However, although these methods are intended to effectively utilize the agricultural chemical active ingredient by promoting diffusion and elution of the agricultural chemical active ingredient into water or by reducing soil adsorption, it is still insufficient in practical use. In addition to the above points, it requires a complicated process in terms of manufacturing. That is, in the method described in, since it is made lighter for the purpose of floating the granules on the water surface, it is easily affected by the wind during spraying, and the granules floating on the water surface after spraying are blown to one side by the wind. There are problems, and moreover, a complicated manufacturing process is required, so that there is a problem in economical efficiency. The method described in 1) floats the agrochemical active ingredient together with the wax-like substance on the water surface to effectively act, but is limited to the solid agrochemical active ingredient having an affinity for the wax-like substance.

In the method described in [1], a liquid pesticide active ingredient is suspended on the water surface by using a water-soluble carrier and a film-forming substance. There are restrictions on the active ingredients.
The methods described in, and, use higher alcohols, fatty acid esters, silicone oils and mineral oils as high boiling point solvents having a specific gravity of 1 or less, but these solvents have a poor dissolving power and dissolve. There are restrictions on the pesticide active ingredients that can be produced. Further, in recent years, there has been a strong demand for labor saving in the spraying of agricultural chemicals, and many technologies relating to throw-in formulations containing a foaming agent have been disclosed, but since deterioration of foaming performance with time is inevitable, there is a major obstacle to practical use. Exists. In addition,
Although many techniques for packaging a granule or granules obtained by the technique disclosed in US Pat. No. 6,096,096 into a water-soluble film to make a throw-in formulation are disclosed, these techniques package the granules or granules in a water-soluble film after preparation. It requires a process, the manufacturing cost is high, the spreadability on the water surface and in water is inferior to that of the preparation containing a foaming agent, and there is a problem of local soil residue.

No. 0) etc. are disclosed, but these methods also aim at effective utilization of the pesticidal active ingredient by promoting diffusion and dissolution of the pesticidal active ingredient in water, but various problems occur in practical situations. There is still not enough. That is, since the method of (1) requires complicated steps for preparing the composition, the manufacturing cost is high, and the method of (1) is simple in preparation of the composition only by mixing, but the specific gravity of the pesticide active ingredient is usually 1
It is larger and quickly settles in water, and sufficient diffusivity cannot be obtained.
