KR-20260063742-A - Pesticide composition for controlling forest pests containing edible plants as the main ingredient

Abstract

The present invention relates to a forest pest insecticide composition comprising a complex extract of Korean mint, Perilla frutescens, wild sesame, and fennel as an active ingredient. Specifically, when the complex extract of Korean mint, Perilla frutescens, wild sesame, and fennel is mixed with fermented alcohol and an emulsifier and sprayed, it has high insecticidal power against forest pests such as the American white moth and the convex thrips. Since it uses edible plants as the main ingredient, it utilizes eco-friendly materials and can be used safely and effectively in the agricultural field.

Description

Pesticide composition for controlling forest pests containing edible plants as the main ingredient The present invention relates to an insecticide composition comprising edible plant ingredients as active ingredients, and more specifically, to an insecticide composition comprising *Pimpinella koreana*, *Perilla frutescens*, *Siberian sesame*, and *Fennel* as active ingredients. Insecticides are chemicals effective in killing insects that are harmful to humans or crops. The demand for insecticides, used to control pests during crop cultivation and to improve crop productivity, continues to be sustained. Chemical synthetic pesticides, which have been conventionally used until now, have significantly contributed to increasing agricultural productivity by controlling diseases and pests that occur during crop cultivation. However, the excessive use of chemically synthesized pesticides has caused soil and water pollution and contaminates greenhouse cultivation environments, posing a threat to the health of farmers. Furthermore, residual chemical components in agricultural products grown using chemical synthetic pesticides are highly toxic to the human body, leading consumers to prefer safe food grown without the use of synthetic pesticides. In addition, interest in agricultural safety issues and sustainable agriculture through soil environment preservation has recently been increasing. Under these circumstances, organic farming is rapidly expanding globally, and the same situation applies to household pesticides, insect repellents, animal pesticides, and disinfection pesticides. In addition, natural insecticides used in organic farming are harmless to humans, livestock, fish, and shellfish, and have the advantage of posing no risk of environmental pollution or ecosystem disturbance, which is why much research is being conducted on them recently. The use of natural insecticides derived from plant extracts has the advantage of ensuring safety by allowing for the sustainable preservation of the soil environment and eliminating the risk of pesticide residues on crops. Depending on how the insecticide acts on and disperses within the treated plant, insecticides can be classified into residual insecticides, which have a localized effect, and systemic insecticides, which are sprayed onto the soil in granular form and provide long-term control by allowing the active ingredients to be absorbed by the plant. Examples of pesticide components extracted from plants or minerals and used for pest control include pyrethrin (extracted from pyrethrum), rotenone (extracted from the roots of derris), nicotine (extracted from tobacco), and arsenic (isolated from arsenic), which are widely known. Related patents include Registered Patent No. 10-1221735 “Natural insecticide composition containing Coptis japonica extract and clove extract as active ingredients,” Registered Patent No. 10-1620002 “Natural insecticide composition,” and Registered Patent No. 10-1482764 “Natural insecticide composition containing plant extract as active ingredients.” To date, natural insecticides for forest pests such as the American white moth and the convex thrips have not been developed. The present invention will be described in more detail below through examples. These examples are intended to explain the present invention more specifically, and the scope of the present invention is not limited to these examples. Example 1. Preparation process of complex extract of Korean mint, Perilla frutescens, Japanese sesame, and fennel. After exposing Korean mint, Perilla frutescens, Pulsatilla koreana, and fennel to sunlight for about 5 hours, they were dried using a hot air dryer at 50°C for about 5 to 6 hours. Subsequently, 100g of Korean mint, Perilla frutescens, Pulsatilla koreana, and fennel were placed in 500ml of fermented alcohol (95% ethanol), either individually or together, and crushed and steeped for at least 3 weeks to obtain a stock extract of 2,400 ppm. The obtained stock extract was diluted 50 times (48 ppm) and used. Example 2. Method for spraying a complex extract of Korean mint, Perilla frutescens, Japanese sesame, and fennel and a fogging agent A 50-fold diluted solution of a complex extract of *Chamaesa pumila*, *Perilla frutescens*, *Sargassum fusiforme*, and *Fennel*, fermented alcohol, and an emulsifier were mixed with a fogging agent and used. A solution of glycerin and water was used as the fogging agent; since a small fogging machine was used in the experiment, the glycerin and water were mixed in a weight ratio of 1:3 for the experiment. The mixture of the insecticide composition and the fogging agent was sprayed onto the white-eared moth and the convex thrips using a heated fogging method with a small fogging machine. After 30 minutes had passed since spraying the mixture of the insecticide composition and the fogging agent using the heated fogging method, the insecticidal activity of the insecticide composition containing the complex
