Insecticide composition for water spray

The present invention is directed to a pesticide composition for sleep application comprising a pesticide active ingredient, a solid wax material and a water soluble carrier which are solid at room temperature, homogeneously mixed and formulated. More specifically, the present invention is a surface spray prepared to exhibit the desired pesticidal effect by efficiently floating and spreading the pesticide active ingredient powder on the surface of the water together with the solid wax material powder when the pesticide formulation is spread over the surface of the rice paddy. It relates to a pesticide composition for.

Up to now, the method of suspending the pesticide granules has been proposed as a method of effectively applying the pesticide active ingredient as described below.

1. A method of adsorbing an insecticide active ingredient to a floating carrier (e.g. pumice) by adding a water repellent, if necessary, in order to suspend the granulation of the insecticide active ingredient [Japanese Patent Publication Nos. 44-8,600, 47-. 1,240, 48-1,181 and 48-1,182 and Japanese Laid-Open Patent Publications 55-139,308 and 58-65,203.

2. A method of adsorbing an insecticide active ingredient dissolved or dispersed in a wax material to a water-soluble carrier and other materials (see Japanese Patent Laid-Open Nos. 56-30,901 and 57-38,702).

3. A method of formulating a slightly water-soluble or water-insoluble pesticide active ingredient using a water-soluble carrier comprising a water-soluble carrier and a film-forming substance (Japanese Patent Laid-Open No. 60-142,901).

4. A method of adsorbing an insecticide active ingredient to a solid carrier by dissolving or dispersing the insecticide active ingredient in a high boiling point solvent having a specific gravity less than 1 (Japanese Patent Laid-Open No. 63-17,802).

5. A method of adsorbing an insecticide active ingredient to a solid carrier by dissolving or dispersing the insecticide active ingredient in a high boiling point solvent having a surfactant having a HLB of less than 6 and a specific gravity of less than 1 [Reference: Japanese Patent Laid-Open No. 1-254,604 number].

6. A method of adsorbing an insecticide active ingredient to a solid carrier by dissolving or dispersing the insecticide active ingredient in an oil having a specific gravity less than 1 to form an oil film on the surface of the surface (Japanese Patent Laid-Open No. 3-193,705).

While these conventional methods have been provided for the effective use of pesticide active ingredients by increasing the dispersion and dissolution of the pesticide active ingredient in water or by reducing the adsorption of the pesticide active ingredient to the soil, there are fundamental problems to be solved, each of which is also a real problem. The operation is complicated in terms of use and its manufacture.

That is, in the method 1 described above, the granules have sufficient oil adsorption characteristics, but these are expected to be easily affected by the wind because of their lighter weight, so that the granules floating on the water after spraying them tend to be pushed to one side. Sometimes lowers the effect. In addition, from a manufacturing standpoint, this method requires an operation that requires dissolving the solid active ingredient in a suitable solvent to impregnate the granular matrix.

On the other hand, in Method 2, in which the insecticide active ingredient is suspended together with the wax material on the surface of the water and effectively sprayed, the ingredient used is limited to a solid ingredient compatible with the wax material. In addition, a heating operation is also necessary to liquefy the wax material that dissolves or disperses the components during the preparation of the pesticide.

In Method 3, wherein the liquid pesticide active ingredient is suspended above the water surface using a water-soluble carrier and a film forming material, the adsorption capacity of the active ingredient on the carrier is insufficient, thus limiting the range of ingredients used.

Furthermore, in methods 4, 5 and 6, in which higher alcohols, fatty acid esters, silicone oils, mineral oils and the like are used as high boiling point solvents having a specific gravity of less than 1, the active ingredients used because the solubility of these solvents are insufficient as in the case of method 3. It also limits the scope of.

Very preferred as a feature of the sleep spraying insecticide composition is to effectively apply its pesticidal activity by floating and spreading the sleep spraying insecticide composition on the surface of the water. However, the techniques for preparing these pesticide compositions are limited by the physical properties of the pesticide active ingredient used and the absorption capacity of the pesticide active ingredient on the carrier. In addition, there are manufacturing problems that require a process, for example, a process for dissolving or dispersing a component in a solvent.

In order to solve the problems described above, the inventors' intensive research shows that the insecticide composition for spraying the surface and its composition, which shows unexpectedly superior effect to the conventional insecticide without the need for dissolving or dispersing the insecticide active ingredient in a solvent or the like. A manufacturing method was found.

According to the present invention, a pesticide composition for sleeping spraying comprising a pesticide active ingredient, a solid wax material and a water-soluble carrier, which is solid at room temperature, homogeneously mixed and formulated, and a wet spraying or compression tableting, It provides a method of manufacturing.

The method described in Example 1 is repeated using the components and compounding ratios shown in Table 1.

[Examples 7 to 9]

The method described in Example 1 is repeated using the ingredients and formulations shown in Table 2.

[Comparative Examples 1 to 3]

The comparative composition shown in Table 3 is prepared by a similar method as in Example 1.

[Test Example 1]

[Sleep Floatability Test]

A 100 × 100 × 10 (cm) container made of stainless steel was filled with water less than 5 cm deep, left to stand, and then 3 g of each sample species prepared in the above-described and comparative examples was placed in the center of the container. Spray it nearby to handle it carefully.

One hour after this treatment, 47 mm diameter glass wool filter paper was carefully suspended on the water surface of each corner of the container, completely immersed in water and collected, then placed in a test tube, and the solvent was extracted. Each active ingredient attached is analyzed.

The sleep susceptibility of the pesticide active ingredient is calculated by assuming that the amount of adhered per area of the filter paper is 100 when such ingredient is suspended and developed. The results obtained are shown in Table 4.

As shown in Table 4, it can be seen that when the present composition is sprayed, the pesticide active ingredient floats and develops rapidly above the water surface.

[Test Example 2]

[Stain disease control test]
