When the active ingredient is a solid, the packaged agricultural chemical preparation of the present invention first contains only the active ingredient or a surfactant, a carbonate,
After mixing with any or all of the solid acids, the mixture is pulverized with a dry pulverizer such as a jet miser, a pin mill, a hammer mill and the like, and then the remaining components are mixed to obtain a powder. If the active ingredient is liquid or liquid by the addition of a solvent, after the active ingredient is absorbed into a calcined product of wet-process silica or dry-process silica, a powder is obtained in the same manner as described above. .

The powder thus obtained may be directly contained in water-soluble paper, but from the viewpoint of fluidity during production, etc.
After granulation or tablets, it is desirable to enclose in water-soluble paper. Of course, a mixture of granules and powder can be included in water-soluble paper. In addition, granules are obtained by granulating the above powder into granules, and the shape differs depending on the granulation method,
There are various types, from columnar and spherical to irregular. Tablets are tablets or granules prepared by compressing the powder or granules into a given shape.The shapes of the tablets are disk-shaped, solid, corners, rounded, and lens-shaped. Pillow type, from shallow to deep
There are various types such as almond type, finger type, triangle, square, pentagon, and capsule.

The granules are formed into a sheet, a pillow-like granule or a slug using a dry granulator such as a roller compactor or briquetting machine or a slug machine, and crushed with a granulator or the like. Or you can get it destroyed. The granules may be subjected to a spheroidizing treatment using a marmellaizer or the like from the viewpoints of preventing dusting when the granules are included in water-soluble paper and improving the appearance of the product. When using a dry granulator, place the powder composition between rotating rolls and
A pressure of at least kg / cm ² , preferably at least 50 kg / cm ² is applied. The particle size of the above granules is usually about 10,000 μm or less, preferably about 4000 μm or less.

Tablets can be obtained by placing the powder into a mortar in a fixed amount and compressing it. Industrially, the above powders or granules are used on a tableting machine or briquetting machine. By tableting, tablets of a constant weight can be obtained continuously.

Although the size of the tablet is not particularly limited, it is usually about 7 to 50 mm in diameter and about 1 to 30 mm in thickness, and the weight per tablet is about 0.1 to 50 g, preferably about 1 to 10 g.

The packaged pesticide preparation of the present invention is obtained by enclosing a suitable amount of the above-mentioned powder, granules and / or tablets, usually 5-1000 g, preferably 10-500 g, in water-soluble paper. At this time, the apparent specific gravity of the composition contained in the water-soluble paper can be made 1 or more in order to speed up the dissolution of the water-soluble paper and improve the diffusibility of the active ingredient. In that case, weights such as clay, stone, glass beads, and alumina balls may be added to the composition.

As a method of encapsulating in water-soluble paper, various methods such as use of glue or double-sided tape can be mentioned, but a method of heat sealing is industrially preferable. That is, the packaged agricultural chemical formulation of the present invention can be obtained by sandwiching the contents between water-soluble papers or putting them in a water-soluble paper bag and closing them by heat sealing such as impulse sealing.

When the packaged pesticide preparation of the present invention is applied to a flooded sewage paddy field, the amount of application varies depending on the type and amount of the active ingredient, but it is usually about 50 per 10 ares based on the weight of the composition excluding water-soluble paper and weight. ~ 2000g, preferably about 500-1000g
It is. The application time varies depending on the type of active ingredient and the like, but is usually from after scratching until about 2 weeks after heading. In particular, in the case of a packaged pesticide preparation containing a herbicidal active ingredient, the application time is preferably from after scratching to about 15 days after rice planting.

When the packaged pesticide preparation of the present invention is applied as it is, usually no special equipment is required. For example, the application can be performed from a ridge or a waterside without entering into a paddy field, a pond, a moat, a swamp, a river, or the like. You can also enter a pond, moat, swamp, river, etc. by boat or boat and throw it in,
It can also be sprayed from the air using an airplane, a radio-controlled airplane, or the like.

Further, when the packaged pesticide preparation of the present invention is applied to a flooded sewage paddy field, it may be manually introduced from above the rice transplanter or dropped from the rice transplanter at regular intervals.

[0077] The packaged pesticide preparation of the present invention can be used in flooded sewage fields,
When applied to ponds, moats, swamps, rivers, etc., after the water-soluble paper is dissolved,
The contents generate carbon dioxide gas and move, and the active ingredient is quickly and uniformly diffused in water. Therefore, the pesticide active ingredient pests (pests, disease bacteria, weeds, etc.) are controlled against pests. Alternatively, the composition is an excellent composition in that the plant growth regulating active ingredient exerts a sufficient effect on crops and is evenly dispersed, so that phytotoxicity to crops is reduced. Further, the pesticidal preparation of the present invention is a composition having a characteristic that it can be accurately applied to a distant place by hand, so that it can be appropriately applied to a place where it is desired to be applied. Further, it has a feature that there is no dusting at the time of application and odor and irritation can be reduced.

When the packaged pesticide preparation of the present invention is applied to a paddy field, it can be applied at a conventional application rate (for example, in the case of granules, 10 ares).
In some cases, the application rate can be significantly reduced as compared with (3,000 to 4000 g), and in such a case, the application value is high in terms of production, transportation, storage, and labor-saving spraying of the product.
