In July 2019, damping-off symptoms of young Fischer's ragwort (Ligularia fischeri) plants were observed in four vinyl greenhouses of a farmer located in Taebaek, Gangwon Province, Korea. This disease occurred in 20-30% of plants in the vinyl greenhouses investigated. Nine isolates of Rhizoctonia sp. were obtained from the diseased plants. All the isolates were identified as Rhizoctonia solani AG-2-2 (IIIB), based on morphological, cultural characteristics, and anastomosis test. Three isolates were used for artificial inoculation test on Fischer's ragwort. Pathogenicity of these isolates was confirmed on the plants with the inoculation tests. Damping-off symptoms observed on the inoculated plants were similar to those observed in the diseased plants in the vinyl greenhouses. This is the first report of R. solani AG-2-2 (IIIB) being the causative agent in damping-off in Fischer's ragwort.

This study was performed on 302 cases of leptospirosis, tsutsugamushi disease and hemorrhagic fever with renal syndrome(HFRS) which occurred in Chonnam(Do) in 1991 through 1993. The results were as follows : 1. 81.8% of the patients with Leptospirosis and 54.5% of the HFRS patients were men while 61.4% of the patients with tsutsugamushi disease were women. 2. Most patients lived in rural areas(Gun), their educational level was elementary School or lower and their occupations were either farmer or jobless. 3. Peak ages were 40s for leptospirosis(36.4%) and 50s for tsutsugamushi disease and HFRS(32.9% and 36.4% respectively). 4. The high incidence areas of tsutsugamushi disease were northern, eastern and a diagonal line, from northeast to southwest, of the Chonnam area, and these are consistent with a mountainous district. 5. In monthly distribution leptospirosis was higher in Sep. and Oct., and tsutsugamushi disease and HFRS were higher in Oct. and Nov. 6. The first case is occurring and the last case shows up later than in past years.

Plant diseases are a significant yield and quality constraint for farmers around the world due to their severe impact on agricultural productivity. Such losses can have a substantial impact on the economy which causes a reduction in farmer's income and higher prices for consumers. Further, it may also result in a severe shortage of food ensuing violent hunger and starvation, especially, in less-developed countries where access to disease prevention methods is limited. This research presents an investigation of Directional Local Quinary Patterns (DLQP) as a feature descriptor for plants leaf disease detection and Support Vector Machine (SVM) as a classifier. The DLQP as a feature descriptor is specifically the first time being used for disease detection in horticulture. DLQP provides directional edge information attending the reference pixel with its neighboring pixel value by involving computation of their grey-level difference based on quinary value (-2, -1, 0, 1, 2) in 0°, 45°, 90°, and 135° directions of selected window of plant leaf image. To assess the robustness of DLQP as a texture descriptor we used a research-oriented Plant Village dataset of Tomato plant (3,900 leaf images) comprising of 6 diseased classes, Potato plant (1,526 leaf images) and Apple plant (2,600 leaf images) comprising of 3 diseased classes. The accuracies of 95.6%, 96.2% and 97.8% for the above-mentioned crops, respectively, were achieved which are higher in comparison with classification on the same dataset using other standard feature descriptors like Local Binary Pattern (LBP) and Local Ternary Patterns (LTP). Further, the effectiveness of the proposed method is proven by comparing it with existing algorithms for plant disease phenotyping.

시설재배 되는 들깨에 발생하여 피해를 초래하는 균핵병 발생 특성에 대하여 조사연구한 결과, 들깨 균핵병균(S. sclerotiorum)의 균사생장 적온은 $20^{\circ}C$이었고, $15^{\circ}C$ 이하의 온도에서 $20^{\circ}C$ 이상의 온도에서보다 균핵의 형성수는 적었으나 보다 큰 균핵을 형성하였으며 건물중도 높았다. 토양 깊이별 균핵의 자낭반 형성은 0.5 cm에서 가장 높았고 3cm 깊이까지 자낭반을 하였으나 5cm 이상의 깊이에서는 자낭반 형성이 관찰되지 않았다. 들깨 균핵병은 전 생육기에 걸쳐 발생하였고, 특히 저온 다습기인 1월에서 2월에 발생이 높았다. 그리고 5년 이상 연작 재배시 높은 발병을 보였으며, 10년 이상 연작재배 포장은 20% 이상의 발병을 보여 많은 피해를 초래하였다. 또한 들깨 시설재배 농가 포장에서 자연 감염에 의한 균핵병이 떡쑥, 주름잎 등의 잡초에 발생하였으며, 병원성 조사결과, 화본과를 제외한 국화과 등 6개과에 속하는 11종의 잡초에 병원성을 나타내었다. 이런 결과는 윤작과 효율적인 잡초관리가 들깨 균핵병 발생을 경감할 수 있고, 벼 후작으로 시설재배 되는 들깨에 균핵병이 격발하는 원인을 설명할 수 있는 하나의 자료가 될 수 있을 것으로 생각된다.
