Description

[0001] The present invention relates to an agrochemical composition, in particular to a composition comprising a pesticidally active pyrazole derivative, more particularly to the aforementioned composition further comprising an adhesion promoter. The present invention also relates to the use of the aforementioned composition, in particular in the treatment of seeds.

[0002] Numerous technologies are currently used to treat seeds in order to increase crop performance. These treatments include, among others, coating, pelletizing and / or extra layer of seed film. A range of agrochemical compositions in the form, for example, of powders, liquids and pastes has long been used to control soil-borne and seed-borne diseases, as well as seed pests.

[0003] Recent developments in seed treatment technology have focused on using techniques to deliver pesticides to seeds. One of the common techniques is to coat seeds with agrochemical formulations. In particular, it is common for crop producers to apply agrochemically active ingredients to seeds, especially for the protection of seeds against diseases and pests, and / or to increase the yields of eventual crops. These agrochemically active ingredients can be applied to the soil before sowing the seeds or can be applied directly to the seeds before being sown. The agrochemically active ingredients applied to seeds can protect buds and seedlings against diseases and pests in the post-germination and seedling stages, for example. However, in regions with high humidity soil and / or during the rainy season, there is the problem of bleaching of the agrochemically active ingredients from the seeds, leading to a significant decrease in the amount of active ingredients left in the seeds, which in turn instead decreases the effectiveness of the agrochemically active ingredients in the seeds. In addition, even small amounts of agrochemically active ingredients leached from seeds pretreated in this way and present in the rainwater that drips can cause problems of environmental pollution.

[0004] To address the above problems, agrochemical compositions containing 1-aryl pyrazoles and a hyper-branched polymer with high molar mass have been disclosed in US 6,232,294. The purpose of these compositions is to improve the adhesion properties of the active ingredients on the seeds. In particular, US 6,121,193 discloses an agrochemical composition comprising 0.5 to 50% by weight of at least one 1-aryl pyrazole of a given formula and an effective amount of a hyper-branched polymer with high molar mass. The hyperbranched polymer is preferably in the form of an aqueous suspension. Hyperbranched polymers disclosed in US 6,121,193 are polyethylene amines, polyamide amides, polyethylene imines, polyethers and copolymers derived therefrom. US 6,121,193 particularly prefers hyper-branched polymers of imine polyethylene, with this being the only hyper-branched polymer specifically described and exemplified.

[0005] However, although the adhesion properties of the US 6,121,193 1-aryl pyrazole compositions can be improved, the viscosity of such compositions is greatly increased. This increase in viscosity makes the application process more difficult and time-consuming. In addition, the coating formed on the seeds is also irregular.

[0006] Therefore, there is a need for an improved agrochemical formulation for seed treatment. It would be advantageous if the formulation had a viscosity such that application of the formulation to seeds was made easier and faster and the resulting coating on the seeds could be more uniform. It would be particularly advantageous if these properties could be obtained while maintaining the formulation's adhesion to the seeds and without reducing the effectiveness of the active ingredients.

[0007] It has now been found that a particularly advantageous formulation of 1-aryl pyrazoles for seed treatment can be formed by combining pyrazole derivatives with a polyether having at least 16 polyoxyethylene fractions therein.

[0008] According to a first aspect of the present invention an agrochemical composition is provided comprising:

[0009] A) at least one agrochemical active ingredient of 1-aryl pyrazoles of formula (I)

[00010] In which:

[00024] With the proviso that when R4 is methyl, then R3 is haloalkyl, R4 is NH2, RX1 is Cl, R13 is CF3 and X is N; or R2 is 4,5-dicianoimidazol-2-yl, R4 is Cl, Rn θ Cl, Ria and CF3 and X and C-Cl; and

[00025] B) one or more adhesion promoters comprising a polyether or polyether containing at least 16 fractions of polyoxyethylene.

[00026] Polyethers having at least 16 polyoxyethylene fractions have been found to provide advantageous adhesion of the formulation 1-aryl pyrazole to seeds being treated, without resulting in a significant increase in the viscosity of the formulation and without reducing the effectiveness of the active ingredient.

[00027] It has also been found that a formulation of 1-aryl pyrazoles having an advantageous adhesion to the seeds, without being unacceptably viscous is provided by employing a polyether having a chain of ethylene oxide (EO) units and a hydrophobic portion, in the the ratio of the number of ethylene oxide (EO) units to the length of the hydrophobic portion of the polyether molecule is in a specific ratio. More particularly, the adhesion of 1-aryl pyrazoles to seeds is increased when the ratio of the number of ethylene oxide (EO) units to the length of the hydrophobic portion of the polyether molecule is above 0.5, more preferably in the range of 0.5 to 3.0.

[00028] Therefore, in a further aspect, the present invention provides an agrochemical composition comprising:

[00029] A) at least one agrochemical active ingredient of 1-aryl pyrazoles of formula (I)

[00030] In which

[00031] R1 represents a halogen atom or CN or a methyl group;

[00037] R8 represents alkyl or haloalkyl or a hydrogen atom;

[00043] X represents a trivalent nitrogen atom or a C-R12 radical, the other three valencies of the carbon atom forming part of the aromatic ring;

[00044] With the proviso that when R4 is methyl, then R3 is haloalkyl, R4 is NH2, Rn is Cl, R43 is CF3 and X is N; or R2 is 4,5-dicyanoimidazol-2-yl, R4 is Cl, R11 is Cl, R13 is CF3 and X is C-Cl; and

[00045] B) one or more adhesion promoters comprising a polyether having a chain of ethylene oxide (EO) units and a hydrophobic portion, in which the ratio of the number of ethylene oxide (EO) units to the length of the hydrophobic portion of the polyether molecule is at least 0.5.

[00046] In a further aspect, the present invention provides a method of treating seeds comprising applying to the seeds a composition as previously defined.

[00047] Still in a further aspect of the present invention, a method of controlling soil-borne pests at a site is provided comprising applying a composition as previously defined to seeds and sowing the seeds at the site.

[00048] Still in addition, a method is provided to protect seedlings emerging from a crop against one or more insect organisms in the soil environment, the method comprising applying to the crop seeds a composition as previously defined.

[00049] It has been found that compositions of the present invention exhibit excellent adhesion to the seeds being treated, in particular providing adhesion of the active 1-aryl pyrazole to the seeds. The use of the compositions in seed treatment results in the active ingredient remaining adhered to the seeds after the seeds have been sown, particularly in soils with a high water or moisture content and / or during heavy rain, such as in the rainy season. As a result, the active ingredient remains effective in protecting the seeds in such conditions. In addition, the high adherence of the compositions to the treated seeds significantly reduces the bleach of the active component from the seeds, in turn reducing potentially harmful effects on the surrounding areas or environment.

[00050] Treatment of seeds with a composition of the present invention results in improved growth of eventual plants, including earlier germination of the seeds and increase in the weight of shoots and roots of the growing planas.

[00051] The composition of the present invention is particularly useful in the treatment and protection of rice, corn, cotton, dry beans, soybeans and wheat seeds.

[00052] Still further, the present invention provides a seed treated with a composition as previously described. The seeds of this aspect of the invention reduce the exposure of operators and users of the seed product to the active ingredient, in turn increasing the safety of the materials.

[00054] Still further, the present invention provides the use as an adhesion promoter of a polyether comprising a hydrophobic moiety in combination with the ethylene oxide (EO) chain of units, in which the ratio of ethylene oxide units ( EO) for the length of the hydrophobic portion of the polyether molecule is at least 0.5.

[00075] In the agrochemical composition of the present invention used in seed treatment, the compound of formula (I) can be present in any amount suitable to provide a composition effective in protecting the seeds being treated. Preferably, the composition of formula (I) is present in the composition in an amount of 0.5 to 50% by weight, more preferably from 0.75 to 30%, even more preferably from 1 to 20% by weight.

[00076] The composition of the present invention further comprises an adhesion promoter, which is a compound that increases or intensifies the adhesion of the active ingredient to the seeds being treated. Adhesion promoters are selected from polymers or polyether copolymers.

[00077] Polymers or copolymers of polyethers used as adhesion promoters can be branched, in particular hyper-branched. The term hyper-branching is a reference to polymer molecules having a high degree of branching. Hyper-branching of the polyether molecules can be achieved in a known manner, for example, by cross-linking or grafting groups such as hydroxyl, anionic or lipophilic groups. Preferably, the polyether polymers or copolymers used as adhesion promoters do not contain substantially hyper-branching.

Suitable polyester compounds are those having 16 to 50 fractions of ethylene oxide (EO), more preferably 18 to 45 fractions of EO. In some embodiments of the invention, the polyether comprises 20 to 40 EO fractions, more preferably 20 to 35, especially 25 to 35 EO fractions.

Examples of such preferred polyethers include fatty alcohol polyethylene glycol, fatty acid reaction products with ethylene oxide, tristyryl polyether, tributyl phenol polyether, polyoxyethylene tristyryl phenol, polyoxypropylene-polyoxyethylene and octoxynol block copolymers.

[00080] In a second aspect of the invention, the polyether molecule present as an adhesion promoter comprises a hydrophobic moiety in combination with a chain of ethylene oxide (EO) units, wherein the ratio of ethylene oxide units ( EO) for the length of the hydrophobic portion of the polyether molecule is at least 0.5, more preferably at least 1.0, even more preferably at least 1.5. Preferred polyethers are those having the aforementioned ratio in the range of 0.5 to 3.0. Preferably, the aforementioned ratio is in the range of 0.7 to 2.5, even more preferably in the range of 1.0 to 2.0.

[00081] In this respect, the ratio of ethylene oxide (EO) units to the length of the hydrophobic portion of the polyether molecule is a reference to the ratio of the number of carbon atoms in the units. For example, a CiS-C18 fatty alcohol polyglycol ether having 25 ethylene oxide units has a ratio of ethylene oxide (EO) units to the hydrophobic portion of the molecule from 25/16 to 25/18, which is 1, 56 to 1.39.

[00082] The polyether molecule comprises a hydrophobic moiety. In this context, the "hydrophobic portion" refers to the hydrocarbon chain attached to the ethylene oxide chain. Such hydrocarbon chains can be saturated or unsaturated, optionally substituted with alkyl groups. The length of the hydrophobic portion of the polyether molecule is based on the total number of carbon atoms in the hydrocarbon chain. For example, an isotridecyl alcohol polyglycol ether with 10 units of ethylene oxide has a ratio of 10/13, which is 0.77. In addition, polyethers used in the present invention include polyethers covered at the end with an alkyl group. An example is CI2-C18 fatty alcohol butyl ethoxyl ether with 10 EO units, which has a ratio of EO units to hydrophobic portion of 10 / (12 + 4) to 10 / (18 + 4) which is 0.63 to 0 , 46.

[00083] Preferred polyethers are those in which the hydrophobic portion includes a fatty alcohol. Examples of such polyethers include polyethers of fatty alcohols, for example, polyethers of oleyl alcohol and stearyl alcohol. Other examples of suitable polyethers are those derived from fatty acids, for example, lauric acid, myristic acid and coconut fatty acid. Polyethers derived from block copolymers, such as polyoxypropylene-polyoxyethylene block copolymers can also be used.

[00084] In a particularly preferred embodiment, the composition of the present invention comprises as a adhesion promoter a polyether having a chain of ether-linked units comprising at least 16 fractions of ethylene oxide (EO), the molecule further comprising a hydrophobic moiety in combination with the ethylene oxide (EO) chain, where the ratio of ethylene oxide (EO) units to the length of the hydrophobic portion of the polyether molecule is at least 0.5, more preferably 0.5 to 3.0.

[00085] In the composition of the present invention, the weight ratio of the adhesion promoter to the weight of the agrochemical active ingredient can be in any suitable range to provide the necessary adhesion of the active ingredient to the seeds to be treated, without resulting in the composition having a excessive viscosity. Preferably, the ratio is in the range of 0.005 to 5, more preferably from 0.0075 to 3, even more preferably from 0.01 to 2.

[000110] In addition to treatment with the composition of the present invention, the seed can be treated with one or more other pesticides, for example, one or more fungicidally active agents, fertilizers and / or biocontrol agents.

[000111] Pesticides suitable for use in the composition of the present invention include those listed here and those listed in The Pesticide Manual, 9th Ed., Editor, Charles Worthing, published by the British Crop Protection Council and hereby incorporated by reference.

[000112] A fungicide can be applied to the seed before the coating layer of the composition described here. The application of a fungicide as a powder, paste or the like is a practice well known in the art. Suitable examples of fungicides include Captan (N- (trichloromethylthio) -cyclohex-4-ene-1,2-dicarboximide), Thiram (tetramethylthioperoxydicarbonic diamide), Metalaxyl, Fludioxonil (4- (2,2-difluoro-l, 3- benzodioxol-4-yl) -1H-pyrrole-3-carbonitrile), and Oxadixyl (N- (2,6-dimethyl phenyl) -2-methoxy-N- (2-oxo-3-oxazolidinyl) acetamide). A person skilled in the art will be aware of other beneficial fungicides suitable for combating harmful pathogens that are not only a problem for a specific location where the coated seed is to be grown, but also suitable for protecting seeds in storage before planting.

[000113] The amount of fungicidal composition to be added will vary according to such factors as the activity of the fungicidally active ingredient, but in general it can vary from approximately 0.001 to approximately 10% by weight of the seed and preferably from approximately 0.01 to 2 , 0%. However, for a specific situation the quantity may be greater or less.

[000114] Biocontrol agents suitable for use with the composition of the present invention are bacteria of the genera Rhizobium, Bacillus, Pseudomonas and Serratia, fungi of the genera Trichoderma, Glomus and Gliocladium and mycorrhizal fungi.

[000115] The composition of the present invention is applied to the seeds most preferably to form a coating on the seeds. Conventional coating means can be used to perform the coating. Various coating machines are known and available to a person skilled in the art. Three well-known techniques include the use of drum coaters, fluidized bed techniques and gushed beds. The seeds to be treated can be pre-sized before coating. After coating, the seeds are preferably dried and then optionally sized to transfer to a sizing machine. Suitable sizing machines that are known in the art are the common seed sizing machines in the industry.

[000116] The amount of the composition to be applied will vary depending on the size of the seed to be coated. The insecticide-active ingredient in the coating must not inhibit seed germination and must not be effective at least during that time in the life cycle of the target insect that causes damage to the crop. A person skilled in the art will recognize that this time will vary depending on the target insect, among other factors. In general, the coating will be effective for approximately 0 to 120 days after sowing. The coating of the present invention will contain an amount of insecticide that is insecticidally effective. An insecticide effective amount used here means that the amount of insecticide that will kill insect pests in the larvae or pupa growth stage will either consistently reduce or delay the amount of damage produced to the seeds or plants by insect pests.

[000117] Seeds treated with the composition of the present invention have the following advantages: they present less risk in relation to operators handling the seeds and reduced exposure, in particular to dust. Pesticides can be applied in a uniform manner and loss of pesticides during transport and handling is significantly reduced or avoided. Phytotoxicity to developing seeds and seedlings and therefore there is little or no adverse effect on germination, seedling emergence and seedling development. Additionally, the placement of pesticides, particularly insecticides, closer to the soil feed zone is possible with compositions of the present invention, which in turn can improve insect control. Unlike the adhesion agents generally used in seed treatments, seeds treated with the present invention show improved adhesion of the active ingredients to the seeds, particularly in soils of higher humidity and / or during the rainy season.

[000118] Specific modalities of the present are described below only as an example.

DETERMINATION OF MEMBERSHIP

[000119] The adhesion of the composition to seeds treated with the composition can be determined by the following procedure. Water spraying simulates the situation of a soil with high humidity or a rainy season.

[000120] Soak 1 kg of seeds in water for 48 hours and then drain. Take 100 g of these seeds.

[000121] Dilute the composition being tested with water to obtain a treatment solution containing 25 mg of the active agrochemical ingredient.

[000122] Apply the resulting treatment solution to 100 g of drained seeds by mixing the seeds with the treatment solution.

[000123] Spray the treated seeds with water according to the following steps:

[000124] Drain the treated seeds for 2 hours. Place 40 g of the treated seeds in a measuring cylinder with 250 ml of water. Close the cylinder with a stopper and rotate the cylinder about the horizontal axis five times. Rotating the cylinder means rotating the cylinder 180 ° down, then 180 ° up in the opposite direction. Dry the seeds at 30 ° C for 15 hours. The amount of the agrochemical active ingredient adhered to the seeds is determined by HPLC chromatography.

[000125] The level of adhesion after spraying is equal to the weight of the agrochemical active ingredient determined by the chromatography divided by the total weight of the active ingredient present in the treatment solution. The level of adhesion after spraying is expressed as a percentage by weight.
