Description

  The present invention relates to an agricultural and horticulturally useful granular agricultural chemical composition containing 3- (3,4-dichloroisothiazol-5-ylmethoxy) -1,2-benzothiazole-1,1-dioxide and a method for producing the same. In particular, the present invention relates to an agricultural and horticulturally useful granular agricultural chemical composition having excellent storage stability and a method for producing the same.

  At present, dosage forms such as powders, granules, wettable powders, granular wettable powders, flowables, liquids, and emulsions are known as forms of agricultural chemical formulations. Among them, the granule is a dosage form in which an agrochemical formulation is directly sprayed, and is used in aspects such as water surface application in a paddy field, breeding box treatment, and soil mixing in a field. Pesticide treatment work is simple, does not require water for spraying, and there is no fear of scattering of agricultural chemical active ingredients due to powdering, so it has become the mainstream dosage form in Japan.

  A general aspect of a granular agrochemical composition used as a granule is to mix a pesticide active ingredient and a solid carrier such as clay or calcium carbonate, add water to the mixture obtained above and knead to obtain a predetermined pore size. It is a granular material produced by extruding and granulating using a die having it and then drying. In such granular materials, the contact between the pesticidal active ingredient and the moisture in the environment is limited, so the elution behavior of the pesticidal active ingredient tends to be more slowly released, and the pesticidal activity that requires sustained effect is required. Suitable for ingredients. Moreover, as another aspect, there is also a granular agricultural chemical composition which is a granular material obtained by coating an agricultural chemical active ingredient with a binder on the surface layer of a grain core having an appropriate particle size obtained by crushing or granulating mineral substances. Are known. In such a granular material, since the pesticidal active ingredient comes into direct contact with moisture in the environment, the pesticidal active ingredient can be eluted more quickly, and it is suitable for an pesticidal active ingredient that requires quick action. Furthermore, there may be an embodiment of the latter granular material in which the former granular material is used as a grain nucleus. A person skilled in the art can select and use a suitable granule mode according to the elution pattern required for the pesticidal active ingredient to be blended.

  On the other hand, agricultural and horticultural control targets for agricultural chemical formulations include pests and weeds in addition to diseases, and it is necessary to deal with all of them, but active ingredients for disease control are specialized in disease control and are usually pests. And weeds do not show sufficient control activity. Similarly, pest control active ingredients and weed control active ingredients are specialized for pest control and weed control, respectively. Therefore, in modern agriculture, management of agricultural land and the like is carried out by using a disease control active ingredient for pest control, a pest control active ingredient for pest control, and a weed control active ingredient for weed control. Yes. In addition, each disease control active ingredient has an effective disease and a disease that is not good. In order to cope with a large number of control targets generated in agricultural land and the like, a large number of disease control active ingredients having different spectra have been developed. The same applies to pest control active ingredients and weed control active ingredients. From such a background, in recent years, a plurality of granules are used by mixing at the time of use, or a mixed pesticide granule in which a plurality of agrochemical active ingredients are blended with a single pesticide granule is also used.

  3- (3,4-dichloroisothiazol-5-ylmethoxy) -1,2-benzothiazole-1,1-dioxide (hereinafter, the same substance may be referred to as “compound A” in the present specification) ) Is a known plant disease control active ingredient for agricultural and horticultural use, and Patent Document 1 shows a remarkable effect on plant diseases such as rice blast, wheat blight, cucumber downy mildew, cucumber anthracnose, etc. It is disclosed. Since this compound A is intended to control and prevent plant diseases over a long period of time required for the growth of crops and the like, the compound A is formulated as a granule as an embodiment. It is preferable to use a granulated product kneaded in the grains together with a solid carrier or the like.

  However, since compound A is a chemically unstable compound and its decomposition may be unnecessarily promoted in the presence of various chemical substances, the storage stability of compound A in granular agrochemical compositions Improvement was desired. In particular, in a mixed agrochemical granule in which Compound A and other agrochemical active ingredients are used in combination, since a plurality of chemical substances coexist intentionally, decomposition of Compound A may be further promoted, which may be a more disadvantageous obstacle. Therefore, it has been difficult to develop a granular agricultural chemical composition having excellent storage stability of Compound A without being affected by these chemical substances.

International Publication No. 2007/129454

  According to the present invention, an agricultural and horticulturally useful granular agricultural chemical composition having excellent storage stability of 3- (3,4-dichloroisothiazol-5-ylmethoxy) -1,2-benzothiazole-1,1-dioxide Products and methods of manufacturing the same can be provided.

  The granular agrochemical composition of the present invention is a granular agrochemical composition having a grain core and an outer layer portion covering the grain core, wherein the grain core is 3- (3,4-dichloroisothiazol-5-ylmethoxy). It contains -1,2-benzothiazole-1,1-dioxide, and the outer layer portion contains a liquid sugar that is a saccharide that does not crystallize at room temperature. The granular agrochemical composition of the present invention suppresses the decomposition of the compound and is excellent in storage stability due to the presence of the outer layer portion containing liquid sugar. Moreover, the granular agrochemical composition of this invention can be used, without impairing the storage stability of the said compound A, also when using as a mixed agrochemical granule with another agrochemical active ingredient. In the conventional granular agrochemical composition, even when other pesticidal active ingredients are coated on the grain nuclei containing the compound A using a conventional binder, the contact opportunity between the compound A and the other pesticidal active ingredients is relatively small. Nevertheless, the storage stability of Compound A was greatly deteriorated.

  In the granular agrochemical composition of the present invention, it is important that compound A is contained in the nucleus. Although content of compound A is not specifically limited, 0.1-8 mass% is preferable with respect to the whole granular agrochemical composition, More preferably, it is 0.2-4 mass%.

  The grain nuclei containing compound A are, for example, compound A as a mixture with a finely divided solid carrier, and the mixture is stirred and granulated, tumbling granulated, extruded granulated, crushed granulated, fluidized bed granulated It is produced by making a granulated product by a known granulation method such as a granulation method, a compression granulation method, or a vacuum drying granulation method.

  Specific examples of the finely divided solid carrier include bentonite, clay, kaolin, sericite, talc, acid clay, pumice, zeolite, vermiculite, perlite, calcium carbonate, silica sand and the like. These may be arbitrarily used alone or in combination of two or more.

  The method for granulating the grain nuclei is not particularly limited, but when carrying the pesticidal active ingredient in the outer layer of the grain nuclei, the grain nuclei surface area that determines the amount of the pesticidal active ingredient that can be carried in each grain nucleus. A granulation method that can obtain a granulated product with a small yield, that is, a granulated product having a narrow particle size distribution, is preferable. An extrusion granulation method is particularly preferable as a method suitable for this purpose, and a granular material obtained by the extrusion granulation method is preferably used as a grain nucleus.

  The shape of the particle nucleus is not particularly limited, but a granular material having an appropriate particle size as an agrochemical granule is preferable, and more specifically, a substantially spherical material having a diameter of 0.1 to 30 mm, or a volume sphere equivalent diameter of 0.1 to A 30 mm indefinite shape, a substantially cylindrical shape having a diameter of 0.1 to 5 mm, a length of 1 to 30 mm, and an aspect ratio (length / diameter) of 1 to 10 can be preferably used. Among these, a substantially cylindrical material having a diameter of 0.3 to 1.7 mm, a length of 0.3 to 10.2 mm, and an aspect ratio of 1 to 6 is preferable, and a diameter of 0.5 to 1.5 mm and a length of 0.5 to 7 are preferable. More preferred is a substantially cylindrical object having a diameter of 0.5 mm and an aspect ratio of 1 to 5, and a substantially cylindrical object having a diameter of 0.8 to 1.2 mm, a length of 0.8 to 4.8 mm and an aspect ratio of 1 to 4 is even more preferable.

  If desired, the grain nuclei may contain auxiliary components such as surfactants, binders, lubricants, and colorants. Furthermore, in the granular agrochemical composition of the present invention, as long as it does not impair the stability of Compound A, it is possible to control the dissolution of a safener, waxes, resins, hydrophobic substances, etc. An agent may be included.

  Examples of the surfactant include alkyl sulfate esters, aryl sulfonates, polyoxyethylene glycol ethers, polyhydric alcohol esters, dialkyl sulfosuccinates, polycarboxylic acids, polyoxyethylene nonylphenyl ether, sodium lignin sulfonate. Etc. These may be arbitrarily used alone or in combination of two or more.

  Examples of the binder include starch, alginic acid, glycerin, polyvinyl pyrrolidone, polyurethane, polyethylene glycol, polypropylene glycol, polybutene, polyvinyl alcohol, gum arabic, liquid paraffin, ethyl cellulose, and polyvinyl acetate. These may be arbitrarily used alone or in combination of two or more.

  Examples of the lubricant include calcium stearate, talc, and silica. These may be arbitrarily used alone or in combination of two or more.

  Examples of the colorant include dyes and pigments. These may be arbitrarily used alone or in combination of two or more.

  Examples of the safener include benoxacor, furilazole, dichlormid, dicyclonone, DKA-24 (N1, N2-diallyl-N2-dichloroacetylglycinamide), AD-67 (4). -Dichloroacetyl-1-oxa-4-azaspiro [4.5] decane), PPG-1292 (2,2-dichloro-N- (1,3-dioxan-2-ylmethyl) -N- (2-propenyl) Acetamide), R-29148 (3-dichloroacetyl-2,2,5-trimethyl-1,3-oxazolidine), croquint set-mexyl, naphthalic anhydride (1,8-Naphthalic Anhydri) e), mefenpyr-diethyl (mefenpyr-diethyl), mefenpyr (mefenpyr), mefenpyr-ethyl (mefenpyr-ethyl), fenchlorazole-O-ethyl, fenchlorim (fenol91), MG-1 -Dichloromethyl-2-methyl-1,3-dioxane), ciomethrinil, flurazole, fluxofenim, isoxadifen, isoxadifen-ethyl, MON4660 code Oxabetrinil, cyprosulfamide (cyprosul) famide), lower alkyl-substituted benzoic acid, TI-35 (code number) or N- (2-methoxybenzoyl) -4-[(methylaminocarbonyl) amino] benzenesulfonamide (chemical name, CAS registry number: 129531-12) -0). These can be used alone or in combination of two or more.

  In the granular agrochemical composition of the present invention, it is also important that the outer layer portion covering the above-described grain nuclei containing Compound A contains liquid sugar, which is a saccharide that does not crystallize at room temperature. Here, liquid sugar is generally called molasses. As the type of liquid sugar, sugarcane molasses, sugar beet molasses, refined molasses molasses, ice molasses and invert sugar containing reducing sugar such as sucrose, which are hydrolyzed into glucose and fructose, are produced as sugar types. Examples include those containing invert sugar together with non-reducing sugars such as sugar and sucrose. Invert sugar containing reducing sugar, that is, invertible liquid sugar containing reducing sugar is preferable. Among the inversion-type liquid sugars, those containing 20% or more of reducing sugar are preferable, more preferably those containing 40% or more of reducing sugar, and containing about 50% of reducing sugar, specifically 45 to 54%. Liquid sugar is particularly preferred.

  The content of the liquid sugar is not particularly limited and may depend on the amount of the pesticidal active ingredient to be carried on the grain core, but is preferably 0.5 to 5% by mass with respect to the entire granular pesticidal composition, Preferably it is 0.8-2 mass%. If the content of the liquid sugar is insufficient, the storage stability of Compound A may be impaired, and when used as a mixed agricultural chemical granule, there is a risk that the function of supporting the agricultural chemical active ingredient on the outer part of the grain core will be insufficient. On the other hand, if the content of liquid sugar is excessive, the granular agrochemical composition may be consolidated.

  In the granular agrochemical composition of the present invention, the method for forming the outer layer portion containing liquid sugar is not particularly limited, but typically, the grain core is first mixed using a normal mixer such as a concrete mixer or a Nauta mixer. On the other hand, there is a method in which a liquid material containing liquid sugar is added thereto to coat the surface layer of the grain nuclei. When the granular agrochemical composition of the present invention is used as a mixed agrochemical granule, the agrochemical active ingredient is then added and supported on the outer part of the grain core.

  By the way, since the liquid sugar is usually a honey-like viscous liquid at room temperature, it may be difficult in the step of coating the liquid layer containing the liquid sugar on the surface layer of the grain nucleus. Means for solving this problem include a method of heating the liquid material to reduce the viscosity of the liquid sugar, a method of adding a small amount of a solvent such as water to the liquid sugar, and a method of reducing the viscosity of the liquid sugar. be able to. When water is added to the liquid sugar to obtain a liquid material, the amount of water added is not particularly limited, but it is appropriate that the amount be up to about 30% by mass with respect to the total amount of the liquid material. If the liquid composition is excessive in water, that is, a dilute liquid composition, it is necessary to add a large amount of liquid material in order to coat the grain nuclei with an effective amount of liquid sugar, and the grain nuclei wetted by excess water will aggregate. Therefore, when the granular agricultural chemical composition of the present invention is used as a mixed agricultural chemical granule, the agricultural chemical active ingredient is supported on the outer layer portion, which may hinder the process of supporting the agricultural chemical active ingredient.

  In the granular agrochemical composition of the present invention, an agrochemical active ingredient can be further contained on the outer layer portion. Only one kind of agrochemical active ingredient can be carried on the outer layer portion, or two or more kinds can be carried simultaneously. The agrochemical active ingredient can be carried on the outer layer part of the grain nucleus by the adhesive force of the liquid sugar.

  When the pesticidal active ingredient to be carried on the outer layer part is solid at room temperature, it is desirable to pulverize to a particle size of usually 50 μm or less, preferably 10 μm or less and use it as a powder. In addition, this powder includes grinding aids such as silica, diatomaceous earth and silica sand, surfactants such as lignin sulfonate, aryl sulfonate and alkyl sulfate, solid carriers such as bentonite, clay and calcium carbonate, alkali Adjuvants such as stabilizers such as metal salts, alkaline earth metal salts, epoxidized oils and fats, and safeners exemplified above can be blended.

  As a means for finely pulverizing the agrochemical active ingredient to be carried on the outer layer part, a known pulverizer can be arbitrarily used, and specifically, an impact pulverizer, an airflow pulverizer, a wet pulverizer, or the like is used. However, it is not particularly limited. In the fine pulverization, it may be pulverized only with an agrochemical active ingredient, or may be mixed with the auxiliary agent in advance and co-ground if desired.

  When the pesticidal active ingredient to be carried on the outer layer part is liquid at normal temperature, it may be carried on the outer layer part as it is in the liquid state, or in advance on oil-absorbing fine powders such as silica, silicate, wood powder, microcrystalline cellulose, etc. It can be adsorbed to prepare a powder and can be handled in the same manner as the agrochemical active ingredient that is solid at room temperature.

  The content of the pesticidal active ingredient that can be carried on the outer layer is also not limited, but when there are two or more pesticidal active ingredients relative to the whole granular pesticide composition, the total is usually 0. 0.05 to 5% by mass, preferably 0.1 to 4% by mass, and more preferably 0.5 to 3% by mass.

  In addition, as long as the active ingredient of the agrochemical is not impaired in stability of the compound A, one or more kinds can be blended in the grain nucleus, but in general, the agrochemical active ingredient contained in the grain nucleus It is presumed that the elution rate of is relatively slow. When it is desired that the granular agrochemical composition of the present invention contains an agrochemical active ingredient that is expected to exhibit rapid drug efficacy, it is reasonable to select a design that is supported on the outer layer of the grain core.

  In the granular pesticidal composition of the present invention, examples of the pesticidal active ingredient that can be contained in the grain nuclei or carried on the outer layer can include those listed below, but are not particularly limited.

  The method for producing a granular agrochemical composition of the present invention comprises a step of producing a grain nucleus containing 3- (3,4-dichloroisothiazol-5-ylmethoxy) -1,2-benzothiazole-1,1-dioxide, And the surface of the grain nucleus obtained at the said process is coat | covered with the liquid substance containing the liquid sugar which is saccharides which do not crystallize at normal temperature, and it has the process of forming an outer layer part on the surface of the said grain nucleus. The manufacturing method of the granular agrochemical composition of this invention may have the process of carrying | supporting an agrochemical active ingredient on the said outer-layer part further if desired after the process of forming the said outer-layer part.

  In the granular agrochemical composition of the present invention, the step of producing the grain nuclei containing the compound A includes, for example, compound A as a mixture with a finely divided solid carrier, and the mixture is stirred and granulated, tumbling granulation The granulation is performed by a known granulation method such as an extrusion granulation method, a crushing granulation method, a fluidized bed granulation method, a compression granulation method, or a vacuum drying granulation method.

  In the step of coating the surface of the grain nuclei obtained in the above step with a liquid material containing liquid sugar and forming the outer layer portion on the surface of the grain nuclei, typically, the grain nuclei are first made into a concrete mixer, Nauta. While mixing using a normal mixer such as a mixer, a granular material containing liquid sugar is added thereto to coat the surface layer of the grain core, thereby forming the outer layer portion. If it is difficult to cover the surface layer of the grain core by adding granular material containing liquid sugar, warm the liquid material in advance or add a small amount of solvent such as water to the liquid sugar to increase the viscosity of the liquid material. You may throw in after reducing.

  Next, in the step of supporting the pesticidal active ingredient to be supported on the outer layer part in the outer layer part of the grain core, the pesticidal active ingredient may be added to the outer layer part of the grain nucleus obtained in the step and supported on the outer layer part. . The pesticidal active ingredient to be carried on the outer layer portion may be used as it is, but it is usually desirable to pulverize it to a particle size of usually 50 μm or less, preferably 10 μm or less. As a means for fine pulverization, a known pulverizer can be arbitrarily used. Specifically, an impact pulverizer, an airflow pulverizer, or the like can be used, but it is not particularly limited. In the fine pulverization, the pesticidal active ingredient to be carried on the outer layer portion may be pulverized alone, or may be previously mixed with the auxiliary agent and co-ground if desired. Furthermore, when the pesticidal active ingredient is a liquid, it may be preliminarily adsorbed on the oil-absorbing fine powder and prepared in a powder form.

  The granular pesticidal composition of the present invention can be applied to all scenes in pesticide application, but is particularly effective in the so-called sowing and seedling season when it is applied at the stage of seed germination / rooting or seedling growth. For example, the period from the germination period to the time immediately before transplanting corresponds to the sowing and seedling growing season when mixing seedling soil in paddy rice box seedling, before sowing or after covering. Furthermore, transplantation simultaneous application has also been developed in recent years, and application to this field is also possible. Similarly, in cell tray raising seedlings such as vegetables, it can be applied from the time of mixing seedling culture soil to the time of transplantation, and particularly preferred are application at the time of sowing and germination, and planting at the time of transplantation. In addition, although cultivation at the sowing and seedling raising stage is usually carried out using seedling cultivation soil, it can also be applied to cultivation other than cultivation soil such as a seedling mat or sheet.

  As an application method, it can be applied by the same method as ordinary agrochemical granule, for example, direct granulation by hand, human-powered granulator, electric granulator, back type power granulator Examples include a traveling power granulator, a tractor-equipped granulator, a rice transplanter-equipped granulator, a side-line application medicine, an unmanned helicopter and the like. For paddy rice seedling box application, scoop up the granular pesticide composition with a measuring cup that can measure a predetermined amount, sprinkle it on the seedling box, put it in a special seedling box spraying container, and spray the seedling box, granular pesticide A method of directly spraying the seedling box from the outlet or hole provided on the packaging container of the composition, a method of spraying a large number of seedling boxes arranged widely using a power-type granulator, dedicated for sowing work The method of granulating into a seedling box with the apparatus of this, the method of mix | blending with seedling soil, etc. are illustrated.

  In order to carry out the above spraying properly, the physical properties of the granular agrochemical composition of the present invention are preferably within a certain range for various items. For example, the apparent specific gravity is preferably 0.3 to 2, more preferably 0.5 to 1.5 in the official agricultural chemical inspection method. The hardness of the grains is preferably 20 or less, more preferably 10 or less in the whole agricultural ball mill method. It is preferable that the particle size is 90% by mass or more of the whole granular composition that passes through a sieve having an opening of 1700 μm and does not pass through a sieve having an opening of 300 μm.

  Further, in the granular agrochemical composition, when the shape of the grain nucleus is substantially cylindrical, the diameter of the cross-sectional circle is usually 0.3 to 1.7 mm, preferably 0.5 to 1.5 mm, more preferably 0.8. 8 to 1.2 mm. The grain length corresponding to the height of the cylinder is preferably 0.5 to 6 times the circular diameter of the cross section. However, when spraying using a dedicated device at the time of sowing, for example, a seedling box-applied drug spraying device (beauty Good, model KS-25: Roller-type granulator), seedling box medicine hopper (Suzutec, model SDP-33S, SDP-103S: Roller-type granulator), pot seedling box medicine device (Minoru Industry Co., Ltd.) Manufactured, type MPA-21: roller type granulator), particles having a grain length of 2.5 times or more with respect to the cross-sectional circle diameter should be 50% by mass or less of the whole granular composition. Is more preferable, and 40% by mass or less is more preferable.

In addition, the application amount at the time of applying the granular agrochemical composition of the present invention is 0.1-20 kg per 10 ares, preferably 0.2-5 kg in the case of paddy fields and upland fields. It is 10 to 200 g, preferably 10 to 100 g per box (usually 0.16 m ² ). Moreover, when applying to a cell tray, the application amount of about 30g per cell tray (128 holes) may be sufficient.

  Specific examples of the present invention will be described below, but the present invention is not limited to these examples. In the following Examples and Comparative Examples, “part” represents “part by mass” and “%” represents “% by mass”. The “minor axis” refers to the cross-sectional circle diameter of the substantially cylindrical granulated product, and the “aspect ratio” refers to the quotient obtained by dividing the grain length of the approximately cylindrical granulated product by the minor axis.
