A preparation such as a granule or a tablet, which is put in a bag made of a water-soluble polymer in a pack, needs to ensure a function of uniformly diffusing the active ingredient more than required for a normal granule or tablet. The application with a pack is a local application that is applied to several paddy fields to save work, and the water-soluble bag of the injected pack dissolves and the contents of the agrochemical formulation are transferred to the paddy field. This is because the purpose is to control the entire surface of the treated paddy by uniformly dispersing (Non-Patent Document 1).
In the case of packs consisting only of conventional granules (particulates), if the diffusion performance is insufficient and it takes time to diffuse, it will be blown to one side of the paddy field, or the granules will settle down in one place and cause chemical damage. There was a problem that occurred.
Therefore, in the examination of the formulation of granules or tablets used in packs, the combination of agrochemical active ingredients and various active agents, bulking agents, etc. must be examined in order to ensure the function. It took time and effort. Further, depending on the combination of the activator and the like, there are cases where aggregation, reaction, etc. occur and cannot be mixed. Furthermore, even the finished product of the preparation cannot sufficiently exhibit the diffusion effect, so that the effect of the pesticidal active ingredient may become unstable, and the occurrence of phytotoxicity may be promoted. In addition, when a large amount of an activator is added to improve the diffusion performance, or production is performed using a granulation operation (extrusion method), the production cost may increase and it may become uneconomical.

In general, wettable powders and powders can be easily produced at a low production cost compared to granules and tablets, and therefore, many products have been developed as agricultural chemical formulations.
However, powdered products (wettable powders, powders) are used in packs because they are a formulation technology developed for the purpose of uniform diffusion treatment by the workers themselves, either diluted with water or as they are. There is no need to impart a high degree of diffusibility like granules and tablets. Therefore, there is no known example in which a powdered material such as a wettable powder or powder is used for the pack. Moreover, even when a prototype using a normal powdery product as a pack was manufactured and a diffusion experiment was performed, aggregation and the like occurred and a sufficient diffusion production method was not exhibited. However, there are products in the form of packs for the purpose of avoiding dangers such as inhalation and exposure of workers from dusting during use.
In general, a powdery product is solidified by receiving pressure during storage, and may not exhibit sufficient performance.
Under such circumstances, the production cost is low and the powdery material can be diffused promptly and uniformly on the surface of the rice field, and the effect of the agrochemical active ingredient carried on the powdery material by this diffusion effect. There is a need for the development of a new formulation technique for a powdered product that can be used in a pack that can fully exhibit the above.

  As a result of diligent research to solve the above-mentioned problems, the present inventors have improved the diffusion performance when using powdered materials such as wettable powder and powder as a pack agent. A formulation in which a granular material, which is supported (including adsorption and impregnation) by an impreg method that can manufacture a component having malleability) (hereinafter referred to as a diffusing agent) at low cost, is added to a powdered material, When the pack agent is applied to the water surface, the active ingredient carried on the powdery material can be uniformly applied to the paddy field by spreading and spreading the powdery material quickly and uniformly around the granular material. And the present invention was completed.

That is, the present invention

About.

Since the preparation of the present invention comprises a granular material containing a diffusing agent and a powdery material carrying an active ingredient such as an agricultural chemical, the water-soluble pack dissolves when dropped into a flooded sewage paddy as a pack agent, and the contents As a result of the effect of the diffusing agent eluted from the granular material, the powdery material on which the pesticidal active ingredient is supported floats on the water surface or spreads uniformly and rapidly in water, and the pesticide supported on the powdery material. The active ingredient can also be uniformly diffused in the paddy field to fully exhibit the efficacy of the agrochemical active ingredient.
In general, a powdery material is smaller and lighter than a granular material, and therefore is more likely to receive the water surface spreading effect of a diffusing agent contained in the granular material more effectively than the granular material. Therefore, the powdery material according to the present invention can be more uniformly and rapidly developed on the water surface than the conventional granular material. Therefore, the conventional phytotoxicity to paddy rice caused by blowing floating substances and the nonuniformity of pesticide application due to insufficient diffusion caused by sedimentation in one place do not occur.

Comparative Example 1 Production of Packing Agent 75 g of the powdery product obtained in Comparative Example 1-1 was filled and packaged in a bag made of polyvinyl alcohol film (thickness 40 μm) to obtain an agrochemical formulation (packing agent).

Effect test example 1
About 18 a paddy field about 15 days before heading (34 × 53 m, water depth 10 cm), 18 75 g packs prepared in Example 1, and another 75 g pack manufactured in Comparative Example 1 in the same size paddy field 18 agents were added so as to be almost uniform from the shore, and the amount of the pesticidal active ingredient in the rice water after 3 hours and 24 hours after the treatment was quantified using a liquid chromatograph. In addition, as shown in FIG. 1, the sampling location is 4 points every 10 m from the position of 2 m from the end of the long side of the partition, and 5 points from the position of 1.5 m from the end of the short side every 5 points. A point (positions a to t in the figure), a position 5 cm deep from the surface of the rice field.
As a result, the pack agent of Example 1 detected active ingredients at all 20 points after 3 hours. Further, after 24 hours, active ingredients close to the theoretical amount were detected at each point, and no large variation was observed. On the other hand, no active ingredient was detected at several points in the pack agent of Comparative Example 1 even after 24 hours. The detection result of the amount of active ingredients is shown in Table 1 (unit: g / L).
Then, as a result of investigating the effect on the leaf blast and the head blast disease that occurred in the same section, in Example 1, no problem was found in the control effect, and no phytotoxicity was observed.
However, in Comparative Example 1, mild phytotoxic symptoms were observed at point a.

ＣＶ（変動係数）は、母集団の母標準偏差と母平均との比率を示し、一般的に数値が大きいほど母集団の数値のバラツキが大きいことを意味する。

CV (coefficient of variation) indicates the ratio between the population standard deviation of the population and the population average. Generally, the larger the value, the greater the variation in the population value.

Effect test example 2 Consolidation property 10 packs produced in Example 1 were filled in an aluminum foil bag and sealed, and a load of about 20 kg was applied and left at 40 ° C. for 3 months. About the pack agent of the comparative example 1, after leaving still on the same conditions, it opened, the state of the pack agent was observed, and the diffusibility in water was confirmed.
As a result, in Comparative Example 1, the preparation of the contents was hard and blocked, and did not diffuse even when dropped in water. On the other hand, the pack agent of Example 1 did not cause blocking, and the diffusion after dropping in water was as good as the product immediately after production.
