Description

PESTICIDAL BAIT COMPOSITIONS AND PROCESSES RELATED THERETOBACKGROUND

[0001] Disclosed herein are bait compositions comprising pesticidally-active thiazolidine compounds. Such pesticidally-active thiazolidine compounds are disclosed in WO 2021 / 011722 A1

[0002] The compositions disclosed herein are related to bait formulations specifically designed for the delivery of the thiazoldine compounds. The compositions are designed to effectively control, combat, prevent and / or eradicate pests or pest populations. The compositions disclosed herein are particularly suitable for use in agricultural, residential and commercial settings. In one aspect, the compositions comprise the thiazolidine compound disclosed herein embedded in a pest-attractant matrix, which ensures the targeted delivery / ingestion of the active and subsequent mortality.

[0003] A bait formulation is particularly well-suited against chewing pests compared to sucking pests due to the distinct feeding behaviors of these two groups. Chewing pests actively consume solid plant material for example, making them more likely to ingest the bait directly. This ensures that the active ingredient is effectively delivered to the pest, resulting in rapid and efficient control. In contrast, sucking pests, such as aphids and whiteflies, feed on plant sap through piercing-sucking mouthparts and are less likely to consume solid bait formulations. Consequently, bait formulations are a highly efficient, user-friendly, and environmentally conscious solution for managing chewing pest populations in agricultural, residential, and commercial settings.SUMMARY

[0004] Disclosed herein are bait compositions comprising A) a compound of Formula One (I) or a compound of Formula Two (II), B) a carrier and C) a pest attractant. In some aspects, the pest attractant is a pest food attractant. In some other aspects, the pest attractant is a phagostimulant. In some other aspects, the pest attractant is a pheromone that attracts the pests. In some aspects, disclosed herein is a bait composition comprising A) compound of FormulaOne (I), B) a carrier, and C) a pest attractant. In some other aspects, disclosed herein is a bait composition comprising A) compound of Formula One (I) or Formula Two (II) and B) a carrier wherein the carrier also serves as a pest attractant. In other words, the carrier can be a pest attractant such as a food attractant or a phagostimulant. For example, compound of Formula One(I) or compound of Formula Two (II) is embedded in a solid matrix and that solid matrix can serve as a pest attractant. In such instances, a separate pest attractant is not necessary.DECRIPTION OF FIGURES

[0006] Disclosed herein are bait compositions comprising either a compound of Formula One (I) or a compound of Formula Two (II) embedded in a pest attractant matrix.Compound of Formula Two (II)

[0007] Compounds of Formula I and Formula II are prepared according to the processes disclosed in WO 2021 / 011722 Al.

[0008] In some instances, the matrix can be solid or a liquid. In some other instances, the matrix comprises compounds of Formula I or Formula II, a carrier material and a pest attractant. In some instances, the matrix comprises a carrier material that also acts as a pest attractant. In some instances, the matrix itself can act as a carrier material. The carrier material or the matrix can be a pest attractant while in some instances, the carrier material or the matrix may comprise one or more pest attractants. The carrier material can be a solid or a liquid as suitable for a specific application or the formulation type.

[0009] The phrase “pesticidally effective amount” means the amount of a pesticide needed to achieve an observable effect on a pest, for example, the effects of necrosis, death, retardation, prevention, removal, destruction, or otherwise diminishing the occurrence and / or activity of a pest in a locus. This effect may come about when pest populations are repulsed from a locus, pests are incapacitated in or around a locus, and / or pests are exterminated in or around a locus. In some instances, a combination of these effects can occur. Generally, pest populations, activity, or both are desirably reduced more than fifty percent, preferably more than 90 percent, and most preferably more than 99 percent. In general, a pesticidally effective amount, for agricultural purposes, is from about 0.0001 grams per hectare to about 5000 grams per hectare, preferably from about 0.0001 grams per hectare to about 500 grams per hectare, and it is even more preferably from about 0.0001 grams per hectare to about 50 grams per hectare.

[0010] The term “locus” means a habitat, breeding ground, plant, seed, soil, material, or environment, in which a pest is growing, may grow, or may traverse. For example, a locus may be where crops, trees, fruits, cereals, fodder species, vines, turf, and / or ornamental plants, are growing; where domesticated animals are residing; the interior or exterior surfaces of buildings (such as places where grains are stored); residences, camps, hotels, schools, public transportations such as trains, buses, ships and like where a pest may inhabit, grow or traverse, the materials of construction used in buildings (such as impregnated wood); and the soil around buildings. For example, pests such as termites and cockroaches may be found in residential structures, buildings and or facilities.

[0011] The term “pest” means an organism that is detrimental to humans, or human concerns (such as, crops, food, livestock, etc.), where said organism is from Phyla Arthropoda, Mollusca,or Nematoda. Particular examples are ants, aphids, bed bugs, beetles, borers, bristletails, butterflies, caterpillars, cockroaches, crickets, earwigs, fleas, flies, grasshoppers, grubs, hornets, jassids, leafhoppers, lice, locusts, maggots, mealybugs, mites, moths, mosquitos, nematodes, plantbugs, planthoppers, psyllids, sawflies, scales, silverfish, slugs, snails, spiders, springtails, stink bugs, symphylans, termites, thrips, ticks, wasps, whiteflies, fruit flies and wireworms.

[0012] In one aspect, disclosed herein are bait compositions that can be used to control, eliminate, combat, prevent infestation of pests that are harmful to humans, animals, crops, dwellings, storage facilities, and the like.

[0013] The compositions disclosed herein comprise a substance or an agent, that attracts the pests. In particular, the disclosure herein relates to bait compositions for controlling or combating pests. In some aspect, the pest is an insect pest. In another aspect, the disclosure herein relates to use of the insecticidal bait compositions. In one another aspect, the disclosure herein relates to method of preparation of such bait compositions. In another aspect, the disclosure herein relates to methods of controlling or combating insect pests using disclosed bait compositions.

[0014] In some aspects, food attractants are used as the bait material. These food attractants, in some instances, can be a food source for an insect. In other cases, while not being a food source per se, they can act as a material that can attract the insects to the bait composition over a distance, or when the insect is in the locus or vicinity of the bait composition.

[0015] In some instances, the food attractant is a phagostimulant (food flavorant). These are materials that stimulate insect feeding of the insecticide bait composition once the composition is encountered by the target insect. In some instances, mixtures of a food flavorant and food attractant can be used. In some instances, a food attractant can also function as a food flavorant.

[0016] Suitable food attractants can be selected from the group consisting of a grain, a protein, a vegetable, a lipid, a fruit, a plant extract, a plant-based oil such as a vegetable oil or a seed oil, animal byproducts such as animal-based oil and fish meal a carbohydrate, sugars and cellulose materials and mixtures thereof.

[0022] Examples of specific food attractants or flavorants are citrus pulp, soybean oil, methylamine, dimethylamine, trimethylamine, ethylmethylamine, propylmethylamine, isopropylamine, tert-butylamine, 1-methylpyrrolidine, di ethylamine, dimethylacetamide, furfuryl alcohol, 5-methyl-3-heptanone, geranyl butyrate, linalool, 1,3 -di ethylbenzene, 2-nonanone, (E)-2-hexanoic acid, ammonium acetate, ammonium phosphate,ammonia solution from 10 percent to 30 percent in water, putrescine, cadaverine, trimedlure, a trimedlure isomer, ceralure, 4-[(4-acetyloxy)phenyl]-2-butanone, methyleugenol, a fluorinated methyleugenol analogue, l,7-dioxaspiro-5,5-undecane and mixtures thereof, trimedlure and any of its isomeric combinations, ceralure and any of its isomeric combinations, 4-[(4-acetyloxy)phenyl]-2-butanone, methyleugenol or fluorinated methyleugenol analogues, and 1,7-dioxaspiro-5,5-undecane.

[0023] In some aspects, the bait may include nutritional feeding stimulants as the flavorant (phagostimulants) component to give a taste and flavor to the bait composition and / or to enhance feeding by the target insects. Such nutritional feeding stimulants may include, e.g., fatty acids, amino acids, sugars, carbohydrates, pectins, starches, salts, chitins, essential plant oils and the like. For example, suitable phagostimulants are peanut butter oil, apple cider vinegar, extracts from meat, fish or insects. Others which are suitable for attraction are certain natural or synthetic aroma substances such as, for example, meat aromas, fish aromas, seafood aromas, onion aroma, milk aroma, butter aroma, cheese aromas, fruit aromas such as, for example, apple, apricot, banana, blackberry, cherry, currant, gooseberry, grapefruit, raspberry or strawberry (pure, syrup or extract).

[0024] Non-food based attractants can also be used. For example, pheromones such as sex pheromones that can be used to attract insects of the opposite sex for mating purposes (e.g., moths, beetles) can be used. Some examples are Codlemone (Cydia pomonells) and Glypure (Lymantria dispar). Aggregation pheromones that attract both sexes for aggregation can also be used. Some examples are Granlure (Anthonomus grandis, Verbenone (Dendroctonus species). Others, for example, alarm pheromones that can either repel or attract depending on the speciescan be used in some instances. Examples include E-beta-farnesene (aphids). Kairomones, chemicals emitted by one species and exploited by another species to locate their host or prey can be used in the bait compositions disclosed herein. One such example is volatiles from plant tissues damaged by herbivores that attract predators or parasitoids of the herbivore. Chemicals that benefit the emitter by repelling or deterring the enemies, but some can be attractive to other organisms, which are referred to as allomones can be used. For example, certain defensive secretions from insects that may attract parasitic species. Plant volatiles, which are plant-emitted compounds that attract pest or their natural enemies can also be used; some examples are methyl salicylate (attracts natural enemies of pests, and Eucalyptus oil (attracts certain beetles). Another common non-food based attractant is carbon dioxide (or agents that emit carbon dioxide) that can attract blood-feeding pests such as mosquitoes and ticks. Color or light attractants, UV light or certain specific colors can be used to attract pests. For example, yellow sticky traps attract many flying insects such as aphids, whiteflies and leafhoppers. Hormones, synthetic or naturally-occurring growth regulators that can attract pests by mimicking physiological conditions can be used to attract pests. An example is juvenile hormone analogs that can be used to lure mosquitoes or other pests during their breeding phases. Certain symbiotic bacteria, such as Serrata marcescens, produce odors that can attract mosquitoes and other blood-feeding insects. The above-mentioned pest attractants can be used in the bait compositions disclosed herein to trap or kill specific pests.

[0025] In some aspects, antioxidizing agents and preservatives can be included in the bait compositions. Examples of the antioxidizing agents are erythorbic acid, sodium erythorbate, ditert-butyl hydroxytoluene (BHT), tert-butyhydroquinone (TBHQ), dl-alpha-tocophelol, nordihydroguaiaretic acid, methylhydroxyanisole, propyl gallate, guaiac resin, L-cysteine hydrochloride, butylated hydroxyanisole (BHA), and mixed tocopherols.

[0026] Formulations

[0027] The bait compositions comprising either the compound of Formula One (I) or the compound of Formula Two (II) can be converted into customary types of compositions, e.g. solutions, emulsions, suspensions, dusts, powders, pastes, granules, pressings, capsules, and mixtures thereof. Examples for composition types are suspensions (e.g. SC, OD, FS), emulsifiable concentrates (e.g. EC), emulsions (e.g. EW, EO, ES, ME), capsules (e.g. CS), pastes (e.g. PA), pastilles, hot-melt extrusions, wettable powders or dusts (e.g. WP, SP, WS, DP, DS), pressings (e.g. BB, BR, TB, DT), granules (e.g. WG, SG, GR, FG, GG, MG), insecticidal articles (e g.

[0044] Suitable pH modifiers that provide certain benefits such as processability, stability, extended shelflife and storage can be added. In some embodiments, the pH modifiers help to maintain a specific pH range. In some embodiments, the pH modifiers can maintain the pH range from 4.0 - 8.0. In some other instances, the pH modifiers can maintain the pH range from 5.0 - 7.0. In some other instances, the pH modifiers can maintain the pH range from 5.0 -6.5. In some other instances, the pH modifiers maintain an acidic pH range in the medium. pH modifiers can provide several advantages; for example, optimizing the active ingredients stability as a pH modifier ensures that the composition remains within a pH range that maintains the chemical stability of the active ingredient prolonging the shelf life and effectiveness. In some instances, the activity of certain ingredients is influenced by pH. For example, some pesticides are more effective at specific pH levels. A pH modifier adjusts the solution to the optimal range for maximum bioactivity. In some instances, the pH modifiers help in improving solubility as some active ingredients or formulation components have pH-dependent solubility. Adjusting the pH ensures that these components remain dissolved, preventing precipitation or phase separation. pH modifiers can also improve the compatibility with tank mixes, for example, pesticides are often mixed with other chemicals or fertilizers before application. pH modifiers help maintain compatibility and prevent unwanted chemical reactions that could reduce efficacy or form insoluble residues. pH modifiers, in some instances, can also reduce phytotoxicity, for example,extreme pH levels in a spray solution can harm plants. A pH modifier ensures that the formulation is safe for crops by maintaining a pH within an acceptable range, n multi-phase formulations like emulsifiable concentrates or suspensions, pH modifiers can stabilize the emulsion or suspension by controlling the charge and interactions of the dispersed particles.

[0045] In some instances, the pH modifiers are acidic pH modifiers including carboxylic acids such as citric acid, acetic acid, lactic acid, oxalic acid or tartaric acid; inorganic acids such as phosphoric acid, hydrochloric acid, sulfuric acid or nitric acid; sulfonic acids such as methanesulfonic acid, p-toluenesulfonic acid. In other instances, basic pH modifiers such as sodium hydroxide, potassium hydroxide, calcium hydroxide or magnesium hydroxide can be used. Ammonium compounds such as ammonium hydroxide or ammonium carbonate can be used in some instances. In some instances, carbonates and bicarbonates such as sodium carbonate, potassium carbonate or sodium carbonate can be used. Buffering agents such as sodium hydrogen phosphate, disodium hydron phosphate and potassium phosphate can also be used. Carbonate / bicarbonate buffers such as sodium carbonate / sodium bicarbonate combinations can be used. Organic buffer systems such as citric acid / sodium citrate or acetic acid / sodium acetate combinations can also be used. The choice of pH modifier depends on many factors, for example, the desired pH range, the chemical compatibility with active ingredients and other excipients and the formulation type.

[0046] For use in bait compositions, the typical amount of the active ingredient (compound of Formula One (I) or compound of Formula Two (II)) is from 0.001 weight % to 50 weight %. In some aspect, the amount of the active ingredient is from 0.01 weight % to 50 weight %. In some other instances, the amount of the active ingredient is from 0.01 weight % to 40 weight %. In some other instances, the amount of the active ingredient is from 0.01 weight % to 30 weight %. In other instances, the amount of the active ingredient is from 0.01 weight % to 20 weight %. In some other instances, the amount of the active ingredient is from 0.01 weight % to 10 weight %. In other instances, the amount of the active ingredient is from exO. Ol weight % to 5 weight %.

[0047] The bait composition can be a liquid, a solid or a semisolid preparation (e.g. a gel). Solid baits can be formed into various shapes and forms suitable to the respective application e.g.granules, blocks, sticks, disks. Liquid baits can be filled into various devices to ensure proper application, e.g. open containers, spray devices, droplet sources, or evaporation sources. Gels can be based on aqueous or oily matrices and can be formulated to obtain desired stickiness, moisture retention or aging characteristics.

[0048] In some aspects, the bait composition is formulated to use as an aerosol or spray application (AE).

[0049] Bait compositions comprising compound of Formula I or Formula II can be formulated as aerosols (e.g. in spray cans). Oil sprays or pump sprays are highly suitable for the professional user for controlling pests such as flies or cockroaches. Aerosol recipes are preferably composed of the active compound, solvents such as lower alcohols (e.g. methanol, ethanol, propanol, butanol), ketones (e.g. acetone, methyl ethyl ketone), paraffin hydrocarbons (e g. kerosene) having boiling ranges of approximately 50 to 250° C., dimethylformamide, N-methylpyrrolidone, dimethyl sulfoxide, aromatic hydrocarbons such as toluene, xylene, water, furthermore auxiliaries such as emulsifiers such as sorbitol monooleate, oleyl ethoxylate having 3-7 mol of ethylene oxide, fatty alcohol ethoxylate, perfume oils such as ethereal oils, esters of medium fatty acids with lower alcohols, aromatic carbonyl compounds, if appropriate stabilizers such as sodium benzoate, amphoteric surfactants, lower epoxides, triethyl orthoformate and, if required, propellants such as propane, butane, nitrogen, compressed air, dimethyl ether, carbon dioxide, nitrous oxide, or mixtures of these gases.

[0050] The oil spray formulations differ from the aerosol recipes in that no propellants are used. For use in spray compositions, the content of active ingredient is from 0.001 to 80 weights %, preferably from 0.01 to 50 weight % and most preferably from 0.01 to 20 weight %.

Higher potency of Compound I was oberserved 48 h after the infestation at 0.1% rate. At 72 h both 0.05% and 0.1% showed 100% of mortality for Compound I.EXAMPLE 4

[0097] Bait preparation. The bait was prepared using a method known to those skilled in the art. A blend of invert sugar, corn steep liquor, ammonium acetate, and water was mixed with a suspension concentrate (Table 2) of Compound I. Commercial standard of Spinosad fruit fly bait, Naturelyte, was used.

[0098] This example demonstrates the activity of Compound I formulated as a bait concentrate (CB) at 0.24 g of Compound I / L of bait (0.02% by weight) for fruit fly Ceratitis capitata control in orange orchard. Two field trials were carried out diluting 1 part of bait+ Compound I with 1.5 parts of water, with application of 3-4 L of bait / ha. Three applications were performed using a gum sprayer in 1 m2per plant every 7 meters with very coarse droplets (4-6 cm of diameter with 60 to 80 droplets / m2). The standard Spinosad (CB with Spinosad at 0.24 g ai / L) followed the same dilution and method of application. The control treatment was composed by untreated plants. Around 20 plants per plot were sprayed per treatment. The interval between applications was 14 to 21 days. The damaged fruits by fruit fly on trees and fallen fruits damaged were assessed 7 days after the third application (Table 6).Table 6.

[0099] Bait preparation. A blend of masa flour and Compound I were extruded using paste extrusion following known methods to those skilled in the art.

[0100] This example demonstrates the efficacy of ready to use bait (RB ) impregnated with Compound I (4 g of Compound I / kg of RB) for wireworm Agriotes spp. control in potato. A field trial was carried out with application of Compound I + RB in furrow (before planting) at rates of 50, 75 and 100 g of Compound I / ha. The standard treatments where tefluthrin (15 g ai / kg) at 150 g ai / ha and cypermethrin (8 g ai / kg) at 96 g ai / ha, both applied in furrow. The assessment of incidence of damaged tubers was recorded at harvest (120 days after planting) (Table 7).Table 7. Efficacy of Compound I +RB for wireworm damage control in potato (average of 2 field trials).Treatments EfficacyCompound I+ RB - 50 g ai / ha 48% Compound I + RB - 75 g ai / ha 52%Compound I + RB - 100 g ai / ha 50%Teflutrin - 150 g ai / ha 42%Cypermethrin - 96 g ai / ha 35%The field performance of both Compound I + RB showed superior performance to both standards tefluthrin and cypermethrin. These results demonstrate the superior efficacy of both inventions versus the standards.EXAMPLE 6

[0101] Example 6 describes the unprecedented control and strong potency of Compound I on leaf-cutting ant Atta sexdens rubropilosa L. (Hymenoptera, Formicidae) with a bait comprising Compound I in very low concentrations. The concentrations of 1%, 0.1%, and 0.01% v / v demonstrated to be very effective on control the leaf-cutting ant A. sexdens rubropilosa,compared to the main standard sulfluramide. Also, the method used is the same utilized by other companies to determine intrinsic activity and register their products against this type of pest. The test has important particularities, because the insecticides cannot kill the worker ants too fast, allowing the workers ants carry the bait into the colony to feed the fungus, where the ants keep this fungus as the feed source for all the ants in the colony. Compound I showed all the characteristics necessary to be considered and used as formicide bait for this species, showing mortality <15% in 24 hours and >90% in 21 days. These laboratory tests, using attractive pastes demonstrated that Compound I reduces worker ant populations, thereby limiting the pest’s ability to reproduce and cause crop damage, with results compared to the standard sulfuramide. This effect can be extrapolated to other species like Atta capiguara, Atta sexdens sexdens, Atta bisphaerica, Atta laevigata, Atta robusta and Atta opaciceps. The complex of leaf cutting ants is an endemic pest in Latin America and represents a significant agricultural threat to several crops such as Eucalyptus spp., Pinus spp., pastures, sugarcane and orchards.

[0102] The baits were formulated as carry-attractive pastes for ingestion, based on citrus pulp powder, sucrose p.a., and distilled water. All formulations were prepared at a w / w (weight / weight) ratio. Compound I (technical material) was tested at the concentrations of 1%, 0.1% and 0.01% w / w and compared to Sulfuramide at 0.1% (current standard) and untreated. The applications were made applying 1 gram of formulated bait per replicate (4 replications). The treated baits were removed after 24 hours, followed by the provision of approximately 3 cm3of fungal sponge, which served as a food source, plus approximately 20 gardening workers ants (2 mm in body length) to grow and maintain the fungus. Whenever a substantial reduction in fungal sponges or live planters was observed, it was replaced to avoid the influence of food deficiency on the survival of the worker ants.

[0103] Results: The number of dead worker ants was assessed 1, 2, 3, 5, 7, 9, 11, 14, 17, and 21 days after insecticide application. The data were submitted to ANOVA and the averages of dead worker ants submitted to Tukey test (p>0.05). All concentrations of Compound I controlled A. sexdens rubropilosa as good as or better than sulfluramide. The lowest concentration (0.01% w / w) attended the expected efficacy for a formicide bait, killing <15% in 24 hours and >90% in 21 days (Figure 1).

[0104] This example demonstrates the efficacy of ready to use bait (RB ) impregnated with Compound I (4 g of Compound I / kg of RB) for wireworm Agriotes spp. control in potato.
