This study was investigated to review the potentials of irritation and skin sensitization of active ingredients and end-use products of pesticides for pesticide registration, prediction of irritation and sensitization, and data requirements for other purposes. Pesticide irritation and sensitization referred to the Pesticide Manual(14th edition), while toxicity was evaluated based on the data submitted by the pesticide registrant. Totally 148 active ingredients and 149 end-use products were analyzed to compare the positive response, formulation type, and correlation between active ingredients and products. Among active ingredients, ratio of positive response to skin irritation, eye irritation, and skin sensitization were 18.8, 47.0 and 20.6% respectively. While, positive response to skin irritation, eye irritation, and skin sensitization of the products were 14.9, 38.9 and 23.6%, respectively. Emulsifiable concentrate showed the highest positive response among formulation types showing skin irritation 31.3%, eye irritation 81.3%, and skin sensitization 31.3%. On the other hand granule type showed the lowest response with skin 4.8, eye 14.3 and sensitization 14.8%. There was no correlation by active ingredient content on irritation and sensitization of products. However, both active ingredients and products showed same positive response were skin 73.1%, skin sensitization 66.2%, and eye irritation 44.7%. By the these results, correlation between technical grade of active ingredients and end-use products would be use for pesticide management at the screening stage, especially skin irritation and skin sensitization.

This study was conducted to monitor the current status of pesticide residues in agricultural products before auction at whole markets in Busan area from March 2006 to December 2008. Of the 7,237 samples that were analyzed by multiresidue methods, 1,164 samples (16.1%) had pesticide residues and 231 samples (3.2%) exceeded the maximum residue limits (MRLs). 181 samples of the 231 samples exceeding MRLs were applied to the tentative limits because the use of the pesticides for the agricultural products was not established against the MRLs in the Korea Food Code, and it is equivalent to 78.4%. The order of pesticides exceeding MRLs was endosulfan, procymidone, chlorothalonil, ethoprophos, chlorpyrifos, diethofencarb, kresoxim-methyl and EPN. Of 211 samples with two or more pesticides residues, the residues exceeded the MRLs in 80 samples and it is equivalent to 37.9%. This study results suggested that pesticide residues exceeding MRLs could be attributed to the use of inapplicable pesticides for agricultural products and the use of two or more pesticides.

Fomesafen is a selective herbicide, and used to control annual and perennial broad-leaf grass on soybean and fruit fields in USA and China, but not introduced in Korea yet. So, MRL (Maximum Residue Level), and analytical method of fomesafen were not establishment in Korea. Therefore, this experiment was conducted to establish a determination method for fomesafen residue in crops using HPLC-UVD/MS. Fomesafen residue was extracted with acetone from representative samples of five raw products which comprised hulled rice, soybean, apple, green pepper, and Chinese cabbage. The extract was diluted with saline water, and dichloromethane partition was followed to recover fomesafen from the aqueous phase. Florisil column chromatography was additionally employed for final clean up of the extract. The fomesafen was quantitated by HPLC with UVD, using a Shiseido CAPCELL-PAK UG C18 column. The crops were fortified with fomesafen at 3 levels per crop. Mean recovery ratio were ranged from 87.5% for a 0.4 ppm in hulled rice to 102.5% for a 0.4 ppm in apple. The coefficients of variation were ranged from 0.6% for a 2.0 ppm in hulled rice to 7.7% for a 0.04 ppm in green pepper. Quantitative limit of fomesafen was 0.04 mg/kg in representative 5 crop samples. A LC/MS with selected-ion monitoring was also provided to confirm the suspected residue. Therefore, this analytical method was reproducible and sensitive enough to determine the residue of fomesafen in agricultural commodities.

We investigated five neonicotinoid pesticide residues (acetamiprid, clothianidin, imidacloprid, thiacloprid, thiamethoxam) in fruit vegetables and estimated the exposure of neonicotinoid pesticide residue through fruit vegetable consumption using a deterministic approach. Two hundred forty samples of eight fruit vegetables cultivated in Korea were analyzed for their pesticide residue contents. Acetamiprid had the highest detection frequency and the highest residue level in pepper. However, all pesticide levels detected didn't exceed national MRLs. The results using a deterministic approach showed that for chronic and acute study of all neonicotinoid pesticide residues, the exposure was about 50 times lower than toxicological endpoint values. It is necessary to understand that the exposure assessment in this study using a probabilistic approach should be regarded as a important knowledge in the decision-making process.

The aim of this study is to investigate the exposure assessment of Korean consumers to five neonicotinoid pesticides in fruit vegetables cultivated in Korea, using a probabilistic approach. We used five neonicotionid pesticides residues(acetamiprid, clothianidin, imidacloprid, thiacloprid, thiamethoxam) data in fruit vegetables reported by Rural Development Administration for the 2009 monitoring programme. Total exposure of five neonicotinoid pesticides for Korean consumer ranged from 0.087 to 0.236
/kg/day at the
percentile values of total exposure of five neonicotinoid pesticides by probabilistic approach were lower than those by deterministic approach, although mean values of total exposure by probabilistic approach were similar with those of total exposure by deterministic approach. Total exposure to acetamiprid residue may be mainly due to the exposure to acetamiprid through the consumption of strawberry. Also, acetamiprid residues in strawberry were considered as much more contributory factor to total exposure of acetamiprid than consumption data of strawberry. This contributory properties of acetamiprid were similar with those of all other neonicotinoid pesticides, excluding thiacloprid.

This study was carried out to estimate the risk of pesticide operators who use high toxicological pesticides. The class II (highly hazardous) pesticides registered in korea were 15 products, and 11 products were spray type pesticides at orchard file in 2009. The using information based on the pesticide label and the data searched through survey of actual condition on pesticides were used for calculate the pesticide operator exposure dose. The risk quotients of these pesticides against the pesticides operator were calculated as devide pesticide exposure dose by reference dose which were presented by EFSA (European Food Safety Authority), JMPR (Joint FAO Meeting on Pesticide Residues), and US/EPA (United States Environmental Protection Agency). Omethoate showed the highest risk quotient and the values were 338 and 75 when the operator spray using speed sprayer and motor sprayer respectively. Risk quotients of all class II pesticide were above 1. This result means that the risk potential of these pesticides are very high.

Six populations of the diamondback moth, Plutella xylostella, were collected from the different national areas for resistance and reared in laboratory for two sensitive population. These populations of P. xylostella were examined the developed resistance against commercial products of Bacillus thuringiensis. There were 3 products with B. thuringiensis subsp. kurstaki including Tyuneup
and 2 products with B. thuringiensis subsp. aizawai including Tobagi
. The sensitive population of diamondback moths were provided from National Academy of Agricultural Science (NP) and Highland Agriculture Research Center (GR population) and field populations were caught from 6 different national areas. Resistance against Tyuneup
was developed 4.8 and 2.5 times in SP and HS compared with GR population of diamondback moth, respectively. In case of Geumulmang
, it was developed 9.9 and 6.8 times in SP and NM population compared with NP population, respectively. Otherwise, Tobagi
was showed higher resistance in HS than any other population compared with GR population, however, Scorpion
that is a same strain with Tobagi
, was showed only double resistance to SP population. It was supposed that the development of resistance to B. thuringiensis might be caused by the continuous application of the specific commercial product at the specific area. So, we need to use the commercial products of B. thuringiensis in rotation with different B. thuringiensis strains. In the other hand, when HS population with highest resistance were reared in laboratory, their resistance ratio was rapidly dropped to 1.1 times at second generation. We have to examined the resistance mechanism of the diamondback moth to B. thuringiensis strains.

A field investigation was carried out for two years to analyze yield loss due to soybean anthracnose caused by Colletotrichum truncatum and to determine its economic threshold limit. Anthracnose severity in terms of % diseased pods was negatively correlated with yield, number of normal seeds per plant and number of pods per plant, and positively correlated with % abnormal seeds with correlation coefficients of -0.85, -0.78, -0.64, and 0.80, respectively. A simple linear regression model was obtained as Y=-1.7781X+164.22 with
=0.8092, when the soybean yields (Y) were predicted using anthracnose severity (X) as an independent variable. The yield levels could be predicted as high as 80.92%. Based on this equation, spray threshold without economic considerations was estimated as 6.9 in % pods infected with anthracnose. Economic threshold limit and economic spray threshold able to compensate the costs of fungicide sprays were determined as 11.9% and 9.5%, respectively.

Nematicidal activity against pine wood nematode, Bursaphelenchus xylophilus, was tested in the pot and field by the treatment of microbial formulation after media optimization. The optimized media composition was glycerol 10 g, soybean meal 10 g, NaCl 1 g,
0.125 g per liter and microbial complex formulation was made with liquid and powder type. Most effective antibiotics against symbiotic microorganism with nematode, kanamycin, was added to the formulation. The control effects against pine wood nematodes were checked by pot test and field test. In the result of treatment by trunk injection, five times treatment was more effective than one time and the treatment with the formulation of concentrated culture supernatant was the most effective in the nematicidal activity showing below 10% mortality in pine tree.

S59-4 isolate was evaluated as a potential biocontrol agent using in vivo wounded garlic bulb assay. When the spore suspension (
) of Penicillium hirsutum was co-inoculated with cell suspension of S59-4 isolate on wounded garlics, the isolate showed high suppressive effect to disease development. The isolate was identified as Pantoea agglomerans S59-4(Pa59-4) through Biolog system. Furthermore, soaking garlic bulbs in the suspension of Pa59-4 significantly reduced garlic decay caused by P. hirsutum. The optimal concentration of Pa59-4 for controlling garlic blue mold was
. And suppressive effect of Pa59-4 on garlic storage decay reduced as inoculation concentration of Penicillium hirsutum increased. In addition in order to investigate population dynamics of Pa59-4 on application site of garlic cloves, two antibiotic markers, pimaricin and vancomycin were selected. Bacterial density of Pa59-4 on the wounded garlic cloves increased continuously both under room temperature condition and low temperature condition until 30days after application of Pa59-4, meanwhile that of Pa59-4 on intact garlic cloves increased until 15days after application of Pa59-4 and thereafter decreased continuously. Two culture media for mass-production of Pa59-4, LB medium and TSB medium, were selected. By-product of bio-fungicide formulated by mixing white carbon and bacterial suspension of Pa59-4 suppressed by 40 to 50% garlic blue mold. Above results suggest that Pa59-4 be a promising control agent against garlic blue mold.

This study was performed to investigate the hatching rate and eggs period until hatching in the laboratory against lantern fly, Lycorma delicatula eggs with different collecting date of eggs, and the susceptibility of 26 insecticides to the eggs, 1st and 2nd nymphs of Lycorma delicatula. The eggs of L. delicatula were increased the hatching rates as passed collecting date of eggs, and shorten in eggs period until hatching. By screening the susceptibility of 26 insecticides to the eggs, 1st, and 2nd nymphs, chlorpyrifos (312.5 ppm) showed the perfect inhibition effect of hatching against the eggs, however, the other insecticides did not show that effect. According to the collecting date of eggs, chlorpyrifos bioassayed the inecticidal effect with different concentration (625 ppm at double conc., 312.5 ppm at recommended conc., and 156.3 ppm at half conc.). The eggs collected from Apr. 20th 2010, were showed the inhibition effect of hatching over 94.5%, but the eggs collected from May 10th, 2010 were showed the inhibition effect of hatching as 86.7, 71.1, and 47.1%, respectively. However, hatched eggs were all killed perfectly within 24 hours. At recommended and half concentrations, the eggs collected from 15, May, are decreased the effect as 48.6%, 53.7%, respectively, and the mortality of eggs hatched also decreased as 61.0 and 22.0%, respectively, however, double concentrations did not show the changes. From the above results, it will be anticipate to show the higher mortality against the eggs of L. delicatula when treated chlorpyrifos until late-April.

Methyl (E,E,Z)-2,4,6-decatrienoate is the aggregation pheromone of brown-winged stink bug Plautia stali (Hemiptera: Pentatomidae). Attractiveness of the pheromone synthesized in Korea was compared with that of synthesized in Japan in the field. A lure filled with hexane was used as a control treatment. Catches in trap baited with Korean pheromone was significantly higher than that baited with Japanese one only in one orchard out of three sweet persimmon orchards in 2008. However there was no difference in trap catches between Korean and Japanese pheromones at three sites in 2009. Gas chromatography analysis showed that the components of both pheromones were not different each other. Monitoring of P. stali seasonal fluctuation using Korean pheromone showed that the bugs were most captured in August, 2008 and in September, 2009.

The acaricidal activity of cyenopyrafen on the tea red spider mite, Tetranychus kanzawai was evaluated in laboratory and field studies. In the laboratory, cyenopyrafen was highly effective against egg, larva, protonymph and adult female of T. kanzawai. In surviving adult females of T. kanzawai exposed to cyenopyrafen, we observed significant reduction in reproduction and no egg hatch. Effectiveness of cyenopyrafen against adult female of T. kanzawai on bean leaves was lasted for 15 days at treatments of 125 and 83.3 ppm. In a field study, cyenopyrafen exhibited excellent activity to mixed developmental stages of T. kanzawai. Based on the results, cyenopyrafen could be used for the control of T. kanzawai and treatment of this acaricide at 83.3 ppm was recommended as the field rate.

Two insecticides, fenobucarb (36, 12 ppm) and imidacloprid (0.7, 0.4 ppm) were treated on rice seedling roots by root uptake method with different dipping time (1, 4, 8, 12, 16, 20, 24 hrs). This study was performed to elucidate the correlation between insecticidal activity and feeding behavior of Nilaparvata lugens using EPG (electrical penetration graph). EPG waveforms are recorded for 4 hours and classified into six waveforms. In the correlation between root uptake and corrected mortality, both insecticides showed higher corrected mortality as higher doses and as longer root uptake times. In the analysis of waveforms, N. lugens showed longer nonprobe time but shorter phloem feeding time at a higher dose. It was also showed the same result as longer the root uptake times. Therefore, it showed the correlation between insecticidal activity by root uptake time and both EPG waveforms (non-probing time and phloem feeding time).
