Abstract
Description
본 발명은 천연에 존재하는 노난산(nonanoic acid)를 이용하여 식물 기생성 선충을 방제하기 위한 살선충 조성물에 관한 것이다.The present invention relates to nematicidal compositions for controlling plant parasitic nematodes using nonanoic acid present in nature.
종래에는 농업해충용 방제제로 화학농약을 많이 이용하였으나, 사용량이 늘어나면서 동물과 인체에 농약성분이 다량 축적되는 것을 알게 되었고, 그 부메랑 효과에 의한 환경파괴로 인해 생태계가 점점 심각해져 가고 있음을 알게 되었다. Conventionally, chemical pesticides have been used a lot as pest control agents for agricultural pests, but as the amount of use increases, it has been found that a large amount of pesticides are accumulated in animals and the human body, and the ecosystem is getting worse due to the environmental destruction caused by the boomerang effect. .
즉, 종래의 화학성분의 농약은 농약성분의 85∼90%가 대기, 토양, 수계에 살포되어 지속적으로 환경을 파괴시키고, 병해충에 대한 내성 및 저항성이 커지고, 인체에 해를 끼치는 문제가 있다. That is, the conventional chemical pesticides have a problem that 85 to 90% of the pesticides are sprayed on the atmosphere, soil, water system to continuously destroy the environment, the resistance and resistance to pests increases, and harm to the human body.
예를 들어, 소나무 재선충은 소나무(Pinus densiflora), 해송(P. thunbergii), 마미송(P. massoniana), 유구송(P. luchuensis), 대만 이엽송(P. taiwanensis) 등에 병징을 일으켜 소나무를 죽게 한다. 우리나라에서는 1988년에 처음으로 이 선충에 의한 피해 발생이 확인된 이래, 피해가 계속 확산되고 있으며 현재는 울산, 포항, 경주 등 전국 47개 시군구에 발생하여 큰 피해를 주고 있다. 소나무 재선충에 감염된 소나무와 해송은 대부분 감염된 지 불과 3개월 이내에 완전히 고사되는데, 매개충인 솔수염하늘소는 고사목이나 쇠약목에 산란을 하고, 부화한 유충이 고사목내에서 발육, 월동한 후에 이듬해 5월부터 성충으로 우화한다. 현재 우리나라의 소나무재선충병 방제는 주로 감염된 소나무를 벌채한 후, 메탐소디움액제로 훈증처리하거나, 소나무 재선충을 매개하는 솔수염하늘소 성충의 후식을 방지하기 위하여 메프유제를 항공 살포하고 있다. 유기합성농약의 효과는 우수했지만 계속적인 사용과 무분별한 남용으로 인해 해충 천적의 감소, 저항성 발달, 잠재 해충의 대발생 그리고 사람과 가축에 대한 독성을 유발하는 문제점이 발생하고 있다.For example, pine re-nematodes can cause pine trees (Pinus densiflora), P. thunbergii, P. massoniana, P. luchuensis, and P. taiwanensis in Taiwan. To die. Since the damage caused by this nematode was confirmed in Korea for the first time in 1988, the damage has continued to spread and is now occurring in 47 cities and counties in Ulsan, Pohang and Gyeongju, causing great damage. Most pines and pines infected with pine re-nematodes are completely killed within only 3 months of infection.The beetle Beethoven, which is a mediator, spawns on dead trees or bark, and after hatching larvae develops and winters in May, the following year Fable to adult. Currently, the control of pine reptiles in Korea is mainly done by harvesting the infected pine trees, fumigation with methamsodium solution, or by air spraying muff emulsion to prevent the erosion of adult male pine needles that mediate pine re-nematodes. The effectiveness of organic synthetic pesticides has been excellent, but the use of pesticides has resulted in reduced pest natural enemies, resistance development, the development of potential pests, and toxicity to humans and livestock.
따라서, 최근 이러한 문제를 해결하기 위한 방안으로 환경 친화적이고 인체나 가축에 대한 독성이 낮은 물질을 해충 방제제로 이용하려는 연구가 이루어지고 있다. Therefore, in order to solve such a problem, researches on using environmentally friendly materials having low toxicity to humans or livestock as pest control agents have been made.
예를 들어, 특허문헌 1에서는 살선충 활성을 가지는 살선충제의 유효성분으로 양파, 계피, 정향, 티트리, 세신, 유향, 베이, 레몬그레스 및 스퍼민트로 이루어진 정유의 군에서 선택되는 하나 또는 2종 이상의 정유를 포함하는 살선충 조성물을 개시하고 있다. 특허문헌 2에서는 산내(Kaempferia galanga) 및 팔각회향(Illicium verum) 중에서 선택된 1종 이상의 추출물을 포함하는 살선충제을 개시하고 있다. 또한, 특허문헌 2에서는 아바멕틴 유제, 에마멕틴 벤조에이트 유제, 포스치아제이트 액제, 이미다클로프리드 유제, 페니트로치온 유제에서 선택된 적어도 1종 이상의 살충제와, 상기 살충제와 함께 작용하여 살선충 효과를 발휘하는 주 석산을 함유하는 살선충제를 개시하고 있다.For example, in Patent Document 1, one or two selected from the group of essential oils consisting of onion, cinnamon, cloves, tea tree, sessin, frankincense, bay, lemongrass, and spermin as active ingredients of nematicides having nematicidal activity. A nematicid composition comprising at least one essential oil is disclosed. Patent Document 2 discloses nematicides comprising at least one extract selected from the acid (Kaempferia galanga) and octagonal fennel (Illicium verum). In Patent Document 2, at least one pesticide selected from abamectin emulsion, emamectin benzoate emulsion, phosphitate solution, imidacloprid emulsion, and phenytrothion emulsion, together with the insecticide, exhibits an nematicide effect. A nematicide containing stannic acid is disclosed.
그러나, 이러한 생물적 방제제는 화학 농약에 비하여 방제효과가 매우 낮아 작물재배 농가는 화학농약을 선호하는 경향이 있다. However, these biocontrol agents have a very low control effect compared to chemical pesticides, so crop cultivators tend to prefer chemical pesticides.

이하 본 발명을 좀 더 구체적으로 살펴보면 다음과 같다. Looking at the present invention in more detail as follows.
본 발명은 노난산을 이용한 식물 기생성 선충을 방제하는 살선충 조성물에 관한 것이다. 본 발명의 노난산을 이용한 살선충 조성물은 노난산과 계면활성제를 혼합하여 제조된 살선충 조성물이다. 상기 살선충 조성물에 있어서, 상기 노난 산의 함량은 10∼90중량%이며, 10중량% 미만이면 살선충 효과가 떨어지고, 90중량%를 초과하면 상대적으로 계면활성제가 적게 첨가되어 수용화가 어려운 단점이 있다. The present invention relates to nematicide compositions for controlling plant parasitic nematodes using nonanoic acid. The nematicidal composition using nonanoic acid of the present invention is a nematicidal composition prepared by mixing nonanoic acid and a surfactant. In the nematicidal composition, the content of the nonanoic acid is 10 to 90% by weight, and less than 10% by weight of the nematicidal effect is lowered, and when it exceeds 90% by weight, relatively few surfactants are added so that it is difficult to receive water. have.
본 발명에 따르면, 기존에 알려진 생물학적 방제능력이 뛰어난 물질을 더욱 포함할 수 있다. 이러한 식물 기생성 선충을 방제하는 살선충 조성물로 녹차추출물(카테킨 및 탄닌 함유), 솔잎추출물(탄닌 및 클로로필 함유), 계피산(cinnamic acid), 계피유(cinnamon oil) 또는 이들의 임의의 혼합물 등이 있다. According to the present invention, it may further include a material known to have excellent biological control ability. Nematode compositions for controlling such plant parasitic nematodes include green tea extract (containing catechin and tannin), pine needle extract (containing tannin and chlorophyll), cinnamic acid, cinnamon oil, or any mixture thereof. .
상기 계피산은 톨루발삼이나 페루발삼 속에 벤질에스테르로 존재하는 색깔과 냄새가 없는 결정체로 된 산이고, 계피유는 제과, 식품향료로 사용하는 녹나무과 식물 Cinnamomum cassia Blume 또는 C. zeylanicum Nees의 수피를 수증기 증류하여 얻은 정유이다. 상기 계피산은 유리형, 또는 알칼리 또는 알칼리토금속의 염 형태인 것이 바람직하고, 특히 알칼리 또는 알칼리토금속의 칼륨염인 것이 더욱 바람직하다. The cinnamic acid is a color and odorless crystals present as benzyl ester in toluvalsam or perubalsam, and cinnamon oil is steam distilled from the bark of Cinnamomum cassia Blume or C. zeylanicum Nees, which is used as a confectionery and food flavor. It is an essential oil obtained. The cinnamic acid is preferably in the form of a free or salt form of an alkali or alkaline earth metal, more preferably in particular a potassium salt of an alkali or alkaline earth metal.
상기 노난산은 대상 선충의 방제 효과 및 경제성 등의 이유에 따라 살선충 성분을 혼합하여 사용할 수 있다. 상기 노난산과 살선충 성분의 혼합비는 중량비로 1 : 1 ∼ 1 : 0.5인 것이 바람직하다. 이때 노난산을 1 : 1 미만으로 혼합하면 노난산의 살충 효과가 떨어지고, 살선충 성분을 0.5 미만으로 첨가하면 첨가 의미가 없어진다. The nonanoic acid may be used by mixing nematicidal components according to the control effect and economical efficiency of the target nematode. It is preferable that the mixing ratio of the said nonanoic acid and nematicide component is 1: 1: 1: 0.5 by weight ratio. At this time, if the nonanoic acid is mixed at less than 1: 1, the insecticidal effect of the nonanoic acid is lowered, and if the nematicidal component is added at less than 0.5, the meaning of addition is lost.
본 발명의 살선충 조성물의 주요 성분인 노난산은 9개의 탄소를 가진 지방산으로, 일반적으로 펠라르곤산(pelargonic acid)으로 불린다. 상기 노난산은 자연 환경에서 자연적으로 발생하며, 음식첨가물에서도 발견할 수 있다. 상기 노난산은 토양에서 낮은 농도로 자연적으로 발생되고, 미생물에 의해 매우 빠르게 분해되어 물질대사 경로가 만들어진다. 노난산이 자연 발생되는 음식첨가물로는 포도, 치즈, 및 우유(10∼400 ppm) 등이 있다. 또한, 자연환경에서 콩, 오렌지, 완두콩, 담배, 감자 등에서도 발생된다. Nonanoic acid, which is the main component of the nematicidal composition of the present invention, is a fatty acid having nine carbons, generally referred to as pelargonic acid. The nonanoic acid occurs naturally in a natural environment and can be found in food additives. The nonanoic acid is naturally occurring in the soil at low concentrations and is degraded very quickly by microorganisms to create metabolic pathways. Examples of food additives in which nonanoic acid occurs naturally include grapes, cheese, and milk (10 to 400 ppm). In addition, it occurs in beans, oranges, peas, tobacco, potatoes in the natural environment.
또한, 사과에 20∼320 ppb의 노난산이 함유되어 있으며, 낮은 농도로 과수(배, 사과)에 처리할 경우 품질향상 및 수량 증대의 효과를 보인다. In addition, 20-320 ppb of nonanoic acid is contained in apples, and when treated in fruit trees (pears, apples) at low concentrations, the quality and yield are increased.
이러한 노난산은 제초제(예를 들어, 한국 특허출원 제2002-7001870호 참조), 또는 치주질환제(예를 들어, 한국 등록특허 제10-1947370호 참조) 등으로 사용된바 있으나, 살선충 효과를 보고한 문헌은 없다. Such nonanoic acid has been used as a herbicide (see, for example, Korean Patent Application No. 2002-7001870), or periodontal disease agent (see, for example, Korean Patent Registration No. 10-1947370), etc. No literature reported this.
본 발명에 따르면, 선별한 노난산을 이용하여 살충효과가 나타나고 희석 시 물리적 변화가 없는 계면활성제를 찾기 위해 많은 시행착오를 겪으며 연구를 해오던 끝에, 약제 제조시 노난산이 10중량% 이상, 바람직하게는 60중량% 이상부터 85중량%까지 함유되었을 때 높은 살충효과를 나타냄을 알 수 있었다. According to the present invention, after using the selected nonanoic acid and having undergone a lot of trial and error to find a surfactant that shows the insecticidal effect and does not have a physical change during dilution, nonanoic acid is more than 10% by weight, preferably For example, it can be seen that the insecticide exhibits a high insecticidal effect when contained in an amount of 60 wt% or more to 85 wt%.
