It has only obtained a passive insect repellent effect for a relatively short time compared to the time of seeding or transplantation. In addition, the conventional insect repellent sheet is made of a polymer material, and therefore has poor water solubility and ultraviolet ray decomposability, but has durability, and is difficult to dispose of, including incineration. there were.

[0003]

[Problems to be solved by the present invention] The problems to be solved are, firstly, the ability of fast-acting insect repellent / insect repellent and slow-acting insect repellent.
A pest control sheet for cultivation, which has both insect repelling ability and can be plowed, disposable and incinerated,
In addition, a pest control sheet for cultivation, which is excellent in light-shielding properties, heat retention and laying workability,
Fourth, to provide a cultivation pest control sheet having a pest control ability in soil, and fourthly, to provide a cultivation method capable of cultivating while performing pest control stepwise and efficiently using the pest control sheet. .

[0004]

In order to achieve the above object, the present invention provides a pest control sheet for cultivation, wherein the sheet body is a cultivated pest control sheet comprising a sheet made of paper. A microcapsule comprising a water-soluble or UV-decomposable member and containing any insect repellent and / or insect repellent agent in the same capsule. And the rapid drug effect by the volatile drug and the slow drug effect by the drug in the microcapsule after the water dissolution or ultraviolet decomposition of the microcapsule are exerted with time. It is characterized by having.
Further, in the pest control sheet for cultivation of the present invention, the pest control sheet for cultivation of a multilayer structure comprising a water-soluble or ultraviolet-decomposable member having the property that each layer does not generate toxic gas even when incinerated, wherein the multilayer structure A microcapsule composed of a water-soluble or ultraviolet-decomposable member, and a fast-acting layer in which the body contains any highly volatile insect repellent and / or insect repellent and is formed so as to exhibit a fast-acting drug effect. The capsule is characterized in that it has a slow-acting layer formed so that any insect repellent and / or insect repellent is encapsulated in the capsule and exerts a slow-acting drug effect. . Further, in the pest control sheet for cultivation of the present invention, the multilayer structure has a three-layer structure of the above-mentioned quick-acting layer on the front side, the above-mentioned slow-acting layer on the back side, and a paper base layer below this slow-acting layer. There is a feature.
Further, in the pest control sheet for cultivation of the present invention, the multilayer structure includes the above-mentioned quick-acting layer on the front side, the above-mentioned slow-acting layer on the back side, a paper base layer below this slow-acting layer, and a layer below the base layer. A four-layer structure with the quick-action layer or the slow-effect layer on the side. In the cultivation method using the pest control sheet for cultivation according to the present invention, the pest control sheet is laid or buried in the soil on the planting surface, and the volatile pest control and / or a quick-acting agent using a pesticide chemical is used. The first pest control stage in which the effect is exerted, and before and after the rapid drug effect disappears, the microcapsule dissolves in water or decomposes by ultraviolet rays, thereby causing the insecticide and / or pesticide drug in the capsule to have a slow drug effect. And the second pest control stage in which is exhibited is continuously cultivated.

[0005] In the present invention, the correlation between the drug effect of the volatile drug and the drug in the microcapsule is such that a quick drug effect is first exhibited by the volatile drug, and before and after the effect is lost. The microcapsules are dissolved or decomposed, so that there is a time lag at which the effect of the encapsulated drug, that is, the delayed drug effect is exhibited. Multilayer structure, water-soluble or ultraviolet-decomposable members that do not generate toxic gas even when incinerated where microcapsules are formed, include known water-soluble members that dissolve in water, such as oblate. And a known ultraviolet-decomposable member having a property of decomposing by ultraviolet rays. As the relatively volatile insect repellent or insect repellent exhibiting the above-mentioned quick-acting drug effect, morning glory seeds, extracts from marigold root, known insect repellents such as camphor, pyrethrum and mint Known insect repellents such as components and extracts of bittersweet wormwood are exemplified. Insect repellent and / or encapsulated in microcapsules
Or, as the insect repellent, the above-mentioned relatively volatile insect repellent or insect repellent may be used, or a known insect repellent such as ordinary camphor or herb extract, a known insect repellent such as pyrethrum, or bitterworm may be used. It may be an insect repellent. These insect repellent and / or insect repellent drugs can be changed according to the type of pest, and both layers may be the same drug, or different layers of drugs may be used to exert different drug effects. good.
Further, the number of layers of the multilayer structure in the present invention is arbitrary,
The combination of the fast-acting layer and the slow-acting layer is optional,
Further, the sheet body and the multilayer structure may have a mode in which holes for seeds or seedlings are formed. As the sheet body and the base layer, for example, it can be plowed or crushed so as not to become a waste that leads to environmental destruction, can be reduced to nature, is highly light-shielding, suppresses germination of weeds, and even contacts with seedlings It is possible to use a paper sheet that does not cause seedling burning and is excellent in heat retention and that is of a soil temperature control type and is useful for facility horticulture in summer. At the same time, good workability during laying is ensured.
