Abstract

In order to use in the classification of minor crop for the mutual application of safe use guideline, it was investigated the residue property of fungicide boscalid and fludioxonil at the same time harvest leafy-vegetables, such as spinach, ulgaribaechu, vitaminchae and cheongkyungchae. After pesticides were applied 2 times with 1 week interval in that day of harvest, 2 days, 5 days and 7 days before harvest, vegetables were harvested, and the residue of pesticides was investigated. Base on the residue in that day of harvest, the deposit of spray solution in vegetables was calculated. The deposit of spray solution of boscalid was 253.9 mL/kg in spinach, 83.0 mL/kg in ulgaribaechu, 97.8 mL/kg in vitaminchae, and 88.3 mL/kg in cheongkyungchae, respectively. In case of fludioxonil, it was calculated 157.6 mL/kg in spinach, 67.6 mL/kg in ulgaribaechu, 64.8 mL/kg in vitaminchae, and 66.6 mL/kg in cheongkyungchae, respectively. When the amount of the deposit of both pesticides was compared in leafy-vegetables, it was the highest in the spinach. On the other hand, it was estimated the predicted dissipation curve of pesticides in leafy-vegetables during cultivation. The half-life of boscalid was 5.9 days in spinach, 7.4 days in ulgaribaechu, 4.6 days in vitaminchae, and 4.3 days in cheongkyungchae, respectively. Also, it was estimated half-life in fludioxonil, it was 3.0 days in spinach, 4.0 days in ulgaribaechu, 3.2 days in vitaminchae, and 3.5 days in cheongkyungchae, respectively. The half-life was the longest in the ulgaribaechu. When both pesticides were compared with the residue property, the deposit of spray solution and half-life of dissipation of boscalid were more than those of fludioxonil.

일시에 수확하는 엽채류 중 시금치, 얼갈이배추, 비타민채 및 청경채에 대한 살균제 boscalid와 fludioxonil의 잔류 특성을 조사하였다. 수확일을 기준으로 각각 1주일 간격으로 2회 살포한 후 수확당일, 수확 2일전, 수확 5일전 및 수확 7일전에 시료를 수거하여 잔류량을 조사하였다. 수확당일의 잔류량을 기초하여 작물 중 농약살포액의 부착량을 환산한 결과 boscalid의 경우 시금치에서 253.9 mL/kg, 그리고 얼갈이배추, 비타민채 및 청경채에서는 각각 83.0, 97.8 및 88.3 mL/kg으로 조사되어 시금치에서 가장 많이 살포액이 부착되는 것으로 나타났다. Fludioxonil의 경우도 시금치 157.6 mL/kg, 얼갈이배추 67.6, 비타민채 64.8 그리고 청경채에서 66.6 mL/kg의 부착량을 나타내어 시금치에서 가장 높은 살포액 부착량을 나타내었다. 각 작물에서 boscalid와 fludioxonil의 생육기간 중 농약의 분해소실 정도를 조사한 결과 boscalid의 경우 시금치에서 분해반감기가 5.9일, 얼갈이배추 7.4일, 비타민채 4.6일, 청경채 4.3일로서 얼갈이배추에서 분해 반감기가 가장 길었으며, fludioxonil의 경우에서도 시금치 3.0일, 얼갈이배추 4.0일, 비타민채 3.2일, 청경채 3.5일로 얼갈이배추에서 분해반감기가 가장 길었다. 두 농약의 잔류특성이 비교되었을 때 농약살포 후 살포액의 부착량과 작물생육기간 중 농약의 분해반감기는 fludioxonil 보다 boscalid이 더 많거나 긴 것으로 나타났다.
