KR-102960071-B1 - Insecticide Composition Comprising Natural Essential Oil Derived from a Plant

Abstract

The present invention provides an insecticide composition comprising 30 to 50 parts by weight of an emulsion emulsifier and 10 to 20 parts by weight of a nanocarrier, based on 100 parts by weight of cinnamon oil. The insecticide composition containing plant-derived natural essential oils according to the present invention prevents the delayed onset of effect during pest control even when using natural substances derived from plants as biopesticides, and enables the pest control effect to be equivalent to or greater than that of chemical pesticides, thereby contributing to the maintenance of sustainable agriculture through the effective control of soil-borne diseases and pests in continuous cropping.

Description

Insecticide Composition Comprising Natural Essential Oil Derived from a Plant The present invention relates to an insecticide composition comprising a plant-derived natural essential oil, and more specifically, to an insecticide composition comprising a plant-derived natural essential oil that provides sufficient control power compared to chemical pesticides with management standards below the economic damage density of pests, even while using natural substances derived from plants. The application for the present invention was filed by the applicant with the support of Gyeonggi-do, and the information regarding the research and development project that supported the present invention is acknowledged as follows. [Research and development projects that supported this invention] [Project ID] D2222023 (Enter PMS project number) [Ministry Name] Gyeonggi-do [Specialized Research Management Agency] Gyeonggi Economic & Science Promotion Agency [Research Project Name] Corporate-led General [Research Project Title] Development of Natural Raw Material Convergence Biomaterials for Simultaneous Control of Soil Parasitic Nematodes and Diseases, and Development of Novel Biopesticide Formulations [Contribution Rate] 0.2 [Principal Research Institution] 2M Bio Co., Ltd. [Research Period] 2022-07-01 ~ 2023-06-30 Watermelon, a representative summer fruit in Korea, is an important crop that accounts for 11% of the production value of fruit and vegetables (Major Statistics of the Ministry of Agriculture, Food and Rural Affairs, 2019), but it is very susceptible to pests and diseases caused by continuous cropping, so it must be cultivated by grafting onto pumpkins or gourds as rootstocks. The reason for using the above grafted watermelon seedlings is that they are resistant to vine wilt and nematodes. However, there is currently an increasing trend of acute wilt disease and nematode damage, and as the number of fields requiring crop rotation or fallow periods increases, there are problems such as a decline in the sugar content and quality of watermelons due to the influence of rootstocks like gourds or pumpkins, and a decrease in farm income due to rising seed costs. Therefore, it is necessary to develop biopesticides for soil control of continuous cropping disorders to increase farm income and produce high-quality watermelons sustainably. In addition, the major pests and diseases affecting watermelons are root-knot nematodes (Meloidogyne spp.) and wilt disease (Fusarium oxysporum, Schl. sp. niveum). Nematodes are the cause of reduced crop yields in greenhouse cultivation, with an annual loss of approximately 250 billion won, and it is estimated that about 70 billion won is spent on nematicides used to control them. Meanwhile, there are four species of nematodes that damage crops in Korea: M. arenaria, M. hapla, M. incognita, and M. Javanica. Among these, M. incognita is found in watermelon fields. As watermelon cultivation becomes larger, year-round, and mass-produced, damage from root-knot nematodes is on the rise. However, there is no effective control method for this, so the application of fumigants and fallow periods are necessary. Additionally, there are currently no control agents available for Manchurian wilt disease, which is one of the reasons why watermelon seedlings cannot be grown, making it urgent to develop control measures. The Philippines produces 8,645,749 tons of bananas annually, with about 80% of this production coming from Davao, Northern Mindanao, and Bukidnon, accounting for 87.5% of Asia's total banana exports (4.51 million tons) and about 20% of the world's banana exports. In particular, regarding the status of overseas nematodes and wilt diseases, M. incognita and M. arenaria are widely distributed wherever bananas and plantains grow in the Philippines. For example, DE WAELE reported that 82% of root samples collected in the Davao region were infected with root-knot nematodes, with an average of 3,500 nematodes per 100g of root, and that root galls were widely formed. In addition, if bananas are infected with root-knot nematodes, root damage occurs, which can lead to severe crop yield loss (YANG, Xiujuan, et al.). These nematodes are one of the causes of transmission of soilborne bacteria, and nematode infection has been reported to weaken plant resistance to plant pathogens, making them particularly vulnerable to Panama disease (OKA, Yuji, et al.). Therefore, effective control of these nematodes is urgently needed in banana plantations. Meanwhile, root invasion wounds caused by the proboscises of soil-parasitic nematodes facilitate the invasion of soil-pathogenic fungi into plant tissues, resulting in a high correlation between nematode damage and the incidence of wilt disease caused by soil-pathogenic fungi. In particular, the aforementioned soil-parasitic nematodes and wilt disease have the characteristic of causing damage by originating in the soil, which is the underground part of crops. To overc
