されていない。However, the above-mentioned herbicidal active ingredient is usually diluted as a concentrated solution with water and then sprayed on the foliage of weeds. The main salts of [(3-amino-3-carboxy)propyl-1]methylphosphinic acid have been reported in JP-A-58-18311 to be used in combination with nitrogen atom-containing compounds such as ammonia nitrogen-containing compounds to have medicinal effects. It is disclosed that this method enhances granules, and also describes the application of both as fine granules, but no detailed formulation examples of fine granules are described.

定の除草活性成分への適用に限られている。On the other hand, it has been difficult to obtain fine granules that satisfy all of the main requirements for formulation, storage, and dispersion in terms of shape retention, adhesion to weed stems, and expression of medicinal efficacy. The application of fine granules, for example, is limited to specific herbicidal active ingredients with low hygroscopicity.

。(Problem to be Solved by the Invention) The reason why the herbicidal active ingredients are sprayed together with a large amount of diluted water is that they are not absorbed much through the roots and act by contact and penetration in the shoots and leaves. Therefore, consideration was given to making sure that it adhered to the stems and leaves as evenly and as evenly as possible.

対する安全性が問題となる傾向もある。However, with this method, it is difficult to spray in areas where it is difficult to obtain and transport diluted water, such as in mountainous areas with poor footing, and aerial spraying using helicopters or airplanes can cause chemical damage to useful crops due to the spraying of the chemical solution. There is also a tendency for safety for humans and livestock to become an issue.

ことになる。(Background of the invention) Although the herbicidal active ingredients are solid at room temperature, they have extremely high deliquescent properties, so even if they are simply formulated into fine granules, they absorb a small amount of water or moisture in the air and become granules. The surface becomes sticky or the grains form agglomerates, which ultimately makes it impossible to apply it to a granulator or the like, which impedes the spraying work. On the other hand, if excessive waterproofing/moisture-proofing treatment is applied to avoid these problems,
It does not adhere to the stems and leaves and falls into the soil, resulting in a lack of medicinal efficacy.

の脱離性が劣り、従って薬効も充分でない。According to the fine granules of the present invention, the herbicidal active ingredient is well retained on or near the surface of the solid carrier, so that the fine granules do not break or the herbicidal active ingredient peels off during the storage or dispersion stage after formulation. In addition, it does not deliquesce, retains its shape well as a fine granule, and does not interfere with spraying operations. On the other hand, the herbicidal active ingredient absorbs moisture under natural conditions such as dew on the right rear stem and leaves, moisture in the air in the vicinity, or water vapor due to the transpiration of plants, resulting in herbicidal activity Iu.
Since the components self-dissolve, the fine particles adhere well to the foliage and spread, acting on weeds, resulting in high medicinal efficacy. In addition, compared to the case where a water-insoluble solid carrier is used, the adhesion of the fine particles to the foliage or the spreadability of the herbicidal active ingredient in the foliage increases, so the medicinal efficacy is stabilized or improved. You can expect it. On the other hand, when a solid carrier such as bentonite in Comparative Fine Granules Example 6 is used, the adhesion of the grains to the leaf surface and the ability to remove the herbicidal active ingredient from the grains during spraying are poor, and therefore the medicinal efficacy is insufficient. Not.

Butyryl) alanylalanine or a salt thereof can be provided with suitable fine granules, making it possible to apply the herbicidal active ingredient even in situations where conventionally it was impossible or difficult to spray as a liquid. It is also possible to eliminate or reduce the effects on crops and humans caused by the spraying of chemical solutions. *The said fine granules absorb water well under natural conditions in the foliage of weeds, and the herbicidal active ingredient self-dissolves, as well as the entire amount of dissolved carrier, and spreads over a wide area on the foliage of weeds. Since it acts in a widespread manner, sufficient medicinal efficacy can be obtained, and medicinal efficacy comparable to that achieved by spraying a liquid agent can be obtained.
