Incidence rates of bacterial canker, bacterial leaf spot and postharvest fruit rot on the Korean yellow-fleshed kiwifruit cv. Haegeum were compared with those on the most popular green-fleshed kiwifruit cv. Hayward grown in several naturally infected kiwifruit orchards in 2013 and 2014. The percentages of diseased leaves caused by bacterial canker were 18.5% and 17.3% on Hayward in 2013 and 2014, but those on Haegeum were 1.2% and 0%, respectively. The percentages of diseased leaves caused by bacterial leaf spot on Hayward were 63.5% and 16.2% in 2013 and 2014, respectively, but no bacterial leaf spots were observed on Haegeum in both years. The average percentages of diseased fruits caused by postharvest fruit rot were 24.2% and 20.5% on Hayward in 2013 and 2014, while 6.3% and 4.4% and Haegeum, respectively. Botryosphaeria dothidea was turned out to be the major pathogen of postharvest fruit rot on both cultivars.

Several fungicides such as polyoxine B, fludioxonil, tebuconazole, tebuconazole+dichlofluanid, and fenbuconazole were sprayed once a week on roses in greenhouse. Botrytis infection on stalks was reduced by 71-89% after regular fungicide spray. The reduction of conidial inoculum by these treatments is also observed. The rose petal infections were controlled significantly by these fungicides only 2 days after the application. The development of gray mold on rose flowers harvested just after spray of fludioxonil, tebuconazole and tebuconazole+dichlofluanid were reduced compared to untreated control. This beneficial effect was also shown in flowers artificially inoculated with B. cinerea conidia after harvest. Post-harvest treatments by spraying cut flowers with the fungicides such as iprodine plus thiram, tebuconazole+dichlofluanid and polyoxin D reduced disease incidence by 50-55%.

This studies were investigated the occurrence of sclerotinia rot at the crisphead lettuce field in Uiryeong-Gun, Gyeongsangnam-Do from January to May in 2003. Average incidence rates of sclerotinia rot on crisphead lettuce was up to 21.9% at the five plastic houses. A total of 140 isolates of Sclerotinia sp. were obtained from diseased leaves of crisphead lettuce. Among them, the fungi YR-1 was isolated, which showed highly virulent on the whole plant. the YR-1 was identified as Sclerotinia sclerotiorum based on the formation, color, shape and size of sclerotium and apothecium. For the pathogenicity test, the most suitable inoculum quantity of YR-1 strain was selected as the triturated mycelial suspension of $A_{550}$=0.8, 40 ml showing disease incidence of 94%, and the symptom showed as same as at the fields, the leaves and stem had rotten and developed white downy mycelial at the diseased lesion on the leaves and stems, and produced black and irregular sclerotinia. This is the first report on the pathogenicity test using by triturated mycelial suspension-inoculum of the pathogen for the sclerotinia rot of crisphead lettuce.

This study was investigated the occurrence of sclerotinia rot caused by Sclerotinia sclerotiorum at the major perilla cultivating area, Gangdong-dong, Gangseo-gu, Busan in 1998. The incidence of this disease ranged from 8.1 to 28.3% at Gangdong-dong area during the growing seasons. Symptoms of the disease initially appeared damping-off of infected stems and soft-rot on the leaves of perilla. Under the relatively high humidity, abundant white mycelia of the pathogen formed on the lesion developed into black sclerotia later and the infected leaves were finally fell down. Sixteen isolates, Sl-S16, isolated from diseased lesions showing typical symptoms, and pathogenicity was tested using mycerlial disks. Among them, S2 isolate showing the most strong pathogenicity was selected and identified as Sclerotinia sclerotiorum on the basis of morphological and cultural characteristics. For biological control, an antagonistic bacteria, N4 isolate which effectively inhibited not only mycelial growth of S2 isolate but also suppress sclerotinia rot on the pot assay, was selected and identified as Bacillus megaterium according to Bergey's manual and API system., Wettable powder type, N4 formulation using B. megaterium N4 isolate was developed and estimated its control effect on perilla crops in a plastic house. As a results, N4 formulation which applied before 3 days inoculation of pathogen was effectually controlled Sclerotinia rot as the control value of 98.0%, was more effective than chemical fungicide, benomyl showing the control value of 78.0%. This is the first report of wettable powder formulation as a biocontrol agent using B. megaterium N4 against Sclerotinia rot caused by S. sclerotiorum on perilla.

가금에서 콕시듐병은 사육밀도에 따라 지나간 흔적이 정도에서 차이가 난다. 즉 가볍게 감염되면 자연면역이 생겨서 별 걱정없이 자랄 수 있는 이로운 점이 있으나 농오염(濃汚染) 즉, 바닥에 콕시듐 충란이 많거나 맹장콕시듐같은 측정 원인체가 감염되면 면역이 생기기 전에 발병(출혈)하여 사료효율과 육성율에 막대한 장해를 준다. 그러므로 최근에 이용되는 방법인 우수한 약제와 오염기회를 줄이는 합작 방역이 가장 이상적인 대책임을 기술하고자 한다.

흔히들 백내장은 노화로 인해 자연스럽게 발생하는 질환으로 알려져 있다. 허나 최근 들어 비교적 젊은 나이에 백내장을 호소하는 환자들이 늘어나고 있는데, 그 발생요인으로 당뇨병도 한 부분을 차지하고 있다. 당뇨병이 있으면 일반인에 비해 백내장에 걸릴 확률이 7배 이상 높아지고, 나아가 발병하는 연령 또한 낮아진다. 치료하지 않고 방치한다면 시력저하는 물론 실명에 까지 이를 수 있는 백내장. 백내장이 무엇인지 알아보고 치료와 예방법에 대해 알아보자.

Fusarium wilt caused by Fusarium oxysporum f. sp. cucumerinum has caused high damage in cucumber under greenhouse condition. This disease was suppressed $30\~55\%$ by application of organic matters compared with natural cropping soils. The suppression effect was the highest in the mushroom humic compost and fowl excretion matter among the various organic matters, varying with kinds of organic matters and degrees of humic resolvability. There was a slight difference in severity of fusarium wilt between sterilized organic matters and soils. The disease occurrence was delayed more in the nonsterilized organic matters and soils than in the sterilized ones. At 30 days after inoculation of F. oxysporum, numbers of Actinomycetes, fungi and bacteria were considerably increased, whereas F. oxysporum was decreased in the organic matter amended-soils compared with natural control soils.
