Lichen flora of `Backwoon` mountain, Korea, was investigated during the summer of 1998 and 1999 to screen out lichen species which can be used as a biomonitor for atmospheric ozone. The identified foliose or fructicose lichens in the area were classified into 9 families, 20 genera and 34 species. The dominant lichen species in the area were found to be Leptogium sp., Parmelia sp., Parmotrema sp., Phaeophyscia sp. and Cladonia sp. It was also found that lichen species showing a wide range of sensitiveness to air pollution were distributed in `Backwoon` mountain. The Parmotrema austrosinense, P. tinctorum, Certrelia braunsiana and Ramalina yasudae collected in the area were exposed to ozone at the level of 200ppb, 8hr/day in controlled growth chamber for 2 weeks. Malondialdehyde(MDA), hydroperoxy conjugated dienes(HPCD), soluble protein content and OD435㎚/OD415㎚ ratio for phaeophytinization of chlorophyll were measured and a pollution index(PI) was calculated for each lichen. Ozone exposure severely damaged to the lichens in the order of P. austrosinense$gt;P. tinctorum$gt;C. braunsiana $gt;R. yasudae. P. austrosinens easily identified and widely distributed in Korea is likely to be a very useful biomonitor of air pollution, especially for ozone. These results indicate that Korean lichen species can be used as a biomonitor for air pollution to evaluate air quality contaminated with ozone.

This study was carried out to identify the relationship between naturally introduced vegetation on the abandoned coal mine lands and the surrounding forest, and to select the indigenous tree species for the revegetation of the coal mine lands in Taeback, Kangwon Province, Korea. The apparent species in the surrounding forest of Sododong were 9 species of tree layer, 13 species of subtree layer, 23 species of shrub layer and 23 species of herb layer, respectively. The dominant species in Sarijae were 6 species of tree layer, 15 species of subtree layer, 31 species of shrub layer and 25 species of herb layer, respectively. The plant species in the abandoned coal mine land were 31 species in Sododong and 30 species in Sarijae, respectively. The number of plant species in the abandoned coal mine land was smaller than the surrounding forest. The common species of the coal mine lands and the surrounding forest were 6 species(Betula schimidtii etc.) in Sododong and 4 species(B. costata etc.) in Sarijae. It was considered that the species in the coal mine lands introduced from the species of top layer in the surrounding forest. Especially, B. costata in Sarijae showed the edge effect, which regenerates the vegetative community from the boundary area of coal mine land and surrounding forest. Natural revegetation in Sododong was also progressing by the invasion of tree species in surrounding forest, such as B. schmidtii. Consequently, natural revegetation in the disturbed coal mine lands may be related to the species composition of the surrounding forest.

For the effective chemical control to minimize infection of storage pathogens on kiwifruit in the field, this study was conducted to screen alternative fungicides which could be substituted for the fungicides Benomyl WP and Thiophanate-methyl WP registered for the control of postharvest fruit rots of kiwifruit in Korea. Among the 8 fungicides tested, Tebuconazole WP, Iprodione WP and Flusilazole WP showed higher inhibitory effects on the mycelial growths of 3 major pathogens of postharvest fruit rots, Botryosphaeria doth idea, Diaporthe actinidiae and Botrytis cinerea on potato dextrose agar. They also showed control efficiencies as high as those of Benomyl WP and Thiophanate-methyl WP on postharvest fruit rots in the field. They might be good candidates for fungicides for the control of postharvest fruit rots of kiwifruit.

Control efficacies of mixing of powdery mildew biofungicides with other control agents against major fungal diseases of cucumber were investigated. Control efficacies against cucumber powdery mildew were quite different according to the kinds of biofungicides applied but those of powdery mildew biofungicides were increased by mixing application of two biofungicides. More than 80% of control efficacies on powdery and downy mildews of cucumber were obtained by mixing application of a powdery mildew biofungicide Bacillus subtilis KB-401 and a downy mildew chemical fungicide dimethomorph, Similarly, control efficacies on powdery and downy mildews of cucumber were 95% and 70% by mixing application of a powdery mildew biofungicide Bacillus subtilis KB-401 and cooking oils and yolk mixture, respectively.

Lichens, a symbiotic organism of fungi and algae, cause serious damage to national heritages of stone master piece and costly trees for gardening. The present study was conducted to screen effective fungicides against lichen-forming fungi to control the biological agents deteriorating stone heritages and trees. Five commercial fungicides (Fenarimol EC, Etridiazole EC, Iminoctadinetriacetate SL, Difenoconazole+Iminocatadinetriacetate ME and Difenoconazole+Azoxystrobin SC) were tested against the lichen-forming fungi (LFF) isolated from seven saxicolous (Caloplaca sp., Ramalina sp., Xanthoparmelia sp., and Xanthoria sp.,) or corticolous (Parmelia sp.,) lichen species. Preliminary screening test showed that no LFF could grow on the MY (malt-yeast extract) agar medium amended with the recommended concentrations of each fungicide. Further screening was conducted at 1%, 10% and 20% of the recommended concentrations of the fungicides. After 7 week incubation at 15℃ in the dark, Difenoconazole+Iminocatadinetriacetate ME and Difenoconazole+Azoxystrobin SC completely inhibited the fungal growth of all the tested LFF, even at 1% of the concentration. Two fungicides of Fenarimol EC and Iminoctadinetriacetate SL exhibited a moderate inhibition activity at the lower concentrations. Etridiazole EC was less effective in the fungal growth inhibition than the other four fungicides. The results suggested that lichens colonizing on precious stone heritages and trees can be eradicated by applying Difenoconazole+ Iminocatadinetriacetate ME and Difenoconazole+Azoxystrobin SC even 1 % of the recommended concentrations. Selected fungicide application at such a low concentration will facilitate the chemical use to prevent and preserve stone heritages from biological deterioration induced by lichens and the allied microbes.
