[0001] PESTICIDAL COMPOSITIONS
[0002] This invention relates to compositions comprising pesticidal isoxazoline derivatives. More particularly, this invention relates to compositions of isocycloseram; to dilutions or dispersions of such compositions; and to the use of such compositions to combat and / or control invertebrate animal pests such as arthropods.
[0003] Isocycloseram is pesticide that is solid at room temperature (25°C). It is convenient to prepare isocycloseram as a fine suspension of dispersed particles in a liquid medium, typically by milling isocycloseram to produce a millbase which may then be further processed by the addition of other ingredients to prepare aqueous suspension concentrates (SC). Such aqueous SCs can either be used directly or diluted prior to use for controlling arthropods such as insects or arachnids.
[0004] A common method for controlling insect or arachnid pests in non-crop areas such as the inside and outside of buildings and houses is by applying an aqueous pesticide composition to surfaces found in or around such structures. However, the efficacy of the pesticide surface spray coating and its residual effect can be reduced on porous surfaces including aggressive (i.e., alkaline) porous surfaces.
[0005] There remains a need for isocycloseram compositions that are easy to handle and can be used to prepare aqueous compositions that are suitable for application to porous or aggressive surfaces for longer-lasting control of arthropod pests.
[0006] Therefore, the present invention provides isocycloseram compositions comprising an absorptive carrier. The isocycloseram compositions have improved efficacy and residual activity against arthropod pests on porous or aggressive surfaces.
[0007] In a first aspect, the present invention is directed to a pesticidal composition comprising:
[0008] (a) isocycloseram;
[0009] (b) a solvent;
[0010] (c) an absorptive carrier; and
[0011] (d) a surfactant.
[0012] Further according to the invention, there is provided a pesticidal composition comprising the components (a) - (d), and optionally further comprising one or more of (e) a filler or carrier, (f) an antifoam, (g) a thickener and (h) a preservative.
[0013] The pesticidal composition according to the invention further relates to suspension concentrates (SC), flowable suspensions (FS), suspoemulsions (SE), suspension concentrate-capsule suspension blends (ZC), water soluble granules (SG), water dispersible granules (WG), and water dispersible tablets (WT); to dilutions or dispersions of such compositions more particularly in a spray tank, back-pack sprayer or other vessel; and to the use of such a composition to combating and / or control an arthropod pest.
[0014] In a preferred embodiment, the pesticidal composition according to the invention relates to a water dispersible solid in the form of a wettable powder (WP) or a wettable granule (WG) such as a water dispersible granule (WDG), usually intended for dilution with water before use as an aqueous spray composition.
[0015] In another preferred embodiment, the pesticidal composition according to the present invention is a suspension concentrate (SC), which is a stable suspension of a solid pesticidal active ingredient compound in a liquid, usually intended for dilution with water before use as an aqueous spray composition.
[0016] Still further according to the invention, there is provided a (non-therapeutic) method of combating and controlling arthropod pests which comprises applying to a pest, to a locus of a pest (eg soil, mud or a surface such as a porous or aggressive surface), or to a crop of a useful plant susceptible to attack by a pest a composition according to the invention.
[0017] The pesticidal composition of the invention is particularly suited for controlling insect pests and insect populations including flying, crawling, social or communal insect pests, pests on porous or aggressive surfaces.
[0018] In one embodiment, the flying insect pests to be controlled are mosquitoes including nuisance mosquitoes, mosquito vectors of pathogenic disease and mosquitoes having resistance to insecticides such as pyrethroids.
[0019] Aqueous spray compositions prepared from the pesticidal compositions of the invention show significant improvements in efficacy and residual activity on porous / aggressive surfaces including, for example, wood, unglazed tile, or concrete.

[0141] Pyrethroids are the only insectides that have obtained WHO recommendation against Malaria vectors on both Indoor Residuals Sprays (IRS) and Long Lasting Insecticidal Mosquito Nets (LLINs), in the form of Alpha-Cypermethrin, Bifenthrin, Cyfluthrin, Permethrin, Deltamethrin, Lambda-Cyhalothrin and Etofenprox. It has been the chemical class of choice in agriculture and public health applications over the last several decades because of its relatively low toxicity to humans, rapid knock-down effect, relative longevity (duration of 3-6 months when used as IRS), and low cost. However, massive use of pyrethroids in agricultural applications and for vector control led to the development of resistance in major malaria and dengue vectors. Strong resistance has e.g. been reported for the pyrethroid Deltamethrin (and Permethrin) for the Anopheles gambiae Tiassale (from southern Cote d'Ivoire) strain (Constant V.A. Edi et al., Emerging Infectious Diseases; Vol. 18, No. 9, September 2012). Pyrethroid resistance was also reported for Permethrin, Deltamethrin and Lambda-Cyhalothrin for the Aedes aegypti Cayman Island strain (Angela F. Harris et al., Am. J. Trop. Med. Hyg., 83(2), 2010) and Alpha- Cypermethrin, Permethrin and Lambda-Cyhalothrin for certain Anopheles strains (Win Van Bortel, Malaria Journal, 2008, 7:102).
[0142] In another embodiment of the invention, the isocycloseram compositions of the invention (preferably the WP) are suitable for use against insecticide-resistant mosquitoes that are selected from Anopheles gambiae RSPH, Anopheles gambiae Tiassale, Anopheles gambiae Akron, Anopheles gambiae Kisumi Rdl, Anopheles arabiensis NDjamina, Anopheles coluzzii VK7, Anopheles funestus FUMOZ, Aedes aegypti Grand Cayman, Culex quinquefasciat us strain POO and highly pyrethroid resistant Anopheles arabiensis (Kingani Strain).

[0154] For mosquito control, the compositions of the present invention also can be applied to soil, mud or a to surface such as a porous or aggressive surface by indoor residual spray or the like, for example, after dilution with water before use as an aqueous spray composition. In one embodiment, an aqueous spray composition prepared from a composition of the present inventionis applied to the target pests, to their locus or to a surface or substrate by brushing, rolling, spraying, spreading or dipping. By way of example, an IRS (indoor residual spraying) application of a surface of a dwelling such as an indoor surface including a wall, ceiling or floor surface is a contemplated (non-therapeutic) use of the compositions of the present invention. Such IRS applications are particularly suited for mosquito control when applied to a locus which is an area of potential or known interaction between a human or mammal and the mosquito, which includes a to locus where a mosquito will rest or can be expected to contact after taking a blood meal (IRS locus). Although the compositions can be applied directly, as noted above, these are typically applied after dilution with water before use as an aqueous spray composition.
[0155] In one embodiment, a method for controlling such pests (including mosquito pests) comprises applying a pesticidally effective amount of the compositions of the invention to the target pests, to their locus, or to a surface or substrate so as to provide effective residual pesticidal activity on the surface or substrate. Such application may be made by brushing, rolling, spraying, spreading or dipping the pesticidal composition of the invention. By way of example, an IRS application of a surface such as a wall, ceiling or floor surface is contemplated by the method of the invention so as to provide effective residual pesticidal activity on the surface.
[0156] In another aspect, the compositions of the present invention can be used to controlling crawling insect pests such as cockroach or ant pests. The compositions can be applied to soil, mud or a to surface such as a porous or aggressive surface or the like, for example, after the composition is diluted with water before use as an aqueous spray composition. In one embodiment, the compositions of the invention can be used to control crawling insect pests or populations by application to an indoor or outdoor environment or locus of known or suspected crawling insect foraging, infestation, or harborage sites. Direct applications including as a spot or crack-and-crevice can be made to areas including, but not limited to, pest entry sites, attics, wall voids, behind cabinets or equipment, under counters or under / behind appliances, and along baseboards and reticulation systems. In another embodiment, a method of controlling crawling insect pests or populations comprises application to an indoor or outdoor environment or locus of known or suspected foraging, infestation or harborage, including application as a spot or crack-and-crevice to exterior structural elements and also outdoor breeding sites, such as refuse collection areas, loading docks, adjacent tree holes, crawl spaces, or other sources of crawling insect infestations.
[0157] In another embodiment, crops of useful plants in which the compositions according to the invention can be used include perennial and annual crops, such as berry plants for example blackberries, blueberries, cranberries, raspberries and strawberries; cereals for example barley, maize (corn), millet, oats, rice, rye, sorghum triticale and wheat; fibre plants for example cotton, flax, hemp, jute and sisal; field crops for example sugar and fodder beet, coffee, hops, mustard, oilseed rape (canola), poppy, sugar cane, sunflower, tea and tobacco; fruit trees for example apple, apricot, avocado, banana, cherry, citrus, nectarine, peach, pear and plum; grasses for example Bermuda grass, bluegrass, bentgrass, centipede grass, fescue, ryegrass, St. Augustine grass and Zoysia grass; herbs such as basil, borage, chives, coriander, lavender, lovage, mint, oregano, parsley, rosemary, sage and thyme; legumes for example beans, lentils, peas and soya beans; nuts for example almond, cashew, ground nut, hazelnut, peanut, pecan, pistachio and walnut; palms for example oil palm; ornamentals for example flowers, shrubs and trees; other trees, for example cacao, coconut, olive and rubber; vegetables for example asparagus, aubergine, broccoli, cabbage, carrot, cucumber, garlic, lettuce, marrow, melon, watermelon, okra, onion, leek, pepper, potato, pumpkin, squash, rhubarb, spinach and tomato; and vines for example grapes. The compositions of the invention can also be applied on turf, lawn and pastures.
[0158] As noted above, in one embodiment, the compositions of the invention are applied by spraying the composition after dilution with water, for example dispensed from a spray container.
[0159] Said use or method of use can involve an effective amount of the isocycloseram in the spray composition which is applied at a rate of from 0.01 to 5 Litre per Hectare (L / ha), and more preferably from 0.02 to 3.0 L / ha.
[0160] In one embodiment, the compositions of the invention are used to control crawling insects or mosquitoes by application to a locus (such as an indoor, outdoor, soil, mud or other porous or aggressive surface) after the composition is diluted with water before use as an aqueous spray composition. For mosquito control or flying insects, in one embodiment, the spray composition can be applied, for example, at a rate of 50 to 200 mg a.i / m2 (preferably 100 to 175 mg a.i / m2; or 120) and for crawling insects the spray composition can be applied, for example, at a rate of from 10 to 100 Al / m2.
[0161] The pesticidal compositions of the present invention may be prepared according to standard procedures known in the art and as further described herein. Example 1
[0162] This example provides a composition, which is a wettable powder (i.e. isocycloseram wettable powder) and which may be used to prepare further compositions or formulations. The wettable powder of Example 1 can include well-known formulation additives such as a suitable solvent, dispersant, wetting agent, and anti-foam agent.
[0163] N,N-dimethyl lactamide is heated in a jacketed formulation vessel to 38°C. Isocycloseram is added to the vessel, stirring with a sawtooth mixer and / or bulk agitator. The mixture was sheared continuously until the isocycloseram completely dissolved.
[0164] Precipitated silica (with a high absorption capacity) is added to a ribbon blender equipped with spray capabilities. The solution of N,N-dimethyl lactamide with solubilized isocycloseram is slowly sprayed onto the silica in the ribbon blender until applied at the given rate. The material is mixed until homogenous with no lumps. The remaining co-formulants such as wetting agents, dispersants, antifoaming agent, and other dry carriers such as lactose monohydrate, were added, to the ribbon blender while continuing mixing. The entire blend is then passed through a hammer mill (screen size
[0165] O.035”) to ensure proper homogeneity and particle size (Dv95 <40 pm, Malvern Mastersizer 3000, laser diffraction particle size analyser).
[0166] The concentrations of the components added to form the isocycloseram wettable powder of Example 1 are listed in the below Table 1 and are expressed in percentage by weight over the total weight of the isocycloseram wettable powder (% w / w).

[0175] Treatment list:
[0176] Material & methods Samples were applied to 10 x 10 cm glazed ceramic tiles and 9cm diameter cement plaques using a laboratory tracksprayer calibrated to give an even deposit of 40 ml / m2, using an 8003 flat fan nozzle. Formulations were diluted / suspended to the correct concentration using de-ionised water. Diluted samples were vigorously shaken prior to application to ensure the formulation was fully suspended. After application, treated surfaces were stored in a ventilated room at 26oC and ambient humidity under low light conditions.
[0177] Insecticidal activity was bioassayed using ten adult female mosquitoes, 3 - 5 day old, Anopheles stephensi, exposed to the treated surface for one hour. After one hour an assessment of knockdown was made, the mosquitoes were then transferred to holding cups and provided with a small cotton wool bung soaked in 10% sucrose solution. Assessments of mortality were made at 24, 48 and 72 hours after exposure. Six replicates of each treatment were employed. Assessments were made at 1 , 2, 4, 8 and 12 weeks after treatment.
