It can produce excellent effects such as being friendly and friendly.

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.

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.

Specific examples of the hydraulic cement used in the present invention include Portland cements, silica cement, blast furnace cement, fly ash cement, alumina cement, and lime slag cement. Among them, Portland cement or slag cement is inexpensive and easily available, and can form a herbicidal material layer that easily solidifies on the ground.
It is preferable to add a sufficient amount of hydraulic cement for solidifying the herbicidal material of the present invention. Specifically, the blending amount is 10 to 20% by mass with respect to the herbicidal material of the present invention. If it is less than 10% by mass, a solidified herbicidal material layer may not be formed. If it exceeds 20% by mass, the herbicidal effect is excellent, but there is a risk of environmental pollution.

Magnesium chloride used in the present invention is not particularly limited as long as it can form a herbicide layer easily solidified on the ground, and commercially available ones can be used. It is preferable to add a sufficient amount of magnesium chloride for solidifying the herbicidal material of the present invention. Specifically, the blending amount is 1 to 10% by mass with respect to the herbicidal material of the present invention. If it is less than 1% by mass, a solidified herbicidal material layer may not be formed. If it exceeds 10% by mass, the herbicidal effect is excellent, but there is a risk of environmental pollution.
Since magnesium chloride is neutral, the action of the hardly soluble aluminum compound powder is not impaired, and the amount of the herbicidal active ingredient dissolved is reduced by the action of the hardly soluble boron compound powder and the hardly soluble aluminum compound powder. Since it can be controlled and released slowly, it can prevent the growth of weeds and can prevent the occurrence of moss and mold, and has excellent sustainability.

The herbicidal effect, moss and fungicidal effect after 6 months and 2 years, and the boron concentration after the dissolution test were evaluated in the same manner as in Example 1. Table 1 summarizes these results.

  It can be seen from Table 1 that the herbicidal material and the herbicidal solidifying material of the present invention are excellent in workability and the herbicidal, mossy and fungicidal effects. In contrast, Comparative Example 1 containing no colemanite is inferior in herbicidal effect and contains colemanite, but comparative example 2 using silica sand without using a hardly soluble aluminum compound granule (waxite) is workability. In Comparative Example 3, which was inferior in herbicidal effect and contained poorly water-soluble aluminum compound granules (waxite) but did not use poorly water-soluble boron compound granules (Colemanite), but used water-soluble borax. The comparative example 4 using slaked lime is inferior in herbicidal effect after 6 months, and the solidified type comparative example 5 containing no colemanite is herbicidal. It can be seen that Comparative Example 6, which is poor in moss-proofing and anti-fungal effects and only mowing, is inferior in the herbicidal effect.

The herbicidal material and the herbicidal solidifying material of the present invention can be easily applied to the ground in the form of a granular material, dust is hardly generated even if the wind blows, and it is frozen in the winter and cracks occur. In addition, since the hardly soluble boron compound particles and the hardly soluble aluminum compound particles are hardly soluble, the herbicidal active ingredient can be released slowly. For example, when aluminum is released slowly, phosphorus in the soil Since it makes the acid insoluble, it can deplete important nutrients in the plant, and when the boron is released slowly, the herbicidal effect is great, thus preventing the growth of weeds and preventing the occurrence of moss and mold. Because it has excellent sustainability, it can be used effectively for cemetery and cemetery weeds, parks and median strips, garden approaches and dog-running weeds, under steel towers, underpasses, intersections, and roadside weeds. It can be made cheap and environmentally friendly Exhibit the effect,
The construction method of the herbicidal material of the present invention can be easily constructed on the ground such as a cemetery, a cemetery, a park, a median strip, a garden approach, a dog run, a steel tower, an underpass, an intersection, a roadside belt, etc. Since it has a remarkable effect, it has high industrial utility value.
