Description
본 발명은 작물의 재배 시 문제되는 잡초들을 효과적으로 방제할 수 있는 식물 유래 천연 추출물을 포함하는 잡초 방제용 조성물 및 이의 사용하는 잡초 방제 방법에 관한 것이다. The present invention relates to a weed control composition comprising a plant-derived natural extract that can effectively control the weeds in question during the cultivation of crops, and to a weed control method thereof.
잡초는 작물재배에서 광, 양분, 수분 등의 경합 및 탈취하여 생산성과 상품성을 크게 저하시키거나 병해충의 매개, 농작업을 곤란하게 하는 주요 방제 대상이다. 잡초는 장소, 계절, 환경 등에 상관없이 연중 발생하며, 방제에 많은 노력과 비용이 소요된다. 지금까지는 잡초방제를 위하여 여러 가지 유기합성 제초제를 사용해 왔으나, 합성 제초제의 과도한 사용으로 저항성을 갖는 개체가 증대되었을 뿐만 아니라, 환경에 대한 유해성과 잔류 독성이 사회적인 문제로 지적되고 있다. 최근, 농산물의 안전성이 보장되는 친환경 농산물에 대하여 급증하는 수요와, 환경 생태계 보존을 위한 사회적 요구에 부응하고자, 합성농약을 사용하지 않고 잡초를 방제하기 위한 연구가 활발하게 진행되고 있다. Weeds are the main targets for the control of crops, nutrients, moisture, etc., which deteriorate productivity and commerciality, or make pests difficult and agricultural work difficult. Weeds occur throughout the year regardless of location, season, environment, etc., and they require a lot of effort and expense to control them. Until now, various organic synthetic herbicides have been used for weed control, but excessive use of synthetic herbicides has increased the number of resistant individuals, as well as environmental hazards and residual toxicity are pointed out as social problems. Recently, in order to meet the rapidly increasing demand for environmentally friendly agricultural products, which guarantee the safety of agricultural products, and social demands for the preservation of environmental ecosystems, research is being actively conducted to control weeds without using synthetic pesticides.

실시예Example 1. 식물 정유의 준비 1. Preparation of Plant Essential Oils
본 발명에 사용된 정향유, 파인오일, 아니스오일 및 윈터그린오일은 수증기 증류법(distillation method)으로 식물정유를 추출 및 시판하는 물질이며 삼영식품원료공업주식회사(대한민국)에서 구입하여 사용하였다. Clove oil, pine oil, anise oil and winter green oil used in the present invention are substances that extract and market plant essential oils by a steam distillation method and were used by Samyoung Food Raw Materials Co., Ltd. (Korea).
상기에서 준비한 정유 성분은 다양한 희석 배율로 희석하여 제초 효과를 시험하였으며, 각 희석 배율에 따른 식물 정유의 함량을 아래의 표 1에 나타내었다.The essential oil components prepared above were tested for herbicidal effect by diluting at various dilution ratios, and the contents of plant essential oils according to each dilution ratio are shown in Table 1 below.
[표 1] TABLE 1
실시예Example 2. 2. 식물정유Plant essential oil 단제Sweet 및 혼합제의 처리농도별 잡초방제효과 Weed Control Effects by Treatment Concentrations
2.1. 잡초방제 2.1. Weed control 달관평가Evaluation
상기 실시예 1에서 준비된 식물 정유를 사용하여 농업용, 특히 친환경 잡초 방제용으로서의 유용성 여부를 평가하였다. The plant essential oils prepared in Example 1 were used to evaluate their usefulness as agricultural, in particular, environmentally friendly weed control.
우선, 식물정유의 조합 및 희석 배수에 따른 잡초방제효과를 평가하기 위하여 바랭이(화본과잡초), 및 명아주(광엽잡초)에 대한 약효를 조사 및 비교 평가하였다. 바랭이, 명아주 등은 대표적인 밭잡초로 잡초방제효과를 검정하기에 적합한 것으로 선택된 것이다. 대조약제로는 그라목손
식물정유 단제 및 혼합제는 처리농도를 달리하여 100㎖/㎡ 수준의 처리물량으로 경엽처리 한 후, 달관 평가하여 그 결과를 하기의 표 2에 나타내었다. Plant essential oils and mixtures were treated with foliage at 100 ml / m2 level at different treatment concentrations, and then evaluated by the crown tube. The results are shown in Table 2 below.
[표 2] TABLE 2
그 결과, 상기 표 2에서 확인하실 수 있는 바와 같이, 한 가지 성분만 단제로서 사용된 경우의 최고농도 처리구보다 3 성분 및 4 성분 혼합제의 최저농도 처리구의 잡초방제 효과가 월등히 우수하다는 것을 알 수 있다. 특히, 정향유+파인오일+아니스오일, 또는 정향유+파인오일+아니스오일+윈터그린오일에서 잡초 방제 효과가 매우 우수하였으며, 특히 정향유+파인오일+아니스오일+윈터그린오일의 4 성분 혼합제의 경우 처리농도에 상관없이 잡초가 완전고사하여 혼합조합의 시너지 효 과가 뚜렷한 것으로 나타났다.As a result, as can be seen in Table 2, it can be seen that the weed control effect of the lowest concentration treatment of the three-component and four-component mixing agent is superior to the highest concentration treatment when only one component is used as a single agent. . In particular, weed control effect was very excellent in clove oil + pine oil + anise oil, or clove oil + pine oil + anise oil + winter green oil, especially in the four-component mixture of clove oil + pine oil + anise oil + winter green oil. Regardless of whether weeds were completely killed, the synergistic effects of the mixed combinations were apparent.
2.2. 잡초방제 상호작용효과 2.2. Weed Control Interaction Effects
식물 정유의 단독 성분을 함유하는 단제 및 3 가지 이상을 함유하는 혼합제 처리를 병행하여 혼합제의 반응 기대값을 구하기 위하여 Colby method (한점화, 구자옥, 천상욱, 권오도. 1992. 주요 논 잡초종에 대한 제초제간의 상호작용효과 해석연구. 한국잡초학회지 12(2):144~157, Kwon, Oh-Yeon, Yong-Woong Kwon. 1997.

Cyhalofop-butyl과 Metamifop 혼합처리에 의한 화본과 잡초 방제효과 증진. 한국잡초학회지 27(2):91~101)를 적용하였으며, 기대값 계산은 아래와 같다. In order to obtain the reaction expectation value of the blending agent in parallel with the treatment of a single ingredient containing a plant essential oil and a blending agent containing three or more, the Colby method (Han-Jung, Gu Ja-Ok, Chun Sang-Wook, Kwon Do-Do. 1992. Herbicides for the main paddy field weeds Korean Journal of Weed Journal 12 (2): 144 ~ 157, Kwon, Oh-Yeon, Yong-Woong Kwon. 1997. Antagonistic Interaction between Quinclorac and Bensulfuron-methyl on Growth of the Rice Plants.KJWS 17 ( 3): 288 ~ 294, Jin Suk Kim, Jung Sup Choi, Kwang Yeon Cho 2007. Enhancement of plant and weed control effects by mixing Cyhalofop-butyl and Metamifop, Korean Journal of Weed Journal 27 (2): 91 ~ 101) It looks like this:
Y1 +2=Y1+Y2-(Y1× Y2)/100 --- (식 1)Y 1 +2 = Y 1 + Y 2- (Y 1 × Y 2 ) / 100 --- (Equation 1)
위 식에서 Y1 +2는 물질(식물정유) A, B를 혼합했을 때의 반응 기대값이며, Y1과 Y2는 두 물질을 각각 단제 처리했을 때의 방제가이다. 기대값(Expected Value)과 관찰값(Observed Value)을 서로 비교하여 관찰값이 기대값보다 크면 상승효과(Synergistic effect)가 있고 그 반대의 경우에는 길항효과(Antagonistic effect)가 있는 것으로 해석하였다. 관찰값이 기대값보다 큰 경우 그 차이가 클수록 상승효과가 크다고 할 수 있으며, 80~90% 정도의 안전한 방제가 이루어지면서 상호작용력도 크고 가능한 한 약량이 적게 소모되는 조합을 가장 효과적인 조합으 로 판단하였다. In the above formula, Y 1 +2 is the expected reaction value when the substances (plant essential oil) A and B are mixed, and Y 1 and Y 2 are the control values when the two substances are separately treated. Expected Value and Observed Value were compared with each other and interpreted as having a synergistic effect when the observed value was larger than the expected value and antagonistic effect on the contrary. If the observed value is larger than the expected value, the greater the difference, the greater the synergistic effect.The most effective combination is the combination with the high interaction power and the smallest amount of medicine, with safe control of 80 ~ 90%. It was.
상기 식 1에 의하여 얻어진 결과를 기초로 한 식물정유 단제 및 혼합제의 상호작용 효과 (Colby method)를 아래의 표 3에 나타내었다.Based on the results obtained by the above formula 1, the interaction effect of the plant essential oil alone and the mixing agent (Colby method) is shown in Table 3 below.
[표 3]TABLE 3
<*CLO;정향유, PIN;파인오일, ANI;아니스오일, WIN;윈터그린오일> <* CLO; Clove oil, PIN; Fine oil, ANI; Anise oil, WIN; Winter green oil>
상기 표 3에서 알 수 있는 바와 같이, 식물정유 혼합처리의 방제가(관찰값)는 각 단제 방제가에 의한 기대값보다 현저하게 높은 것으로 나타나서, 혼합 처리시의 상승효과가 확인되었다. 특히 4중 혼합제의 경우 각 단제의 최저희석농도 조합으로 방제가가 크게 증대되어 상승효과가 뚜렷하였다. As can be seen from Table 3, the control value (observation value) of the plant essential oil mixing treatment was found to be significantly higher than the expected value by each single control value, the synergistic effect of the mixing treatment was confirmed. In particular, in the case of the quadruple mixture, the combination of the lowest dilution concentrations of each single agent significantly increased the control value, and the synergistic effect was obvious.
실시예Example 3. 3. 식물정유Plant essential oil 단제Sweet 및 혼합제의 잡초방제 지속효과 Effect of the Weed Control of Infant and Mixtures
상기 실시예 2에서 사용된 식물정유 단제 및 혼합제의 잡초방제 지속효과를 비교하기 위하여, 단제의 최고희석 농도, 및 혼합제의 최저희석 농도에서의 지속효과를 측정하여 비교하였다. 식물정유의 처리물량 100㎖/㎡ 수준으로 경엽 처리 한 후, 발생초종 전체를 달관평가하였다. 발생된 주요 밭 잡초는 화본과 잡초인 바랭 이, 강아지풀, 돌피 등이었고, 광엽잡초는 명아주, 여뀌, 깨풀, 메꽃, 환삼덩굴, 쇠비름, 개비름, 괭이밥, 가막살이, 털별꽃아재비, 닭의장풀, 망초, 석류풀 등 다양하게 발생하였다. 또한 사초과 및 기타 잡초는 참방동사니, 금방동사니, 쇠뜨기 등이 발생하였다. In order to compare the weed control lasting effects of the plant essential oils and the mixing agent used in Example 2, it was compared by measuring the lasting effect at the highest dilution concentration and the minimum dilution concentration of the mixture. After the leaves were treated to 100 ml / m 2 of plant essential oil, the entire seedlings were evaluated. The main field weeds were flower and weed varieties, dog grass, dolphy, etc. It occurred in various ways such as grass. In addition, the herbaceous and other weeds were found to be true worms, swells, and horseshoe.
처리 후 1, 5, 15, 30일째 무처리 대비 초종별 및 전체초종에 대한 방제 지속 효과를 조사하여, 그 결과를 아래의 표 4에 나타내었다On the 1st, 5th, 15th and 30th day after treatment, the effect of sustained control on herbicides and total herbicides was investigated, and the results are shown in Table 4 below.
[표 4] TABLE 4
상기 표 4에 나타낸 바와 같이, 단제 처리구에서는 처리 15일 이후 급격한 효과 저조를 보였으며, 혼합제 처리구에서는 그 정도가 대체로 완만하여 효과가 지속되었다. 특히 정향유+파인오일+아니스오일+윈터그린오일의 4중 혼합제의 경우 처리 후 30일 까지도 85.0% 수준 나타나 잡초방제 지속효과가 매우 우수한 것으로 나타났다. As shown in Table 4, the single treatment treatment showed a drastic effect after 15 days of treatment, and in the mixed treatment treatment, the degree was generally mild and the effect continued. In particular, quadruple mixtures of clove oil + pine oil + anise oil + winter green oil were 85.0% up to 30 days after treatment, indicating a very good sustaining effect of weed control.
이상의 결과를 통해 볼 때, 식물정유 3중 혼합제 (예컨대, 정향유+파인오일+ 아니스오일) 및 4중 혼합제 (정향유+파인오일+아니스오일+윈터그린오일)는 단제 또는 2중 혼합제보다 저농도의 혼합조성물로 잡초방제 효과 및 그의 지속효과가 뛰어나 친환경 잡초 방제제로서 최적의 조성물로 판단되며, 유기농산물에 재배에 적합한 생물적 방제제로 개발될 수 있을 것으로 기대된다. Based on the above results, the plant essential oil triple mixture (eg clove oil + pine oil + anise oil) and the quadruple mixture (clove oil + pine oil + anise oil + winter green oil) have a lower concentration than the single or double mixture. It is considered to be an optimal composition as an eco-friendly weed control agent because of its excellent weed control effect and its continuous effect, and is expected to be developed as a biological control agent suitable for cultivation in organic products.
