Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for applying pesticides. More specifically, the present invention is to provide a pesticide formulation such as a wettable powder, a solution and an emulsion containing an active ingredient of a pesticide as an active ingredient easily and safely without using a large amount of water, and to exhibit a high control effect. To the application method that can be used.

[0002]

2. Description of the Related Art Examples of the form of an agricultural chemical formulation include:
Examples include wettable powders, water solvents, solutions, suspensions, emulsions, microemulsions, and granules. Of these, except for granules, dilute with a large amount of water and use a sprayer or the like. It is common to spray. However, when the use of water is inconvenient, a large amount of water must be transported to the application site, and a great deal of labor is required to dilute the agricultural chemical formulation into a large amount of water and apply it. There is room for improvement. When these pesticide preparations, especially herbicides, are sprayed in the vicinity of useful plants such as trees, plants, and ground cover plants, phytotoxicity may occur due to scattering and the like, and there are restrictions on spraying. In addition, when using a plurality of granules to spray the pesticide active ingredient in any combination and in any dose, segregation may occur due to differences in specific gravity and grain size of the granules even if they are simply mixed. It often wakes up and cannot be spread evenly.
There is a need for a method of applying pesticides that solves these problems.

[0003] As a known technique, Japanese Patent Application Laid-Open No. 2000-136103 is known.
The present invention is characterized in that a wettable powder containing a herbicidal active ingredient is used as a granular composition formed by carrying and coating a water-based nucleus of mineral particles with water, and the granular composition is sprayed on a flooded submerged paddy field. The method of applying the pesticide is described, but the grain nuclei of the mineral particles used are non-absorbent sand, and the non-absorbent sand was coated with a wettable powder using water. In such a case, since the water is retained on the surface of the sand, the fluidity of the granular composition may be deteriorated, leaving room for improvement.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted various studies to solve the above-mentioned problems, and as a result, have obtained agricultural chemicals such as wettable powders, solutions and emulsions which are used after being diluted with a large amount of water.

Among the above pesticidal active ingredients, those of a soil treatment type are desirable. The above-mentioned pesticidal active ingredients can be used alone or in combination of two or more. When two or more pesticide active ingredients are used in combination, a single pesticide formulation containing two or more pesticide active ingredients may be used, or a plurality of pesticide formulations containing different pesticide active ingredients may be used. May be used. When a plurality of pesticide preparations are used, if a plurality of granules are mixed and sprayed as in the related art, segregation occurs due to differences in the specific gravity and grain size of each granule, and uniform spraying is often impossible. On the other hand, according to the application method of the present invention, since a plurality of pesticide preparations are supported on a single porous granular material, knitting does not occur and uniform application can be achieved.

[0013] The porous granular material used in the application method of the present invention is not particularly limited as long as it can support an agricultural chemical active ingredient.
For example, there may be mentioned those obtained by granulating mineral powders such as silica sand, pumice stone, calcium carbonate, bentonite, clay, talc, zeolite, diatomaceous earth, perlite, vermiculite and acid clay by extrusion granulation or mixed granulation. By baking, the porous mineral substance particulates evaporate water and low boiling components, thereby forming a more porous structure and imparting a high water absorbing ability (amount of water absorption). The higher the water absorption capacity of the porous granular material is, the better the flowability of the porous granular material carrying the pesticide formulation is.
It is preferably fired, and more preferably fired at a temperature of 1000 ° C. or higher. As a specific example, Isolite CG (trade name, manufactured by Isolite Industry Co., Ltd.), which is a porous ceramics soil improvement material obtained by firing granulated diatomaceous earth at a temperature of 1000 ° C. or higher, may be mentioned.

The particle size of the porous granular material is usually 0.1 to 5 m.
m, preferably 0.3 to 3 mm. The water-absorbable amount of the porous granular material means the maximum amount of water that can be absorbed without substantially deteriorating the fluidity of the porous granular material.
In order to improve the flowability of the porous granular material carrying the pesticide formulation, it is preferable that the porous granular material has a larger water-absorbable amount. Further, in order to more uniformly carry the pesticide formulation on the porous granules, as long as the flowability of the porous granules carrying the pesticide formulation is good, the water absorption capacity of the porous granules is small. It is more preferable. This is because if the amount of water that can be absorbed by the porous granular material is too large, it is locally absorbed and carried. Therefore, the water-absorbable amount of the porous granular material is usually 0.1 to 100 parts by weight, preferably 0.5 to 50 parts by weight, and more preferably 10 to 100 parts by weight based on 100 parts by weight of the porous granular material. To 50 parts by weight, more preferably 15 to
50 parts by weight, most preferably 20 to 50 parts by weight.

To support the pesticide formulation on the porous granules, 1) dilute a liquid or a water-dispersible solid pesticide formulation containing an active ingredient of the pesticide as an active ingredient with water and dilute the diluted solution. Preparation and then mixing the diluent and porous granules; or 2) mixing a porous pesticide with a liquid pesticide formulation containing a pesticidally active ingredient as an active ingredient. is there. In order to ensure the fluidity of the porous granular material carrying the pesticide formulation, in the method 1), the sum of the weight of the water used for diluting the pesticide formulation and the weight of the pesticide formulation carried is It is necessary to reduce the amount of water that can be absorbed (the weight) of the granular material. In the method 2), it is necessary that the weight of the pesticide preparation to be carried is not more than the water-absorbable amount (weight) of the porous granular material.

As a specific example of the method for supporting the agricultural chemical formulation on the porous granular material, for example, the porous granular material is charged into a stirring vessel such as a concrete mixer, and the agricultural chemical formulation is stirred while the porous granular material is stirred. There is a method in which a water-diluted liquid or a liquid pesticide formulation is dropped or sprayed and uniformly carried. The mixing ratio of the porous granular material carrying the pesticide formulation is as follows:
Usually, the amount is 0.1 to 50 parts by weight of the pesticide formulation and 0 to 50 parts by weight of water with respect to 100 parts by weight of the porous granular material. The porous granular material carrying the pesticide formulation used in the application method of the present invention is suitable for spraying on non-agricultural land such as a green space, a garden, a parking lot, a graveyard, a tank yard, and a factory, and various annual Weeds, perennial weeds, various pests, various diseases and the like can be effectively controlled. In the application method of the present invention, the porous granular material carrying the pesticide formulation is usually 500 g to 100 kg per 10 ares, preferably 1 kg to 5 kg.
0 kg is applied.

Hereinafter, specific examples of the application method of the present invention will be described. In addition, “parts” means parts by weight. [Application Example 1] Isolite CG (trade name, Isolite Industry)
Co., Ltd., calcined product of porous granular material obtained by granulating diatomaceous earth) 50

By dropping or spraying the diluted solution diluted in the part,
An acephate-containing granulate is obtained. This is sprayed in a planting plant using a manual granulator at a rate of 3 to 6 kg per 10 ares to control pests. [Application Example 2] A diluent obtained by diluting 0.4 part of Bethrosin water dispersible powder (containing 58% of Bethrosin) with 15 parts of water using a pressurized spray was placed in a concrete mixer, and 50 parts of Isolite CG was stirred and stirred. By spraying, a bethrosin-containing granular material is obtained. 50-per 10 ares
Spray at a rate of 65 kg to control weeds in the parking lot. [Application Example 3] 50 parts of Isolite CG is put into a concrete mixer, and while stirring, 0.4 parts of Besrosin wettable powder (containing 58% vesrodin) and 0.5 parts of acephate wettable powder (containing 50% of acephate) are mixed with water. By spraying 15 parts of the diluted liquid using a pressurized spray,
A granulate containing bethrosin and acephate is obtained. This is 50-65k per 10 ares using an electric granulator.
