In order to elucidate the behavior of the fungicide hexaconazole (1-(6-chloro-3-pyrldyhnethyl)N-nitroimidazolidin-2-ylideneamine) in carp (Cyprinus carpio L.), carps were exposed to [
]hexaconazole at a predicted environmental concentration (PEC) of 0.32 mg
for 4 days under static conditions. Hexaconazole in water was absorbed into carps to reach the maximum concentration 2 days after exposure. The amounts of the [
]hexaconazole and its metabolites absorbed in gall were much higher than those in the other organs and especially those in gall 2 days after exposure were 25 and 67 times higher than those in liver and kidney, respectively, strongly suggesting that biliary excretion involving enterohepatic recirculation could be an import route for the elimination of hexaconazole absorbed in carps.

It is well known the functional foods are very useful to prevent serious diseases and promote health. Therefore, they are often called as nutraceuticals, designer foods, and pharmafoods, etc. Most of foods have diverse functions because they provide nutrients, energies and fibrinoid materials. When foods are taken in the body, they promote the biological defense system against diseases through the supply of the essential or healthy materials to human being's organs. The mode of action and functional foods in human body have not been clarified yet. Antioxidant is known as one of the therapeutic aids which can be reduced pesticide poisoning. Onion has a strong antioxidant effect. This study was carried out to elucidate an antioxidant function of onion by determination of superoxide dismutase in liver, lung, serum of male rat administered by intraperitonial injection of 0, 2,
cblorpyrifos after administrated orally with onion for 6 weeks. Damage of liver and kidney was also investigated by biochemical analysis of serum(AST, ALT, BUN/Creatine ratio). SOD(superoxide dismutase) activity of onion-administrated group is higher than control group. In liver and lung, SOD activity of onion+cblorpyrifos administrated group is higher than only chlorpyrifos administrated group. BUN/Creatinine ratio of onion+chlorpyrifos administrated group was decreased compared with only chlorpyrifos-administrated group.

This study was carried out to indicate the status of agricultural environment in Yangpyong area which is special protection area for tap water in Han river during three years(
). The main study was on pesticide monitoring, analysis of pesticides in Bokpocheon water and soil. Water in this small river for supplying to the rice was found nine pesticides residues, ranged from 0.1 to 22.7 ppb, similar patterns from survey conducted in National Institute of Agricultural Science and technology, Soil in rice paddy has also low levels of eleven pesticide residues, ranged from 0.002 to 0.55 ppm.

This survey was performed to elucidate whether pesticide can cause the non-spinning syndrome of silkworm, Bombyx mori in Yecheon and Sangju 2002. We primarily focused to Insect Growth Regulator Pesticides(IGR) used in that areas. In the result of the survey to the retail pesticide store at Yecheon and Sangju, seven pesticides of the total 12 IGR pesticides sold were used during spring sericuitural season. 7 pesticides might effect on silkworm in consideration of possibility of exposure according to the characteristics of used amount, spray drift, volatility and treatment time. Five chitin synthesis inhibitor involving diflubenzuron of 7 IGR pesticides were known as very toxic to silkwork after exposure by skin and feeding but no non-spinning syndrome was observed from several papers. Methoxyfenozide and tebufenozide also has used at sericultural season, but are ecdysone agonist. One of the most feasible suspect of non IGR pesticide, was molinate in consideration of its volatility property and wide spread use in the sericultural area. But it's symptom after exposure of molinate was not the same as the non-spinning syndrome broke out at the sericultural farm in Yecheon and Sangju.

The reproduction toxicity of several pesticides on two Korean water flea was investigated to develop a new standard species used for ecological risk assessment of pesticide. Moina macrocopa and Daphnia sp. were exposed to 4 different types of pesticides over 10 and 21 days, respectively. No-ohserved effect concentration (NOEC) for synthetic pyrethroid, fenpropathrin on Moina macrocopa and Daphnia sp. were 0.17 and
, respectively. Diazinon, carbofuran and myclobutanil were in the order of their reproduction toxicity to cladocerans tested. There were large differences between Moina macrocopa and Daphnia sp. in their susceptibility to fenpropathrin, diazinon and carbofuran except myclobutanil. Daphnia sp. is more sensitive than M. macrocopa to pesticides tested. Therefore Daphnia sp. may be a good surrogate species to assess the reproduction effect of pesticides on aquatic invertebrates. M. macrocopa also be a good surrogate species because it is one of the most abundant cladocera in agricultural environment, especially rice paddy in Korea. In addition to it's ecological importance of wide spread distribution, it has also economical importance to make possible to shorten period for reproduction test using M. macrocopa due to it's short life cycle.

In order to evaluate the toxic effects of butachlor, a herbicide widely used for control of weeds in paddy field, on medaka (Oryzias latipes), acute toxicity tests for five developmental stages and early life stage toxicity test of were conducted. As the results of acute toxicity test,
for 1 day, 1 week, 2 weeks, 2 months and 5 months after hatching of O. latipes were 0.68, 0.52, 0.38, 1.09 and
, respectively. This indicated that the most sensitive stage was 2 weeks after hatching. The early life stage toxicity test showed that no statistically significant hatching period and hatching success of embryo was observed at all concentrations of butaclor. However, 0.05 and
of butachlor showed statistically significant post hatching survival with p<0.1. Abnormalities of larva were 2.1, 2.3 and 10% at 0.025, 0.05 and
of concentration, respectively. They showed abnormal vertebral axis, craniofacial alteration and retarded yolk-sac resorption. The total length and weight were decreased depending on butachlor concentration the end of test. Weight of larva was showed more sensitive toxic indicator than total length. The toxicological responses of O. latipes to butachlor expressed as LOEC(lowest observed effect concentration), NOEC(no observed effect concentration) and MATC(maximum acceptable toxicant concentration) values were 0.025, 0.013 and

The acute toxicity of several pesticides on 4 Korean water flea was investigated to develop a new standard species used for ecological risk assessment of pesticide. Four Korean freshwater cladocerans, Daphnia obtusa, Daphnia sp., Moina macrocopa and Simocepholus vetulus were exposed to five different pesticides during 48 hours to compare their sensitivity with a standard test species, Daphnia magna, endorsed formally by the major international organizations. The synthetic pyrethroid, fenpropathrin was the most toxic pesticide to cladocerans. Diazinon, carbofuran, iprodione and myclobutanil were in the order of their toxicity to cladocerans tested. There was no consistent difference in sensitivity to five pesticides for four Korean cladocerans tested. In conclusion, the ecological risk assessment using single species toxicity referred to base set data should not be enough to protect to every species in the field environment.

Four sulfonylurea(SU)-resistant Monochoria vaginalis(M. vaginalis) accessions were tested for levels of resistance to four SU herbicides which have been widely using in paddy fields of Korea, based on whole plant response and sensitivity of the target enzyme, acetolactate synthase(ALS). The resistant Naju, Nonsan and Gimje accessions were not affected to the survival by treatment with recommended dose of all SU herbicides tested. The
values for the Naju, Nonsan and Gimje accessions were 8- to 33-fold, 8- to 30-fold and 7- to 32-fold higher to recommended doses of all SU herbicides tested than the susceptible Cheongdo accession, respectively. However, the
values for Kimhae accession displayed an intermediate response and was only 4-to 13-fold more resistant than the susceptible accession. The ALS
values for the Naju, Nonsan and Gimje accessions were 25- to 66-fold, 9- to 26-fold and 10- to 24-fold higher to recommended doses of all SU herbicides tested than the susceptible Cheongdo accession, respectively. However, the
value for Kimhae accession was 4- to 9-fold more resistant than the susceptible accession, as determined by
values of ALS.

In order to select the coating materials to perilla seed for reducing endosulfan residue greenhouse soil, this study was conducted to develop seed coating method and materials and also to evaluate the effects of seed coating on germination and color contrast between soil and perilla seed for convenient sowing work. Talc and kaoline were selected as seed coating materials because easy coating and better color contrast than shell powder or lime. Water was more effective on germination compared to alcohol, com oil and spray sticker as adhesives for seed coating.

This research was carried out to propose the Korean method for estimating the agricultural occupational pesticide exposure level in orchard. The UK-POEM (UK-Predictive Operator Exposure Model) was proposed as a bench-marking model and analysed its performance properties. To extrapolate the Korean agricultural conditions, application equipment, application method, work rate per day, application volume and spraying time of pesticide was surveyed for Korean 204 orchard farmhouse. This survey indicate that the major application equipments are speed sprayer(64.9%) and motor sprayer(33.9%). When they spayed the pesticide with a speed sprayer, they worked for more than 4 hours on area of 4 ha per day. In case of using motor sprayer, they worked for more than 4 hours on area of 1 ha. Based on the above survey result, Korean method for estimating the pesticide exposure level of agricultural worker was proposed finally.

In order to set ADIs for pesticides registered for use in Korea, an analysis of guidelines on setting ADIs and ADIs established by international bodies and advanced countries was conducted General guidelines on the derivation ADIs are very similar among regulatory authorities. However, there were large differences in the ADIs' setting status and ADI values set for some individual pesticides. ADIs were established for 213 pesticides in UN, 332 in USA, 230 in Japan, 219 in UK and 435 in EU and Australia. Of the established ADIs in other countries, 87 to 252 pesticides were the pesticides registered in Korea depending countries. The number of lowest ADIs depending countries was 32 in USA, 23 in Japan, 6 in EU and Australia. The key target organs and endpoints used for setting ADIs were in the order of enzyme inhibition, body weight change and adverse effect on liver. The number of ADIs used for setting MRLs in Korea was high in the order of JMPR, Japan and USA. ADIs of EU and JMPR had highest similarity among bodies investigated. By referring to the guidances investigated at this study, guideline for setting ADI and ADIs for 64 pesticides registered in Korea were proposed.

Surveying, laboratory and field trial were performed to elucidate the causes of non-spinning syndrome of silkworm, Bombyx mori, abnormal symptoms of silkworm instars observed in certain sericultural fanning region. Mortality and growth of silkworm was still influenced by feeding the mulberry leaves sprayed with 10,000 fold diluted solution of standard spray of diflubenzuron WP (25%). Mortality and growth of silkworm fed with diflubenzuron-sprayed mulberry leaves with recommended spray solution were entirely affected even six weeks after spraying irrespective to the instars. Larval period of 5th instar and cocooning duration of silkworm was not affected in case 50m of buffer zone has maintained in near-by orchard field sprayed with diflubenzuron WP (25%). However, survival rate of pupae was not influenced in case 100 m of buffer zone has kept. Insect growth regulating insecticides were required to keep a certain distance of buffer zone when sprayed with water-diluted solution, 100 m from the application site at least in order to prevent contamination of the spraying drift by the chemicals.

It was the investigated the response to metalaxyl of Phytophthora capsici isolates collected in 2005 and 2006. With effective concentrations (
) of metalaxyl causing 50% growth inhibition, resistance baseline was determined as more than
. Based on the resistance baseline, isolation frequency (%) of P. capsici resistant to metalaxyl was 29.0% and 218% in 2005 and 2006, respectively. Among the isolates of P. capsici obtained in 2006, the isolation was variable; 33.3% in Chungnam, 26.3% in Chungbuk and 11.1% in Gyeongbuk. Two isolates of metalaxyl-sensitive (MS) and too isolates of metalaxyl-resistant (MR) P. capsici were selected and then used to investigate the activity of metalaxyl to their development stages. Even though there was a difference in mycelial growth inhibition by metalaxyl between MS and MR isolates, the fungicide was not active or nearly to sporangium germination, zoospore release, and zoospore germination of both MS and MR isolates. However, the fungicide showed weak activity against sporangium germination and zoospore release of P. capsici, not related with its resistance. Also, it was not inhibitory to zoospore germination of both resistant and sensitive isolates. In a greenhouse test, it showed 100% of control value against P. capsici 06-86 sensitive to metalaxyl, when it was applied by soil-drenching at
. However, 06-130 and 16-155 resistant to metalaxyl showed less than 20% of control value.

Nine plant growth regulators (PGRs) were tested for in vivo antifungal activities against on rice blast. They showed higher in vivo antifungal activities when they were applied on rice plants by soil drench rather than foliar spray. Except for 2,4-D at
, the others showed a very low or no activity against the disease in foliar spray applications. In contrast, 2,4-D, indole butyric acid (IBA) and triiodobenzoic acid, at
, showed control values of 98.9, 97.8 and 88.9% in soil drench applications. Furthermore, the control activity of IBA was dependent on its concentration against rice blast; IBA suppressed the development of rice blast by 71.7% at
and 85.8% at
. IBA also controlled the development of rice blast on adult plants by 63.9% at a dosage of 2.56 kg/10a. The results revealed that IBA has a good activity against rice blast when it is applied by soil drench.

Mitochondrial 16S DNA sequences of Bemisia tabaci which were collected on rose greenhouse of Iwol and Jinchen in Chungbuk and red pepper field of Miryang, Gyeongnam, were analyzed. The mtCOI PCR product of B. tabaci collected on red pepper field of Miryang were digested with EcoT14I (Sty I) into two fragments 555bp and 311bp, while the PCR product of B. tabaci collected on rose greenhouse of Iwol were digested with Sty I into two fragments of 560bp and 306bp. As a result, B. tabaci collected on red pepper reveal biotype Q and those on rose greenhouse was biotype B. These was difference between two biotypes in insecticide susceptibility, and the biotype B was more susceptible than biotype Q. As a result of foliar systemic test, root-uptake systemic test and residual effect, the biotype B was more susceptible. In case of inhibition effect on enzyme activities of fenitrothion (organophosphorous) and fenothiocarb (carbamate), those of biotype Q was higher than those of biotype B. These results indicate that biotype Q was more resistant than biotype B against 12 insecticides.

The major fungal diseases which effecting garlic storage are blue mold and dry rot, caused by Penicillium hirsutum and Fusarium oxysporum, respectively. In order to reduce the damage by the pathogenic fungi, here we report the effects of 11 fungicides tested to reduce spoilage during storage of garlics. In the in vitro antimicrobial activity test, the fungicides, diphenylamine, prochloraz and tebuconazole showed 0.3, 2.2, and 1.3 nun inhibition zone to F. oxysporium, and cyprodinil, diphenylamine, fenbuconazole, hexaconazole, penconazole, prochloraz, propiconazole, pyrimethanil and tebuconazole exhibited 0.2, 2.4, 0.8, 0.4, 1.2, 1.5, 1.2, 0.4 and 1.5 mm to P. hirsutum, respectively. To test the in vivo control effect, when the diphenylamine, prochloraz, and tebuconazole were treated by standard concentration, the fungal mycelium of F. oxysporium started to grow 5 days after inoculation, and 80, 63.3 and 83.3% of the inoculated cloves are infected 11 days after inoculation. When the tebuconazole were treated by standard concentration, the P. hirsutum was completely inhibited the growth of the fungi. In case of diphenylamine, penconazole and propiconazole treatment, the P. hirsutum was observed 7 days after inoculation and
of the cloves were infected 11 days after inoculation. When cyprodinil, prochloraz and pyrimethanil were treated, pathogens occurred 5 days after inoculation and
of the cloves infected 11 days after inoculation. Three fungicides such as diphenylamine, prochloraz and tebuconazole also suppressed remarkably the infection and growth of F. oxysporium and P. hirsutum on garlic when both of the pathogens are inoculated after the garlic cloves were dipped for 10 min in the suspension of each agrochemical. Overall, diphenylamine, prochloraz and tebuconazole showed effective control efficacy on dry rot and blue mold There was significant correlation between in vitro and in vivo assay in diphenylamine and prochloraz to F. oxysporum and cyprodinil, prochloraz and pyrimethanil to P. hirsutum.
