Description

Liquid compositions comprising neonicotinoids
Technical Field
The present disclosure relates to liquid agrochemical compositions comprising a neonicotinoid insecticide, methods of making the liquid agrochemical compositions, the use of the liquid compositions for controlling pests, and methods of controlling pests using the liquid agrochemical compositions.
Background
The neonicotinoid pesticide has a unique action mechanism. Unlike pesticides, which evaporate or disperse soon after application, neonicotinoid insecticides are systemic pesticides. They are less toxic than organic phosphates and carbamates, which provide similar broad spectrum control over many crop-damaging insects. Neonicotinoid insecticides paralyze insects by blocking pathways in the insect central nervous system that transmit nerve impulses. Neonicotinoid insecticides are used to control a wide variety of insects. Typical neonicotinoid insecticides are imidacloprid, acetamiprid, clothianidin, dinotefuran, nitenpyram, thiacloprid and thiamethoxam.
Acetamiprid is a neonicotinoid pesticide used for foliar spray and seed treatment. Acetamiprid is slightly soluble in water and therefore its liquid formulations often exhibit stability problems. Suspension Concentrate (SC), emulsifiable Concentrate (EC) and Microemulsion (ME) formulations of acetamiprid are known to have stability problems. Emulsifiable concentrates are stable liquid, homogeneous liquid formulations comprising an insecticidal active ingredient, a solvent and an emulsifier. When diluted with water, they form an emulsion upon dilution in water. The stable suspension contains the active ingredient in a continuous phase with water and is intended to be diluted with water before use. The microemulsion comprises the active ingredient, oil and water and may be applied directly or after dilution in water.
Suspension Concentrate (SC) formulations comprising acetamiprid are known to be prone to rapid formation of crystals, gelation, caking and sedimentation. Emulsifiable Concentrate (EC) formulations comprising acetamiprid are known to crystallize and cause nozzle clogging upon dilution with water. Microemulsions (ME) containing acetamiprid also face stability problems and require large amounts of surfactants to achieve thermodynamic stability. These problems are further exacerbated when formulators attempt to achieve high loadings of active ingredient in acetamiprid liquid formulations alone or in combination with other active ingredients that can withstand extreme temperatures, especially low temperatures.
There is a need to develop stable agrochemical compositions comprising neonicotinoid insecticides which do not present stability problems and are stable at low temperatures.
The purpose of the disclosure is as follows:
it is an object of the present disclosure to provide stable liquid agrochemical compositions comprising a neonicotinoid insecticide.
It is another object of the present disclosure to provide stable liquid agrochemical compositions comprising high load neonicotinoid insecticides alone or in combination with additional pesticides.
It is a further object of the present disclosure to provide stable liquid agrochemical compositions capable of withstanding low temperatures comprising high loadings of neonicotinoid insecticides alone or in combination with additional pesticides.
It is a further object of the present disclosure to provide a method of preparing a liquid agrochemical composition comprising a high load neonicotinoid insecticide alone or in combination with an additional pesticide.

Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All endpoints of the ranges are inclusive of the range and independently combinable. As used herein, unless the context clearly indicates otherwise, all numbers or ranges of numbers include integers within such ranges as well as values or fractions of integers within the range. Thus, for example, reference to a range of 90% -100% includes 91%, 92%, 93%, 94%, 95%, 97%, etc., as well as 91.1%, 91.2%, 91.3%, 91.4%, 91.5%, etc., 92.1%, 92.2%, 92.3%, 92.4%, 92.5%, etc., and the like. All methods described herein can be performed in the proper order unless otherwise indicated herein or otherwise clearly contradicted by context.
As used herein, "a," "an," "the," and "at least one" do not denote a limitation of quantity and are intended to cover both the singular and the plural, unless the context clearly indicates otherwise. For example, "an element" has the same meaning as "at least one element" unless the context clearly indicates otherwise. As used herein, the terms "first," "second," and the like are not intended to denote any particular order, but rather merely for convenience to denote multiple layers, for example. As used herein, the terms "comprising," "including," "having," "containing," "involving," and the like are to be construed as open-ended, i.e., to mean including but not limited to, unless otherwise noted. As used herein, "about" or "approximately" includes the specified values and means within an acceptable deviation of the specified values, which is determined by one of ordinary skill in the art in view of the measurement in question and the specified amount of error associated with the measurement (i.e., limitations of the measurement system). For example, "about" may mean within one or more standard deviations, or within a range of ±10% or ±5% of the specified value. The use of any and all examples, or exemplary language (e.g., "such as") provided herein, is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention as used herein.
In any aspect or embodiment described below, the phrase "comprising" may be replaced by the phrase "consisting of … …" or "consisting essentially of … …" or "consisting essentially of … …". In these aspects or embodiments, the described compositions comprise or consist of or consist essentially of the specific components recited therein, excluding other ingredients or excipients specifically recited therein.
While the disclosure has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure.

The invention encompasses any combination of the above-described elements in all possible variations thereof unless otherwise indicated herein or otherwise clearly contradicted by context.
"alkyl" means a straight or branched chain saturated aliphatic hydrocarbon having the specified number of carbon atoms, specifically 1 to 12 carbon atoms, more specifically 1 to 6 carbon atoms. Alkyl groups include, for example, groups having 1 to 50 carbon atoms (C 1 To C 50 Alkyl).
"alkylene" means a straight or branched, saturated divalent aliphatic hydrocarbon group (e.g., methylene (-CH) 2 (-) or propylene (- (CH) 2 )3-))。
As used throughout this disclosure, neonicotinoid insecticides or other active ingredients include their salts, esters, ethers, isomers, and polymorphs including solvates and hydrates. Salts include those which retain the biological effectiveness and properties of the active ingredient and are not biologically or otherwise undesirable, and include derivatives of the disclosed compounds wherein the parent compound is modified by preparing inorganic and organic, non-toxic acid or base addition salts thereof. Salts can be synthesized from the parent compound by conventional chemical methods. "solvate" means a pesticide or agriculturally acceptable salt thereof in which a molecule of a suitable solvent is incorporated into the lattice. Suitable solvents are physiologically tolerable at the doses administered. Examples of suitable solvents are ethanol, water, and the like. When water is the solvent, the molecule is referred to as a "hydrate". The formation of solvates will vary depending on the compound and the solvate. In general, solvates are formed by dissolving the compound in an appropriate solvent and isolating the solvate by cooling or using an antisolvent. The solvates are typically dried or azeotroped at ambient conditions. In one aspect, the solvate is a hydrate.
The term "plant" refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, leaves, and fruits. The term plant includes transgenic plants and non-transgenic plants.
The term "locus" as used herein refers to the vicinity, region or site of plant growth, plant propagation material in which plants are sown (e.g., placed in soil), and/or plant propagation material in which plants are to be sown.
The term "plant propagation material" refers to reproductive parts of plants, such as seeds, nutritional materials, such as cuttings or tubers, roots, fruits, tubers, bulbs, rhizomes, and other parts of plants, germinated plants and/or seedlings, which are transplanted after germination or after emergence from soil. These seedlings may be protected by a complete or partial soaking process/system prior to transplantation.
As used herein, an "effective amount" is an amount of an active ingredient (such as a combination disclosed) that has an adverse effect on the insect and/or that prevents diseases caused by the insect in the plant. Adverse effects may include killing the insect (insecticidal), preventing insect growth, blocking biosynthetic pathways, or combinations thereof.
As used herein, "agriculturally acceptable salt" means a salt that has been accepted for agricultural or horticultural use.
Low temperature stability is a critical requirement for liquid agrochemical formulations (such as EC and ME) because they often need to be used in low temperature areas or exposed to low temperatures. In cold climates, precipitation of active substances at low temperatures or freezing of such liquid formulations can lead to practical difficulties in handling the product and to low biological efficacy. Stability, particularly low temperature stability, is of great concern when liquid formulations are exposed to low temperatures, i.e., from about 20 ℃ to about-10 ℃.
Surprisingly, the inventors of the present disclosure have found that liquid agrochemical compositions of stable neonicotinoid insecticides, alone or in combination with additional pesticides, can be obtained by incorporating a low polarity amide solvent and a surfactant having an HLB value of from about 10 to about 18. The inventors have also found that by combining a low polarity amide solvent with a surfactant having an HLB value of 10-18, a high loading of a neonicotinoid insecticide in a liquid agrochemical composition is possible. The highly loaded compositions thus obtained were found to be able to withstand extremely low temperatures and to remain fairly stable throughout storage and during application after dilution with water.
