Description

[Detailed Description of the Invention] This invention is the result of efforts made in stevia cultivation since 1972. Stevia has been studied to date as a sweetener extracted from a naturally sweet plant native to Paraguay in South America.

Over the past 15 years, we have repeatedly conducted cultivation tests on stevia and found that the yield has never been reduced due to pest damage. Also, when I looked at the wild plants around me, I found out that some of them continue to live without being eaten by insects. - From a numerical standpoint, it can be said that plants that are less susceptible to damage from external enemies, such as stevia, have a relatively low proliferation rate, while plants that are more susceptible to damage from external enemies have a higher proliferation rate. In other words, it is a typical example of crops that have been improved by humans and are easily damaged by insects. Based on this, the aim is to utilize extracts from plants that are original and resistant to attack by insects, thereby repelling pests and increasing the functional activity of crops, thereby realizing pesticide-free agriculture.

(Industrial Application Fields) A1 The concentrated liquid of the present invention is diluted and sprayed on the leaves of crops to protect the crops from pests.It does not kill insects (pests/natural enemies), but has a repellent effect on pests. demonstrate.

B. A synergistic effect is observed by mixing various concentrates.
Plant component extracts are absorbed quickly by foliar spraying, and root development is promoted by flooding the roots with water.
The leaves become more glossy and grow vigorously. It repels pests in rice, field crops, forestry, lawns, fruit trees, vegetables, flowers, etc., and activates the functions of each crop.

In the agricultural field, ground powder of Stevia stems, leaves (sweetener extraction residue) and roots is used as feed for livestock and soil improvement by reducing organic matter to the soil.

(Prior art) A. Pesticides are used to kill pests, but useful natural enemies are also killed, and toxic residues are added to agricultural products and soil, causing water pollution.

B. Like pesticides, most plant activators are chemically synthesized.

First, the stems and leaves of stevia (sweet extract residue) were thrown away.

(Problems to be solved by the invention) A. Repelling pests using plant extracts.In principle, a balance is maintained in the natural animal and plant world. Given the current situation where the balance has been disturbed due to human intervention, we would like to reduce the use of chemically synthesized pesticides and restore the polluted environment to nature and produce healthy agricultural products.

2. Activation of crop functions using plant extracts. All crops contain the nutrients (in the cotyledons) necessary for them to grow into leaves and stand on their own. Excessive fertilization is a cause of functional disorders.The aim is to supply plant extracts to crops while repelling pests so that the cotyledons of crops are not eaten by pests.

1. Reuse of Stevia stems, roots, and leaves (sweet extraction residue).

Use as livestock feed and soil improvement. Unlike the past era of livestock farming, today we are in the era of mechanized agriculture, and the soil is becoming desolate and uninhabitable for the ``worms'' who strive to produce a rich overflow9.
By applying it to such soil as an organic matter, it improves the soil structure, returns ingredients including the center of Stevia stems, leaves, and roots to the soil, and reduces the number of nematodes in the soil.

The present invention attempts to solve these problems.

(Means for Solving the Problems) Since 1972, we have been conducting Stevia cultivation tests, and through trial and error, we have arrived at the present invention.

A. Pest repellent effect due to plant extracts. Stevia is 1
It is a plant that has been used as a sweet plant by the natives of Paraguay since the 6th century, but has continued to live in the wilderness without being improved as a crop until today. Stevia, which has coexisted with many wild plants and has continued to exist to this day without being eaten up by insects, is thought to have possessed some self-defense substances. During the 15 years of cultivation, I have never suffered damage from pests. From this, we suspected that Stevia contained components that repelled these pests, and succeeded in extracting the components from Stevia stems, leaves, and roots, and creating a concentrated Stevia component extract. .It seems that there are likes and dislikes in ingredients and smell depending on the type of pest.

Numerous ingredients, including stevia's unique sweetener (stevioside) as its main ingredient, as well as wild species of plants that are not damaged by pests in each region, such as comfrey, hamboufu, and stevia.
We made a concentrated solution of extracting components from Udo, Eleuthero, Horsetail, Hekudami, Kumazasa, Tambobo, etc.

(2) Activation of crop functions with plant ingredient extracts, foliar spraying of crops, and root irrigation tests; Stevia stems, roots, and leaves (sweet extraction residue) were made into dried coarse powder.

(Effect) 1,000- of component extract (1) extracted from Stevia
Foliar spraying of 1,500 times diluted solution. Stevia component extract (
1) 80% other plant extracts (2) (3) (
4) Foliar spraying and root irrigation of a 1.000 to 1.500 times diluted solution of a 20% mixture of (5) (6) (7) (8) (9).

Application of dry ground powder of Stevia stems, roots, and leaves (sweet extract residue) for livestock feed and soil improvement.

(Example) Examples of the present invention will be described below.

A, Stevia component extract (1) i, ooo~1,
Foliar spraying of 500 times diluted solution. Paddy rice, soybeans, adzuki beans, peas, potatoes, strawberries, radish, carrots, Chinese cabbage, body vegetables, spinach, white turnips, tahsai honeysuckle, celery, eggplants, tomatoes, kirari, melons, apples, saffron leaves, blueberries, flowers - Foliar spraying for potted plants, root irrigation, and seed-grown plants should be sprayed first at the time of germination (cotyledons), then twice every 15 days or so.
Sprayed ~3 times. Root irrigation should be done 3 days after transplanting or planting.

B. 1.000% of a mixture of 80% Stevia component extract (1) and 20% of other plant extracts (2) to (9).
- 1.500 times dilution was carried out in the same manner as in Example (A).

First, when the dried coarse powder of Stevia stems, roots, and leaves (residue from sweetener extraction) is compressed, the mixture has a suitable consistency and powder, making it a good feed for livestock. Furthermore, it is applied as soil improvement organic matter.

(Effect of the invention) A. 1,000 to 1,500 stevia component concentrate
Double dilution. 1.000-1,500 by mixing 80% Stevia component concentrate with 20% other plant component concentrates.
Germination (cotyledons) of each crop in the previous example as a 2-fold dilution
If sprayed occasionally, pests will not come near, and even if adult insects fly to lay eggs, they will fly away soon, making it highly effective in repelling pests. At the time of germination, the weather was sunny and dry (and Kiboshimaru I and ground fleas (ground fleas) ate the cotyledons and caused severe damage, but there was no damage when this diluted solution was sprayed. Also, adults and larvae were collected and diluted. When the liquid was sprayed on the leaves and placed in an observation bottle for observation, the oilseed insects moved from the cluster of new leaves and moved to the edge of the bottle where the liquid was not applied.Other adult insects The larvae do not eat a single bite, and they move 4 to 5 times more than normal.Since there are no unsprayed leaves, aphids and other larvae are 5 to 5 times more active than normal.
The insects died in seven days, but the adult chimney beetles and the Japanese red beetles were still alive, although their motility had weakened. In this way, it showed a repellent effect on pests.

Cotyledons at the seedling stage are like breast milk for babies. The cotyledons sprayed with the diluted solution are not damaged by feeding, so the rooting and leaf development are excellent. It showed plant functional activation effects, such as increasing the color and luster of leaves unique to each crop. This not only has a pest repellent effect, but since the diluted solution is a pure vegetable ingredient, it is absorbed directly from the leaves.Furthermore, by watering the roots with the diluted solution, absorption from the roots increases and the number of roots increases in the non-flooded area. It was more than three times that of the previous year. This is thought to be due to the mutual effect of repelling pests and being a direct nutrient source for crops. There is no need to worry about pesticide residue.

This diluted liquid is not dangerous even if licked by humans, so it can realize pesticide-free cultivation of foods that are eaten raw, such as fresh vegetables and fruits.

B. Stevia leaves were discarded after the sweetener (stevioside) was extracted, and the stems were incinerated, but analysis of these revealed that they are highly nutritious as feed for livestock, and that the sweetness in the leaves that remained when the leaves were shed was found. It has been found that livestock love to eat it.

Mix the stems and leaves (sweet extract residue) and grind When powdered and compressed, it became a feed that livestock liked.

C. When the same as above (a) is applied to soil, it supplements organic matter, improves the problem of continuous cropping of crops, and suppresses soil nematodes.

The present invention provides pest repellent effects, crop functional activation effects,
The effectiveness of livestock feed and soil improvement can be measured.
