A severe blight disease of lily (Lilium spp.) caused by Botrytis elliptica was found in a vinyl house in Taejon for the first time in 1987. Initial symptom of the disease was brown spotting on leaves and stems of the plants. The spots gradually increased in size and coalesced to form bigger spots and blights on the leaves. Plants with severe damage became brown and sometimes died. In the inoculation experiments, the fungus was found to be pathogenic only to lily, but not to pepper, tomato, ginseng, onion and welth onion.

Microbial antagonism between virulent and avirulent isolates of Pseudomonas solanacearum was studied in relation to the control of bacterial wilt of tobacco. In nutrient broth media or in soil, the avirulent isolate of P. solanacearum grew faster than did the virulent one. Inhibitory effect of avirulent isolate against growth of virulent one was negligible in mixed culture of the two isolates. The disease severity of bacterial wilt was significantly reduced when the roots of cultivar BY 4 susceptible to bacterial wilt was dipped in suspension of an avirulent isolate for 6 hours prior to transplanting to the soil infested with virulent bacteria. When the seedlings of tobacco were poured with the suspension of an avirulent isolate onto the soil in pre-planting pots 24 hours before ransplanting, there was a significant reduction in disease severity in the field. However, the reduction was noticed until early July, but after middle of July, no difference between the avirulent isolate-treated and non-treated plants was found in severity of the bacterial wilt.

This study was carried out to investigate the effect of seed disinfectant on leaf blight and smut in adlay. Leaf blight and smut disease in adlay are known to be seed borne. Bjpolan's cojds, pathogen causing leaf blight in adlay, was detected from 32. 7 to 45. 7 % on seeds collected from adlay cultivated farms in Yonchon province. Periods of seed infestation are $0{\sim}7$ days on the variety 'yulmu 1' and $0{\sim}20$ days on 'Yonchon jaerae'. Distribution ratio of seed disinfestation periods was that no disinfestation, $1{\sim}5$days, $6{\sim}10$days and more 11days were 20%, 20%, 45% and 15%, respectively. Frudioxonil W. S. treatment was effective on inhibition of leaf blight and smut disease when treated with infested seeds ; that is, disease control values of the fungicide are 97 and 93.4 percentage, repectively.

본 연구는 하천유역의 중금속을 제거하는데 식물을 활용하기 위해 1994년 7월부터 10월까지 전라북도에 위치한 전주천과 그 주변하천에서 7개 지점을 선정하여 토양층과 물의 Pb, Cu, Zn 및 Fe 등의 함량을 조사하였고 그 주변에 자생하는 고마리, 마름 및 노랑어리연꽃의 중금속 농축량과 부위별 중금속 농축량을 조사하였다. 그리고 재료식물내의 중금속 농축량과 서식지 토양의 중금속 함량과의 관계를 밝히기 위해 재료식물내의 중금속 함유량과 토양의 중금속 함량간의 상관계수를 조사하였다. 실험실 조건하에서 재료식물의 중금속 흡수경향을 조사하기 위해 재료식물 중 고마리를 선정하여 Pb, Cu 및 Zn 등을 여러 농도로 처리한 용액에 고마리의 뿌리부분을 침수하여 재배한 후 그농축량을 측정하였고, 그 결과를 7개 채집지에서 자생한 고마리의 중금속 농축량의 측정치와 비교 분석하였다. 7개 채집지에서 자생한 고마리의 부위별 중금속 농축량은 Pb와 Zn의 경우 줄기<잎<뿌리의 순서로 증가하였고 Cu와 Fe는 잎<줄기<뿌리의 순서로 증가하였으며, 중금별 농축량은 Pb$\leq$Zn의 순서로 증가하였다. 고마리의 배양 실험 결과, 서식지에서 조사된 결과인 잎과 줄기에서 Pb
