Description

오이 덩굴쪼김병 방제용 비병원성 푸사리움 옥시스포럼 4-1 및 그 배양상토제{Nonpathogenic Isolate Fusarium oxysporum 4-1 Showing Cross Protection Against Fusarium Wilt of Cucumber and Its Seedbed Soil Formulation}Nonpathogenic Isolate Fusarium oxysporum 4-1 Showing Cross Protection Against Fusarium Wilt of Cucumber and Its Seedbed Soil Formulation}

본 발명은 오이 덩굴쪼김병 방제용 비병원성 푸사리움 옥시스포럼 4-1, 그 배양방법 및 그 배양상토제에 관한 것이다.The present invention relates to a non-pathogenic Fusarium oxis forum 4-1, cucumber cultivation method for controlling cucumber vine cutting disease, and its culture topological agent.

오이는 연중 소비되는 채소로서 재배작형이 다양하다. 특히, 수요가 많은 여름철 작형에서 덩굴쪼김병이 많이 발생한다. 오이덩굴쪼김병은 오이재배에 있어서 가장 피해가 큰 병의 하나로, 토양전염성이 있으며, 도관병이기 때문에 일단 발생된 후에는 방제가 곤란하고, 방제약제도 거의 없는 실정이다.Cucumbers are vegetables that are consumed year-round, with a variety of crop types. In particular, the vine splitting disease occurs a lot in the summer demand type. Cucumber splitting disease is one of the most damaging diseases in the cultivation of cucumbers, it is contaminated with soil, and because it is a conduit disease, it is difficult to control once it occurs, and there is almost no control medicine.

현재까지 오이덩굴쪼김병의 방제는 주로 저항성 대목을 이용한 접목재배에 의존하고 있는데 이 방법은 품질면에서 오이고유의 맛이 떨어지며, 곡과발생이 많아 상품가치를 낮추고 접목시 노력이 많이 드는 결점이 있다. 또한, 접목재배에서도 장기간 연작하면 덩굴쪼김병이 많이 발생하여 심한 경우에는 재배지 전체가 전멸하는 등의 사례도 발생하고 있어 오이재배에 큰 어려움을 겪고 있다.To date, the control of cucumber slices is mainly dependent on cultivation using resistant wood, and this method has the disadvantages that the taste of cucumber oil decreases in terms of quality, and the product value is high due to the grain and occurrence, and the effort of grafting is high. . In addition, in the cultivation of cultivation for a long period of time, many cases of vine splitting occur, and in severe cases, the entire plantation is wiped out, and thus there is a great difficulty in cucumber cultivation.

한편, 최근에 농약의 부작용에 대한 사회적 관심이 높아지면서 약제방제가 어려운 토양병해에 대하여 토양미생물을 이용한 생물학적 방제방법에 관한 연구가 많이 시도되고 있다. 예를 들면, 자연상태하에서의 치유방법과 유사한 미생물을 이용한 생물적 방제법이 있다. 이러한 방법중의 하나로 식물에 병을 일으키는 병원균 중 병원성이 전혀 없는 비병원성균이나 병원성이 약한 약병원균을 미리 기주식물체에 접종하므로서 기주식물체내에 저항력을 사전에 증진시켜 병을 방제하는 방법에 대한 연구가 활발하다. 이와 같은 방법은 환경오염, 약해, 잔류독성 등의 문제를 야기시키지 않는다는 장점 이외에 그 방제효과가 오래 지속된다는 면에서 매우 바람직한 방제방법으로 평가되고 있다.On the other hand, as the social interest on the side effects of pesticides has recently increased, a lot of researches on biological control methods using soil microorganisms for soil diseases difficult to control drugs. For example, there is a biological control method using a microorganism similar to the healing method in the natural state. As one of these methods, researches on how to control disease by increasing the resistance in the host plant in advance by inoculating the host plant with non-pathogenic bacteria or weak pathogenic bacteria without pathogenicity among the pathogens causing the disease in plants are active. Do. Such a method is evaluated as a very preferable control method in that the control effect is long lasting in addition to the advantage that it does not cause problems such as environmental pollution, weakness, residual toxicity.

따라서, 본 발명자는 오이덩굴쪼김병의 병원균과 아주 유사하나 식물에 병을 일으키지 않는 미생물을 찾고자 하였다. 그 결과 오이덩굴쪼김병 방제효과가 탁월하면서도 안정성이 있어 농가실용화가 가능한 비병원성 미생물로서 푸사리움 옥시스포럼 4-1(Fusarium oxysporum 4-1)을 발견하고 그 배양상토제를 제작하여 본 발명을 완성하게 되었다.Thus, the present inventors have sought to find microorganisms that are very similar to the pathogens of cucumber vine cutting disease but do not cause disease in plants. As a result, it was found that Fusarium oxysporum 4-1 as a non-pathogenic microorganism capable of practical use of farms due to excellent and stable control of cucumber vine splitting disease, and produced the culture soil agent to complete the present invention. It became.

또한, 본 발명은 푸사리움 옥시스포럼 4-1을 식물체에 미리 접종하여 줌으로써 식물체에 저항성 병원균에 대한 저항력을 사전에 증진시켜 병을 방제하고자 한다.In addition, the present invention is to inoculate the Fusarium Oxysis Forum 4-1 in advance to the plant to improve the resistance to pathogens resistant to the plant in advance to control the disease.

도 1은 비병원성 푸사리움 옥시스포럼 4-1의 대량증식방법을 나타낸 모식도이다.Figure 1 is a schematic diagram showing the mass growth method of the non-pathogenic Fusarium Oxy Forum 4-1.

본 발명은 오이 덩굴쪼김병 방제용 비병원성 푸사리움 옥시스포럼 4-1, 그 배양방법 및 배양상토제를 제공한다.The present invention provides a non-pathogenic Fusarium Oxysis Forum 4-1, cucumber cultivation method and a culture top soil agent for controlling cucumber vine cutting disease.

또한, 본 발명은 비병원성 푸사리움 옥시스포럼 (Fusarium oxysporum) 4-1 균주를 사용하는 것을 특징으로 하는 오이덩굴쪼김병의 생물학적 방제방법을 제공한다.In addition, the present invention provides a method for biological control of cucumber slices, characterized by using the non-pathogenic Fusarium oxysporum 4-1 strain.

본 발명자는 전국의 부식질이 많은 산에서 그리고 각종 작물이 재배되고 있는 경작지 토양이나, 오이·토마토 등 외견상 아주 건전하게 보이는 식물체에서 오이덩굴쪼김병균(Fusarium oxysporumf.sp.cucumerinum)과 형태적으로 동일한 282개 미생물을 분리하여 실내와 온실시험을 거쳐 오이덩굴쪼김병에 대하여 병을 일으키지 않는 154개 비병원성균을 선발하였다.The present inventors have found the form of Fusarium oxysporum f . Sp . The same 282 microorganisms were isolated and 154 non-pathogenic bacteria that did not cause disease against cucumber vine cutting were selected through indoor and greenhouse tests.

선발된 균주들을 각각 토양배지(모래8:밀기울2)에 접종하여 28℃에서 20일간 배양하여 육묘용상토(부농상토)와 1:1로 혼합하여 포트에 담고 오이종자를 파종하여 30일간 육묘하는 방법으로 비병원성균주를 식물체에 전접종하였다. 오이덩굴쪼김병균을 인공배양하여 병이 다발생하게 조성한 토양에 상기와 같은 방법으로 육묘한 모를 정식하여 재배하면서 병발생 여부를 조사하였다. 그 결과 방제효과가 가장 우수하며 안정적으로 효과가 유지되는 비병원성균주를 선발하였으며, 비병원성 푸사리움 옥시스포럼 4-1라고 명명하고 출원전 상기 미생물을 기탁하였다(기탁번호:KFCC-11161).Each of the selected strains was inoculated in a soil medium (sand 8: bran 2), incubated for 20 days at 28 ° C, mixed 1: 1 with seedling soil (floating soil), put in pots, and sowing cucumber seeds for 30 days. Non-pathogenic strains were pre-inoculated to the plants by the method. Investigation of the disease occurred by raising seedling seedlings in the same manner as the above method in the artificially cultured cucumber creeping pathogenic bacteria. As a result, a non-pathogenic strain was selected which had the best control effect and maintained the stability, named the non-pathogenic Fusarium oxis forum 4-1, and deposited the microorganism before application (Accession No .: KFCC-11161).

비병원성 푸사리움 옥시스포럼 4-1은 오이덩굴쪼김병균과 형태적으로 동일하나, 식물에 병을 일으키지 않는 비병원성균으로서 신규한 것이다.Non-pathogenic Fusarium oxis forum 4-1 is morphologically identical to Cucumber Streptococcus, but is a new non-pathogenic bacterium that does not cause plant disease.

비병원성 푸사리움 옥시스포럼 4-1은 방제효과가 우수하고 지속적으로 효과가 유지될 뿐만 아니라 타작물에도 병을 일으키지 않아 오이덩굴쪼김병 방제용미생물로서 실용화에 적합한 미생물이다.The non-pathogenic Fusarium oxis forum 4-1 is a microorganism suitable for practical use as a microorganism for controlling cucumber vine split disease because it has excellent control effect and sustained effect and does not cause disease in other crops.

비병원성 푸사리움 옥시스포럼 4-1의 분류학적 특성은 하기와 같다.The taxonomic characteristics of the non-pathogenic Fusarium oxis forum 4-1 are as follows.

1. 형태적 성질1. Morphological Properties

비병원성 푸사리움 옥시스포럼 4-1은 불완전균의 일종으로 균사 이외에 분생자와 후막포자를 형성한다. 분생자는 무색, 초생달형으로 격막이 1∼5개의 대형분생포자와 무색, 단세포인 누에모양의 소형분생포자를 형성한다. 특히, 대형분생포자는 격막 1∼5개를 가지며 무색, 초생달형으로 약간 구부러진 것이 특징이며 1격막 포자는 크기가 9∼30×2.0∼5.0㎛이고, 3격막 소형분생포자는 크기가 5∼16×2.0∼4.5㎛이다.Nonpathogenic Fusarium oxis forum 4-1 is an incomplete bacterium that forms conidia and thick spores in addition to mycelia. Conidia are colorless, super crescent-shaped, forming 1 to 5 large conidia of diaphragm and silkworm-like small conidia of colorless and single cell. Particularly, the large conidia have 1 to 5 diaphragms and are colorless and slightly crescently curved. The 1 diaphragm spores have a size of 9 to 30 × 2.0 to 5.0 μm. It is * 2.0-4.5 micrometers.

2. 배양적 성질2. Cultural Properties

감자배지(PDA, Potato Dextrose Agar)상에서는 소형분생포자만을 형성하며 대형분생포자는 거의 형성하지 않는다. 생육적온은 24∼27℃ 부근이며, 4∼38℃ 범위에서 생육한다. pH는 4.5∼5.8부근의 산성조건하에서 생육이 좋다. 일반적으로 푸사리움균과 배양적 특성이 동일하다.On potato medium (PDA, Potato Dextrose Agar) only small conidia are formed and large conidia are rarely formed. The growth temperature is around 24-27 ° C and grows in the range of 4-38 ° C. The pH is good to grow under acidic conditions around 4.5 ~ 5.8. Generally, the culture characteristics are the same as those of Fusarium bacteria.

3. 생리적 성질3. Physiological Properties

비병원성 푸사리움 옥시스포럼 4-1은 단당류로부터 다당류까지 여러종류의 당의 이용이 가능하며 펙틴이나 셀룰로오스도 이용한다. 초산태나 아미노산태 질소는 비병원성 푸사리움 옥시스포럼 4-1의 생육을 촉진하는 것이 많으며 암모니아태 질소는 잘 이용하지 않는다.Non-pathogenic Fusarium Oxysis Forum 4-1 is available in a variety of sugars, from monosaccharides to polysaccharides, and also uses pectin or cellulose. Acetic acid and amino acid nitrogen promote the growth of non-pathogenic Fusarium oxis forum 4-1, and ammonia nitrogen is not used well.

탄소원에 대해서는 어느 정도량 이상에서는 생육은 좋은데 과다하거나 적은 경우는 균사밀도가 저하하며 포자형성량도 낮아진다.With respect to the carbon source, the growth is good at a certain amount or more, but in the case of excessive or small amount, the mycelial density decreases and the amount of spore formation decreases.

질소원에 대해서는 양의 증가와 함께 생육이 좋게 되는데 포자형성은 균량의 증가와 상관이 없으며 질소원 과다상황에서는 반대로 단위균체당 포자형성수가 감소한다.For nitrogen sources, the growth is good with the increase of the amount, but the sporulation is not correlated with the increase in the amount of spores.

한편, 오이덩굴쪼김병은 토양악화에 따라 발병이 조장되어 다발생 포장에서는 비병원성 푸사리움 옥시스포럼 4-1 균주처리효과가 낮고 소발생 포장에서는 높게 나타나는 경우가 있다. 그 이유는 다발생 포장은 병원균 밀도가 높거나 토양악화로 인해 발병억제 효과가 낮기 때문이다. 따라서 비병원성 푸사리움 옥시스포럼 4-1 균주의 비병원성균을 식물체에 미리접종하여 저항성을 증진하기 위해서는 재배지 토양의 환경을 고려한 비병원성 푸사리움 옥시스포럼 4-1 균주의 처리방법 개발이 필요하다. 한편, 비병원성 푸사리움 옥시스포럼 4-1 균주의 대량 배양 방법에 있어서, 오이의 경우는 균체를 뿌리에 침근 접종하는 것이 부적절하다. 그런데, 토양 밀기울 배양법을 검토한 결과, 원예용상토를 주재료로 하여 밀기울, 목탄분말과 같은 숯가루를 일정 비율로 혼합하여 배양토를 조제한 후, 수도용 육묘 상자에 배양한 경우, 비병원성 푸사리움 옥시스포럼 4-1 균주의 균체형성이 양호하는 것을 발견하였다. 나아가, 비병원성 푸사리움 옥시스포럼 4-1 균주가 대량 증식된 배양토를 폿트에 처리하고 오이를 육묘한 후 포장에서 재배한 경우, 농가관행 재배에서의 발병율이 45%인데 비해서 대량증식된 비병원성 푸사리움 옥시스포럼 4-1 균주의 배양토로 처리된 것의 발병율이 8%로 방제효과가 높았다. 따라서, 비병원성 푸사리움 옥시스포럼 4-1 균주의 전처리에 의한 오이덩굴쪼김병 방제효과는 기존에 보고된 길항균을 이용한 오이덩굴쪼김병 방제와는 전혀 다른 양상을 나타내는 것을 알 수 있다. 즉, 비병원성 푸사리움 옥시스포럼 4-1 균주는, 대량 배양되어 육묘 폿트에 전처리되고 포장에 이식되는 경우 토양에 존재하는 오이덩굴쪼김병균보다 밀도가 높게 유지되어 병원균의 침입이 억제된다고 추측된다. 또한, 육모 폿트에 비병원성 푸사리움 옥시스포럼 4-1과 유기질 자재를 혼합 처리하면, 식물체의 근권생장이 좋아지고 이것을 먹이로 이용하며 균량을 오래도록 유지할 수 있어서 오이덩굴쪼김병에 대한 억제효과가 나타나는 것으로 추측된다. 이렇게 비병원성 푸사리움 옥시스포럼 4-1 균주를 토양에 전처리함으로써 발병억제가 나타나는 것은 비병원성 균주와 유기질 자재를 혼합처리한 상토조제가 비병원성 균주의 밀도유지에 의한 병원균의 침입방지, 건전묘의 생장으로 발병이 억제되는 것으로 추측된다.On the other hand, cucumber vine crust disease is caused by deterioration of the soil, so the multipathy field may have a low treatment effect of the non-pathogenic Fusarium oxysporum 4-1 strain, and may appear high in a small field. The reason for this is that multivalent packaging has a low pathogenic effect due to high pathogen density or soil deterioration. Therefore, in order to improve resistance by pre-inoculating non-pathogenic bacteria of the non-pathogenic Fusarium oxysporum 4-1 strains to plants, it is necessary to develop a treatment method of the non-pathogenic Fusarium oxysporium 4-1 strains considering the environment of the cultivated soil. On the other hand, in the mass culture method of the non-pathogenic Fusarium oxis forum 4-1 strain, in the case of cucumber, it is inappropriate to inoculate the cells in the roots. However, as a result of examining the soil bran culture method, when the cultivation soil was prepared by mixing crushed charcoal powder such as bran and charcoal powder as a main ingredient in a predetermined ratio, and then cultivating it in a seedling box for water, the non-pathogenic Fusarium oxis forum It was found that the cell formation of the 4-1 strain was good. Furthermore, when the non-pathogenic Fusarium oxisforum 4-1 strain was treated with large-growth culture soil in pots, seedlings were grown, and then grown in the field, the incidence of farming practices was 45%, whereas the non-pathogenic Fusarium Fusarium was grown. The incidence of 8% strain treated with Oxygen Forum 4-1 cultured soil was high in control effect. Therefore, it can be seen that the control effect of cucumber vine cutting disease by pretreatment of the non-pathogenic Fusarium oxis forum 4-1 strain has a completely different aspect from the control of cucumber vine cutting disease using antagonists reported previously. In other words, the non-pathogenic Fusarium oxysporum 4-1 strain is presumed to be higher in density than the cucumber pruning pathogen present in the soil when it is cultivated in large quantities, pretreated in seedling pots, and transplanted into a package, thereby preventing invasion of pathogens. In addition, mixed treatment of non-pathogenic Fusarium oxis forum 4-1 with organic materials in the hair growth pot improves rooting growth of the plant, can be used as food, and maintains the amount of bacteria for a long time. I guess. The pre-treatment of non-pathogenic Fusarium oxis forum 4-1 strains in the soil shows that inhibition of pathogenesis is caused by the prevention of invasion of pathogens by the density maintenance of non-pathogenic strains and the growth of healthy seedlings. It is assumed that this is suppressed.

요컨대, 비병원성 푸사리움 옥시스포럼 4-1을 배양상토(부농상토:밀기울:숯가루)에서 대량배양하여 육묘상토와 혼합한 토양에 오이를 육묘하여 오이덩굴쪼김병이 많이 발생하는 농가포장에서 재배하면 이병의 방제효과가 대단히 우수하다. 한편, 배양상토와 육묘상토의 혼합비는 경제적으로 3:7이 바람직하다.In short, if a non-pathogenic Fusarium Oxy Forum 4-1 is grown in a cultured soil (floating soil: bran: charcoal powder), the cucumbers are grown in soil mixed with seedling soil, and then grown in a farmhouse package that generates many cucumber vine split diseases. The disease control effect is very good. On the other hand, the mixing ratio of cultured soil and seedling soil is economically preferably 3: 7.

이와 같이, 비병원성 푸사리움 옥시스포럼 4-1은 방제효과가 우수할 뿐만 아니라, 지속적으로 효과가 유지되고 타작물에 병을 일으키는 부작용도 없어 실용화시 오이덩굴쪼김병 방제용에 탁월한 효과를 가져올 가능성이 높다.As such, the non-pathogenic Fusarium oxis forum 4-1 is not only excellent in control effects, but also continuously effective and has no side effects that cause disease in other crops. high.

나아가, 본 발명에 있어서 오이덩굴쪼김병방제용 비병원성 푸사리움 옥시스포럼 4-1을 이용한 병해방제 효과 및 여러 가지 시험방법에 대해서는 하기의 실시예에 상세히 설명하고자 한다.Furthermore, in the present invention, the pest control effect and various test methods using the non-pathogenic Fusarium oxis forum 4-1 for cucumber vine split disease control will be described in detail in the following examples.

[실시예 1. 비병원성 푸사리움 옥시스포럼 4-1의 배양상토제 조제]Example 1 Preparation of Culture Topical Agent of Nonpathogenic Fusarium Oxysis Forum 4-1

비병원성 푸사리움 옥시스포럼 4-1을 배양하여 토양처리하는 방법으로는 액체배양에 의해 균을 대량으로 생산하여 이용하는 방법과 토양배지를 조제하여 여기에 비병원성균을 접종하여 증식 후에 사용하는 방법이 있다. 비병원성 푸사리움 옥시스포럼 4-1은, 하기 표 1에 나타난 바와 같이, 액체배양한 비병원성 푸사리움 옥시스포럼 4-1를 토양에 관주처리하는 것보다 토양배지에 배양하여 처리하는 것이 토양에서 높은 밀도로 유지되었으며 보다 안정적이다.There are two methods of cultivating the non-pathogenic Fusarium oxis forum 4-1 and treating the soil, and the method of producing and using a large amount of bacteria by liquid culture, and preparing a soil medium to inoculate non-pathogenic bacteria and use it after propagation. . As shown in Table 1, the non-pathogenic Fusarium oxis forum 4-1 has a higher concentration in the soil than in the culture of the liquid cultured non-pathogenic Fusarium oxys forum 4-1. It is kept at a density and is more stable.

또한, 토양배지를 조제하는 경우 배지의 조성이 가장 중요한데 본 연구에서공시한 배지조성중에서 표 2에서 나타난 바와 같이 시판용 부농상토에 밀기울과 활성탄을 조합하여 조제한 상토에 비병원성 푸사리움 옥시스포럼 4-1를 배양한 것이 가장 균 증식이 우수하였다.In addition, the composition of the medium is the most important in the preparation of soil medium.As shown in Table 2, the non-pathogenic Fusarium oxis forum 4-1 prepared from a combination of wheat bran and activated carbon in commercially available subcontracted soil as shown in Table 2 The best bacterial growth was achieved.

[실시예 2. 비병원성 푸사리움 옥시스포럼 4-1 처리방법]Example 2 Non-pathogenic Fusarium Oxysis Forum 4-1 Treatment Method

배양한 비병원성균을 미리 기주체에 접종하여 병 방제효과를 높이려고 하는 경우 접종방법에 따라 방제효과가 다르고 경제성도 고려하여야 한다. 따라서, 육묘상토에 비병원성 푸사리움 옥시스포럼 4-1를 처리하는 방법과 오이묘를 포장에 정식시 처리하는 방법을 비교검토하였다. 그 결과 부농상토와 배양균주를 혼합하여 육묘용 비닐폿트(직경 8㎝)에 담고 오이종자를 파종, 육묘하여 포장에 정식하는 방법이 병 방제효과도 우수하였으며 배양균의 처리량도 타방법에 비하여 훨씬 적게들어 경제성 면에서도 유리하였다. 그 결과는 표 3에 나타내었다.In order to increase the disease control effect by inoculating the cultured non-pathogenic bacteria into the host in advance, the control effect varies according to the inoculation method and economical consideration should be taken into account. Therefore, the method of treating non-pathogenic Fusarium oxis forum 4-1 on seedling soil was compared with the method of treating cucumber seedlings on the pavement. As a result, the method of mixing the subcontaminated soil and the culture strain in a plastic pot (8cm in diameter) for seedling, sowing and seeding the cucumber seeds and putting them on the package was excellent in controlling the disease, and the throughput of the culture was much higher than other methods. It was also advantageous in terms of economics. The results are shown in Table 3.
