“…If these holes are enlarged, the rhizome may be exposed to the external environment, and the applied pesticide may flow through the stem and reach the roots. Pesticide sprayed onto the leaves might have reached the roots through the soil holes [ 21 ].…”

“…Sites 1 and 3 were cultivated in this way, whereas Site 2 was cultivated without any rice straw mat. When cultivated ginseng is covered with rice straw mats, the rice straw absorbs the pesticide flowing into the roots, thereby reducing the pesticide residue levels [ 21 ]. Therefore, the average Site 2 residue levels were higher than those of the other sites.…”

This study determined residual buprofezin levels in fresh ginseng and evaluated their changes during processing. Supervised field trials were conducted at Yeongju, Geumsan, and Goesan, Korea. Buprofezin 12.5% EC was applied to 5-y ginseng in accordance with the Korean good agriculture practice (GAP). Samples were collected at 0, 7, 14, 21, and 30 d after the final application. On day 14 (GAP-equivalent preharvest date), the ginseng was processed to obtain dried and red ginseng. The average buprofezin concentrations on day 0 were 0.076 (Yeongju), 0.055 (Geumsan), and 0.078 mg kg−1 (Goesan). Residual concentrations increased as ginseng was processed into dried and red ginseng. Residue levels in dried ginseng manufactured by hot air drying were higher than in red ginseng obtained by steaming, hot air, and sunlight drying. However, the absolute amount of pesticides decreased by approximately 20–30% as a result of calculating the reduction factor considering the dry yield and moisture content. Therefore, the residual concentration in processed products may vary depending on the processing method, and it is deemed necessary to consider the processing yield and moisture content when evaluating the safety of residual pesticides in dried processed products.

This study was designed to use the safety management data for residual pesticides in imported banana based on the investigation of pesticide residue detection of agricultural products with different origins in the Republic of Korea. From the USA, EU, UK, Japan and Korea from 2007 to 2018, the results of banana residue pesticides were summarized into detected pesticides, number of inspections, number of pesticide detection cases, and the amount of detected pesticide residue. A total of 109 pesticides were detected for the pesticide residue and pesticide detection rate was 4.58% in 206,894 cases. The detection rate was ranged within 10.62-24.62% for chlorpyrifos, imazalil, methyl-bromide, azoxystrobin, carbendazim, pretilachlor and thiabendazole. Among them, chlorpyrifos was detected most often followed by imazalil, azoxystrobin, thiabendazole, bifenthrin and carbendazim. According to the results of monitoring data for bananas in EU, Japan, USA, UK and Korea, the kinds of detected pesticides were 85, 57, 23, 18 and 8, respectively. Azoxystrobin, bifenthrin and chloropyrifos were found in monitoring data of all countries. Fourteen and twelve pesticides were detected in bananas from Costa Rica and Ecuador, respectively. Imazalil and thiabendazole were detected in 16 and 11 origins, respectively. Myclobutanil and iprodione were detected in four and two countries, respectively. In bananas from Costa Rica, azoxystrobin and bifenthrin were detected 11.8 and 9.8%, respectively, and the detection rate of azoxystrobin was 19% in bananas from Colombia. Chlorpyrifos was detected 22.7, 13.3 and 10.8% in bananas from Belize, Colombia and Costa Rica respectively. Myclobutanil was detected in bananas from Colombia and Costa Rica with the rate of 17.9 and 10.4%, respectively.

BACKGROUND: This study was carried out to investigate residual characteristics of diethofencarb during ginseng cultivation and processing, and to establish the maximum residue limits (MRL) of ginseng and its processed products. METHODS AND RESULTS: Supervised field trials were conducted from three fields located at Seosan, Goesan and Jeongeup in Korea. Diethofencarb 25% WP was diluted by 500 times and sprayed 4 times onto the ginseng with 10 days interval. The samples were collected at 80 days after final application. The residual amounts of diethofencarb ranged from 0.074 to 0.460 mg/kg in fresh ginseng, from 0.292 to 0.720 mg/kg in dried ginseng, and from 0.208 to 0.557 mg/kg in red ginseng. These data exceeded the ginseng's MRL, 0.3 mg/kg. The processing factors of diethofencarb in processed products were found to be 2.64 and 1.99, respectively for dried and red ginseng. CONCLUSION: Given the lower residual concentration of red ginseng that goes through a more complicated process than dried ginseng, the residual concentrations of diethofencarb in processed ginseng products were found to be dependent on processing method. Therefore, it is necessary to reconsider the MRL of diethofencarb in fresh ginseng and its processed products.
