Conidiomata of the Rosellinia necatrix were induced in axenic culture under near ultraviolet light radiation. Pieces of sterilized Japanese pear twigs were placed on the 7 days-old oatmeal agar culture in plates. The plates were further incubated for 5 days and then illuminated by under near ultraviolet light radiation. Synnemata were developed on twigs in 19 out of 20 isolates tested within 5 weeks, and conidia were observed in 12 out of the 19 isolates. The synnemata and conidia produced were morphologically identical to those of Dematophora necatrix.

The fungus Cylindrocarpon destructans is the cause of root rot in many ginseng production areas in Korea. Atotal of 57 isolates of C. destructans were recovered from diseased roots in a survey of ginseng–growing fieldsfrom 2011-2012. Among these isolates, 37% were classified as highly virulent (causing lesions on unwoundedmature roots) and 61% were weakly virulent(causing lesions only on previously wounded roots). Radialgrowth of highly and weakly virulent isolates on potato dextrose agar was highest at 20oC and there was nogrowth at 35oC. Mycelial mass production was significantly (P = 0.05) lower at pH 7.0 compared with pH 5.0. To study the effects of pH (5.0 and 7.0) and wounding on disease development, ginseng roots were grownhydroponically in nutrient solution. Lesions were significantly larger (P < 0.01) at pH 5.0 compared with pH7.0 and wounding enhanced disease by a highly virulent isolate at both pHs. In artificially infested soil, 2-yearoldginseng roots were most susceptible to Cylindrocarpon root rot among all root ages tested (1 to 4 years)when evaluated using a combined scale of disease incidence and severity. Root rot severity was significantly(P<0.05) enhanced by increasing the inoculum density from 3.5 × 102 cfu/g of soil to 2.0×103 cfu/g of soil.

This research was carried out to elucidate the causes of fruit skin browning in ‘Mansu’ pear for the last 2 years. It was observed that skin browning was induced even by the small mechanical injury produced during grading and packing for the market supplies after harvest on the fruits of ‘Mansu’ pear. The incidences of fruit skin browning in pears treated with artificial mechanical injuries were investigated between ‘Niitaka’ and ‘Mansu’ pears. The results showed that fruits of ‘Mansu’ are more susceptible to skin browning than those of ‘Niitaka’. We also found that the epidermis of fruits in ‘Mansu’ pear was thinner than that of ‘Niitaka’, and that there was lower incidence of fruit browning in epidermis of pears with high chlorophyll content than those with low chlorophyll content. The skin browning in fruits could be considerably reduced by sorting and grading them wrapped with paper bags for the fruits of ‘Mansu’ pear.

Bilateral Sequential Pneumolabyrinth Resulting from Nose Blowing

이중섭,권세영,김지희,김형종 대한청각학회 2015 Journal of Audiology & Otology Vol.19 No.3

Pneumolabyrinth describes a condition with entrapped air in the labyrinth and usually occurs in temporal bone fractures that involve the otic capsule. While sporadic cases of bilateral pneumolabyrinth have been reported, cases lacking head trauma are very rare. We report the case of a 43-year-old man who had sudden hearing loss bilaterally after blowing his nose at an interval of 1 year. Although conservative management for the right ear and exploratory tympanotomy with sealing of the possible site of perilymphatic leakage in the left ear were performed, hearing outcome was poor in both ears. To our knowledge, this is the first case of bilateral pneumolabyrinth occurring as a result of nose blowing.

Postharvest skin sooty dapple and decay disease of pear fruit often originates at small stain symptoms that occurred during harvest and handling. Experiments were conducted to characterize the effect of timing of application of disease control materials, and to evaluate sequential postharvest applications of fungicides or fungicides and bio-control agents. Fungicides and bio-control agents were increasingly less effective when the period between harvest and application was prolonged. Thiabendazole (TBZ) applied to fruit without artificial wounding or inoculation effectively reduced skin sooty and decay disease when applied within 3 weeks or 6 weeks in 2 years of study. TBZ, Fludioxonil and pyrimethanil were effective in controlling skin sooty and decay disease at artificial wounds inoculated with Cladosporium tenuissimum up to 14 days after inoculation. Application of TBZ at harvest followed 3 weeks later by application of Fludioxonil was superior to application of TBZ at harvest alone. Two bacterial biocontrol agents reduced skin sooty and decay disease at pear wounds inoculated with C. tenuissimum up to 14 days after inoculation with C. tenuissimum, but were ineffective when applied at 28 days after inoculation. Of possible sequential arrangements of fungicide and bio-control treatments, application of the most effective material promptly after harvest generally resulted in the highest level of disease control.

This study was carried out to determine the causal agents of soil-borne fungal diseases that pose a threat to the muskmelon production in Cheong Yang, Korea and to investigate the potential effects of hot water drenching and three fumigant (metam sodium, dazomet and methyl bromide) on these diseases. As the agents of the diseases, Monosporascus cannonballus, Didymella sp., Fusarium sp., Phytophthora sp., were detected. Hot water and the fumigants were treated on two successive cropping seasons of melon. Soil temperature was measured at 0, 10, 20 and 30 cm soil depth. In 2005, soil sterilization by hot-water was more effective significantly to control of the diseases than by fumigant. yield was the highest in hot-water sterilized plot as 39 ton·ha−1. Dazomet (50 g/m2) treated plot was followed as 23 ton·ha−1. In 2006, hot water sterilized plot showed higher yields than non-treated plots (14.8 ton·ha−1). But the other three fumigant contained Dazomet (50 g/m2) were no difference (P<0.05) in yield.

Effect of Potassium Silicate Amendments in Hydroponic Nutrient Solution onthe Suppressing of Phytophthora Blight (Phytophthora capsici) in Pepper

이중섭,서상태,장한익,배도함,T.C Wang,L.M. Eagle 한국식물병리학회 2004 Plant Pathology Journal Vol.20 No.4

Amendments of a recirculating nutrient solution with potassium silicate were evaluated as a means to control Phytophthora capsici infections on pepper plant (Capsicum annuum L.). Supplying the solutions with 100 or 200 ppm of silicate significantly reduced motility, root decay, and yield losses attributed to infection of P. capsici. Treating inoculated plants with potassium silicate increased root dry weights and number of fruit, especially high-grade fruit. Results were slightly superior to non-inoculated controls. The two varieties, PBC 137 and PBC 602, responded similarly to the treatments. No significant differences were observed between the 100- and 200 ppm silicate treatments. Results were better when greenhouse conditions favored the spread of P. capsici. Silicon alone did not increase pepper yield, suggesting that it acts as a disease suppression agent rather than as a fertilizer. The phenomena by which silicon confers protection against P. capsici infection and disease development are not fully understood, but our results indicate that mechanisms other than a mechanical barrier to fungal penetration are involved.
