JPH0499704A - Production of insecticidal/germicidal agent - Google Patents

Abstract

PURPOSE:To provide the title agent of expanded application range, comprising dry powder of leaf tobacco plant or its extract and pyrolignous acid or the like and, where needed, insecticide, germicide, herbicide, phytohormones. CONSTITUTION:For example, the stems and leaves of leaf tobacco are dried into fine powder, which is then incorporated with an appropriate amount of shell fossil fine powder followed by pyrolignous acid or the like. The resulting mixture is kneaded to a clay form and processed into granules 2-3mm in size, which are then dried, thus obtaining the objective insecticidal/germicidal agent. The present agent may be further incorporated with at least one kind of material selected from insecticides, germicides, herbicides, phytohormones etc. The present agent is especially useful as an insecticidal/germicidal/herbicidal agent in soil in paddy fields, being usable e.g. for controlling the larvae of rice stink bug. Also, use of the extract from the dry powder of said leaf tobacco plants will provide an insecticidal/germicidal agent for leaf application. The present agent has no concern for any environmental pollution.

Description

[Detailed description of the invention]

"Purpose of the Invention" [Industrial Field of Application 1] The present invention utilizes a dried powder of a single-leaf tobacco plant mixed with wood vinegar and bamboo vinegar produced in the process of manufacturing charcoal and bamboo charcoal. This invention relates to a method for producing insecticides and fungicides that can be used to produce insecticides and fungicides.

[Conventional technology and its problems] Conventionally, leaf tobacco cannot be cultivated freely because it is a product exclusively produced by contract cultivation. Therefore, the current situation is that the use of this is not considered. However, regarding the stem after harvesting the leaves,
It is suitable for use in compost, etc. as a corrosive fertilizer. Furthermore, wood vinegar and bamboo vinegar are only used as preservatives. [Problems to be Solved by the Invention] Therefore, at present, the above-mentioned tobacco leaves and wood vinegar solution or bamboo vinegar solution have not been mixed to enhance their synergistic effect. In view of the current situation, the present invention was developed to solve the above problems, and its purpose is to dry the stems and leaves of leaf tobacco into a fine powder, and then add wood vinegar and bamboo vinegar to it. The purpose is to mix them and process them into granules or granules to create and utilize new substances with high insecticidal and bactericidal properties. "Structure of the Invention" [Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is produced by mixing a dried leaf tobacco plant with one or both of wood vinegar and bamboo vinegar. Another invention is a method for producing an insecticide/bactericide, which is characterized in that it is produced by mixing an extract extracted from a dried powder of a leaf tobacco plant with one or both of wood vinegar solution and bamboo vinegar solution. This is a unique method for producing insecticides and fungicides. To give a specific example, tobacco stems and leaves are processed into dry fine powder, an appropriate amount of fine shell fossil powder is added to this, wood vinegar solution and bamboo vinegar solution are added, mixed well, kneaded into a clay-like form, and this is made into granules. The soil sterilizing and soil insecticidal substances were prepared by adjusting and processing the particles into particles of about 2 to 3 m in size and drying them. [Function 1] Therefore, in the present invention, by using an ilW mixture of dried tobacco leaf powder, wood vinegar solution, and bamboo vinegar solution, it is highly effective to use as a soil insecticide, sterilization, and herbicidal substance, especially in paddy fields. It becomes possible to provide substances. In addition, by using an adjusted mixture of the extract extracted from the dried powder of leaf tobacco plants and wood vinegar solution and bamboo vinegar solution in the above-mentioned configuration, an insecticidal and bactericidal substance for foliar spraying on plants can be provided. becomes possible. [Examples] Examples of the present invention will be specifically described below. ■A mixture of 1 part dried and finely powdered leaf tobacco stems and 1 part finely powdered shellfish fossil by weight, and an appropriate amount of bamboo vinegar solution for growth. A material with a high soil insecticidal effect can be produced by kneading it into a clay-like form, adjusting it into granules, and drying the resulting product, which has an insecticidal and bactericidal function without affecting the soil. The table below shows the test results of the survival rate (%) of rice stink bug larvae when the insecticide of this example was sprayed on soil. ■Dry the leaf tobacco stems and grind them into powder using a mixer.
0g is boiled in 200cc of distilled water, and this nicotine-based extract is mixed with an equal amount of bamboo vinegar, and an appropriate amount of a spreading agent is added to this to create a solution that has a bactericidal effect. It is possible to manufacture materials with high quality. The table below shows the frequency of appearance of sweet potato lesions as a result of spraying the fungicide in this example. "Effects of the Invention" As is clear from the above, according to the present invention, tobacco stems and leaves are dried and pulverized. Materials produced by adjusting and mixing bamboo vinegar and wood vinegar have made it possible to expand the range of uses beyond the conventional use of single substances due to the synergistic effect of tobacco stem and leaf powder, bamboo vinegar and wood vinegar, and are currently a decisive factor. It can be used to exterminate the larvae of rice stink bugs, which are lacking in water. Furthermore, since this substance is an organic substance, there is no fear of environmental damage, and it has excellent effects such as being optimal as a highly useful material for producing healthy agricultural products.
