In the packaged pesticide preparation of the present invention, the pesticidal active ingredients can be used singly or as a mixture of two kinds. When used in a mixture, the mixing ratio can be arbitrarily selected. The content of these active ingredients varies depending on the kind of the ingredients and the like, but is generally 0.1% based on the total amount of the composition in the water-soluble film (however, the total amount of the composition excluding the weight described below).
It is from 01 to 80% by weight, preferably from 0.1 to 50% by weight.

When these active ingredients are liquid or used after being dissolved in a solvent, they are usually used as described below.
A calcined product of wet-process silica or dry-process silica is added. However, if the ratio of the liquid component is too large, the oil absorption effect of the silica becomes insufficient, so that the liquid component is usually added to the total amount of the composition in the water-soluble film ( However, it is 0.01 to 60% by weight, preferably 0.1 to 40% by weight, based on the total amount of the composition excluding the weight described below.

The amount of the calcined product of the wet process silica or the dry process silica is usually 50 to 50 parts with respect to the whole liquid component in the case of the liquid active ingredient or the active ingredient used by being dissolved in a solvent.
It is 200% by weight, preferably 60 to 100% by weight. Examples of the calcined product of the wet process silica used include Toxir (manufactured by Tokuyama Soda Co., Ltd.), Carplex # 80 (manufactured by Shionogi & Co., Ltd.), Carplex # 67, Carplex # 1120, Carplex # 100, and Carplex 22S. , Carplex FPS-1, Carplex FPS-2, Carplex FP
S-3, Carplex FPS-4, Nip Seal (manufactured by Nippon Silica Co., Ltd.), Ultrasil (manufactured by Degussa), etc., synthetic hydrous silicon oxide (wet process silica) at 700-900 ° C., preferably 800 ° C.
What is fired at ~ 900 ° C is used. Alternatively, commercially available Carplex CS-5, Carplex CS-7, or the like may be used as it is. On the other hand, dry silica includes light anhydrous silicic acid obtained by the dry method, for example, AEROSIL200, AEROSIL300 (De
gussa).

When the melting point of the pesticidal active ingredient is about 0 to 70 ° C., a solvent is added as necessary to lower the viscosity at the time of production and to prevent crystallization of the active ingredient when stored at a low temperature. As the solvent, a non-volatile or low-volatile organic solvent is usually used. Solvents used for the purpose of adjusting the viscosity and preventing crystallization of the active ingredient include those which are uniformly mixed with the active ingredient, for example, aromatic hydrocarbons such as phenylxylylethane, ketones, esters, and vegetable oils. , Mineral oil, liquid paraffin, average molecular weight 200-600
Examples thereof include glycol ethers such as polyethylene glycol, polypropylene glycol, and polypropylene glycol methyl ether, which are liquid at room temperature at a room temperature, and acetates thereof, and phenylxylylethane, glycol ethers, and acetates of glycol ethers are particularly preferable.

The amount of the solvent to be added is generally 10 to 1000% by weight, preferably 30 to 200% by weight, based on the active ingredient.
It is. Even when the melting point of the active ingredient is 0 ° C. or lower, the above-mentioned solvent may be added as necessary to reduce the viscosity during production.

As the surfactant used in the present invention, those capable of emulsifying and dispersing the active ingredient, a calcined product of wet-process silica, and the like are used. For example, alkylaryl sulfonate, alkylnaphthalene sulfonate, lignin Sulfonate, dialkyl sulfosuccinate,

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 encapsulated in a water-soluble film. However, from the viewpoint of fluidity at the time of production, it is preferable to form granules or tablets and then encapsulate the same in a water-soluble film. . Of course, a mixture of granules and powder can be included in a water-soluble film. The granules are obtained by granulating the above powder into granules, and the shapes vary depending on the granulation method, and there are various types such as those having a columnar shape and a spherical shape and those having an irregular shape. Tablets are tablets or granules prepared by compressing the powder or granules into a certain shape.The shapes of the tablets are disk-shaped, solid, corner-shaped, rounded, and lens-shaped. There are various types from shallow to deep, such as pillow type, 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 the water-soluble film and improving the appearance of the product. When using a dry granulator, the powder composition is placed between rotating rolls and a pressure of 30 kg / cm ² or more, preferably 50 kg / cm ² or more 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 can be obtained by enclosing an appropriate amount of the above-mentioned powder, granules and / or tablets, usually 5 to 1000 g, preferably 10 to 500 g, in a water-soluble film. In this case, from the viewpoint of diffusibility of the active ingredient,
It is preferred that the composition contained in the water-soluble film has an apparent specific gravity of 1 or more. Therefore, when the apparent specific gravity is less than 1, it is preferable to add a weight such as clay, stone, glass beads, and alumina balls to the composition.

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

When the packaged pesticide preparation of the present invention is applied to flooded sewage paddy fields, the application rate varies depending on the type and amount of the active ingredient, but is usually about 10 weights per weight of the composition excluding the water-soluble film and weight. 50-2000 g, preferably about 500
~ 1000g.

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 film dissolves, the contents generate carbon dioxide and move, and the active ingredient diffuses quickly and uniformly into the water, so the pesticide active ingredient The pests (pests, pests, fungi, weeds, etc.) that control the pests or the plant growth regulating active ingredient exerts a sufficient effect on the crops and spreads evenly, thus reducing the phytotoxicity to the crops. It is also an excellent composition in terms of point. 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.
