  • 비가림재배 포도원에서 발생하는 흰가루병에 대하여 triazole계 살균제 flusilazole, myclobutanil, difenoconazole, penconazole, triflumizole, triadimefon의 방제 효과를 검정한 결과는 다음과 같다. 살균제 처리구의 이병과방율과 이병엽율은 무처리구에 비해 현저히 감소하였고, 이들의 방제가는 과방에서 약제에 따라 94.7∼97.9%, 잎에서 85.5%∼90.9%였으며 대조약제인 polyoxin B의 방제가와 유사한 정도를 보였다. 공시살균제의 보호효과는 살균제를 병발생 1주일전에 살포하는 경우, 살포 3주 후에 방제가는 약제에 따라 72.2∼90.5%였으나 4주 후에는 21.2∼41.6%로 감소하여 대조약제 polyoxin B의 52.5%보다 감소시켰으나 myclobutanil의 발아억제 효과는 약제 농도증가에 크게 영향받지 않았다. 살균제에 침지한 cheesecloth를 포도원 선반에 매달아 조사한 공시살균제의 훈증효과는 살포농도의 2배로 처리했을 때 처리점으로부터 반경 30cm이내의 포도송이에서는 약제에 따라 57.2∼71.1%의 방제가를 보였으나 전체 식물체에서는 49.1∼65.8%로서 10일 간격으로 3회 살포한 것 보다 낮은 방제가를 보였다.

  • In most productive facility of pharmaceutical companies, the fumigation using formaldehyde gas has been put into operation. Because formaldehyde gas is so bactericidal as to sterilize bacterial spore which can not be sterilized with usual disinfectants, it has been used for fumigation in many facilities such as facility of experimental animals, research institute and productive facility of pharmaceutical companies which are required to be high level of biological clean. However, the use of formaldehyde is recently under the strict management because of its causing of sick house and carcinogenesis. We introduce the conditions of sterilization using formaldehyde gas, the examples of sterilization using formaldehyde gas in a pharmaceutical manufacture and the problems of use of formaldehyde against environments and health. Further, we describe the characteristics and future subjects of the sterilization method using gasified oxidants such as hydrogen peroxide, peracetic acid and chlorine oxide.

  • This study examines the effects and influences of fumigation on the antimicrobial treatment of excavated dresses in two different museum settings using chemical composite of Methyl Bromide and Ethylene Oxide. The microbial test indicated that the prewashed samples contained Micrococcus, Bacillus, Staphylococcus, and some unidentified fungi and that the total number of microbes decreased after washing. While it was observed that most germs were removed immediately after fumigation, Bacillus was still found and its number even increased. After 5 months, the number of microbes found in Museum A was smaller than Museum B, which shows that Museum A equipped with better environment control facility was superior to Museum. B in terms of exhibition and preservation of dresses against organic damages. In addition, the result indicates that fumigation is an effective measure against the growth and reproduction of microorganisms, considering that the number of microorganisms decreased after fumigation. The color of test sample showed immediate change after fumigation but color difference became stabilized and decreased with the passage of time. The test samples from both museums showed similar patterns.

  • Overwintering striped rice borer, Chilo suppressalis W. larvae, pupae and adults in rice straw handicrafts were exposed to different doses and periods of phostoxin in gas chambers(ave.temp. 27C). The following results were obtained; 1. For 100 percent mortality, larvae required 48 hours, pupae 24 hours and adults only 8 hours of exposure. 2. The insecticidal effect of tile fumigant was more dependent upon the length of exposure than the dosage of fumigant.

  • This study examines the effects and influences of fumigation using chemical composite of Methyl Bromide and Ethylene Oxide on the change of strength of excavated dresses. The fabric strength immediately after washing and fumigation increased slightly, but it decreased greatly as the time progressed. The strength of the test sample from Museum A showed a steady decrease with time, while that of Museum B decreased rapidly 5 months later. Compared with the non-fumigated sample, fumigated sample was greater in strength regardless of the time progression, and the strength of sample kept in the exhibit hall was greater than that kept in the storage room. The strength of the fumigated sample was almost same regardless of the three different time periods, before washing, after washing and immediately after fumigation, and it decreased steadily with time, whereas the non-fumigated sample became much weaker in its strength in 10 months after washing. Even 5 months later, the fumigated sample was about as strong as immediately after fumigation, but the strength dropped to a great extent 10 months later.

  • Effects of air-tighteness of packing material and aluminum phosphide fumigation on mortality of rice weevil were studied during rice storage. Air-tight storage of rice in sealed bag of 0.1mm PE film or sealed glass bottle reduced the deterioration of rice quality and killed all rice weevils after 60 days storage, while paper bag, PP bag and straw bag storage kept them alive. One tablet of aluminum phosphide in one cubic meter heap of rice packed in PP bag was sufficient to kill all rice weevil in it, when the heap was covered by 0.15 mm PE film during fumigation.
