g. no more than two pesticidally active ingredients.

The mixtures of the invention are particularly effective against insects, acarines and/or nematodes.
According to the invention “useful plants” typically comprise the following species of plants: grape vines; cereals, such as wheat, barley, rye or oats; beet, such as sugar beet or fodder beet; fruits, such as pomes, stone fruits or soft fruits, for example apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries or blackberries; leguminous plants, such as beans, lentils, peas or soybeans; oil plants, such as rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans or groundnuts; cucumber plants, such as marrows, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruit or mandarins; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, cucurbits or paprika; lauraceae, such as avocados, cinnamon or camphor; maize; tobacco; nuts; coffee; sugar cane; tea; vines; hops; durian; bananas; natural rubber plants; turf or ornamentals, such as flowers, shrubs, broad-leaved trees or evergreens, for example conifers. This list does not represent any limitation.
The term “useful plants” is to be understood as including also useful plants that have been rendered tolerant to herbicides like bromoxynil or classes of herbicides (such as, for example, HPPD inhibitors, ALS inhibitors, for example primisulfuron, prosulfuron and trifloxysulfuron, EPSPS (5-enol-pyrovyl-shikimate-3-phosphate-synthase) inhibitors, GS (glutamine synthetase) inhibitors) as a result of conventional methods of breeding or genetic engineering. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding (mutagenesis) is Clearfield® summer rape (Canola). Examples of crops that have been rendered tolerant to herbicides or classes of herbicides by genetic engineering methods include glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady®, Herculex I® and LibertyLink®.
The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.
Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins, for example insecticidal proteins from Bacillus cereus or Bacillus popliae; or insecticidal proteins from Bacillus thuringiensis, such as δ-endotoxins, e.g. CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c, or vegetative insecticidal proteins (VIP), e.g. VIP1, VIP2, VIP3 or VIP3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins, such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsine inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases.
In the context of the present invention there are to be understood by δ-endotoxins, for example CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c, or vegetative insecticidal proteins (VIP), for example VIP1, VIP2, VIP3 or VIP3A, expressly also hybrid toxins, truncated toxins and modified toxins. Hybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). An example for a truncated toxin is a truncated CryIA(b), which is expressed in the Btl 1 maize from Syngenta Seed SAS, as described below. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of CryIIIA055, a cathepsin-D-recognition sequence is inserted into a CryIIIA toxin (see WO 03/018810)
Examples of such toxins or transgenic plants capable of synthesising such toxins are disclosed, for example, in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073.
The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. CryI-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP-A-0 367 474, EP-A-0 401 979 and WO 90/13651.
The toxin contained in the transgenic plants imparts to the plants tolerance to harmful insects. Such insects can occur in any taxonomic group of insects, but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and butterflies (Lepidoptera).
Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available. Examples of such plants are: YieldGard® (maize variety that expresses a CryIA(b) toxin); YieldGard Rootworm® (maize variety that expresses a CryIIIB(b1) toxin); YieldGard Plus® (maize variety that expresses a CryIA(b) and a CryIIIB(b1) toxin); Starlink® (maize variety that expresses a Cry9(c) toxin); Herculex I® (maize variety that expresses a CryIF(a2) toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a CryIA(c) toxin); Bollgard I® (cotton variety that expresses a CryIA(c) toxin); Bollgard II® (cotton variety that expresses a CryIA(c) and a CryIIA(b) toxin); VIPCOT® (cotton variety that expresses a VIP toxin); NewLeaf® (potato variety that expresses a CryIIIA toxin); NatureGard® and Protecta®.

Transgenic crops of insect-resistant plants are also described in BATS (Zentrum für Biosicherheit and Nachhaltigkeit, Zentrum BATS, Clarastrasse 13, 4058 Basel, Switzerland) Report 2003, (http://bats.ch).
The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising antipathogenic substances having a selective action, such as, for example, the so-called “pathogenesis-related proteins” (PRPs, see e.g. EP-A-0 392 225). Examples of such antipathogenic substances and transgenic plants capable of synthesising such antipathogenic substances are known, for example, from EP-A-0 392 225, WO 95/33818, and EP-A-0 353 191. The methods of producing such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above.
Antipathogenic substances which can be expressed by such transgenic plants include, for example, ion channel blockers, such as blockers for sodium and calcium channels, for example the viral KP1, KP4 or KP6 toxins; stilbene synthases; bibenzyl synthases; chitinases; glucanases; the so-called “pathogenesis-related proteins” (PRPs; see e.g. EP-A-0 392 225); antipathogenic substances produced by microorganisms, for example peptide antibiotics or heterocyclic antibiotics (see e.g. WO 95/33818) or protein or polypeptide factors involved in plant pathogen defence (so-called “plant disease resistance genes”, as described in WO 03/000906).
Useful plants of elevated interest in connection with present invention are cereals; soybean; rice; oil seed rape; pome fruits; stone fruits; peanuts; coffee; tea; strawberries; turf; vines and vegetables, such as tomatoes, potatoes, cucurbits and lettuce.
The term “locus” of a useful plant as used herein is intended to embrace the place on which the useful plants are growing, where the plant propagation materials of the useful plants are sown or where the plant propagation materials of the useful plants will be placed into the soil. An example for such a locus is a field, on which crop plants are growing.
The term “plant propagation material” is understood to denote generative parts of a plant, such as seeds, which can be used for the multiplication of the latter, and vegetative material, such as cuttings or tubers, for example potatoes. There may be mentioned for example seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes and parts of plants. Germinated plants and young plants which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion. Preferably “plant propagation material” is understood to denote seeds. Insecticides that are of particular interest for treating seeds include thiamethoxam, imidacloprid and clothianidin. Accordingly, in one embodiment component B is selected from thiamethoxam, imidacloprid and clothianidin.
A further aspect of the instant invention is a method of protecting natural substances of plant and/or animal origin, which have been taken from the natural life cycle, and/or their processed forms against attack of pests, which comprises applying to said natural substances of plant and/or animal origin or their processed forms a combination of components A and B in a synergistically effective amount.
According to the instant invention, the term “natural substances of plant origin, which have been taken from the natural life cycle” denotes plants or parts thereof which have been harvested from the natural life cycle and which are in the freshly harvested form. Examples of such natural substances of plant origin are stalks, leafs, tubers, seeds, fruits or grains. According to the instant invention, the term “processed form of a natural substance of plant origin” is understood to denote a form of a natural substance of plant origin that is the result of a modification process. Such modification processes can be used to transform the natural substance of plant origin in a more storable form of such a substance (a storage good). Examples of such modification processes are pre-drying, moistening, crushing, comminuting, grounding, compressing or roasting. Also falling under the definition of a processed form of a natural substance of plant origin is timber, whether in the form of crude timber, such as construction timber, electricity pylons and barriers, or in the form of finished articles, such as furniture or objects made from wood.
According to the instant invention, the term “natural substances of animal origin, which have been taken from the natural life cycle and/or their processed forms” is understood to denote material of animal origin such as skin, hides, leather, furs, hairs and the like.
A preferred embodiment is a method of protecting natural substances of plant origin, which have been taken from the natural life cycle, and/or their processed forms against attack of pests, which comprises applying to said natural substances of plant and/or animal origin or their processed forms a combination of components A and B in a synergistically effective amount.
A further preferred embodiment is a method of protecting fruits, preferably pomes, stone fruits, soft fruits and citrus fruits, which have been taken from the natural life cycle, and/or their processed forms, which comprises applying to said fruits and/or their processed forms a combination of components A and B in a synergistically effective amount.

The amount of a combination of the invention to be applied, will depend on various factors, such as the compounds employed; the subject of the treatment, such as, for example plants, soil or seeds; the type of treatment, such as, for example spraying, dusting or seed dressing; the purpose of the treatment, such as, for example prophylactic or therapeutic; the type of pest to be controlled or the application time.
The mixtures comprising a compound of formula I, e.g. those selected from table A, and one or more active ingredients as described above can be applied, for example, in a single “ready-mix” form, in a combined spray mixture composed from separate formulations of the single active ingredient components, such as a “tank-mix”, and in a combined use of the single active ingredients when applied in a sequential manner, i.e. one after the other with a reasonably short period, such as a few hours or days. The order of applying the compounds of formula I selected from table A and the active ingredients as described above is not essential for working the present invention.
The synergistic activity of the combination is apparent from the fact that the pesticidal activity of the composition of A+B is greater than the sum of the pesticidal activities of A and B.
The method of the invention comprises applying to the useful plants, the locus thereof or propagation material thereof in admixture or separately, a synergistically effective aggregate amount of a component A and a component B.
Some of said combinations according to the invention have a systemic action and can be used as foliar, soil and seed treatment pesticides.
With the combinations according to the invention it is possible to inhibit or destroy the pests which occur in plants or in parts of plants (fruit, blossoms, leaves, stems, tubers, roots) in different useful plants, while at the same time the parts of plants which grow later are also protected from attack by pests.
The combinations of the present invention are of particular interest for controlling pests in various useful plants or their seeds, especially in field crops such as potatoes, tobacco and sugarbeets, and wheat, rye, barley, oats, rice, maize, lawns, cotton, soybeans, oil seed rape, pulse crops, sunflower, coffee, sugarcane, fruit and ornamentals in horticulture and viticulture, in vegetables such as cucumbers, beans and cucurbits.
The combinations according to the invention are applied by treating the pests, the useful plants, the locus thereof, the propagation material thereof, the natural substances of plant and/or animal origin, which have been taken from the natural life cycle, and/or their processed forms, or the industrial materials threatened by pests, attack with a combination of components A and B in a synergistically effective amount.
The combinations according to the invention may be applied before or after infection or contamination of the useful plants, the propagation material thereof, the natural substances of plant and/or animal origin, which have been taken from the natural life cycle, and/or their processed forms, or the industrial materials by the pests.
The combinations according to the invention can be used for controlling, i.e. containing or destroying, pests of the abovementioned type which occur on useful plants in agriculture, in horticulture and in forests, or on organs of useful plants, such as fruits, flowers, foliage, stalks, tubers or roots, and in some cases even on organs of useful plants which are formed at a later point in time remain protected against these pests.
When applied to the useful plants the compound of formula I is generally applied at a rate of 1 to 500 g a.i./ha in association with 1 to 2000 g a.i./ha, of a compound of component B, depending on the class of chemical employed as component B.
Generally for plant propagation material, such as seed treatment, application rates can vary from 0.001 to 10 g/kg of seeds of active ingredients. When the combinations of the present invention are used for treating seed, rates of 0.001 to 5 g of a compound of formula I per kg of seed, preferably from 0.01 to 1 g per kg of seed, and 0.001 to 5 g of a compound of component B, per kg of seed, preferably from 0.01 to 1 g per kg of seed, are generally sufficient.
The weight ratio of A to B may generally be between 1000:1 and 1:1000. In other embodiments that weight ratio of A to B may be between 500:1 to 1:500, for example between 100:1 to 1:100, for example between 1:50 to 50:1, for example 1:20 to 20:1. Other embodiments of weight ratios of component (B) to component (A) range from 500:1 to 1:250, with one embodiment being from 200:1 to 1:150, another embodiment being from 150:1 to 1:50 and another embodiment being from 50:1 to 1:10. Also of note are weight ratios of component (B) to component (A) which range from 450:1 to 1:300, with one embodiment being from 150:1 to 1:100, another embodiment being from 30:1 to 1:25 and another embodiment being from 10:1 to 1:10.
The invention also provides pesticidal mixtures comprising a combination of components A and B as mentioned above in a synergistically effective amount, together with an agriculturally acceptable carrier, and optionally a surfactant.
Spodoptera preferably means Spodoptera littoralis. Heliothis preferably means Heliothis virescens. Tetranychus preferably means Tetranychus urticae.
The compositions of the invention may be employed in any conventional form, for example in the form of a twin pack, a powder for dry seed treatment (DS), an emulsion for seed treatment (ES), a flowable concentrate for seed treatment (FS), a solution for seed treatment (LS), a water dispersible powder for seed treatment (WS), a capsule suspension for seed treatment (CF), a gel for seed treatment (GF), an emulsion concentrate (EC), a suspension concentrate (SC), a suspo-emulsion (SE), a capsule suspension (CS), a water dispersible granule (WG), an emulsifiable granule (EG), an emulsion, water in oil (EO), an emulsion, oil in water (EW), a micro-emulsion (ME), an oil dispersion (OD), an oil miscible flowable (OF), an oil miscible liquid (OL), a soluble concentrate (SL), an ultra-low volume suspension (SU), an ultra-low volume liquid (UL), a technical concentrate (TK), a dispersible concentrate (DC), a wettable powder (WP), a soluble granule (SG) or any technically feasible formulation in combination with agriculturally acceptable adjuvants.
Such compositions may be produced in conventional manner, e.g. by mixing the active ingredients with appropriate formulation inerts (diluents, solvents, fillers and optionally other formulating ingredients such as surfactants, biocides, anti-freeze, stickers, thickeners and compounds that provide adjuvancy effects). Also conventional slow release formulations may be employed where long lasting efficacy is intended. Particularly formulations to be applied in spraying forms, such as water dispersible concentrates (e.g. EC, SC, DC, OD, SE, EW, EO and the like), wettable powders and granules, may contain surfactants such as wetting and dispersing agents and other compounds that provide adjuvancy effects, e.g. the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, and ethoxylated alkylphenol and an ethoxylated fatty alcohol.
A seed dressing formulation is applied in a manner known per se to the seeds employing the combination of the invention and a diluent in suitable seed dressing formulation form, e.g. as an aqueous suspension or in a dry powder form having good adherence to the seeds. Such seed dressing formulations are known in the art. Seed dressing formulations may contain the single active ingredients or the combination of active ingredients in encapsulated form, e.g. as slow release capsules or microcapsules. A typical a tank-mix formulation for seed treatment application comprises 0.25 to 80%, especially 1 to 75%, of the desired ingredients, and 99.75 to 20%, especially 99 to 25%, of a solid or liquid auxiliaries (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 40%, especially 0.5 to 30%, based on the tank-mix formulation. A typical pre-mix formulation for seed treatment application comprises 0.5 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.5 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation.
In general, the formulations include from 0.01 to 90% by weight of active agent, from 0 to 20% agriculturally acceptable surfactant and 10 to 99.99% solid or liquid formulation inerts and adjuvant(s), the active agent consisting of at least the compound of formula I together with a compound of component B, and optionally other active agents, particularly microbiocides or conservatives or the like. Concentrated forms of compositions generally contain in between about 2 and 80%, preferably between about 5 and 70% by weight of active agent. Application forms of formulation may for example contain from 0.01 to 20% by weight, preferably from 0.01 to 5% by weight of active agent. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ diluted formulations.
A synergistic effect exists whenever the action of an active ingredient combination is greater than the sum of the actions of the individual components.
The action to be expected E for a given active ingredient combination obeys the so-called COLBY formula and can be calculated as follows (COLBY, S.R. “Calculating synergistic and antagonistic responses of herbicide combination”. Weeds, Vol. 15, pages 20-22; 1967):
ppm=milligrams of active ingredient (=a.i.) per liter of spray mixture
X=% action by active ingredient A) using p ppm of active ingredient
Y=% action by active ingredient B) using q ppm of active ingredient.
According to COLBY, the expected (additive) action of active ingredients A)+B) using p+q ppm of active ingredient is
If the action actually observed (O) is greater than the expected action (E), then the action of the combination is super-additive, i.e. there is a synergistic effect. In mathematical terms the synergism factor SF corresponds to O/E. In the agricultural practice an SF of ≧1.2 indicates significant improvement over the purely complementary addition of activities (expected activity), while an SF of ≦0.9 in the practical application routine signals a loss of activity compared to the expected activity.
Tables 1 to 123 show mixtures and compositions of the present invention demonstrating control on a wide range of invertebrate pests, some with notable synergistic effect. As the percent of mortality cannot exceed 100 percent, the unexpected increase in insecticidal activity can be greatest only when the separate active ingredient components alone are at application rates providing considerably less than 100 percent control. Synergy may not be evident at low application rates where the individual active ingredient components alone have little activity. However, in some instances high activity was observed for combinations wherein individual active ingredient alone at the same application rate had essentially no activity. The synergism is remarkable.
