Description

[0001]
BACKGROUND OF THE INVENTION
The present invention has a breathable inner lid, and a container in which a certain amount of contents are discharged when the inner lid is removed, particularly a container suitable for a biopesticide formulation that can easily carry out pest control with a biopesticide. And a pesticide in a container in which a living organism (hereinafter referred to as an agrochemical organism) effective for controlling pests of agricultural and horticultural crops is contained in the container.
[0002]
[Prior art]
Various containers have been proposed so far that use a non-breathable or non-breathable lid for the outer lid or outer lid and inner lid, and remove the lid when in use to discharge a certain amount of pesticides such as insecticides. ing. Various proposals have also been made regarding a method for breeding biological pesticides and containers therefor. For example, JP-A-3-108433 can be mentioned regarding a container suitable for the growth of small natural enemy mites, and a method for mass propagation and storage or transportation of mites using this container. Japanese Patent Application Laid-Open No. 6-125687 can be cited as an example of a storage container and a method for extracting turnip mites that can efficiently extract minute natural enemy mites.
[0003]
[Problems to be solved by the invention]
However, from the viewpoint of storage stability of the medicine in the container, it is preferable to use a non-breathable or non-breathable container for both the outer lid and the inner lid from the viewpoint of the storage stability of the medicine in the container. It was general and was not suitable as a storage spray container for biological pesticides. Proliferation methods for biological pesticides and containers proposed therefor are considered suitable for the growth and extraction of organisms such as turnip mites, but efficiently and uniformly agrochemical organisms, which are natural enemies, on actual crops. Difficult to spray.
An object of the present invention is to provide a container suitable for efficiently applying a certain amount of an agrochemical organism, for example, acarid mite, to a crop, and the agricultural chemical contained in the container, which can store and transport the agrochemical organism alive.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present inventors have produced a container comprising a breathable outer lid, a breathable inner lid, and a container body, and the outer lid has a function of breathing and dispensing a certain amount of the preparation. I made a hole to make it. In other words, during transportation, air passes through the hole in the outer lid by sealing the air-permeable inner lid between the outer lid and the container body, but agrochemical organisms such as red mites, etc. Because the pores for obtaining air permeability are dense, they cannot escape to the outside of the container. During application, once the outer lid is opened and the breathable inner lid is removed, only the outer lid is attached to the container body again, and the container is turned 180 degrees and shaken, so that the biological pesticide can be removed from the hole in the outer lid. We found that it could be sprayed quantitatively with a single swing. In addition, the same effect can be achieved by providing a mechanism for dispensing a certain amount of the preparation at the opening of the container body instead of the outer lid.
[0005]
In addition, as a result of investigating whether or not a certain amount of biological pesticide can be sprayed from the outer lid hole of the container for biological pesticide of the present invention, an arbitrary amount of biological pesticide can be obtained by changing the size of the outer lid hole. It was found that it can be sprinkled with good reproducibility and can be efficiently applied to a large amount of crops. Even if a similar mechanism is provided at the opening of the container body, the same effect can be achieved.
[0006]
Accordingly, the present invention relates to the following (1) to (8).
(1) An outer lid, an inner lid, and a container main body having an opening at the top, and the outer lid and the inner lid can be attached to and detached from the opening of the container main body. And a container for biopesticides, wherein the inner lid is made of a material having air permeability,
(2) The container according to (1), wherein the size of the fine hole (gap) for ventilation of the inner lid is a size capable of preventing escape of the agrochemical organism,
(3) The container according to (1) above, wherein the inner lid of the container is a breathable nonwoven fabric (hereinafter referred to as the breathable nonwoven fabric).
(4) The container according to (3) above, wherein the inner lid of the container is a breathable nonwoven fabric made of polypropylene,
(5) The container according to (3) or (4), wherein the basis weight of the breathable nonwoven fabric is in the range of 40 to 200 g / m ² .
(6) The container according to (3) or (5) above, wherein the thickness of the breathable nonwoven fabric is in the range of 0.3 mm to 1.2 mm.
(7) A biopesticide in which the agrochemical organism, the bulking agent and / or the food of the organism coexist in the container described in (1) to (6) above,
(8) The biopesticide according to the above (7), wherein the agrochemical organism is a red mite.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to FIG.
Reference numeral 1 denotes an outer lid of a biopesticide container, which is not particularly limited in material. For example, it is made of plastic or the like, and can be detachably connected to the container body by means such as screw holes or fitting. The connecting means is not particularly limited as long as the outer lid is connected so as to be integrated with the container body so that the contents do not spill out through the breathable inner lid. In some cases, the connecting means does not necessarily have to be integrated with the outer lid, and may be connected to each other by a connecting tool or the like independent of both of them in the container body.
[0008]
2 is a hole opened in the outer lid in order to give air permeability and a function to squeeze the formulation. In the drawing, the shape of the hole is circular and the number of holes is one. In the case where the content is a biopesticide using bran or the like as a carrier , the size is, for example, 8 mm to 30 mm in diameter, preferably 10 mm to 20 mm, and more preferably 10 mm to 15 mm. Usually, since the shape and size of the hole of the outer lid vary depending on the contents, it cannot be said unconditionally, but the circular shape is optimal. The size is appropriately adjusted according to the amount discharged by one swing. For example, depending on the contents, a circular hole having a diameter of, for example, 1 mm to 30 mm, preferably about 2 mm to 20 mm, more preferably 3 mm to 15 mm is formed on the outer lid. Or those with a plurality of openings are preferred. However, the shape, size, since Suto more different contents, the preliminary drawing board testing, it is preferably determined to allow discharge a constant amount required. For example, although depending on the size of the outer lid, etc., a plurality of holes of about 2 mm to 10 mm, for example, 2 to 10 or 10 or more holes may be formed if they are small holes. In addition, when a mechanism capable of discharging a certain amount of the formulation is provided at the opening of the container body, the hole in the outer lid may simply have a function of achieving air permeability.
[0009]
3 is a breathable inner lid, and the material is not particularly limited. However, when considering biological pesticides, a sufficient amount of air for the organism inside can be supplied through the hole in the outer lid and the breathable inner lid. In addition to having a certain level of air permeability, the size of the air holes should be able to prevent escape of the organism inside. As such a material, for example, a plastic having good moldability (polypropylene or the like) can be used. The inner lid is preferably of a size that completely covers the opening of the container body and that is in close contact with the opening. For example, at a basis weight breathable nonwoven ^{40g / m 2 ~200g / m 2} , those preferably ^{70g / m 2 ~150g / m 2} , it was cut to the same as the outer lid and the container body mouth size It is. In some cases, the inner lid may be integrated with the outer lid, for example, when a mechanism capable of discharging a certain amount of the preparation is provided at the opening of the container body.
[0010]
4 is a main body of a biopesticide container, and there are no restrictions on the material, shape, size, etc., as long as it can accommodate the target object such as biopesticide and the opening 6 can be connected to the outer lid 1. Absent. For example, it is a plastic container of 500 ml capacity, for example, and the upper opening 6 can be connected to the outer lid 1 by connecting means such as screwing. In addition, when providing a mechanism that can discharge a certain amount of the formulation in the opening, the size of the hole in the opening of the container body may be adjusted, or a hole that allows a certain amount to be discharged in the opening. A new lid may be provided.
[0011]
5 is a biological pesticide stored in the container. As the biopesticide accommodated in the container of the present invention, a product prepared by blending a pesticide organism with a bulking agent and / or a pesticide organism bait is usually used. For example, in the case of formulations containing phytoseiid mites, grown phytoseiid mites such a bran such as medium (bulking agent), it may be filled to the present invention the container it as a formulation. The bulking agent may be appropriately selected from those used as bulking agents for agricultural chemicals according to the type of agrochemical organism, the type of formulation, and the like. Pesticide organisms are effective for controlling pests of agricultural and horticultural crops, for example, caribbean mites, sand bugs, crabs, etc. Examples thereof include, but are not limited to, bran, vermiculite, cork and the like.
[0012]
The container for biological agrochemicals passes through the hole 2 of the outer lid 1 and the breathable inner lid 3 by sealing the breathable inner lid 3 between the outer lid 1 and the opening of the container body 4 during transportation. Although air passes, microbes for agricultural chemicals such as red mites cannot escape out of the container because the pores of the breathable inner lid are dense.
When spraying the stored biopesticides, after removing the outer lid 1 and the breathable inner lid 3 from the container body 4 and removing the breathable inner lid 3, only the outer lid 1 is connected to the container body opening again. By turning the container upside down and swinging out, the biological pesticide can be quantitatively sprayed from the hole 2 of the outer lid. In the case where a mechanism capable of discharging a metered amount of the formulation to the opening of the container body may be sprayed while removing the outer lid 1 and the inner lid 3. The amount applied varies depending on the type of biopesticide and the concentration of the pesticide organism in the preparation, but it is usually in the range of 0.05 g to 1 g, preferably about 0.1 g to 0.5 g, with one fall. Range. The amount of spraying can be changed by appropriately adjusting the size and number of the holes 2 in the outer lid.
[0013]

Example: Hole diameter 14mm 61,300 52,200 85.2
Comparative Example 1 61,300 13,000 21.2
[0023]
The example container having a hole in the outer lid had a survival rate of 80% or more even after being left for 4 days, but the survival rate of the mites was extremely low in the container of Comparative Example 1 in which no air was vented.
[0024]
Test example 4
In Example 1, the biopesticide (with the container of the present invention) having a hole diameter of 12 mm in the outer lid and the biopesticide of Comparative Examples 2 and 3 (with the containers of each comparative example) were placed indoors at room temperature. It was allowed to stand for 4 days, and the number of burdock mites surviving in the container after being left standing was examined and compared with the burdock mites escaping from the outer lid or the junction between the container body and the inner lid.

[0026]
Although the thing of the Example had a survival rate of 80% or more even after being left for 4 days, in Comparative Example 2, the basis weight of the nonwoven fabric of the inner lid material was low (material density was low), and escaped outside the container. I confirmed a lot of ticks. In Comparative Example 3, the basis weight of the inner lid material is high (the material density is high), so there are no mites that escape, but the air permeability is poor and the survival rate of mites is reduced.
[0027]
【The invention's effect】
By using the biopesticide container of the present invention, it is possible to maintain a high number of surviving animals in the biopesticide such as turnip mites during transportation, and to effectively and accurately apply natural enemy pesticides to large quantities of crops. did it.
