Definitions
- the present invention relates to a pesticide composition containing a component for reducing a pesticide active ingredient remaining in a crop, and a pesticide residue decomposer.
- pesticides are organic compounds that contain characteristic chemical structures in their molecules that determine their action characteristics. Many pesticides are highly toxic to humans as well as pests and viruses. Pesticides also have a strong influence on and destroy the ecological environment of farmland and surroundings: ⁇ . Therefore, the molecular structure of pesticides is usually designed so that the spontaneous progress of the pesticide progresses over time after application. However, the spontaneous decomposition of such pesticides generally progresses slowly and abruptly.
- the present invention was conceived under such circumstances, and an agricultural chemical composition capable of adequately exhibiting the effects of agricultural chemicals and sufficiently reducing the amount of residual agricultural chemicals;
- the purpose is to provide.
- an agricultural chemical composition contains a pesticidal active ingredient and powdered metal-modified apatite in which a part of metal atoms contained in the apatite crystal structure is a photocatalytic metal atom.
- the photocatalytic metal atom refers to a metal atom that can function as a photocatalytic center in an oxide state.
- the apatite constituting the basic skeleton can be represented by the following general formula.
- CaHAP calcium hydroxyapatite in which A in the above formula is calcium (Ca), B is phosphorus (P), and X is a hydroxyl group (1 OH), ie, Ca 10 (PO 4 ) 6 (OH) 2 .
- CaHAP Calcium hydroxyapatite
- CaHAP is highly adsorbable because it easily exchanges ions with both cations and anions, and is particularly excellent in adsorbing organic substances. For this reason, CaHAP has been actively researching applied technologies in a wide range of fields, such as adsorption jj for chromatography, iridescence sensors, and ion exchangers. CaHAP is a main component of living hard tissues such as animal teeth and bones.

(In), iron (F e) and the like.
- some oxides of these metals have a photocatalytic property as a metal oxide semiconductor.
- electrons in the valence band generally transition to the conduction band by absorbing light having energy corresponding to the band gap between the valence band and the conduction band. Then, holes are generated in the valence band. Electrons in the conduction band have a property of moving to a substance adsorbed on the surface of the photocatalytic semiconductor, and the adsorbed substance can be reduced.
- the holes in the valence band have the property of removing electrons from the substance adsorbed on the surface of the photocatalytic semiconductor, whereby the adsorbed substance can be oxidized.
- titanium oxide (T i ⁇ 2 ) having a photocatalytic function electrons that have transitioned to the conduction band reduce oxygen in the air to generate superoxide aeon ( ⁇ ⁇ 2 —).
- the holes generated in the valence band oxidize the water adsorbed on the titanium oxide surface to form hydroxyradicanole (-().
- Hydroxy radicals have a very strong acidity. Therefore, when, for example, an organic substance is adsorbed to the photocatalytic titanium oxide, the organic substance may be eventually converted into water and carbon dioxide by the action of a hydroxyl radical.

If the ratio is less than 3 mo 1%, the catalyst site with a small amount of active pesticide adsorbed on the excess adsorption site may not be sufficiently treated. In some cases, the utility is not fully exhibited.

Therefore, when the pesticide composition is sprayed on a crop, Ti-CaHAP adheres to the crop and soil together with the pesticide active ingredient. Thereafter, the pesticidal active ingredient gradually decomposes naturally while exhibiting pesticidal activity. In addition, pesticidal active ingredients are also released by Ti-CaHAP, for example, under daylight conditions.

That is, the pesticide composition of the present invention has a higher degree of freedom with respect to the time of application than the conventional pesticide composition, and is therefore suitable for appropriately exerting the effect of the pesticide active ingredient.
- Ti—CaHAP has a CaHAP-like basic skeleton. Therefore, Ti-Ca HAP, which has finished its role of decomposing pesticide residues, can be decomposed by bacteria that inhabit the soil after flowing into the soil due to rain or the like. Therefore, in this embodiment, Even if the pesticide composition is used more than once on the same arable land, the pesticide residue will not eventually accumulate in the soil. Also, since Ti-CaHAP contains calcium phosphate !, it is decomposed to act as phosphate fertilizer and calcium fertilizer for soil. In contrast, photocatalytic oxidized titanium is not degraded by soil systems.
- a pesticide composition containing photocatalytic titanium oxide is used more than once in the same arable land as a pesticide residue composition, the pesticide residue accumulates in the soil, and the ecosystem of the soil is adversely affected. In some cases force s put away.
- the Ti-CaHAP particles may be covered with an organic film.
- it is the organic film that undergoes a decomposition action at the coating location under light irradiation conditions. For this reason, the degradation of the pesticidally active component by Ti-CaHAP is inhibited at the coated site.

It can be formed by adsorbing talent. After adsorbing the tree-containing material on the Ti-CaHAP particles, the Ti-CaHAP powder is pulled up from the solvent and dried. Alternatively, the solvent may be evaporated while the Ti-Ca HAP powder is immersed in the solvent.
