This study was carried out to investigate the effects of pyroligneous acid on turfgrass growth and to propose usage for sustainable management on Korean golf course green. Each plot was treated with 0, 300, 500, and 800 acid to water solution. On all the plots, turfgrass growth increment and visual quality were measured at fried times. The data were subjected to paired samples t-test and corelation analysis. The summarized results are as follows; 1) Leaf growth increment, density, and root spread depth of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Particularly, 1: 500 diluted solution was superior to the others. 2) Color, texture, and uniformity of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Especially, 1: 500 diluted solution tended to be superior to the others. 3) There were no symptoms of disease in all plots treated with the diluted pyroligneous acid. 1 500 and 1: 800 diluted pyroligneous acid were not thought to trigger or promote disease. 4) Before and after investigating the effect of pyroligneous acid on turfgrass growth ,the soils were analyzed. In all treatments, the chemical properties of the soils did not change noticeably. The chemical properties of the soils might be not changed by the diluted pyroligneous acid treatments. 5) Considering the results mentioned above, 1: 500 diluted pyroligneous acid was the most effective. Though pyroligneous acid is an organic fertilizer and contains only a little nitrogen and phosphorus, 1: 500 diluted pyroligneous acid promoted turfgrass growth effectively. Thus this use might lead to a reduction in the amount of fertilizers used and result in ecologically responsive management of Korean golf courses.

목초액을 친환경 인삼재배에 이용하기 위하여 전엽기 이후인 6월 중순부터 지상부에 엽면시비로 살포하여 3년생 인삼 잎의 형태적특성과 수량에 미치는 영향을 조사하였다. 목초액을 처리하면 처리농도에 관계없이 해면조직의 배열이 3층에서 4층으로 증가하였다. 또한 인삼 잎의 상표피와 하표피의 두께가 두꺼워지고, 엽육세포도 두꺼워지는 효과를 보였으며 지하부의 생육에도 영향을 미쳐 무처리에 비해 뿌리의 생육이 증진되었으며 인삼 뿌리의 수량도 증가하였다. 따라서 목초액의 혼합사용은 인삼의 생육을 촉진시키고, 병해를 극복하여 인삼을 친환경재배 할 수 있는 대안이 될 것이다.

Alternatives to commercial chemical herbicide are currently being searched and tested due to the numerous adverse effects of commercially available herbicides to the environment. Barnyardgrass (Echinochloa crusgalli) is an important weed species around the world, especially in paddy rice fields. This study focuses on the favorable effects of mixing pyroligneous acids with commercial liquid herbicides. Seedlings were transplanted and grown under greenhouse conditions. The effect of treatment time or leaf-stage on herbicide-pyroligneous acid efficacies was checked, coupled with isolation and quantification of biochemical compounds. Results revealed that herbicide treatment at early post emergence (2~3 leaf stage) of Echnochloa crus-galli leads to effective control. Both liquid herbicides affected fatty acid, protein, and amino acid syntheses as reflected on their contents. The influence of wood vinegar (WV) or rice vinegar (RV) on these compounds was not thoroughly verified due to lack of information on the pyroligneous products. We observed that mixing WV or RV with BCB (bentazone + cyhalof-butyl) gives more favorable results than BUC (butachlor + clomazone), mixed with WV or RV. The result would indicate the potential of mixing pyroligneous acid in reducing herbicide application rate.

살균제와 목초액을 혼용하여 우리나라 골프장의 한국잔디에 가장 문제가 되는 라지패취 병에 대한 방제효과를 검정하였다. 목초액 500, 1000배액 단독처리 시 라지패취병이 발병하는 것으로 보아 목초액 단독 처리는 라지패취 발병을 억제시키지 않았다. 살균제와 목초액 혼용처리 시에 있어서 잔디의 라지패취 병은 목초액을 혼용함으로써 Pencycuron 과 tebuconazol에서 좋은 효과가 나타났으며, 라지패취병 방제에서 Pencycuron과 tebuconazol과 목초액을 혼용 하였을 때 농약을 $50\%$ 감량하는 효과가 있는 것으로 나타났다. 목초액 혼용 농도는 500배액이나 1000배 액에서 비슷하게 나타났다 엽폭, 엽장, 건물 중 모두에서 목초액 500, 1000배액 희석처리 구의 잔디가 목초액 무처리구에 비해 증가하는 효과가 있었다. 따라서 잔디에 발생하는 라지패취병 방제시 화학약제와 목초액을 혼용하여 살포하면 농약사용량을 $50\%$ 감량하여도 기준시용 처리구와 효과가 비슷하게 나타나 목초액의 이용가능성이 확인되었다.

pH in sausages with 0.5% and 2% pyroligneous liquor was lowered rapidly respectively. Sausage with 2% pyroligneous liquor showed the lowest Aw. Antioxidant activity of 0.02% and 0.5% pyroligneous liquor was negligible but rancidity was inhibited in the sausages with 2% pyroligneous liquor and 0.02% BHA/BHT(1:1) Sensory tests showed that sausages treated with pyrolignesous liquor had lower score. The growth of lactic acid bacteria was not affected by pyroligneous liquor. But enterobacteria was not detected after 10 days fermentation of the sausages wit 0.02% BHA/ BHT 8 days in the 0.5% pyroligneous liquor and 6 days in the 2% pyroligneous liquor.

목재의 탄화과정 산물인 목탄과 목초액의 농업적 이용의 일환으로 고추 생육 및 토양미생물에 미치는 영향을 조사하였다. 목탄과 목초액을 토양에 처리할 경우 토양을 중성으로 개량하는데 효과적이고 토양의 이화학적성질이 유용 미생물이 생육하기에 적합한 환경조건으로 변화되어 토양내 유용미생물의 밀도 증가로 나타났다. 고추의 생육에 있어서도 탄화물 처리로 고추모의 길이, 직경생장 및 고추 결과 수가 증가되었다. 특히 결과 수에서는 목탄 1kg, 목초액 1000배액 및 세균처리에 의하여 대조구보다 약 50% 정도의 증수 효과를 나타냈다. 고추모의 길이 및 줄기직경 증가는 노지에서 여러 가지 환경 변화 요인에 대한 저항성을 갖게 하여 최종 수확량의 증대로 나타날 것으로 사료된다. 고추 탄저병균에 대한 길항성 실험에서는 목초액 농도 2배, 10배에서는 곰팡이가 사멸되었고, 100배, 1000배 희석농도에서는 대조구보다 성장 속도가 둔화되었다.

본 연구는 국내 골프 코스에서 친환경적인 관리를 위해 ‘Penncross’Creeping Bentgrass (Agrostis palustris Huds.)의 생육에 대한 목초액의 효과를 구명하고 그 활용을 제안하고자 수행되었다. 그 결과는 다음과 같았다. 1) 엽 생장량, 생육밀도, 그리고 뿌리 생장깊이 에서 목초액 500배 희석과 800배 희석 처리된 잔디는 지속적으로 무처리된 잔디보다 우수하였다. 그리고 이것은 통계적으로 신뢰할 수 있었다. 특히, 목초액 500배 희석액은 다른 처리들보다 우수하였다. 2) 색상, 질감, 균일성, 그리고 회복력에서 목초액 500배 희석과 800배 희석 처리된 잔디의 시각적 질은 지속적으로 무처리된 잔디보다 우수하였다. 그리고 회복력을 제외하고 이것은 통계적으로 신뢰할 수 있었다. 특히, 목초액 500배 희석액은 다른 처리들보다 우수한 경향을 나타냈다. 3) 모든 실험구에서 병 발생은 없었다. 해당 골프 코스에서 기존의 관리방법이 적합하다고 판단되었다. 목초액 500배 희석과 800배 희석 처리가 병 발생을 유도하거나 촉진시킨다고 판단되지는 않았다. 4) 잔디 생육에 대한 목초액의 효과를 구명한 후에 모든 실험구에서 토양을 분석하였다. 모든 실험구에서 토양의 화학적 특성은 현저하게 변화되지 않았다. 5) 위에서 언급된 결과들을 고려할 때, 목초액 500배 희석과 800배 희석액은 골프 코스에서 잔디의 생육을 촉진할 뿐만 아니라 비료와 농약의 사용량을 감소시키는 것으로 예측되었다.

This experiment was conducted to clarify the effect of pyroligneous liquor on endogenous substances that were GA (gibberelic acid)-like substances, starch, and protein of Neofinetia falcata cultured in vitro. When seedlings of Neofinetia falcata were treated with several concentrations (0, 0.5, 1.0, 2.0, 3.0 ml/L) of pyroligneous liquor, the growth of seedlings was enhanced in 1.0ml/L pyroligneous liquor added media. The activity of GA-like substances was lower in the leaf, but higher in the and root than that of the control. The content of starch in 1.0ml/L pyroligneous liquor was lower in the leaf, but higher in the root than that of the control. And the content of protein in 1.0ml/L pyroligneous liquor was also lower in the leaf, but higher in the root than that of the control.

BACKGROUND: Coleosporium plectranthi, an obligate parasite, which is responsible for the rust disease of Perilla frutescens, a plant in Korea, commonly known as Perilla. All rusts are obligate parasites, meaning that they require a living host to complete their life cycle. They generally do not kill the host plant but can severely reduce growth and yield. Food and feed spoilage fungi cause great economic losses worldwide. It is estimated that between 5 and 10% of the world food production is wasted due to fungal deterioration. Rust disease of Perilla is highly frequent and is widely spread in Korea. The present study was designed to investigate a novel media for the urediniospore germination in vitro and anti-rust activity as well as GC-MS analysis of oak pyroligneous liquor. METHOD AND RESULTS: Urediniospores were collected from the infected leaf of Perilla. Spore suspension was made and the suspension was inoculated in the 2% water agar media with proper humidity, then they were incubated at $26^{\circ}C$ for 56 hrs. The GC-MS analysis of the oak pyroligneous liquor was also done to check the chemical composition. GC-MS analysis of the wood vinegar was found 15 compounds, among them o-mthoxyphenol (25.93%), 2,6-dimethoxyphenol (16.06%), 4-methylenecyclohexanone (10.69%), 2,3-dihydroxytoluene (7.84%), levoglucosane (6.14%) and propanoic acid (5.32%) were the major components. Different concentration of the oak pyroligneous liquor was used, and spore inhibition was recorded on the basis of spore counting. The best results were noted at the concentration of 50% solution where 31.8% spores were inhibited. CONCLUSION: On the basis of the chemical composition of the oak pyroligneous liquor and the activity recorded we can use it as an anti-rust agent.
