강원도 아스파라거스 파총채벌레 방제를 위한 종합적 방제방안
전신재 ( Jeon,S. J. ),김삼규 ( S. K. Kim ) 강원대학교 농업생명과학연구원(구 농업과학연구소) 2019 강원 농업생명환경연구 Vol.31 No.2
아스파라거스를 가해하는 총채벌레류 해충을 방제하기 위한 방법 중 가장 효과적은 방법은 살충제를 처리하는 것이나 아스파라거스의 경우 매일 수확하기 때문에 수확기에는 살충제 처리가 용이하지 않다. 아스파라거스에 발생하는 해충을 방제하기 위해 적용가능한 살충제는 총 114종이 등록되어 있으며 그 중 총채벌레 방제용 살충제는 60종이 등록되어 있다. 봄 수확기에 살충제를 처리할 경우에는 등록된 약제 살포 3-5일 경과 후 잔류허용기준 또는 정량한계 미만으로 검출되므로 잔류특성이 검증된 약제 살포 후 수확 한 아스파라거스를 저온저장고에 3일 이상 저장 후 출고하면 아스파라거스 농약잔류 안전성에 문제가 되지 않는다. 끈끈이트랩을 이용한 총채벌레 방제시 노란색과 파란색 끈끈이트랩 중 노란색 끈끈이 트랩의 파총채벌레 유인효과가 뛰어났다. 이산화탄소를 이용한 총채벌레 방제의 경우 60% 농도, 20°C, 24시간 또는 40%, 24°C, 24시간 처리 조건일 때 파총채벌레 성충과 유충에 대한 높은 살충효과를 나타냈다. 아스파라거스를 저장하는 2-4°C의 경우에는 고농도의 이산화탄소를 72시간 처리에도 유충이 살아남아 방제효과가 높지 않았다. 곤충병원성 곰팡이인 Beauveria bassiana와 Lecanicillium attenuatum은 토양에서 자연적으로 발생하는 곰팡이로 약제 살포가 어려운 봄 수확기 이전 토양에 존재하는 총채벌레 번데기를 방제하여 초기 총채벌레 밀도를 감소시키는데 큰 도움을 준다. Thrips are among the most important pests of asparagus. The most effective method to control this pest is to insecticides spraying. Currently, a total of 114 pesticides have been registered for the control of pests of asparagus, 60 of which are registered for thrips control. However, crops are harvested every day, applying insecticides to control thrips is not ideal. Moreover, a recent study has shown that depending on the type of registered insecticide used, less than the residual or quantitative limit could be detected at 3-5 days after spraying. Therefore, if the asparagus is harvested after the application of insecticides, it should be stored in a cold chamber for 3 or more days before being moved to market. The use of sticky traps to control thrips is effective not only for monitoring them but also for reducing their numbers without applying insecticides. Yellow and blue sticky traps were usually used, but the yellow traps have been shown to attract more thrips than the blue ones. A recent study showed the high insecticidal effects of carbon dioxide on adult and larval thrips, at 60% concentration (20°C for 24 hours) or 40% concentration (24°C for 24 hours). Soap was also shown to have a high insecticidal effect after thrips-infested asparagus was immersed in soap water (diluted 1,000 times) for 15 minutes. Entomopathogenic fungi, such as Beauveria bassiana and Lecanicillum attenuatum, which occur naturally in soil, also help to reduce the initial thrips population by attacking the pupae in the soil in the spring harvest period.

There are two sides of love between men and women: one is noble love that makes you to rise above the secular world and ascend to ideal realm, and the other is graceful love that makes you to give birth to a child and live a fruitful life in real world. The love, which Yu-jeong Kim had on his mind was the latter. It is more primitive and practical than the former. There are two types of love that brings salvation to human beings: One is religious love and the other is maternal love. What they have in common is that they are both unconditional. But, the religious love, which is based on afterlife, aspires towards ideal world, while maternal love is about this life. Among the two, the latter was more important to Yu-jeong Kim. He perceived maternal love to be greater than religious love. It is more primitive and practical than religious love. According to his ideas, there are two types of terrestrial love: Jeong情, and the ‘great love’, which he suggested. Yu-jeong Kim suffered depression and was a strict believer of misanthropism, but at the same time he desired to be a part of crowds and live a humane life. A humane life is a life full of jeong情. Jeong情 is what puts together Korean society- a human friendly culture. In this troubled chaos that is current days, the last hope that remains to us human beings is the ‘great love’. The concepts of the ‘great love’ are: First, it is the love towards community, not individuals. Second, the love towards community is more primitive than the love towards individuals. The love towards a community comes before the love towards an individual at this time of individualism. Third, it is the love towards needy grass-roots. Fourth, it is the love on the level of empathy, and not of sympathy and charity. In the end, the ‘great love’ is an expansion of jeong情. Yu-jeong Kim literature should not be appraised as literature full of reminiscence or recollection of old days just because the ‘great love’ is primitive. It is not a regression to the past, but a new discovery. The place where he discovered the ‘great love’ is his hometown of Shillae(currently Kangwondo Chuncheonsi Shindongmyun Jeungli). Peasants in this village had lived in a community that suggested ‘great love’ in their daily lives. He planned to embody this ‘great love’ he discovered in his hometown into his work, but could not. He spent a winter with sleepless nights putting up notes on his wall and getting lost in his thoughts, planning to start working on a new novel late in the next summer. But he passed away on March 29th before the summer came.
