The use part of the above-mentioned Sendangsa plant may be any part of the root, the above-ground part (stem, leaf, flower, etc.) or the whole plant. In particular, the use of leaf and stem portions is preferred in terms of efficacy.
In the present invention, the term “Sendangusa plant” includes a plant that has been collected without any treatment, or is cut into pieces or crushed.
In the present invention, “squeezing of Sendangusa plants” refers to the juice of whole plants or parts (for example, only above-ground parts) of “Sendangusa plants”. The juice may be further dried before use.

"Dried product of Sendangsa plant" refers to a product obtained by drying the whole plant or the above-ground part of a Sendangsa plant as follows.
As drying, sun drying or ventilation drying is used. In the latter case, the temperature may be at a level that does not burn, but it is preferably 80 ° C. or lower for safety. In the case of sun drying, it is necessary not to get wet in the middle of drying. As a standard for drying, it is desirable to dry until the water content is 10% or less. You may produce a dry powder by grind | pulverizing after drying.

"Extract of Sendangsa plant" is extracted from the above-mentioned live plant of Sendangsa plant, juice of Sendangsa plant or dried product thereof, or dried product of Sendangsa plant using a suitable solvent. .
Examples of the solvent include water, organic solvents such as methanol, ethanol, methyl acetate, ethyl acetate, ethylene glycol, and butylene glycol, and mixed solvents thereof.
Furthermore, you may use what was extracted by adding water or a hydrous solvent at normal temperature or under heating. As an extraction method, for example, it is possible to obtain an extract by dipping and leaving still, or using an extraction device such as a Soxhlet extractor. The temperature at the time of extraction can be usually about room temperature to about the boiling point. The extraction time depends on the temperature and the solvent, but when extraction is performed at room temperature to about boiling point, it can be performed over a range of about 1 to 300 hours.
When the juice or extract is used after being dried, it may be used as a dried product or a dry powder by spray drying, freeze drying or the like. Moreover, you may mix and use a small amount of paste components as an adhesive agent in drying.

When using a plant of the genus Sedangusa as a dried product or dry powder, it is preferably added in an amount of 0.1 to 30.0% by mass, more preferably 2.0 to 20.0% by mass, and more preferably 5.0 to 10.0% by mass. Is effective and most preferred. In addition, when using an extract of the plant belonging to the genus Sendanga, it is preferably added in an amount of 0.02 to 5.0% by mass, more preferably 0.1 to 3.0% by mass, and more preferably 1.0 to 1.0% by weight in terms of the dry extract. It is effective and most preferable to use at -2.0 mass%.
Specifically, for example, when using a dry product or dry powder of biden spirosa, 10 g to 3 kg of dry product or dry powder of biden spirosa is mixed and used for 10 kg of soil.
In addition, when using the Sendangsa plant itself or the juice of the Sendangsa plant in the soil, it may be used in an amount that falls within the above range in terms of the dry powder of the Sendangsa plant. For example, 1 kg of bidenspirosa plant corresponds to about 90 to 130 g of dry powder of bidenspirosa, so 100 g to 30 kg of live bidenspirosa plant may be added to 10 kg of soil.

  When the dry powder of bidenspirosa is used directly in plants in liquid or gel form, it is based on the approximate mass of the whole plant or plant part selected from the group consisting of flowers, seeds, leaves, stems, roots or fruits. It is desirable to add so that the dry powder of biden spirosa will be 1.0-10 mass%. Moreover, when using the extract of a biden spirosa, it is desirable to use 0.01-1.0 mass% with respect to the mass of a plant in conversion to the extraction dry powder of a biden spirosa.

  In the case of gelation, examples of the gelling agent include glucomannan, hydroxyethyl cellulose, hydroxymethyl cellulose and the like. The addition amount of the gelling agent may be about 0.1 to 10.0% by mass with respect to the amount of water to be added.

[Production Example 1] Bidden Spirosa Dry Powder Bidden Spirosa cut above ground (1.2Kg), cut into 1-5cm, dried naturally (110g), and crushed to 10-1000 microns.

[Production Example 2] Hot water extract of biden spirosa 50 g dry product of above-ground parts (stems and leaves) of biden spirosa was added to 1,000 g of water, extracted at 80-100 ° C for 4 hours, cooled and filtered to extract hot water. 600 g (2.1% by mass pure content) of the product was obtained.

[Production Example 3] Hot water extract dried product of biden spiroza 100 g of the hot water extract obtained in Production Example 2 was freeze-dried to obtain 2 g of dry powder.

[Production Example 4] Bidenspirosa hot water extract gel 5 g of hydroxyethyl cellulose was added to 100 g of the hot water extract obtained in Production Example 2 to form a gel.

[Example 1] Growing action of radish 2.0%, 5.0%, 10.0%, and 20.0% by weight of the soil obtained in Production Example 1 to which no dry powder of bidenspirosa (BP) was added and the soil, respectively. After planting radish seedlings of the same growth in the soil, the degree of radish growth after 4 months was investigated and summarized in Table 1.
As is clear from Table 1, the radish grown on the soil to which the dry powder of bidenspirosa (BP) was added was promoted for growth and had a good taste. In addition, it was found that the growth of radish depends on the amount of dry powder of biden spirosa.

[Example 3] Action of Fig on Fruit Using the bidenspirosa (BP) hot water extract gel obtained in Production Example 4, the gel was applied to American fig fruit on the same tree at the end of June 2007. We investigated the difference between what was and what was not. American figs are fruitful in early July and are faster and sweeter than Japanese figs. Although it can be applied to all figs, American figs are particularly susceptible to insects and have the disadvantage of decaying quickly. It was tested whether this defect could be eliminated. The results are summarized in Table 3. The reason why the gel is formed is that it is easy to apply and lasts a long time.
More specifically, as the application group and the non-application group, five American fig fruits (average 20 g (approx. 3 cm in length) at the time of application) were selected. The bidenspirosa (BP) hot water extract gel obtained in 1 above was applied once in the amount of 2 to 5 g per one.
American figs from all coated and uncoated groups were harvested on the same day.
As is clear from Table 3, none of the samples coated with the bidenspirosa (BP) hot water extract gel was pested and could be further delayed. On the other hand, in the non-applied group, fig spider mites were attached up to 2-5. Moreover, since the uncoated group was all rotten and could not be eaten, the odor was evaluated.

Table 3: Results until ripeness of American figs

[Example 4] Influence on rose flower The Bidenspirosa (BP) hot water extract obtained in Production Example 2 was sprayed four times at a time from the bud of the rose until it bloomed to test the pest control effect.
More specifically, about 10 g of hot water extract was sprayed to one bud at a time, and it was performed three times until it bloomed.
The results are summarized in Table 4. The pest repellent effect was visually observed. “Good” means that there is no insect pest, and “no effect” means that many aphids have been attached. The state at the time of flowering was also observed visually. “Best” means that the petal has no flaws and flowered cleanly, and “bad” means that the petal has flaws or deformation and has not flowered completely.
As is clear from Table 4, none of the spray-coated bidenspirosa (BP) hot water extract showed aphid repellent effect. On the other hand, all of the non-application groups were aphids and the flower condition was poor.

Table 4: Effects on rose flowers

[Example 5] Effects on Anthurium and Begonia Anthurium and Begonia seedlings were added to the soil containing 1.0 g / kg of the dried bidenspirosa (BP) hot water extract obtained in Production Example 3 and 1 kg of soil. After each planting, the growth of Anthurium and Begonia was investigated for one month.
The growth of Anthurium and Begonia planted in soil with the addition of Biddenspirosa (BP) hot water extract was significantly higher than Anthurium and Begonia planted in soil without any addition. Anthurium and begonia grown in soil to which Bidden Spiroza (BP) hot water extract and dried product was added grew about 2 cm in 7 days and about 10 cm in 1 month. In addition, the leaves became about twice as large in one month (leaf blade). On the other hand, the anthurium and begonia grown in the soil without any additions grew about 1 cm in 7 days and about 5 cm in 1 month. Also, the leaves became about 1.5 times larger in one month (leaf blade).
