Patent Application
20200397001
The invention relates to a method for controlling pests of soybean plants, comprising the step of contacting the plant, parts of it, its propagation material, the pests, their food supply, habitat or breeding grounds with one or more compounds of formula I
wherein,
The above compounds can be used in pure form or as mixtures.
These compounds therefore represent an important solution for controlling pests of Faboideae, in particular soybeans, in particular pests from the family of pentatomidae, stink bugs, and thereby safeguarding plants, crops and propagation material from the infestation by such pests, particularly where the pests are resistant to current methods.
The compounds of formula I can be prepared by methods disclosed in the patent publication WO2016171053.
The organic moieties mentioned in the definition of the variables Ra, R1, R2, R3, R4 and R5, are—like the term halogen—collective terms for individual enumerations of the individual group members. The term halogen denotes in each case F, Cl, Br, or I. All hydrocarbon chains, e.g. all alkyl, alkenyl, alkynyl, alkoxy chains can be straight-chain or branched, the prefix Cn-Cm denoting in each case the possible number of carbon atoms in the group.
Examples of such meanings are:
The term “substituted” or “substituted with one or more” if not specified otherwise refers to substituted with 1, 2, or up to maximum possible number of substituents. If substituents as defined in compounds of formula I are more than one then they are independently from each other are same or different if not mentioned otherwise.
Faboideae, such as soybeans (Glycine max), are important commercial crops.
Soybeans are considered to be a source of complete protein (Henkel, J., 2000, “Soy: Health Claims for Soy Protein, Question About Other Components”. FDA Consumer (Food and Drug Administration 34 (3): 18-20). For this reason, soy is a good source of protein. According to the US Food and Drug Administration, soy protein products can be good substitutes for animal products because soy offers a ‘complete’ protein profile. Soy protein products can replace animal-based foods which also have complete proteins but tend to contain more fat, especially saturated fat without requiring major adjustments elsewhere in the diet.
Soybean protein isolate is highly valuable as it has a biological value of 74 (Protein Quality Evaluation: Report of the Joint FAO/WHO Expert Consultation. Bethesda, Md. (USA): Food and Agriculture Organization of the United Nations (Food and Nutrition Paper No. 51, December 1989).
In agriculture soybeans can produce at least twice as much protein per acre than some other major vegetable or grain crop, e.g. 5 to 10 times more protein per acre than land set aside for grazing animals to make milk, and up to 15 times more protein per acre than land set aside for meat production (“Soy Benefits”, National Soybean Research Laboratory, February 2012).
Thus, soybeans can be regarded as a globally important crop providing oil and protein.
Nevertheless, soybean plants are vulnerable to a wide range of bacterial diseases, fungal diseases, viral diseases and parasites. Soybeans are considered to be e.g. the second-most valuable agricultural export in the United States behind corn.
Consequently, in view of the importance of soybean in agriculture, proper pest management is required in order not to jeopardize yield and quality of the soybean crops.
Stink bugs (order of Hemiptera, family of Pentatomidae) are animal pests and true bugs. They are probably one of the most common pest problems in soybean (Stewart et al., Soybean Insects—Stink bugs, University of Tennessee Institute of Agriculture, W200 09-0098).
Stink bugs feed on over 52 plants, including native and ornamental trees, shrubs, vines, weeds, and many cultivated crops such as corn and cotton, as well as numerous uncultivated plants, and their preferred hosts are nearly all wild plants. They build up on these hosts and move to soybeans late in the season as their preferred foods mature.
Stink bugs may feed on many parts of the plant; however, they typically target developing seed including the pods, meaning that injury to soybean seed is the primary problem associated with stink bug infestations.
Brown or blackish spots may occur where their mouthparts penetrate the plant tissue, but little external signs of feeding injury may be present. Feeding may cause deformation, shriveling or abortion of small seed. Larger seed may only be partly discolored by feeding injury, but this can affect seed quality. High levels of seed abortion may cause the “green bean effect” where foliage is retained and plant maturity is delayed (Stewart et al., Soybean Insects—Stink bugs, University of Tennessee Institute of Agriculture, W200 09-0098).
Stink bugs inflict mechanical injury to the seed as well as transmitting the yeast-spot disease organism. The degree of damage caused by this pest depends to some extent on the developmental stage of the seed when it is pierced by the stink bug's needlelike mouthparts. The younger the seed when damaged, the greater the yield reduction. Although late season infestations may not affect yield, bean oil content and germination will be reduced.
In certain regions, the green stink bug (Acrosternum hilare) is one of the most common species that feeds on soybean. The brown stink bug (Euschistus servus) is another common component of the stink bug complex.
Of the complex of sucking bugs that occur in cultivation, the brown stinkbug Euschistus heros is currently considered to be the most abundant species in northern Parana to Central Brazil (Correa-Ferreira & Panizzi, 1999), and is a significant problem in soybean (Schmidt et al., 2003). The bugs occur in soybeans from the vegetative stage and are harmful from the beginning of pod formation until grain maturity. They cause damage to the seed (Galileo & Heinrichs 1978, Panizzi & Slansky Jr., 15, 1985) and can also open the way to fungal diseases and cause physiological disorders, such as soybean leaf retention (Galileo & Heinrichs 1978, Todd & Herzog, 1980).
Other plant feeding species that may be present include the red-shouldered stink bug (Thyanta custator) and the dusky-brown stink bug (Euschistus tristigmus). Another species, the southern green stink bug (Nezara viridula), is often confined to the southernmost counties of the US. Predatory (beneficial) stink bugs such as the spined soldier bug (Podisus maculaventris) may also be found in soybean and are sometimes mistaken for brown or dusky-brown stink bugs.
Control of stinkbugs in soybean is often vital to prevent significant economic damage.
Insecticides commonly used to control stinkbugs include pyrethroids, neonicotinoids and organophosphates, though pyrethroid insecticides are usually the method of choice for controlling stink bugs in soybean. However, there are increasing problems with insecticide resistance, particularly in brown stink bug populations and particularly to pyrethroids. Euschistus heros can also be difficult to manage using organophosphates or endosulfan (Sosa-Gomez et al., 2009). There is therefore a need for effective ecological methods of controlling stinkbugs in soybean.
It has now been found that compounds of formula I provide an efficient control against pests on Faboideae, in particular soybeans, more particularly genetically modified soybeans, especially against pests from the family of Pentatomidae, family of Agromyzidae, family of Sternorrhyncha, order of Lepidoptera, and/or order of Thysanoptera, particularly against pests from the families of Pentatomidae, Noctuidae, Pyralidae, Agromyzidae, and Thripidae.
These compounds therefore represent an important solution for controlling pests of Faboideae, in particular soybeans, more particularly genetically modified soybeans, in particular pests from the family of Pentatomidae, stink bugs, and thereby safeguarding plants, crops and propagation material from the infestation by such pests, particularly where the pests are resistant to current methods.
Compounds of formula I and their pesticidal activities are disclosed in WO2016171053.
None of these documents disclose an acceptable efficacy of compounds of formula I against typical pests of Faboideae, preferably soybeans, more preferably genetically modified soybeans, in particular against stink bugs.

Preferably application is to a crop of Faboideae, such as soybean or the locus thereof, more preferably to a crop of soybean plants. Application may be before infestation or when the pest is present. Application of the compounds of the invention can be performed according to any of the usual modes of application, e.g. foliar, drench, soil, in furrow etc. Control of stinkbugs can be achieved by foliar application, which is a preferred mode of application according to the invention.
In another preferred embodiment, the compounds of the invention are applied to Faboideae crops by soil-drench application. In one preferred embodiment, the Faboideae crops are soybean crops.
In a further preferred embodiment the compounds of the invention are applied as seed-treatment to seeds of Faboideae, and Bt Faboideae crops. In one preferred embodiment, the Faboideae crops are soybean crops, particularly Bt soybean crops.
The pest, e.g. the stink bugs, the plant, soil or water in which the plant is growing can be contacted with the compounds of the invention or composition(s) containing them by any further application method known in the art. As such, “contacting” includes both direct contact (applying the compounds/compositions directly on the animal pest or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the animal pest or plant).
The compounds of the invention or the pesticidal compositions comprising them may be used to protect growing plants and crops from attack or infestation by animal pests, especially from stink bugs, in particular from Euschistus, more particularly from E. heros, by contacting the plant/crop with a pesticidally effective amount of compounds of the invention. The term “crop” refers both to growing and harvested crops.
The compounds of the invention may be applied in combination with an attractant. An attractant is a chemical that causes the insect to migrate towards the location of application. For control of stinkbugs it can be advantageous to apply the compounds of the invention with an attractant, particularly when the application is foliar. Stinkbugs are often located near to the ground, and application of an attractant may encourage migration up the plant towards the active ingredient.
Suitable attractants include glucose, sacchrose, salt, glutamate, citric acid, soybean oil, peanut oil and soybean milk. Glutamate and citric acid are of particular interest, with citric acid being preferred.
An attractant may be premixed with the compound of the invention prior to application, e.g. as a readymix or tankmix, or by simultaneous application or sequential application to the plant. Suitable rates of attractants are for example 0.02 kg/ha-3 kg/ha.
The compounds of the invention are preferably used for pest control on Faboideae, in particular soybean, at 1-500 g/ha, preferably 10-100 g/ha.
The compounds of the invention are suitable for use on any Faboideae plant, such as soybean plants, including those that have been genetically modified to be resistant to active ingredients such as herbicides or to produce biologically active compounds that control infestation by plant pests.
In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof, are treated. Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are understood as meaning plants having novel properties (“traits”) which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques.
These can be cultivars, bio- or genotypes. Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive “synergistic”) effects.
Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible, which exceed the effects which were actually to be expected.
The preferred transgenic plants or plant cultivars (obtained by genetic engineering) which are to be treated according to the invention include all plants which, by virtue of the genetic modification, received genetic material which imparts particularly advantageous, useful traits to these plants.
Examples of such traits are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products.
Further and particularly emphasized examples of such traits are a better defense of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds.
Traits that are emphasized in particular are the increased defense of the plants against insects, arachnids, nematodes and slugs and snails by virtue of toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes Cry1A, Cry1Ab, Cry1Ab(truncated), Cry1Ab-Ac, Cry1Ac, Cry1A.105, Cry1C, Cry2A, Cry3A, Cry3B2, Cry9c, Cry2Ab, Cry2Ab2, Cry3Bb, Cry3Bb1, Cry34Ab1, Cry35Ab1, Cry3A, mCry3A and Cry1F, Cry1Fa2, dvsnf7, moCry1F, pinII, vip3Aa and vip3Aa20 and also combinations thereof) (referred to herein as “Bt plants”). Traits that are also particularly emphasized are the increased defense of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins.
Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants.
Examples of “Bt plants” are soybean varieties which are sold under the trade names YIELD GARD®, Intacta®, Intacta®2, Intacta® Roundup Ready™ 2 Pro (Intacta®RR2 PRO), Cultivance, Conkesta Soybean, Conkesta Enlist E3™ Soybean, Enlist™ Soybean, Enlist E3™ Soybean, Roundup Ready™ Soybean, Genuity® Roundup Ready™ 2 Xtend™, Genuity® Roundup Ready 2 Yield™, Herbicide-tolerant Soybean line, Optimum GAT™, Liberty Link™ Soybean, Vistive Gold™, Verdeca HB4 Soybean, Treus™, Plenish™.
Examples of herbicide-tolerant plants which may be mentioned are soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate), Liberty Link® (tolerance to phosphinotricin), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas). An example of a glyphosate tolerant soybean cultivar is BMX Potência.
Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize).
In another preferred embodiment, the compounds of the invention are applied to Faboideae, in particular soybean plants, carrying two or more traits (e.g. Enlist®), glyphosate (e.g. Roundup Ready®, Roundup Ready 2 Yield®), sulfonylurea (e.g. STS®), glufosinate (e.g. Liberty Link®, Ignite®), Dicamba (Monsanto) HPPD tolerance (e.g. isoxaflutole herbicide) (Bayer Crop-Science, Syngenta). Double or triple stack in soybean plants of any of the traits described here are also of interest, including glyphosate and sulfonyl-urea tolerance (e.g. Optimum GAT®, plants stacked with STS® and Roundup Ready® or Roundup Ready 2 Yield®), dicamba and glyphosate tolerance (Monsanto). Soybean Cyst Nematode resistance soybean (SCN®—Syngenta) and soybean with Aphid resistant trait (AMT®—Syngneta) are also of interest.
These statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plant cultivars will be developed and/or marketed in the future.

The agrochemical compositions generally comprise between 0.01 and 95%, preferably between 0.1 and 90%, and most preferably between 0.5 and 75%, by weight of active substance. The active substances are employed in a purity of from 90% to 100%, preferably from 95% to 100% (according to NMR spectrum).
Various types of oils, wetters, adjuvants, fertilizer, or micronutrients, and other pesticides (e.g. herbicides, insecticides, fungicides, growth regulators, safeners) may be added to the active substances or the compositions comprising them as premix or, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the compositions according to the invention in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.
The user applies the composition according to the invention usually from a predosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. Usually, the agrochemical composition is made up with water, buffer, and/or further auxiliaries to the desired application concentration and the ready-to-use spray liquor or the agrochemical composition according to the invention is thus obtained. Usually, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to-use spray liquor are applied per hectare of agricultural useful area.
According to one embodiment, individual components of the composition according to the invention such as parts of a kit or parts of a binary or ternary mixture may be mixed by the user himself in a spray tank and further auxiliaries may be added, if appropriate.
In a further embodiment, either individual components of the composition according to the invention or partially premixed components, e. g. components comprising compounds of the present invention and/or mixing partners as defined above, may be mixed by the user in a spray tank and further auxiliaries and additives may be added, if appropriate.
In a further embodiment, either individual components of the composition according to the invention or partially premixed components, e. g. components comprising compounds of the present invention and/or mixing partners as defined above, can be applied jointly (e.g. after tank mix) or consecutively.
The compounds of the present invention are suitable for use in protecting crops, plants, plant propagation materials, such as seeds, or soil or water, in which the plants are growing, from attack or infestation by animal pests. Therefore, the present invention also relates to a plant protection method, which comprises contacting crops, plants, plant propagation materials, such as seeds, or soil or water, in which the plants are growing, to be protected from attack or infestation by animal pests, with a pesticidally effective amount of a compound of the present invention.
The compounds of the present invention are also suitable for use in combating or controlling animal pests. Therefore, the present invention also relates to a method of combating or controlling animal pests, which comprises contacting the animal pests, their habitat, breeding ground, or food supply, or the crops, plants, plant propagation materials, such as seeds, or soil, or the area, material or environment in which the animal pests are growing or may grow, with a pesticidally effective amount of a compound of the present invention.
The compounds of the present invention are effective through both contact and ingestion. Furthermore, the compounds of the present invention can be applied to any and all developmental stages, such as egg, larva, pupa, and adult.
The compounds of the present invention can be applied as such or in form of compositions comprising them as defined above. Furthermore, the compounds of the present invention can be applied together with a mixing partner as defined above or in form of compositions comprising said mixtures as defined above. The components of said mixture can be applied simultaneously, jointly or separately, or in succession, that is immediately one after another and thereby creating the mixture “in situ” on the desired location, e.g. the plant, the sequence, in the case of separate application, generally not having any effect on the result of the control measures.
The application can be carried out both before and after the infestation of the crops, plants, plant propagation materials, such as seeds, soil, or the area, material or environment by the pests.
Suitable application methods include inter alia soil treatment, seed treatment, in furrow application, and foliar application. Soil treatment methods include drenching the soil, drip irrigation (drip application onto the soil), dipping roots, tubers or bulbs, or soil injection. Seed treatment techniques include seed dressing, seed coating, seed dusting, seed soaking, and seed pelleting. In furrow applications typically include the steps of making a furrow in cultivated land, seeding the furrow with seeds, applying the pesticidally active compound to the furrow, and closing the furrow. Foliar application refers to the application of the pesticidally active compound to plant foliage, e.g. through spray equipment. For foliar applications, it can be advantageous to modify the behavior of the pests by use of pheromones in combination with the compounds of the present invention. Suitable pheromones for specific crops and pests are known to a skilled person and publicly available from databases of pheromones and semiochemicals, such as http://www.pherobase.com.
As used herein, the term “contacting” includes both direct contact (applying the compounds or compositions directly on the animal pest or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus, i.e. habitat, breeding ground, plant, seed, soil, area, material or environment in which a pest is growing or may grow, of the animal pest or plant).
The term “crop” refers to both, growing and harvested crops.
The term “plant” includes cereals, e.g. durum and other wheat, rye, barley, triticale, oats, rice, or maize (fodder maize and sugar maize/sweet and field corn); beet, e.g. sugar beet or fodder beet; fruits, such as pomes, stone fruits or soft fruits, e.g. apples, pears, plums, peaches, nectarines, almonds, cherries, papayas, strawberries, raspberries, blackberries or gooseberries; leguminous plants, such as beans, lentils, peas, alfalfa or soybeans; oil plants, such as rapeseed (oilseed rape), turnip rape, mustard, olives, sunflowers, coconut, cocoa beans, castor oil plants, oil palms, ground nuts or soybeans; cucurbits, such as squashes, pumpkins, cucumber or melons; fiber plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruits or mandarins; vegetables, such as eggplant, spinach, lettuce (e.g. iceberg lettuce), chicory, cabbage, asparagus, cabbages, carrots, onions, garlic, leeks, tomatoes, potatoes, cucurbits or sweet peppers; lauraceous plants, such as avocados, cinnamon or camphor; energy and raw material plants, such as corn, soybean, rapeseed, sugar cane or oil palm; tobacco; nuts, e.g. walnuts; pistachios; coffee; tea; bananas; vines (table grapes and grape juice grape vines); hop; sweet leaf (also called Stevia); natural rubber plants or ornamental and forestry plants, such as flowers (e.g. carnation, petunias, geranium/pelargoniums, pansies and impatiens), shrubs, broad-leaved trees (e.g. poplar) or evergreens, e.g. conifers; eucalyptus; turf; lawn; grass such as grass for animal feed or ornamental uses. Preferred plants include potatoes sugar beets, tobacco, wheat, rye, barley, oats, rice, corn, cotton, soybeans, rapeseed, legumes, sunflowers, coffee or sugar cane; fruits; vines; ornamentals; or vegetables, such as cucumbers, tomatoes, beans or squashes.
The term “plant” is to be understood as including plants, which have been modified by either conventional breeding, or mutagenesis or genetic engineering, or by a combination thereof.
Plants, which have been modified by mutagenesis or genetic engineering, and are of particular commercial importance, include alfalfa, rapeseed (e.g. oilseed rape), bean, carnation, chicory, cotton, eggplant, eucalyptus, flax, lentil, maize, melon, papaya, petunia, plum, poplar, potato, rice, soybean, squash, sugar beet, sugarcane, sunflower, sweet pepper, tobacco, tomato, and cereals (e.g. wheat), in particular soybean. In plants, which have been modified by mutagenesis or genetic engineering, one or more genes have been mutagenized or integrated into the genetic material of the plant. The one or more mutagenized or integrated genes are preferably selected from pat, epsps, Cry1A, Cry1Ab, Cry1Ab(truncated), Cry1Ab-Ac, Cry1Ac, Cry1A.105, Cry1C, Cry2A, Cry3A, Cry3B2, Cry9c, Cry2Ab, Cry2Ab2, Cry3Bb, Cry3Bb1, Cry34Ab1, Cry35Ab1, Cry3A, mCry3A and Cry1F, Cry1Fa2, dvsnf7, moCry1F, pinII, vip3Aa and vip3Aa20, dfr, barnase, barstar, als, bxn, bp40, asn1, and ppo5. The mutagenesis or integration of the one or more genes is performed in order to improve certain properties of the plant. Such properties, also known as traits, include abiotic stress tolerance, altered growth/yield, disease resistance, herbicide tolerance, insect resistance, modified product quality, and pollination control. Of these properties, herbicide tolerance, e.g. imidazolinone tolerance, glyphosate tolerance, or glufosinate tolerance, is of particular importance. Several plants have been rendered tolerant to herbicides by mutagenesis, for example Clearfield® oilseed rape being tolerant to imidazolinones, e.g. imazamox. Alternatively, genetic engineering methods have been used to render plants, such as soybean, cotton, corn, beets and oil seed rape, tolerant to herbicides, such as glyphosate and glufosinate, some of which are commercially available under the trade names RoundupReady® (glyphosate) and LibertyLink® (glufosinate). Furthermore, insect resistance is of importance, in particular lepidopteran insect resistance. Insect resistance is typically achieved by modifying plants by integrating cry and/or vip genes, which were isolated from Bacillus thuringiensis (Bt), and code for the respective Bt toxins. Genetically modified plants with insect resistance are commercially available under trade names including WideStrike®, Bollgard®, Agrisure®, Herculex®, YieldGard®, Genuity®, Intacta®, Intacta®2, and Intacta® RR2 PRO. Plants may be modified by mutagenesis or genetic engineering either in terms of one property (singular traits) or in terms of a combination of properties (stacked traits). Stacked traits, e.g. the combination of herbicide tolerance and insect resistance, are of increasing importance. In general, all relevant modified plants in connection with singular or stacked traits as well as detailed information as to the mutagenized or integrated genes and the respective events are available from websites of the organizations “International Service for the Acquisition of Agri-biotech Applications (ISAAA)” (http://www.isaaa.org/gmapprovaldatabase) and “Center for Environmental Risk Assessment (CERA)” (http://cera-gmc.org/GMCropDatabase).
It has surprisingly been found that the pesticidal activity of the compounds of the invention may be enhanced by the insecticidal trait of a modified plant. Furthermore, it has been found that the compounds of the present invention are suitable for preventing insects to become resistant to the insecticidal trait or for combating pests, which already have become resistant to the insecticidal trait of a modified plant. Moreover, the compounds of the present invention are suitable for combating pests, against which the insecticidal trait is not effective, so that a complementary insecticidal activity can advantageously be used.
The term “plant propagation material” refers to 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 included. These plant propagation materials may be treated prophylactically with a plant protection compound either at or before planting or transplanting.
The term “seed” embraces seeds and plant propagules of all kinds including but not limited to true seeds, seed pieces, suckers, corms, bulbs, fruit, tubers, grains, cuttings, cut shoots and the like, and means in a preferred embodiment true seeds.
In general, “pesticidally effective amount” means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various compounds/compositions used in the invention. A pesticidally effective amount of the compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.
In the case of soil treatment, in furrow application or of application to the pests dwelling place or nest, the quantity of active ingredient ranges from 0.0001 to 500 g per 100 m2, preferably from 0.001 to 20 g per 100 m2.
For use in treating crop plants, e.g. by foliar application, the rate of application of the active ingredients of this invention may be in the range of 0.0001 g to 4000 g per hectare, e.g. from 1 g to 2 kg per hectare or from 1 g to 750 g per hectare, desirably from 1 g to 100 g per hectare, more desirably from 10 g to 50 g per hectare, e.g., 10 to 20 g per hectare, 20 to 30 g per hectare, 30 to 40 g per hectare, or 40 to 50 g per hectare.
The compounds of the present invention are particularly suitable for use in the treatment of seeds in order to protect the seeds from insect pests, in particular from soil-living insect pests, and the resulting seedling's roots and shoots against soil pests and foliar insects. The present invention therefore also relates to a method for the protection of seeds from insects, in particular from soil insects, and of the seedling's roots and shoots from insects, in particular from soil and foliar insects, said method comprising treating the seeds before sowing and/or after pregermination with a compound of the present invention. The protection of the seedling's roots and shoots is preferred. More preferred is the protection of seedling's shoots from piercing and sucking insects, chewing insects and nematodes.
The term “seed treatment” comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking, seed pelleting, and in-furrow application methods. Preferably, the seed treatment application of the active compound is carried out by spraying or by dusting the seeds before sowing of the plants and before emergence of the plants.
The present invention also comprises seeds coated with or containing the active compound. The term “coated with and/or containing” generally signifies that the active ingredient is for the most part on the surface of the propagation product at the time of application, although a greater or lesser part of the ingredient may penetrate into the propagation product, depending on the method of application. When the said propagation product is (re)planted, it may absorb the active ingredient.
Suitable seed is for example seed of cereals, root crops, oil crops, vegetables, spices, ornamentals, for example seed of durum and other wheat, barley, oats, rye, maize (fodder maize and sugar maize/sweet and field corn), soybeans, oil crops, crucifers, cotton, sunflowers, bananas, rice, oilseed rape, turnip rape, sugarbeet, fodder beet, eggplants, potatoes, grass, lawn, turf, fodder grass, tomatoes, leeks, pumpkin/squash, cabbage, iceberg lettuce, pepper, cucumbers, melons, Brassica species, melons, beans, peas, garlic, onions, carrots, tuberous plants such as potatoes, sugar cane, tobacco, grapes, petunias, geranium/pelargoniums, pansies and impatiens.
In addition, the active compound may also be used for the treatment of seeds from plants, which have been modified by mutagenesis or genetic engineering, and which e.g. tolerate the action of herbicides or fungicides or insecticides. Such modified plants have been described in detail above.
Conventional seed treatment formulations include for example flowable concentrates FS, solutions LS, suspoemulsions (SE), powders for dry treatment DS, water dispersible powders for slurry treatment WS, water-soluble powders SS and emulsion ES and EC and gel formulation GF. These formulations can be applied to the seed diluted or undiluted. Application to the seeds is carried out before sowing, either directly on the seeds or after having pregerminated the latter. Preferably, the formulations are applied such that germination is not included.
The active substance concentrations in ready-to-use formulations, which may be obtained after two-to-tenfold dilution, are preferably from 0.01 to 60% by weight, more preferably from 0.1 to 40% by weight.
In a preferred embodiment a FS formulation is used for seed treatment. Typically, a FS formulation may comprise 1-800 g/l of active ingredient, 1-200 g/l Surfactant, 0 to 200 g/l anti-freezing agent, 0 to 400 g/l of binder, 0 to 200 g/l of a pigment and up to 1 liter of a solvent, preferably water.
Especially preferred FS formulations of the compounds of the present invention for seed treatment usually comprise from 0.1 to 80% by weight (1 to 800 g/l) of the active ingredient, from 0.1 to 20% by weight (1 to 200 g/l) of at least one surfactant, e.g. 0.05 to 5% by weight of a wetter and from 0.5 to 15% by weight of a dispersing agent, up to 20% by weight, e.g. from 5 to 20% of an anti-freeze agent, from 0 to 15% by weight, e.g. 1 to 15% by weight of a pigment and/or a dye, from 0 to 40% by weight, e.g. 1 to 40% by weight of a binder (sticker/adhesion agent), optionally up to 5% by weight, e.g. from 0.1 to 5% by weight of a thickener, optionally from 0.1 to 2% of an anti-foam agent, and optionally a preservative such as a biocide, antioxidant or the like, e.g. in an amount from 0.01 to 1% by weight and a filler/vehicle up to 100% by weight.
In the treatment of seed, the application rates of the compounds of the invention are generally from 0.1 g to 10 kg per 100 kg of seed, preferably from 1 g to 5 kg per 100 kg of seed, more preferably from 1 g to 1000 g per 100 kg of seed and in particular from 1 g to 200 g per 100 kg of seed, e.g. from 1 g to 100 g or from 5 g to 100 g per 100 kg of seed.
The invention therefore also relates to seed comprising a compound of the present invention, or an agriculturally useful salt thereof, as defined herein. The amount of the compound of the present invention or the agriculturally useful salt thereof will in general vary from 0.1 g to 10 kg per 100 kg of seed, preferably from 1 g to 5 kg per 100 kg of seed, in particular from 1 g to 1000 g per 100 kg of seed. For specific crops such as lettuce the rate can be higher.

Brown Stink Bug (Euschistus heros)
The active compound is dissolved at the desired concentration in a mixture of 1:1 (vol:vol) distilled water:acetone. Soybean seedlings of Intacta and BMX-Potencia with one pair of true leaves were sprayed 10 with 2 ml solution using an airbrush. After dry, the plants in small pots were placed inside a transparent plastic cage and infested with 10 adults adult stage individuals. Treated cups were kept at about 25° C. Percent mortality was recorded after 6 days after application. In this test, compounds C9 and C-8 at 100 ppm showed 70% and 68% mortality* * Corrected mortality according to Abbott, W. S., A method of computing the effectiveness of an insecticide, J. Econ. Entomal., 18 (1925) 265-267. The test shows that C9 and C8 have a higher efficacy when applied to soybean plants containing a toxin trait of Bacillus thuringiensis (INTACTA) than when applied to genetically modified soybean plants without the Bacillus thuringiensis trait (BMX-POTENCIA).
This is surprising since the values in the untreated groups (corrected according to Abbott) are equal, i.e. the Bacillus thuringiensis toxin alone does not control brown stink bugs.
Green Soldier Stink Bug (Nezara viridula)
Lima Bean (Phaseolus lunatus, ‘Henderson Bush,’ Lot #—VR06650) plants were transplanted at the two true-leaf stage into 25.8 cm2 pots filled with sifted (No. 10 sieve). Pots were held in the greenhouse and watered daily until treatment. Three days after transplant, the compounds were dissolved in acetone and then diluted with water for a final concentration of 50% acetone. Treatments were applied as a drench in 1 ml solution per plant. Plants were held in an environmental chamber (25±2° C., 24 L) and watered as needed for the duration of the test.
Three days after treatment, plants were infested with five 2nd instar nymphs. Plants were 15 covered with organza fabric bags to prevent escape. Four days after infestation, the number of live nymphs on each plant was recorded, and means were calculated for each treatment. The percent control was calculated as the percent mortality relative to the solvent blank.
In this test, C8 at 250 g ai/ha showed at least 75% mortality in comparison with untreated controls.
