잡초방제없이 합리적인 답작경영은 불가능하다. 잡초방제법에는 여러 가지 종류가 있으나 현재 일반적으로 많이 이용되고 있는 것은 생태적, 기계적, 및 화학적방제법이며 특히 근래에 제초제의 개발이용에 의하여 제초기술은 비약적으로 진보하고 있고 미국, 일본등 제국에서는 거의 전답면적에 제초제를 사용하고 있으나 우리나라에서는 상금 인력 및 기계제초를 위주로 하고 일부 제초제를 사용하고 있는 실정이다. 그러나 최근 급속한 경제성장으로 농업노동력이 격감되고 노임이 상승되므로서 농작업의 생력화가 절실히 필요하게 됨에 따라 제초제의 생략효과가 크게 인정되고 그 소비량은 1966년부터 급증하기 시작하여 1968년 현재 1961년의 49배나 되었고 그도입량은 1970년 현재 전농약수입액의 15%선까지 이르렀으며 앞으로 계속 증가될 필연적추세에 있다. 한편 우리나라에서의 답제초제에 관한 시험연구는 1955년부터 실시되여 현재까지 125건에 달하며 일부제초제의 효과를 구명하고 인력제초에 대신하는 답제초체계를 일응 제시하고 시험지간에 상호 유기적 연락이 결여되고 내용적으로도 간단한 응용시험에 끝였으므로 많은 시험수행에도 불구하고 제초제보급 및 사용상 여러 가지 문제를 야기시키고 있다. 따라서 상기한 여러 문제점을 시급히 해결하고 보다 효과적인 시험연구를 수행하여 농업생산성 향상에 이바지 하기 위하여 제초제에 관계하는 도입 연구 지도조직의 체계화와 아울러 연구원, 연구비의 강화증액 및 전담연구실의 설치가 절실히 요청된다.

This study was conducted to establish a nce insect pest control system, ~ es.ys tematic application of insecticides using carbohran and buproiezin, in Korea. The effects oi various dates of application and rates of buprofezin (25% WP) after carbofuran (3G) soil incorpombon in late May on the pop~~lation densities of the brown planthoppa (BPH) immigrating in July were investigated Appropriate application tune of buprofezin for the BPH that had evaded insecticidal effect of 5011 incorporated carbofuran was late July-early August. Application rate of buprofezln at 7.0g a.i/lOa was enough to suppress the BPH density. Buprofezin treatment after carbofumn soil incorporation could also suppress the whlte backed planthopper population but did not affect the densities oi the paddy rice spiders. Considering the charactenstics of occurring patterns of the nce insect pests in Korea. buprofezin treatment m late July or early August after carbofuran soil incorporation in late May can be a useful application system of ir~sectic~deins controlling early season Insect pests and migmtoly planthoppers on rice.

The three-year inspection of 20 tree stumps in the fire prevention area around the wooden building confirmed that termite colonies had been rapidly spread. In particular, four buildings among thirty one wooden buildings of Songgwang-sa temple were infected by the termite, indicating that the habitate of termite has been spread across the fire prevention area over the temple area. However, a non-destructive microwave diagnosis showed that internal damages have been progressed until now, suggesting a high risk to the building. These results suggest that the fire prevention area should be properly maintained to have harmful element controlled. Therefore, effective methods are required to eliminate tree stumps or wood materials used to establish fire prevention area near wooden buildings.

Tetranychus urticae Koch and Panonychus ulmi Koch were identified as quarantine pests in apple samples and were controlled soon after the commercial treatment of methyl bromide (MeBr) and with irradiation doses $(0.5{\sim}3kGy)$ after irradiation. The physical qualities of apples, such as rotting, withering, weight changes, hardness, and color, were apparently affected by MeBr. Furthermore, more than 2 kGy irradiation resulted from the lapse of storage time. Associated with the physical qualities of stored apples, irradiation and fumigation for quarantine purposes were more adequate after 40 days of storage at $0{\pm}1^{\circ}C\;(85{\pm}2%\;RH)$ immediately following harvest, rather than soon after harvest. Less than 1 kGy irradiation, based on its accumulated control effect on pests, can potentially be applied as a quarantine procedure without causing significant changes in the physical qualities of fresh apples, in contrast to MeBr.

건고추는 대부분 세척이나 살균의 과정을 거치지 않고 저장, 유통되므로 해충이나 미생물 오염에 의한 식품위생면이나 상품가치면에서 문제가 되고 있다. 고춧가루의 미생물과 해충 방제를 위하여 ethylene oxide나 propylene oxide 등의 훈증제가 사용되고 있으나 문제점이 많아 점차 사용이 금지되고 있는 실정에 있다. ${\gamma}$-선 조사는 훈증제, 자외선 조사, 초단파 처리등 기존의 방법에 비해 살균 효과는 물론 식품의 품질과 건전성 실험 결과에서도 우수하다고 보고되었다. (중략)

Antifungal bacterium, Bacillus subtilis YS1 was isolated from Yusong hot spring showed broad antifungal spectrum against 12 kinds of plant pathogenic fungi and Candida albicans, animal pathogen. From the gamma($Co^{60}$) radiation sensitivity test, $D_10$ value was 2.08 kGy and it survived above 20 kGy of radiation dose. Several mutants were induced by gamma radiation. Among them, YS1-1009 mutant showed resistance against tebuconazole of herbicide, increased activity against Botryoshaeria dothidea and ligninase activity. YS67 mutant was antifungal deficient auxotrophic mutants(trp-pro-or arg-ura-). From this results, it suggested that gamma irradiation could be useful method for mutant induction.

Objectives : The purpose of this study was to investigate the interpretation of the Gwibi-tang(歸脾湯, GBT) prescription in order to obtain the traditional significance. Methods : We have analyzed the interpretation on the GBT prescription through translations and comparisons based on classic books about the oriental medical prescriptions. Results : 1. The source of GBT in Dongeuibogam(東醫寶鑑) is Guchiryuyo(口齒類要), Jeongcheryuyo(正體類要) and Gyojubuinyangbang(校註婦人良方) etc. 2. Meaning of "GwiBi(歸脾)" in the GBT name is returning to the Bi(脾) which is origin of generating Gi(氣) and Blood(血). 3. GBT is composed of Sagunja-tang(四君子湯), Hwanggi-tang(黃芪湯) and Danggwibohyeol-tang(當歸補血湯) etc. 4. According to wide range of symptom, GBT can be varied by adding or subtracting herbs. Conclusions : In this study, we have demonstrated various methodologies. This paper will be useful to the future researchers and clinicians to conduct a study on herbal medicines such as the GBT.

Present status on the pesticides production, supply, manufacture and pests control in Korea are summarized. The data in the past several years (1971-76) are analyzed to find out the problems and solutions for the further development of plant protection and pesticide industry in Korea. Since the acreages of crop plantation and the quantities of pesticides uses are already near to the stage of plateau, pesticide formulation with imported technical grade should be modified by local synthesis with imported quality. The government pesticides management act and regulations must be modernized urgently in connection with the synthesis. formulation, tests, registration, quality control. price and supply system as well as the safety use of pesticides. Recommendation concerning acceptable daily intakes(ADI) and residue limits must be established for the strengthning pesticide safety use and plant protection activities as soon as possible. The use of fungicide-insectide mixture in dust formulation must be authorized and practiced immediately for the labor saving and one-hit cooperative mass control of rice disease and insect pests, especially. At present, serious considerations on pesticide safety use and integrated pest control are strongly urged to help the farmers, to save the industries and to keep the nature as it is required.

The prototypes, Rto-x+$Ca(NO_3)_2$, K-Ca, and Rto-$x{\beta}$, which were extracted from spent mushroom substrate of Hericium erinaceus, strongly inhibited the growth of Ralstonia solanacearum. The control efficacies of tomato bacterial wilt by treatment with Rto-x+$Ca(NO_3)_2$, K-Ca, and Rto-$x{\beta}$ were 87.4~92.4%, 46.0~100%, and 65.0~91.9%, respectively. These results indicate that Rto-x+$Ca(NO_3)_2$, K-Ca, and Rto-$x{\beta}$ have a potential as eco-friendly antibacterial materials for the control of tomato bacterial wilt caused by R. solanacearum.
