  • This study was performed to test the insecticidal and antimicrobial activity of plant extracts from clove, Sophora flavescens Aiton and neem. As the result of antimicrobial activity test, clove extract showed the strongest activity against Botrytis cinerea. In insecticidal activity test, the extract of Sophora flavescens Aiton was the highest against Nilaparvata lugens. The pyroligneous liquor (10%) and emulsified spreader (10%) were added to the extracts of clove and Sophora, respectively, to apply the environment-friendly rice field. In the field treated clove extract, disease damage occurred 49.1% and insect damage occurred 29.5% compared to control plot (100%). In the field treated Sophora extract, disease damage was 56.7% and insect damage was 21.0% compared to control plot (100%). In conclusion, plant extracts from Sophora and clove could control about 50% of disease and about 70% of insect damage that they could be used as environment-friendly resources to control disease and insect in rice farming.

  • Sophorae radix extract (SRE) has been registered as an environment-friendly organic material that is widely used in the cultivation of crops in Korea. Matrine, the active ingredient in SRE, was reported as a toxic substance in the nervous system in mice. However, no information is available on its toxic effects in other organisms. Therefore, antimutagenicity and two kinds of genotoxicity tests (bacterial reverse mutation and chromosome aberration test) of two samples of SRE were investigated in this study. Antimutagenicity test was experimented by using bacterial reverse mutation test. In the reverse mutation test, Salmonella Typhimurim TA98, TA1535 and TA1537 were used to evaluate the mutagenic potential of SRE. Bacterial reverse mutation test was also performed on positive and negative control groups in the presence of the metabolic activation system (with S-9 mix) and metabolic non-activation system (without S-9 mix). In the chromosome aberration test, Chinese hamster lung cells were exposed to SRE for 6 or 24 hours without S-9 mix, or for 6 hours with S-9 mix. Negative and positive control groups were experimented for chromosome aberration test. As a result, the number of mutated colonies induced by 4-NQO were reduced by SRE treatment in all strains, indicating that SRE may have antimutagenic effects. Reverse mutation was not shown at all concentrations of SRE, regardless of application of the metabolic activation system. In the chromosomal aberration test, one of the SRE sample gave a suspicious positive result at 250 ${\mu}g/ml$ in the presence of S-9 mix. For the more adequate evaluation of the genotoxic potential of SRE samples, other in vivo genotoxicity study is needed.

  • Greenhouse whitefly, $Trialeurodes$ $Vaporariorum$, is the most important insect pest in environmental friendly tomato production. Natural enemies, $Nesidiocoris$ $tenuis$ and environmental friendly agricultural materials (EFAM) are major control agents in Korea. The aim of the present work is to evaluate release time of $N.$ $tenuis$ in controlling of $T.$ $vaporariorum$ and to select environmental friendly agricultural materials (EFAM) to suppress both $T.$ $vaporariorum$ and $N.$ $tenuis$ which if the density were high causing necrotic rings. Six EFAM selected to control of $Trialeurodes$ $Vaporariorum$ in three times spray with seven days intervals. Three EFAM showed high mortality 67.7-70.5% in spray after release plot but low in release after spray plot. It should be careful to spray with $N.$ $tenuis$. When $N.$ $tenuis$ were early release at 7 days after transplanting which before occurring and establishment of greenhouse whitefly, it could suppress the density. Extracts of bead tree + matrin, matrin 1, Chrysanthemum showed high mortality on $T.$ $vaporariorum$ adults and $N.$ $tenuis$. The results suggested that this three EFAM could be control agents of the damage of necrotic rings from $N.$ $tenuis$.

  • The effects of lightyellow sophora, Sophora flavescens extract were tested on non-specific immune response and a disease resistance of olive flounder, Paralichthys olivaceus. For feeding trial, weight gain of fish fed different treated groups were not significant differences. Serum analysis of treated and control group did not demonstrated any differences. Lysozyme activity in the kidney and spleen of the 0.05% treated group on $4^{th}$ and $8^{th}$ week showed significant increase, respectively. In addition, phagocytic activity of the 0.05% treated group on $4^{th}$ and 8th week showed significant increase compared to the control group. Histopathology of the liver and kidney tissue of the administrated group for $4^{th}$, $8^{th}$ and $12^{th}$ week showed no particular signs of tissue degeneration. The treated group was higher than control group by analyzing the relative percent survival (RPS) of the experimental challenge of Edwardsiella tarda. Therefore, the lightyellow sophora showed effective in preventing fish-pathogenic edwardsiellosis for a certain period of time.

  • Promoting the organic farming, much of the plant extracts used for controlling pests and fungi have been imported from China, India and Myanmar. But, it is so worrisome that aquatic animals such as muddy loach inhabiting in paddy field and common carps in river exposed to the pests and fungi likely be harmed. This study was conducted in order to evaluate the risks of aquatic animals influenced by the three plant extracts, i.e. Sophora flavescens, Azadirachta indica and Derris elliptica. The toxicities of common carp (Cyprinus Carpio), muddy loach (Misgurnus anguillicaudatus) and PEC (Predicted environmental concentration) exposed to the three plant extracts were estimated by the typical spray volume method. Risks were determined by the toxicity value as 48-hr $LC_{50}$ (Lethal concentration, median) or NOEC (No observed effect concentration) into PEC. 48-hr $LC_{50}$ of Common carp and NOEC by Sophora flavescens extracts was 7.9 and 6.2 mg/L, 26.8 and 21.8 mg/L by Azadirachta indica extracts and 47.0 and < 24.0 mg/L by Derris elliptica extracts, respectively. 48-hr $LC_{50}$ of Muddy loach and NOEC by Sophora flavescens extracts was 16.9 and 10.0 mg/L, 35.6 and 30.0 mg/L by Azadirachta indica extracts, and 73.9 and < 40 mg/L by Derris elliptica extracts, respectively. Therefore, acute toxicities of the three plant extracts for aquatic animals were proved to be very low level. PEC of Sophora flavescens extracts in paddy, drainage and river water was 68.0~3.0, 11.33~0.50 and 3.0~0.0018 mg/L, respectively. TER of Sophora flavescens extracts in the three water was 0.2~5.6, 1.5~33.8 and 2.6~4388.9, respectively. PEC of Azadirachta indica extracts in paddy, drainage and river water was 90.9~1.2, 15.2~0.2 and 4.8~0.00075 mg/L, respectively. TER of Azadirachta indica extracts in the three water was 0.4~29.7, 2.3~178.0 and 4.5~35733.3, respectively. PEC of Derris elliptica extracts in river water was 0.0063 mg/L. TER of Derris elliptica extracts in river water was 5222~15667.

  • This study was conducted to identify the insecticidal effect of a mixture of sophora extract and Bacillus thuringiensis against Spodoptera exigua on potted chinese cabbage in both laboratory and plastic house condition. In laboratory condition, mortality of larvae by BT ($1{\times}10^5$, $1{\times}10^6$, $1{\times}10^7cfu\;ml^{-1}$) alone was 27.5%, 51.3% and 92.5%, respectively, which was depend upon concentration of BT. Control efficacy of the mixture of BT and sophora extract was 98.8%, 88.8% and 91.3% which was higher than BT treatment only. The mixture of sophora and lower BT concentration was showed more increase of control efficacy. Anti-feedant effect by BT was depend on concentration of BT. At field experiment, the mixture of BT and sophora extract appeared higher mortality (72.2%, 67.8%, 61.1%) than BT treatment only (14.4%, 26.7%, 66.7%) similar with laboratory experiment. The mixture was less affected by environmental condition at field than BT only. Therefore, for effective control of beet armyworm without possibility to develop resistance against BT at farm, treatment of the mixture of sophora extract (0.033%) and BT ($1{\times}10^5cfu\;ml^{-1}$) would be considered more effective than BT treatment only.

  • BACKGROUND: Azadirachta Indica extract(AIE) and Sophorae radix extract(SRE) are widely used as environment-friendly organic materials of plant origin in South Korea. METHODS AND RESULTS: In this study, the in vitro micronucleus(vitMN) tests of two samples of AIE and SRE were conducted to evaluate their genotoxicity using the Chinese hamster lung(CHL) cell. This study was composed of two parts; cytochalasin B(cyto B) test and non-cyto B test. Mitomycin C and colchicine were used as positive controls. As a result, the incidence of micronucleus(MN) in all AIE and SRE treated groups increased in dose-dependent manner, but were less than 2.2% in 1,000 binucleated cells. In addition, there were no significant increases of MN incidence in all AIE and SRE treated groups, compared with the negative control group. CONCLUSION: Therefore, we suggest that AIE samples and SRE samples used in this study may have no genotoxicity in the in vitro micronucleus test using the CHL cells. In our previous study, we reported that AIE and SRE did not cause genotoxicity in Ames test. According to the genotoxicity battery system, we concluded that AIE and SRE used in this study have no genotoxic effects to humans.
