아시아 주요국으로 ‘Shine Muscat’ 포도를 수출하기 위하여 수출대상국의 농약잔류허용기준(MRL)에 적합하며 안정적이고 우수한 품질의 포도를 생산할 수 있는 포도 병해 방제력을 개발하고자 하였다. 경북 경산과 상주 지역의 간이비가림시설에서 재배되는 ‘Shine Muscat’ 포장에서 수출 대상국에서 허용 된 약제 중에서 포도 재배에 많이 사용되는 살균제를 선발하였고, 재배 기간 동안의 병해 발생을 방제하기 위하여 개화전부터 성숙기까지 10-11회 살포하였다. 2년에 걸쳐 약제를 살포하고 수확 전 병해 발생 여부를 조사하고 수확 후에는 과실의 품질 특성과 잔류 농약을 분석하였다. 갈색무늬병, 노균병, 탄저병이 발생하였으며, 2019년 2번 처리구에서 전체적으로 82% 이상의 방제가를 나타내었다. 과실 품질 특성은 지역별로 약간의 차이를 나타냈고 모든 처리구에서 농약 잔류량은 0.00-0.20 mg/kg 수준으로 주요 수출국의 MRL 이하로 검출되었다. 본 연구에서는 최근 수출량이 증가하는 ‘Shine Muscat’ 포도 재배에 활용할 수 있으며 안전한 수출용 포도를 생산할 수 있는 병해 방제력을 개발하였으며, 국내의 포도 수출 농가에 도움이 될 것으로 생각된다.

Background : Ginseng is a perennial plant and damaged by various diseases and insect pests. The damage lowers harvest and quality. In particular, gray mold rot occurs to plants of every year, growth duration, and hibernating stage, and decays leaves, stems, and roots, lowering the amount of harvest. This experiment was conducted with the aim of effectively preventing gray mold rot, and other major diseases such as anthrax and spotting disease, and establishing chemical control system. Methods and Results : This experiment was conducted in three areas including Geunsan-gun, Yesan-gun, and Sejong city. As for the procedure of medical treatment, from the end of April to early May of germination period, Fludioxonil and Pyraclostrobin were used. From the mid-May to the end of July of growth period, Difenoconazole, Iminoctadine tris (albesilate), Cyprodinil, Metconazole, Fluazinam, and Pyrimethanil were used. From August to September, non residualizing polyoxinB + mancozeb was used. In November of hibernating stage, Fenhexamid and Carbendazim/diethofencarb were used. As for the interval, from the end of April to the end of July the interval was 10 days, in August and September once a month, and twice in every ten days in November. The chemical control system effect was compared with conventional prevention. When chemical control system was used, stem spotting disease occurred at a lower rate of 0.34% than 1.2% of the conventional method. Leaf spotting disease occurred at a lower rate of 1.4% compared with 7.1% of the conventional method, and anthrax occurred at a lower rate by more than 10% than the conventional method. Stem gray mold rot occurred at a rate of 4.1% when the conventional method was used, but the rate stood at 5.3% in Geumsan, 8.9% in Yesan, 2.3% in Sejong when the prevention method was used, which suggest the chemical control system was effective. Conclusion : When chemical control system was applied to prevent major diseases of ginseng, spotting disease, anthrax, and gray mold occurred at lower rates compared with the case where the conventional method was used. The finding is that the chemical control system can be utilized to prevent major diseases of ginseng.
