We studies a model for management of pepper anthracnose based covering method and spraying system in field. 1. Among 82 organic fungicides, 42 materials showed most effective inhibition against mycelia growth of the Colletotrichum acutatum in vitro. 23 formulated biocontrol agents were chosen to control the disease from 42 biocontrol agents in greenhouse. In the end, five kinds (2 plant extracts, 2 biopesiticides, 1 Bordeaux mixture) were selected from 23 materials in the field. 2. The mulching materials of bed covering in fruit season were thin non-woven fabric sheet and black plastic. The use of a fabric sheet was reduced the spread of anthracnose as compared to the plastic covering. 3. The application with the chosen materials was reduced 34% of anthracnose for 7 times sprays to planting 70 days as compared to the untreated control. In yield, nonwoven fabric sheet with formulated biopesticides was increased 17% than black plastic. 4. This result indicated that the developed biocontrol strategy could be an effective and economic crop protection system in organic pepper cultivation field.

This study was carried out to development the environment-friendly control method of Myzus persicae using Beauveria bassiana and Environment-friendly agricultural materials (EFAM). Germination rate the dried conidia of B. bassiana was 90 percent at $24{\sim}27^{\circ}C$ temperature condition. Mortality of M. persicae was 56.7% at $1{\times}10^7$ cfu/ml conidia concentration. Four EFAM such as Pachungtan, Wangjungwang, Newbiodakill, Muginchon were low toxicity to B. bassiana growth. Among them, Muginchon (derris extract) and Wangjungwang (neem extract) could have synergistic effect to aphid mortality when mixing treat with B. bassiana, which protection value was 99% in 3 days after treat.

This study is to assess the level or consumer's attitude or food safety and their effects on the purchase or environment friendly agricultural products. For these purposes, the survey was implemented to 550 adults who resided in Seoul and metropolitan area. As a results, a lot of respondents perceived the five food hazards, pesticides, food additives, BSE, chemical materials, GMOs as the severest food risks. Results revealed that women, the most educated, married, and the older respondents were more likely to be negative about food safely. And Also, consumer's knowledge of environment friendly agricultural products was lower than the median. The respondents who have bought environment friendly agricultural products were 80.5% of the entire respondents. Also, the educated and the consumers who had the knowledge of the environment friendly agricultural products started to purchase them. The consumers who had higher income, perceived the food hazards(BSE), assessed agricultural products safety negatively, had willingness to pay them and more knowledge of environment friendly agricultural products were likely to purchase them usually.

The objective of this study is to analyze the performance and farmer's awareness on the large-scale environment-friendly agricultural districts (LEAD). For this, we survey 393 farmers who cultivate in the 14 LEAD. Most of farmers aware a necessity of LEAD project. They have a higher awareness and practical use on the 'production facilities and equipments for environment-friendly agricultural materials' and 'resource recovery center of crop-animal farming'. The spread and consciousness on the environment-friendly agriculture increase before LEAD project. Also the environment-friendly agricultural areas and incomes slightly increase. The results of this study show that the LEAD project need a modification in to response to change of agricultural issues and customer's needs.

Anthracnose caused by Colletotrichum gloeosporioides, which is one of the major diseases of red dates, causes severe damages in jujube (Zizyphus jujuba Miller) production in Korea. This study was done to evaluate the inhibition of anthracnose occurrence and pathogen growth by the treatment of environment-friendly materials such as a Bordeaux mixture and loess-sulfur mixture and by defense-response signaling in jujube. The in vitro test of the environment-friendly materials and signaling molecules that were routinely applied did not exhibit any antifungal activities against the pathogen for jujube anthracnose. The Bordeaux mixture and loess-sulfur mixture at a two-fold concentration showed inhibition zones that were 16.0 and 20.3 mm in diameter, respectively. In the pathogen inoculation test with detached jujube tree leaves, while treatment with the environment-friendly materials diluted by half showed no inhibition of lesion development, they did show inhibition of lesion development when they were routinely applied to the leaves. In detached jujube fruits inoculated with the pathogen, better suppressive effects by the treatment of the environment-friendly materials were seen in the fruits at a young stage rather than in the ripening stage. The in vivo test with jujube trees in pots showed that the treatment of salicylic acid (1 mM) resulted in the best suppressive effects against lesion development. The results suggest that it is possible to manage the incidence of anthracnose by the treatment of environment-friendly materials such as the Bordeaux and loess-sulfur mixtures and signaling chemicals such as ethephon, hydrogen peroxide, methyl jasmonate, and salicylic acid in jujube trees and fruits. Consequently, these findings suggest that environment-friendly materials and defense response signaling molecules could be used as suitable candidates for sustainable agrochemicals to manage anthracnose in jujube production.

The principle goal of environmentally-friendly agriculture is to maintain and conserve water and agriculture environment including drinking water resources by properly using agricultural materials such as agricultural chemicals, chemical fertilizers, and other agricultural materials according to act 19 of foster law of environmentally-friendly agriculture. To achieve these goals, we have to establish Integrated Nutrient Management(INM) and Integrated Pesticide Management(IPM) which are most important core technologies for environmentally-friendly rice cultivation. However, there are lack of criteria and technology for evaluation category according to soil management and its soil classes to practice an environmentally-friendly agriculture. Therefore, we should eatablish the standards to produce the safe agricultural products based on the soil physical and chemical characteristics which are basic properties of soil to accomplish the principle aims of environmentally-friendly agriculture.

The Purpose of this paper is to analysis on farmer's awareness and satisfaction level of the project for developing large-scale environment-friendly agricultural districts (LSEAD). To analysis farmer's awareness and satisfaction level, a series of farm household surveys were conducted on farmers, take part in the project for developing LSEAD. The sample size of the survey is 80 respectively. As a survey result, awareness and practical use of facilities & equipment shows a little different outcome. Satisfaction level of the project for developing LSEAD is summarized as follows. Influence on disposal of livestock excretions and farmer's consciousness change appears 4.47 and spreading environment-friendly agriculture 4.44, distribution of environment-friendly agricultural product 4.33, and demand of environment-friendly agricultural materials 4.04. In order to sustainable development of LSEAD, a governance system should be established.

시설재배지 내에서의 친환경농자재는 해충방제, 식물병방제 등의 작물보호를 위해 사용하기도 하지만, 작물의 생육을 도와주는 역할을 위해 사용되기도 한다. 이러한 친환경농자재는 점박이응애를 방제하기 위하여 사용되는 천적인 칠레이리응애와 중복 사용될 수 도 있다. 이때 친환경농자재가 칠레이리응애에 미칠 수 있는 영향을 평가하였다. 본 실험에 사용된 친환경농자재는 함유된 물질과 사용방법에 따라서 61개를 선발하여 사용하였다. 친환경농자재를 직접 칠레이리응애에 분무하였을 경우, 심각한 독성(10% 이하의 생존율)을 보이는 친환경농자재들은 IEFAM C와 FEFAM A, EFAMSM A, D, EFAMPE A, EFAMCh B, EFAMME A, EFAMMo C 등이었으며, 영향이 거의 없는 농자재들로는 FEFAM C, D, EFAMSM C, EFAML A, EFAMME C, E, H, J, EFAMMo G, I등이었다. 친환경 농자재를 살포한 후에 남아있게 될 잔효독성을 평가한 경우, 48시간이 경과한 후에 EFAMSM I, EFAMME A, EFAMMo A, C, I 등이 독성이 매우 높은 것으로 평가되었다. 그러나 EFAMCh C와 EFAMMo B는 칠레이리응애에 안전한 것으로 평가되었다. 따라서 친환경농자재를 사용하고자 할 경우에는 칠레이리응애에 대한 독성을 평가하는 것이 필요할 것으로 생각된다.

무당벌레(H. axyridis)는 세계적으로 진딧물의 포식자로 널리 알려지면서 농생태계내에서 진딧물을 방제하기 위한 방제인자로 많이 사용하고 있다. 또한 국내에서는 농약의 사용을 억제하는 정부정책과 소비자의 요구 등으로 인하여 친환경농업이 확대되면서 친환경농자재들이 많이 사용되고 있다. 따라서 친환경농자재의 사용은 무당벌레에 직간접적으로 영향을 미칠 수가 있다. 살충성친환경농자재(IEFAMs)의 경우 무당벌레의 각 발육단계에 대하여 대부분 안전한 경향을 나타내고 있다. 살균성친환경농자재(FEFAM)의 경우에도 FEFAM A를 제외한 다른 종류들은 무당벌레에 대하여 영향이 적다. 토양미생물친환경농자재(EFAMSM)인 EFAMSM C와 H는 무당벌레 알의 부화율을 떨어뜨릴 수가 있으며, EFAMSM A와 F는 1령 유충에 피해를 줄 수 있는 것으로 조사되었다. 식물성추출물친환경농자재(EFAMPE)는 EFAMPE A와 D는 무당벌레 알에 치명적인 독성을 보이고 있는 것을 알 수 있다. 그 이외의 다른 조사된 농자재들은 무당벌레에 비교적 독성이 약한 것으로 평가되었다.
