Therefore, rainwater or the like passes through the gap 9 and is absorbed by the ground 1. However, when passing, the active ingredient can be supplied to the ground 1 by controlling the elution amount of boron or the like.

  The water-permeable three-dimensional structure 6 of the present invention can be easily constructed on the ground such as cemeteries, cemeteries, parks, median strips (around planting), garden approaches, dog-running, under steel towers, under elevated bridges, intersections, and roadside belts. Since the herbicidal active ingredient is properly released from the hardly soluble aluminum compound granules and the hardly soluble boron compound granules, weed growth can be prevented and moss and mold are also prevented. It is possible to achieve excellent effects such as excellent sustainability of the effect and environmental friendliness.

The shape, dimensions, etc. of the water-permeable three-dimensional structure 6 of the present invention are not particularly limited.
In the above description, the shape of the water-permeable three-dimensional structure 6 of the present invention is a flat film or sheet. However, the shape may be a three-dimensional structure, and may be a round shape, an elliptical shape, a triangular shape, or a square shape. Such as a polygonal shape or a combination of two or more of these.

  The hardly-soluble boron compound particles and the hardly-soluble aluminum compound particles, which are the active ingredients, are hardly soluble, and the surface other than the portion where the particles are in contact with each other or the vicinity of the contacted portion is covered with a transparent resin. It is not or is covered with a thin film of transparent resin, so that the herbicidal active ingredient can be released slowly. For example, if aluminum is released slowly, it will insolubilize phosphoric acid in the soil, so it is an important nutrient for plants. In addition, since the herbicidal effect is great when boron is gradually released, weed growth can be prevented and moss and fungi can be prevented from occurring.

The hardly soluble boron compound powder used in the present invention is hardly soluble in water having a pH of 4 or more and less than pH 12, and the amount of the herbicidal active ingredient is very small. It is a boron compound powder that is slightly soluble and increases the amount of the herbicidal active ingredient dissolved.
Specific examples of the boron compound include, for example, natural minerals such as colemanite, urexite, price stone, borohydrite, hydroborite, indium stone, cyberite, dolite, howlite, and borumite, and boric acid, Examples thereof include glass in which oxalic acid glass containing borax is baked at 200 to 1000 ° C., preferably 700 to 900 ° C., and the amount of boron eluted is controlled, and a mixture of two or more of these.

Insoluble in water with a pH of 4 or more and about pH 5-8, the amount of dissolution is very small, but slightly soluble in water below pH 4 or below pH 5 or above pH 8, and the amount of active ingredient dissolved increases. Such an aluminum compound powder.
Specific examples of the hardly soluble aluminum compound include kaolin clay minerals (kaolinite, halloysite, sericite, wax, etc.). When using a rock stone as the hardly soluble aluminum compound granular material, it is better to roll it with a roller or the like, and it will be solid and firm, and it will be less likely to generate dust even if the wind blows. It is easy to obtain and has a higher herbicidal effect.

  In the herbicidal material of the present invention, 0.5 to 5% by mass, preferably 1 to 3% by mass, and a particle size of 10 mm to 7% to 0.04 mm, preferably 5 mm to 2 mm of a hardly soluble boron compound powder. When the hardly soluble aluminum compound of 0.04 mm, preferably 8 mm to 2 mm is blended in an amount of 99.5 to 95% by mass, preferably 97 to 99% by mass, it is excellent in handleability in the form of a granular material and is applied to the ground. It is preferable because it has excellent properties, has an excellent herbicidal effect, and hardly generates dust even when the wind blows.

If the particle size of the hardly soluble boron compound powder exceeds 7 mm, it may be difficult to control the elution of the active ingredient, and if it is less than 0.04 mm, dust may be generated. If the amount of the hardly soluble boron compound powder is less than 0.5% by mass, the herbicidal effect may be inferior. If it exceeds 5% by mass, the herbicidal effect is excellent, but there is a risk of environmental pollution.
If the particle diameter of the hardly soluble aluminum compound granular material exceeds 7 mm, it may be difficult to control the elution of the active ingredient, and if it is less than 0.04 mm, dust may be generated. If the blending amount of the hardly soluble aluminum compound powder is less than 95% by mass, the herbicidal effect may be inferior. If it exceeds 99.5% by mass, the blending amount of the hardly soluble boron compound is insufficient, and the herbicidal effect is poor. There is a fear.

The transparent resin aqueous emulsion used in the present invention is obtained by dispersing a transparent resin in water using a dispersing agent to form an emulsified state.
The transparent resin used in the present invention may be a thermoplastic resin and / or a thermosetting resin as long as it has transparency. For example, polyester, polystyrene or styrene copolymer (for example, styrene-acrylic resin). , Styrene-butadiene resins, etc.), acrylate and methacrylate resins, polyvinyl chloride resins, vinyl acetate resins, vinyl chloride / vinyl acetate copolymer resins, vinyl chloride / vinyl acetate / maleic acid copolymer resins, vinyl butyral resins, polyvinyl alcohol resins. Any of polyurethane resin, polyimide resin, polyamide resin, polyether resin, epoxy resin, or a mixture of two or more thereof can be used.
The transparent resin aqueous emulsion used in the present invention can be prepared in-house, but a commercially available product (for example, trade name: Narsuwaro (registered trademark), manufactured by Naruse Chemical Co., Ltd.) can also be used.
Transparent thermosetting resin used in the present invention

  In order to improve the properties such as flexibility, impact resistance, and hardness of the transparent resin used in the present invention, a styrene-diene block copolymer, a polyurethane elastomer, a polyester-ether copolymer, a polyolefin elastomer, etc. An elastomer or other organic polymer can be added and blended within a range that does not impair the transparency of the transparent resin.

  The transparent resin aqueous emulsion used in the present invention has the property of exhibiting an adhesive function by allowing the water contained therein to gradually evaporate when left in the atmosphere and to become sticky when dried. And, when drying is finally completed, it is solidified (cured), and a part where the hardly soluble boron compound powder and the hardly soluble aluminum compound powder of the active ingredient are in contact with each other or the vicinity of the contacted part becomes a joint part, Since it joins by transparent resin, the water-permeable three-dimensional structure 6 of this invention excellent in intensity | strength can be obtained.

  Since the gaps are continuous with each other except the joints, when rainwater passes through the gaps and is absorbed by the ground, the amount of boron and the like is controlled and the active ingredient is supplied to the ground. Can do.

That is, the surface other than the portion where the powder particles are in contact with each other or the vicinity of the contacted portion is not covered with the transparent resin or is covered with a thin film of the transparent resin, and the surface of the powder particles is the transparent resin. If it is not covered by the rainwater, etc., when the rainwater passes through the gap, the active ingredient is eluted directly into the rainwater that comes into contact, but if it is covered by a thin film of transparent resin, the thickness of the film, Depending on the physical and chemical properties of the membrane, the amount of elution of active ingredients eluted in rainwater varies.
Control the controlled release of herbicidal active ingredients by measuring the thickness of the film, the physical and chemical properties of the film, the molecular weight of the transparent resin, etc. can do.

  The thickness of the thin film of the transparent resin also varies depending on the transparent resin content in the transparent resin aqueous emulsion. Therefore, the transparent resin aqueous emulsion can be used as a stock solution as described above. It is also possible to obtain a granular material covered with a thinner film thickness by using a transparent resin aqueous emulsion diluted at a magnification of 2 times, 2 times, 3 times, etc. and diluted with water.

  If an aqueous emulsion of transparent resin diluted with water is used, the amount of transparent resin at the point where the particles are in contact with each other decreases and the strength may decrease. It is preferable to control by reducing the thickness of the active ingredient to increase the elution amount of the active ingredient.

  As shown in FIG. 2, a predetermined amount of a hardly soluble boron compound powder and a hardly soluble aluminum compound powder are mixed in advance with the transparent resin aqueous emulsion used in the present invention, and the mixture is mixed at the construction site. , Except for weeds, etc., roots are also rooted, leveled, applied to the ground surface, and remain in the vicinity of or in contact with the poorly soluble boron compound particles and the hardly soluble aluminum compound particles Other than the above, after discharging out of the system, it can be dried and cured to obtain the water-permeable three-dimensional structure of the present invention.

  One of the transparent resins used in the present invention is polyvinyl alcohol having a saponification degree of 95% or more. When the saponification value is small, the solubility in water is high. On the other hand, when the saponification degree is 95% or more, the solubility in water is high. Therefore, it is possible to use an aqueous emulsion of a polyvinyl alcohol component having a high degree of saponification, and it is possible to exhibit strong water resistance that is not dissolved by rainwater after drying and curing.

  In the herbicidal material used in the present invention, a bulking agent such as a filler and a third component such as a cat repellent material can be blended depending on the intended use within a range that does not impair the performance of the herbicidal material.

  Cat repellent materials include wood vinegar, bamboo vinegar, menthol, and the like.

  As the packaging of the herbicidal material used in the present invention, a known highly waterproof package can be used. Specifically, a PE bag, a paper plastic laminated bag, etc. can be mentioned, for example.

  The description of the above embodiment is for explaining the present invention, and does not limit the invention described in the claims or reduce the scope thereof. Moreover, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.
