The present invention relates to mixtures of pesticidally active ingredients and to methods of using the mixtures in the field of agriculture.
WO2010/020522 discloses that certain dihydropyrrole compounds have insecticidal activity.
The present invention provides pesticidal mixtures comprising a component A and a component B, wherein component A is a compound of formula I
wherein
one of Y1 and Y2 is S, SO or SO2 and the other is CH2;
L is a direct bond or methylene;
A1 and A2 are C—H, or one of A1 and A2 is C—H and the other is N;
R1 is hydrogen or methyl;
R2 is chlorodifluoromethyl or trifluoromethyl;
R3 is 3,5-dibromo-phenyl, 3,5-dichloro-phenyl, 3,4-dichloro-phenyl, or 3,4,5-trichloro-phenyl, 3-chloro-5-trifluoromethyl-phenyl, 3,5-dichloro-4-fluoro-phenyl, or 3,5-bis-trifluoromethylphenyl;
R4 is methyl or chlorine;
R5 is hydrogen;
or R4 and R5 together form a bridging 1,3-butadiene group;
and component B is a compound selected from
In addition, component B may be a nematicidally active biological agents. 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 WO2010/020522, GB 0910768.1 (to which WO2010/020522 claims priority) and PCT/EP2010/058207 The components B are known, e.g. from “The Pesticide Manual”, Fifteenth Edition, Edited by Clive Tomlin, British Crop Protection Council.
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.

For example, when component A is an enantiomerically enriched mixture of formula I**, the molar proportion of compound I** compared to the total amount of both enantiomers is for example greater than 50%, e.g. at least 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, or at least 99%. Likewise, when component A is an enantiomerically enriched mixture of formula I*, the molar proportion of the compound of formula I* compared to the total amount of both enantiomers is for example greater than 50%, e.g. at least 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, or at least 99%.

Insects, acarines, nematodes and molluscs are herein collectively referred to as pests. The pests which may be controlled by the use of the invention compounds include those pests associated with agriculture (which term includes the growing of crops for food and fiber products), horticulture and animal husbandry, companion animals, forestry and the storage of products of vegetable origin (such as fruit, grain and timber); those pests associated with the damage of man-made structures and the transmission of diseases of man and animals; and also nuisance pests (such as flies). 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®.
Plants are also to be understood as being those which by the use of recombinant DNA techniques are capable of producing one or more pesticidal proteins which confer upon the transgenic plant tolerance or resistance to harmful pests, e.g. insect pests, nematode pests and the like. Such pesticidal proteins include, without limitation, Cry proteins from Bacillus thuringiensis Cry1Ab, Cry1Ac, Cry1F, Cry2Ab, Cry2Ae, Cry3A, Cry3Bb, or Cry9C; engineered proteins such as modified Cry3A (U.S. Pat. No. 7,030,295) or Cry1A.105; or vegetative insecticidal proteins such as Vip1, Vip2 or Vip3. A full list of Bt Cry proteins and VIPs useful in the invention can be found on the worldwide web at Bacillus thuringiensis Toxin Nomenclature Database maintained by the University of Sussex (see also, Crickmore et al. (1998) Microbiol. Mol. Biol. Rev. 62:807-813). Other pesticidal proteins useful in the invention include proteins of bacteria colonizing nematodes, e.g. 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. Further examples of such pesticidal proteins or transgenic plants capable of synthesizing such proteins are disclosed, e.g., in EP-A 374753, WO 93/007278, WO 95/34656, EP-A 427529, EP-A 451878, WO 03/18810 and WO 03/52073. The methods for producing such transgenic plants are generally known to the person skilled in the art and some of which are commercially available such as Agrisure® CB (corn producing Cry1Ab), Agrisure® RW (corn producing mCry3A), Agrisure® Viptera (corn hybrids producing Vip3Aa); Agrisure300GT (corn hybrids producing Cry1Ab and mCry3A); YieldGard® (corn hybrids producing the Cry1Ab protein), YieldGard® Plus (corn hybrids producing Cry1Ab and Cry3Bb1), Genuity® SmartStax® (corn hybrids with Cry1A.105, Cry2Ab2, Cry1F, Cry34/35, Cry3Bb); Herculex® I (corn hybrids producing Cry1Fa) and Herculex® RW (corn hybrids producing Cry34Ab1, Cry35Ab1 and the enzyme Phosphinothricin-N-Acetyltransferase [PAT]); NuCOTN®33B (cotton cultivars producing Cry1Ac), Bollgard® I (cotton cultivars producing Cry1Ac), Bollgard® II (cotton cultivars producing Cry1Ac and Cry2Ab2) and VIPCOT® (cotton cultivars producing a Vip3Aa).
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 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.

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, for example 1:10 to 10:1, for example 1:5 to 5:1. Other examples of weight ratios of A to B include 1:1, 1:2, 1:3, 1:4, 2:1, 3:1, 4:1.
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 invention also relates to the following three-way combinations described in the tables below, which may act synergistically. Synergism may also arise from combination of compounds of formula I with B and C separately. Combinations with fungicides can result in synergistic fungal control.

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.
Spodoptera littoralis (Egyptian Cotton Leaf Worm)
Cotton leaf discs are placed on agar in Petri dishes and sprayed with test solutions in an application chamber. After drying, the leaf discs are infested with 10 L1 larvae. The samples are checked for mortality 5 days after treatment.
Heliothis virescens (Tobacco Budworm):
30-35 fresh eggs (0-24 h old), deposited on filter paper, are placed in Petri dishes on top of a layer of artificial diet and 0.8 ml of diluted test solutions are pipetted onto them. After an incubation period of 7 days, samples are checked for egg and larval mortality.
Heliothis virescens (Tobacco budworm)
Eggs (0-24 h old) are placed in 24-well microtiter plate on artificial diet and treated with test solutions (DMSO) by pipetting. After an incubation period of 4 days, samples are checked for larval mortality.
Tetranychus urticae (Two Spotted Spider Mite)
Bean plants are infested with mite populations of mixed ages. 1 day after infestation, plants are treated in a spray chamber with diluted test solutions. 1 and 8 days later, samples are checked for adult mortality. 2 replicates per treatment were evaluated.
Tetranvchus urticae (Two-Spotted Spider Mite)
Bean leaf discs on agar in 24-well microtiter plates are sprayed with test solutions (DMSO). After drying, the leaf discs are infested with mite populations of mixed ages. 8 days later, discs are checked for mixed population mortality.
The skilled person will understand that a variety of organisms and test methods (in vivo or in vitro) can be used to demonstrate synergy.
