Highly bio-active plant essential extracts and oils from pepper, clove bud, rosemary and origanum which are selected to develop environment-friendly insecticides was studied for their acute toxicity. The results of acute oral toxicity using rats showed
value of over 2,000 mg/kg bw for pepper, clove bud, rosemary and origanum oils. The calculated acute dermal
value of pepper was over 4,000 mg/kg bw and anther testing materials was over 4,000 mg/kg bw. The skin irritation test showed that pepper, clove bud and rosemary oils had no irritation while origanum oil had a moderate irritation. According to the eye irritation test, it showed that there was no irritation for pepper and rosemary oils, while there were irritation for clove bud and origanum oils. Consequently, pepper and rosemary oils were shown to be low in toxicity whereas clove bud oil was indicated to cause a mild eye irritability and origanum oil, causing a moderate skin and eye irritability.

This study was carried out to examine residual pesticides in dried agricultural products collected from Gyeonggi province in 2010. A total of 102 samples was collected and analyzed for 206 pesticides by multiresidue method using GC-
, GC-NPD, GC/TOF/MSD, HPLC-UVD, HPLC-FLD and HPLC/MS/MS. The detection rate of residual pesticides was 23.5% (24 of 102 samples) and the agricultural products exceeding their MRLs (Maximum Residue Limits) were 1 sample of pepper leaves. Additionally, the frequently detected pesticide were chlorothalonil, fenvalerate, chlorpyrifos, endosulfan, bifenthrin, cypermethrin, hexaconazole and iprodione. The pesticide types detected in the dried agricultural products showed in the descending order of organophosphorus (22%), pyrethroid (22%), organochloride (17%), dicarboxymide (11%), carboxymide (6%), carbamate (6%), triazole (5%) and the others (11%).

This experiment was carried out to examine the residual amount variation of carbendazim and chlorpyrifos in fruit parts of red pepper according to the open field and/or the rain shelter house. It was shown higher residual amounts of agrochemicals in the field than the house condition at two hours (0 day) after chemical application, but it was shown higher residual amounts in the house at 5 days and 10 days. Although the residual amount in the field was higher than in the house at the beginning, the chemicals fast degraded in field condition. Carbendazim and chlorpyrifos remained as time passed in order of receptacle, but the residual amounts of two chemicals in leaf at
day. Carbendazim and chlorpyrifos were lessened until 10 days after chemical application, and reduction rate were 19.1% and 66.4% in flesh, 45.2% and 62.3% in receptacle, and 41.6% and 72.0% in the stalk, respectively. The reduction rate at 15 days showed 31.1%, 75.3% in flesh, 43.5%, 81.7% in receptacle, and 47.7%, 82.8% in stalk, respectively. Therefore the reduction rate of carbendazim showed receptacle > stalk > flesh, and that of chlorpyrifos showed stalk > receptacle > flesh in order. The calculated half-life of carbendazim showed 29.6 days in flesh, 13.6 days in receptacle, and 16.0 days in stalk, but that of chlorpyrifos showed 8.3 days in flesh, 8.3 days in receptacle, and 6.3 days in stalk. In conclusion, the half-life of carbendazim was longer than that of chlorpyrifos in even part, and especially was longest in flesh part of fruit.

Fenoxycarb, pyriproxyfen and methoprene are juvenile hormone mimic insecticide. These insecticides have been widely used for mosquito, fly, scale insects, and Lepidoptera. The purpose of this study was to develop a simultaneous determination procedure of fenoxycarb, pyriproxyfen and methoprene residues in crops using HPLC-UVD/MS. These insecticide residues were extracted with acetone from representative samples of four raw products which comprised brown rice, apple, green pepper, and Chinese cabbage. The extract was diluted with saline water, and then n-hexane/dichloromethane partition was followed to recover these insecticides from the aqueous phase. Florisil column chromatography was additionally employed for final clean up of the extract. The analytes were quantitated by HPLC-UVD/MS, using a
column. The crops were fortified with each insecticide at 3 levels per crop. Mean recovery ratios were ranged from 80.0 to 104.3% in four representative agricultural commodities. The coefficients of variation were less than 4.8%. Quantitative limit of fenoxycarb, pyriproxyfen, and methoprene was 0.04 mg/kg in crop samples. A HPLC-UVD/MS with selected-ion monitoring was also provided to confirm the suspected residues. The proposed simultaneous analysis method was reproducible and sensitive enough to determine the residues of fenoxycarb, pyriproxyfen and methoprene in the agricultural commodities.

Recent outbreak of new diseases and pests which were introduced from abroad, seriously hampered both quality and safety of paprika fruits. This study has been carried out to aid an establishment of guideline for safe use of pesticides and reduction of their residues on paprika. Systemic fungicides boscalid and pyraclostrobin of either mixed (a.i.; 13.6+6.8%) or single (a.i.; 47 and 18.8%, respectively) water dispersible granule formulation(WG) products were sprayed with recommended or double dosage on paprika grown in green house at March and June. To draw pre-harvest residue limit, residues of each fungicide were analyzed from fruits collected eight times from 18 to 1 day pre-harvest. The biological half-lives of both boscalid and pyraclostrobin in mixed formulation in March and June were slightly shorter than those of single formulation which ranged from 14.4 to 20.1 days. Residue levels of both fungicides of single formulation in fruits in June were about one lower compared to those in March. However, application of double dosage frequently exceeded MRLs from fruits grown both seasons. These results showed that residue levels on fruits persisted longer period of time, more than two weeks, and so the case applied in winter season. The dissipation of fungicides on leaves and fruits was compared. The distribution of both fungicides in leaves was 20-200 times higher than that of fruits and persisted up to 18 days of pre-harvest period at the concentration of 10-40
. This study indicated that the mixed formulation product exhibited low residues in fruits, but high and long enough to pathogen growth in leaves.

This study was conducted to evaluate the safety of
-carotene biofortified rice, a genetically modified organism (GMO) developed by Rural Development Administration.
-carotene biofortified rice were exposed on Sprague-Dawley rats for 13 weeks. All rats survived until the end of the exposure period. There were no biologically significant differences in body weight, feed and water consumption, weight gains and feed efficiency. There were no clinical signs of toxicity attributable to exposure to GM rice. Mild decreases in AST, ALT, TG levels were observed in Group II (25% GM rice (w/w) and Group III (50% GM rice (w/w), both in females and males. Results of histopathological changes treated with the
-carotene biofortified rice had no significant differences between the control and treatment groups. Based on these results, we deemed that genetically modified
-carotene biofortified rice was as safe as conventional rice.

As part of safety evaluation of 2A (amono acid), PAT (phosphinotricin Acetyl-transferase), CtrI (Carotene desaturase) and PSY (phytoene synthase), the expressed proteins inserted to
-carotene Biofortified rice were tested for antigencity test. As a result, the group of administering high-concentration PAT, the expressed protein, showed a great content of total WBC; however, other expressed proteins did not show much difference. Against ASA (Active Systemic Anaphylaxis) test, the group of administering high-concentration PAT, the expressed protein, showed mild or medium degree of symptoms, but there was no dead entity. According to the result of the PCA (Passive Cutaneous Anaphylaxis test), the group of administering high-concentration PAT, 2A, PSY, and mixture of expressed proteins indicated positive response in low anti-serum concentration, and the group of administering the clinical concentration of mixture indicated mild positive response. However, because the group of administering the clinical concentration of expressed proteins, PAT, 2A, PSY, and CtrI, did not show positive response, it is thought that IgE is not generated. Further studies are needed to verify the safety of
-carotene Biofortified rice.

Bacterial wilt, caused by Ralstonia, solanacearum, is a very destructive disease to tomato plants (Solanum lycopersicum) in Korea. This study was undertaken to find out the growth inhibitory effect bactericides on bacterial wilt pathogen of streptomycin, oxytetracyclin streptomycin sulfate WP and significantly suppressed the growth of bacterial wilt pathogen. Copper hydroxide WP showed control value of 62.5%. Therefore, it is concluded that the bactericide used in this study showed strong inhibitory effect to tomato bacterial wilt and they can be recommend to control the disease. And also, Copper hydroxide WP may be effective for control of bacterial wilt of tomato in conventional culture, farming without agricultural and organic farming.

This study was carried out to investigate the evaluation of insecticidal efficacy and control effect in field of 10 environmental-friendly agricultural materials (EFAM) and seasonal occurrence at the vineyards to the Lycorma delicatula. L. delicatula nymphs occurred from late May to late August the highest early June (1st nymph) while adults occurred from late July to November with the highest peak of early October (preovipositing female) in 2010. Total population density of L. delicatula was the highest in early June. For the 3rd~4th nymphal instars and adults, EFAM (Spider, Jindikap-plus and Byejin-
) showed perfect insecticidal activity 2hour after treatment. Seoncho showed insecticidal activities 96.7% within 48 hour. Residual effects between EFAM showed 55.5% Spider at recommended concentration at 7 days after treatment(DAT), the other EFAM had low efficacy. Jindikap-plus and Spider showed 99% control value on nymphs in the field test at 3DAT, appeared control value more than 90% at 7DAT. Also, the control effects of Jindikap-plus and Spider were showed the adult mortality of 100% and 98.2% respectively at 3DAT, 90.6% and 84.6% respectively at 7DAT. Whereas the other EFAM had low efficacy. Jindikap-plus and Spider were excellent control effects compared with Acetamiprid WP.

This study was performed to evaluate the contact toxicity and residual toxicity of the 26 commercially registered insecticides against cigarette beetle, Lasioderma serricorne and maize weevil, Sitophilus zeamais adult. Among 26 insecticides, seven insecticides (chlorpyrifos, chlorpyrifos-methyl, fenitrothion, fenthion, phenthoate, cypermethrin,
-cyhalothrin) against L. serricorne adult and five insecticides (chlorpyrifos, chlorpyrifos-methyl, fenitrothion, fenthion, phenthoate) against S. zeamais adult showed perfect mortality,
(ppm) values of those selected insecticides were appeared lowest value on
-cyhalothrin (1.46) against L. serricorne adult and chlorpyrifos-methyl (0.64) against S, zeamais adult, respectively. However, chlorpyrifos-methyl still remain high toxicity until 90th days after treatment against both L. serricorne and S. zeamais adults. From above results, it will be useful information to select insecticides effective against L. serricorne and S. zeamais adults.

A comparative experiment was conducted to investigate the persistence of chlorfenapyr residue and its biological activity to two spotted spider mite, Tetranychus urticae, after treatment of chlorfenapyr suspension concentrate (10% SC) on paprika plants at recommended (2000 times dilution) and double dosage. Biological half-lives of chlorpfenapyr were estimated as 8 and 5 days in leaves and fruits of paprika plants, respectively. While initial deposits of chlorfenapyr residues in leaves at recommended and double dosages were 22.22 and 37.75
at the time of application, its residue decreased to 1.56
at 29 days after treatment, respectively. Residual biological activity of chlorfenapyr SC to T. urticae at recommended dosage lasted for 7 or 15 days on the basis of 24 or 48-hrs mortality test assayed with feeding on excised leaf chlorfenapyr-treated. The control efficacy to the mite showed a good agreement with the persistence of chlorfenapyr residues in leaves.

Control efficacies of mixing of powdery mildew biofungicides with other control agents against major or fungal diseases of cucumber were investigated. Control efficacies against cucumber powdery mildew were quite different according to the kinds of biofungicides applied but those of powdery mildew biofungicides were increased by mixing application of two biofungicides. More than 80% of control efficacies on powdery and downy mildews of cucumber were obtained by mixing application of a powdery mildew biofungicide Bacillus subtilis KB-401 and a downy mildew chemical fungicide dimethomorph. Similarly, control efficacies on powdery and downy mildews of cucumber were 95% and 70% by mixing application of a powdery mildew biofungicide Bacillus subtilis KB-401 and cooking oils and yolk mixture, respectively.

Insecticidal activity of 31 registered insecticides was tested against Metcalfa pruinosa adults. All experiments were conducted at the recommended concentration (ppm) of each insecticide. Among them, 16 insecticides from organophosphates (dichlorvos, fenitrothion, fenthion, methidathion, phenthoate), carbamates (methomyl), pyrethroids (
-cypemethrin, deltamethrin, fenpropathrin,
-cyhalothrin), neonicotinoids (acetamiprid, clothianidin, dinotefuran, imidacloprid, thiamethoxam), and other (endosulfan) showed 100% mortality by spraying on the body of M. pruinosa adults. Dichlorvos, fenitrothion, fenthion, methidathion, phenthoate and endosulfan showed 100% mortality by plant-dipping method. The residual effect was showed 100% mortality in four insecticides (fenitrothion, fenthion, methidathion, phenthoate) at one day after treatment, and three insecticides (fenitrothion, methidathion, phenthoate) were showed the mortality of 90% at three days after treatment.
