Description

Sleep spraying insecticide compositions, coatings thereof and methods for spraying the same

The present invention provides at least one powder (1) selected from the group consisting of a powdered insecticide active ingredient melted or dispersed in a solid waxy material, a powdered mixture of the solid waxy material and a water repellent insecticide active ingredient, and a powdery water repellent insecticide active ingredient, HLB It relates to a surface spray insecticide composition comprising a nonionic surfactant (2) of 8 or less and a fluid improving agent (3) that is insoluble or poorly water-soluble.

More specifically, the present invention is to spray and spray the powdered pesticide active ingredient present in the sleep spraying insecticide composition along with the other ingredients present in the insecticide composition to the surface of the insect pests, weeds, etc. due to the effective action of the pesticide active ingredient A novel technique for controlling and weeding.

Up to now, the spraying method of floating the granular insecticide has been studied as a method of effectively using the pesticide active ingredient. This method can be illustrated as the following methods.

A method of adsorbing a pesticide active ingredient to a floating carrier (e.g., pumice) in order to suspend the granulation of the active ingredient (1) [Reference: Japanese Patent Nos. 44-8,600, 47-1,240 Nos. 48-1,181 and 48-1,182, and Japanese Laid-Open Patent Publications 55-139,308 and 58-65,203.

A method of formulating an insecticide active ingredient dissolved or dispersed in a beeswax material together with a water-soluble carrier and other ingredients (see Japanese Patent Application Laid-Open No. 56-30,901 and No. 57-38,702). number].

A method (3) in which a poorly water-soluble or water-insoluble insecticide active ingredient is formulated with a solid carrier including not only a water-soluble carrier but also a film-forming substance (see Japanese Patent Laid-Open No. 60-142,901).

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

A method of formulating an insecticide active ingredient with a solid carrier by dissolving or dispersing the insecticide active ingredient in a solvent having a high boiling point, a specific gravity of 1 or less and a HLB 6 or less surfactant (5). Publication No. 1-254,604].

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

Although these conventional methods effectively utilize the pesticide active ingredient by dispersing or eluting the pesticide active ingredient in water or reducing the adsorption of the active ingredient to the soil, these methods are still unsatisfactory in their practical use and are not fully manufactured. Process is also required.

The problem with the method (1) is that it is easily affected by wind because the granules are light enough to float on the surface of the water. Granules suspended on the surface after spraying granules tend to drift in one direction. In addition, the process requires a complete manufacturing process, which causes economic problems.

On the other hand, the problem of the method (2) of effectively applying the pesticide active ingredient by floating it on the water surface together with the waxy material is that the ingredients used are limited to solid ingredients which are affinity to the waxy material during the preparation of the pesticide. to be.

In the method (3) in which the liquid pesticide active ingredient is suspended on the water surface together with the water-soluble carrier and the film-forming substance, only a small amount of the active ingredient can be formulated with the carrier. Pesticide active ingredients used effectively herein are limited.

In methods (4), (5) and (6) in which higher alcohols, fatty acid esters, silicone oils, mineral oils and the like are used as solvents having a high boiling point and specific gravity of 1 or less, these solvents have poor solubility and thus active ingredients to be dissolved. Limit the amount of.

Although the methods of spreading pesticide formulations containing blowing agents have been variously studied in response to strong demands for saving labor, they present particularly serious problems due to the inevitable denaturation of such blowing agents.

Also described is a similar method of spraying pesticide formulations prepared by coating the granule or particulate product of methods (1) to (6) with a water-soluble membrane. Differential membrane coating processes are required after preparing these products, which increase the production cost and also lower the spraying properties of the pesticide formulation. In other words, the pesticide formulation is not evenly sprayed into the soil.

To solve these problems, the following formulations and compositions are described.

(7) water-dispersible solid formulations containing nuclear particles having an apparent specific gravity of 1 or less, insecticide active ingredients, surface tension modifiers, oil ingredients and the like (JP-A-5-155,703); (8) Powder compositions comprising pesticide active ingredients, anionic surfactants and inorganic or organic carriers having a particle size of less than 50 μm and which can be dispersed quickly below the water surface (Japanese Patent Laid-Open No. 5-155,709) ); And (9) a powder composition comprising an insecticide active ingredient, an anionic surfactant, glass hollow particles having a particle size of less than 100 μm, and an inorganic or organic carrier, and which can be rapidly dispersed below the surface of the water. ) 6-32,170).

Dispersion or dissolution of these described pesticide active ingredients is accelerated and utilized much faster in water, but these formulations and formulations are not sufficient to solve practical problems.

For example, in the case of (7), the formulation is prepared by a complicated process that increases the production cost. On the other hand, the compositions of (8) and (9) above can be easily prepared by simply mixing the starting materials, but the specific gravity of the pesticide active ingredient is generally greater than 1 so that it precipitates quickly and there is insufficient dispersion in water.

The surface spray insecticide composition is preferably suspended in nature and dispersed in water to sufficiently exhibit its insecticidal effect. In practice, however, the process for the preparation of such compositions is so complex that the manufacturing cost is increased, while the expected desired biological effect is hardly obtained because the properties and amounts of the pesticide active ingredient used therein are limited.

In order to solve the above-mentioned conventional problems, the present inventors have conducted in-depth study, and the present invention can unexpectedly exhibit an excellent effect compared to the prior art, and can be simply prepared a surface sprayable pesticide composition and spraying the same To provide a way to do this.

[Test Example 1]

[Surface Flow Test]

Fill a vessel made of 300 × 50 × 10 (cm) stainless steel with 5 cm of water. A sample package prepared by coating 5 g of each composition of the examples and the comparative examples with a polyvinyl alcohol film is gradually applied to water from one side of the paper.

If the filter paper is completely wet, collect it and transfer it to the test tube. Each active ingredient absorbed in the filter paper is extracted and used for quantitative analysis. The floating rate of the test component was calculated by referring to the amount of active ingredient per 100 filter paper areas when such a component was completely suspended and developed on the surface of the water. The obtained results are shown in Table 2.
