Description

  TECHNICAL FIELD The present invention relates to a pesticide composition for water surface application, a solid pesticide package thereof, and a method for producing the same.

  As general agricultural chemical formulations, powders, granules, wettable powders, water solutions, flowables, liquids, emulsions and the like are known. Of these, spraying agents such as wettable powders, water solutions, and emulsions are mainly used in upland fields and non-agricultural fields. However, wettable powders and water solutions cause worker health problems due to dusting. There are problems of environmental impact, and emulsions have problems of environmental pollution due to solvents and emulsifiers and fire hazard due to organic solvents. In addition, many pesticide active ingredients are difficult to dissolve in water, and it is often difficult to formulate them into liquid formulations. For these reasons, the use of aqueous or oily suspension preparations (flowables) or dry flowables with less such problems has recently been increasing.

  On the other hand, examples of the water surface application agent for paddy fields include powders and granules, and conventionally granules have been mainly used. Granules are generally applied in an amount of 3 to 4 kg per 10 ares, but in recent years, demands for labor-saving spraying of agricultural chemicals have been increasing, and development of small-scale spraying agents for reducing the application rate of agricultural chemicals is required. On the other hand, if it is attempted to reduce the application amount of the granule, the content of the pesticide active ingredient in the granule will inevitably increase, and the number of particles per unit area will decrease. These are factors that directly affect the biological effects of pesticide active ingredients and phytotoxicity on crops, and it is required to treat pesticide formulations as uniformly as possible over the entire paddy field.

  However, the 1 kg granules developed in recent years require a certain amount of technology and experience in order to be evenly applied to flooded sewage fields, and it is not easy to achieve uniform application, and in some cases, Since a spraying device is required, it is not always satisfactory as a dosage form for labor saving.

  Therefore, in the field of water surface application agents in paddy fields, development of aqueous suspension preparations is often seen for the purpose of labor saving and efficiency improvement during spraying. Unlike an aqueous suspension formulation used in fields, non-agricultural lands, etc., this formulation does not require dilution, because it is dripped or poured directly from a container into a paddy field without diluting the formulation. In addition, since the treatment amount of the formulation is as small as 200 ml to 1 liter per 10 ares, it has a feature that it is light and easy to handle. Depending on the area of the field, it can be transferred from a ridge (so-called frame treatment) or when entering water. It is possible to perform a process of only irrigating from the water mouth (so-called water mouth treatment). Therefore, since the preparation can be processed with extremely labor-saving processing, the market is expanding rapidly after its release. However, since the aqueous suspension preparation is a preparation in which an agrochemical active ingredient is dispersed or emulsified in water, it has a problem that it is difficult to apply to an agrochemical active ingredient which is easily hydrolyzed.

  Also, in recent years, as a formulation in consideration of labor saving and environmental protection of pesticide spraying, a solid formulation such as tablet, pea-shaped formulation, and granular formulation, which is packaged in water-soluble paper such as water-soluble film, for paddy field dumping (pack or jumbo formulation). ) Is becoming more popular. Although such a formulation has the advantage of being able to easily treat pesticides for paddy fields, it does not undergo uniform treatment like the conventional treatment of granules and powders, and when these solid formulations are poured into water, the formulation becomes Settles on the soil surface. Here, since the sediment will cause the pesticidal active ingredient to be dispersed in the paddy water without foaming or foaming, the undissolved raw material particles will settle around the dropping point. Further, the dissolved pesticide active ingredient forms a high-concentration solution near the surface of the soil at the dropping point, so that it is easily adsorbed to the soil. Therefore, even if the water solubility of the pesticidal active ingredient of the paddy field throwing formulation prepared by packaging these solid formulations with a water-soluble paper such as a water-soluble film is considerably high, the pesticide active ingredient is present in the soil near the dropping point of the formulation. It has a drawback that it is adsorbed at a high concentration, and depending on field conditions, weather conditions, etc., it is likely to cause phytotoxicity due to non-uniformity of active ingredients of pesticides, uneven efficacy, and adverse effects on subsequent crops.

As such granules, many effervescent tablets have been developed in the past, but the use of non-effervescent granules has become the mainstream due to problems in terms of manufacturability and storage stability. For example, [1] (1) pesticide active ingredient, (2) water-floating particle nuclei containing one or more selected from burned vermiculite, expanded perlite, expanded shirasu and cork, and (3) acetylene alcohol and acetylene. A water-floating agricultural chemical solid agent containing one or more water surface extenders selected from diols and surfactants obtained by adding alkylene oxides to polyvinyl alcohol, its derivatives, or polyvinyl alcohol and its Agricultural formulation for throwing in paddy (Patent No. 2815535; Patent Document 1), in which the active ingredient is dispersed or dissolved in water, which is packaged in a film or sheet made of a derivative, [2] (1) Agrochemical active ingredient and (2) Pesticide granules or tablets in which a powder base having a specific gravity of 1 or less and (3) a surfactant having a large interfacial tension lowering ability are uniformly dispersed (JP-A-7-233002; Patent Document 2), [3] (1) (2) Pesticidally active substance and (3) substance capable of changing air-water interfacial tension on a grain nucleus having an apparent specific gravity of less than 1 and having a grain size in the range of about 300 μm to about 1,400 μm. (4) a pesticidal preparation for water surface application having good floating mobility, characterized by being carried and coated with an oily substance (JP-A-9-183701; Patent Document 3), [4] (1) one kind or (2) one or more surfactants selected from the group consisting of two or more agrochemical active ingredients, (2) α-olefin sulfonate, α-sulfo fatty acid salt and oleylmethyl tauride salt, and (3) apparent Water surface application having a specific gravity of less than 1 and containing a hollow mineral substance carrier, a plant carrier, a synthetic resin foam, or a molded grain nucleus containing one or more of these and imparting the property of floating in water. agrochemical composition (Japanese Patent No. 3535429; Patent Document _{4), [5] C 4} ~C 10 alkyl alcohol _C 2 -C ₄ alkylene oxide adduct thereof and the one consisting of derivatives or two or more of the water surface extender agent And a water-floating pesticide solid preparation containing a pesticide active ingredient (Japanese Patent Laid-Open No. 2000-351701; Patent Document 5) and a granular carrier containing a water-floating grain core, a water surface spreader, an agrochemical active ingredient and a surfactant. A pesticide solid formulation for paddy fields, which is supported and formulated, wherein the water surface spreader has a specific gravity of 1.15 or less and a water solubility of 0.01 to 10%. 2-phenoxyethanol, 1-phenoxy- Selected from 2-propanol, 3-methoxy-3-methylbutylacetate and 3,5,5-trimethyl-1-hexanol At least one organic solvent, wherein the surfactant is at least one selected from alkylallyl sulfonate inorganic phosphate, isobutylene-maleic acid copolymer, polycarboxylic acid salt and polyacrylic acid salt. Agricultural solid agricultural chemicals for paddy fields (Patent No. 4280017; Patent Document 6) are known as a technique for improving the spreadability of water surface floating granules.

Patent No. 2815535 JP-A-7-233002 JP-A-9-183701 Patent No. 3535429 JP-A-2000-351701 Patent No. 4280017

  However, these existing methods have not always been able to obtain sufficient water surface spreadability in practical situations. In other words, algae, rice husks and other suspended solids often cover the surface of the paddy field in such practical situations.In such a case, even if the existing water surface application agent is treated, Since the substance inhibits the floating spread of the agricultural chemical active ingredient, even if the water surface application agent is treated, the agricultural chemical active ingredient cannot be spread uniformly. Furthermore, even in paddy fields that seem to have no floating matter at first glance, there may be some floating matter that cannot be visually confirmed from the shore. In such a case, existing water surface application Even if the agent is treated, it cannot be expected that the active ingredient of the pesticide will be sufficiently spread in suspension. In particular, at the time of treatment of so-called mid-term agents and imotic agents, in addition to the increase of suspended solids on the water surface, the growth of rice and weeds also inhibits the diffusion of pesticide active ingredients, so that it is practical. In order to obtain the effect, it is necessary to further enhance the drug diffusion performance.

  The problem of the present invention is that in the paddy field, there is a suspended matter that inhibits the floating and spreading of the active ingredient of pesticides, and even under the condition that rice and weeds grow, the pesticide formulation can spread and spread well on the water surface. Designing a pesticide formulation, but a technique sufficient to simultaneously solve several problems including this problem has not been known so far. That is, the pesticide formulation 1) does not require special equipment for spraying, 2) is labor-saving, 3) is safe for the sprayer and the environment, and 4) has a fixed form such as a plastic container. Since the container is not used, it is easy to treat the container. 5) There is no risk of drug damage due to segregation of the active ingredient of agricultural chemicals or uneven distribution. 6) Rice or weeds even if there are some obstacles. It was demanded that the pesticide formulation have excellent water surface floating spreadability, and 7) that it was stable over time, and its treatment method even when the plant grew.

  As a result of intensive studies aimed at developing an agricultural chemical formulation satisfying the above conditions and a treatment method thereof, the present inventors have found that a glycol ether solvent as a liquid extender component and specific particles having an apparent specific gravity of less than 1. A novel pesticide composition comprising a coating layer containing a core, one or more solid surfactants, the pesticide composition being packed in a suitable container equipped with a transfer port, The pesticide composition is effective at the point of dropping by direct transfer treatment or by subdividing the pesticide composition into a film that disperses or dissolves in water into a film and throws it into paddy fields.

  The following is a comparison between the water-applied pesticide composition of the present invention and the above-mentioned prior art.

  That is, comparing the surface-applied pesticide composition of the present invention with the water-floating pesticide solid agent of Patent Document 1, both have common points of the pesticide active ingredient and water-floating particle nuclei, but the water surface of the present invention is the same. Whereas the applied agricultural chemical composition contains a glycol ether solvent and a solid surfactant in the coating layer, the water-floating agricultural chemical solid agent of Patent Document 1 contains acetylene alcohol, acetylene diol, and alkylene oxide. The two are different in that they contain one or more water surface extenders selected from the added surfactants.

  The agrochemical composition for water surface application of the present invention shows that, when comparing the agrochemical granules or tablets of Patent Document 2, both are an agrochemical active ingredient and a water surface floating granule (in Patent Document 2, a powder base having a specific gravity of 1 or less). However, while the water-applied pesticide composition of the present invention contains a glycol ether solvent and a solid surfactant in the coating layer, the pesticide granules of Patent Document 2 or The two are different in that the tablet has a surfactant having a large ability to reduce the interfacial tension uniformly dispersed.

  The surface-applied agrochemical composition of the present invention is compared with the surface-applied agrochemical preparation of Patent Document 3, and both are an agrochemical active ingredient, water-floating particle nuclei (in Patent Document 3, apparent specific gravity is less than 1 and about 300 μm). To about 1,400 μm, and in the present invention, 90% or more of the grain nuclei are generally classified into the 0.500 mm to 4.760 mm range.) The common point is that the substance capable of changing the air-water interfacial tension is supported and coated with an oily substance, but the agrochemical composition for water surface application of the present invention contains a glycol ether solvent. On the other hand, the two are different in that the agricultural chemical preparation for surface application of Patent Document 3 does not contain a glycol ether solvent.

  When comparing the surface-applied agrochemical composition of the present invention with the surface-applied agrochemical composition of Patent Document 4, both of them show that the agrochemical active ingredient, water-floating particle nuclei, and solid surfactant (in Patent Document 4, α- The water surface of the present invention is the same in that the olefin sulfonate, the α-sulfo fatty acid salt, and the oleylmethyl tauride salt are used as one or two or more kinds of surfactants. The pesticidal composition for application contains a glycol ether-based solvent, whereas the pesticide formulation for water surface application of Patent Document 4 does not contain a glycol ether-based solvent.

The surface-applied pesticide composition of the present invention is compared with the surface-applied pesticide composition of Patent Document 5, and both of them show that the pesticide active ingredient, the water-floating particle nucleus, and the glycol ether solvent (in Patent Document 5, C ₄ To C ₁₀ alkyl alcohol and C _{2 to} C ₄ alkylene oxide adducts and derivatives thereof) are contained in common, but the water surface application agrochemical composition of the present invention comprises a solid surfactant in the coating layer. On the other hand, the water-applied agrochemical formulation of Patent Document 5 differs from the above in that the surfactant is contained only inside the grain nuclei and is not contained in the coating layer.

  The surface-applied agrochemical composition of the present invention has a common point that, when comparing the surface-applied agrochemical composition of Patent Document 6, both contain an agrochemical active ingredient, a water-floating particle nucleus, and a polycarboxylic acid salt as a surfactant. However, the pesticidal composition for water surface application of the present invention is characterized in that the particle surface is coated with a solid surfactant, that is, the coating layer contains a solid surfactant. On the other hand, in the case of the pesticide formulation for surface application of Patent Document 6, referring to the production of the pesticide solid formulation for paddy fields and the description of Examples 1 to 12 described in the paragraph [0034] of the specification, any of the examples The formulation (1) is also characterized in that it is obtained by performing a granulation step using water and further subjecting the obtained granulated product to a drying step. Therefore, while the surface-applied agrochemical composition of the present invention has a coating layer containing a solid surfactant, the surface-applied agrochemical formulation of Patent Document 6 is kneaded and granulated. Is different. In the water-applied agrochemical composition of the present invention, the active ingredient can be rapidly spread together with the surfactant from the coating layer of the exterior part, which is a structural feature, while the water-applied agrochemical composition of Patent Document 6, Since the surfactant is gradually eluted (or released) from the granules, the active ingredient gradually diffuses. Furthermore, since the pesticide formulation for water surface application of Patent Document 6 is kneaded and granulated, the particle size is large, and in the manufacturing process thereof, a hydro-kneading process, a granulation process, and a drying process are performed, so that a particle core is formed. Compared with the water-applied pesticide composition of the present invention, which is capable of directly treating a solid surfactant and forming a coating layer without going through a hydro-kneading step, a granulating step, and a drying step, handling and production efficiency in production Is disadvantageous in that.

  According to the present invention, when the surface-applied pesticide composition is applied to a submerged paddy field, by the spreading power of the glycol ether solvent and the solid surfactant contained in the coating layer, the surface-applied pesticide composition Prevents the active ingredient from settling at the dropping point and self-diffuses in various directions on the surface of the water, and the active ingredient of agricultural chemicals can be rapidly dispersed and evenly dissolved in the surface water. Further, the water-applied pesticide composition of the present invention, because the release rate of the pesticide active ingredient into water is fast, even if the granules are blown by the residual wind on the water surface, the pesticide active ingredient is already blown before being blown. Since it is released from the grain nuclei, it has a preferable feature in practical use that it does not greatly affect the manifestation of its action and effect.

It is a figure which shows a suspension tester.

  When a liquid pesticide active ingredient is used, a carrier having an apparent specific gravity of less than 1 or a particle nucleus or an oil-absorbing ability is impregnated with the liquid pesticide active ingredient, a glycol ether solvent and an appropriate oily substance, and thereafter, Granules are prepared in the same manner as solid pesticide active ingredients. After that, like the solid pesticide component, a solid surfactant is coated to produce a granule.

  When the pesticidal composition for water surface application of the present invention is a granule, the granule has a particle size that is less likely to sink in water if the particle size is larger than 0.5 mm, and conversely if the particle size is smaller than 5 mm. It is more difficult to be blown away by, and it becomes easier to pass through between grown rice, so that it is less likely to cause segregation of the active ingredient. Therefore, it is preferable that 90% or more of the granules have a normal particle size of 0.500 mm to 4.760 mm.

  The thus obtained surface-applied pesticide composition of the present invention is a box, bottle, bag or the like with a suitable transfer port, which is directly transferred into the paddy field or packaged in a water-soluble film or sheet. As a package, it can be thrown in directly from a ridge. Since the pesticidal composition for surface application of the present invention is designed to release the pesticide active ingredient while spreading on the surface of the water, it does not need to enter the paddy field and be evenly sprayed like a general granule. Therefore, if the paddy fields are appropriately treated, a sufficient biological effect can be obtained. The water-soluble film or sheet used in the present invention is a film or sheet having a property of being dissolved or dispersed in water, and its constituent material is, for example, polyvinyl alcohol or a derivative thereof, polyvinyl alcohol. Examples of the fibers include fibers (for example, non-woven fabric), pullulan film, carboxymethylcellulose sodium salt and cellulose, polyethylene oxide and its derivatives, and particularly polyvinyl alcohol or its derivatives. The film (hereinafter abbreviated as PVA film) itself has the property of easily dispersing or dissolving in water and spreading the pesticidal composition for water surface application of the present invention on the water surface.

  The PVA film used in the present invention is, for example, a film obtained by filming polyvinyl alcohol having a polymerization degree of 1000 to 2000 and a saponification degree of 85 to 95% together with a small amount of a plasticizer, a stabilizer, and the like. It also includes a film containing a small amount of a copolymer such as a carboxylic acid in the polymer. The thickness of the PVA film is usually 25 to 70 μm, preferably 30 to 50 μm, as a result of considering the film strength and the dissolution time. Further, it is convenient that the end portion of the PVA film can be heat-sealed.

  When packaging in the above PVA film, the weight of one package is usually 10 to 200 g, preferably 20 to 60 g, considering the ease of throwing, and the number of packages is usually 10. A sufficient biological effect can be exhibited by dropping 2 to 40 pieces per are, and preferably 4 to 20 pieces.

It is not something that will be done.

  The "spreadability index" in the present specification is a numerical value of spreadability of a pesticide composition for water surface application on the water surface in the range of 0 to 15 points (maximum 15 points). The spreadability is good, preferably 7 or more, more preferably 9 or more, and even more preferably 11 or more. The test method of water surface spreadability is as follows.

  25 L of tap water is put into a tou of 4 m in length and 14 cm in width, and 2 g of rice husk powder is treated so as to be uniform on the water surface, assuming obstacles (floats) on the surface water of the rice field. After still standing, 300 mg of the surface-applied pesticide composition was put into a point 10 cm from one end of the tou, and the water-applied pesticide composition after the introduction was reached 1.5 m from the introduction point, the longest arrival from the introduction point. The distance and the state of spread after 5 minutes from the visual inspection are visually inspected, and judgment is made according to the evaluation criteria shown in Table 1 below, and the spread indexes of the respective items are summed up to obtain respective spread indexes.

  The "suspension degree" in the present specification is a measure of the amount of sedimentation in water when the surface-applied pesticide composition is treated on the water surface, and the amount of sedimentation at the dropping point where the drug is applied to the paddy field can be simply calculated. It is a method of measuring.
