Occurrence of ripe rot in Vitis vinifera cv, Campbell Early was examined at Daegu, Yaungchon, and Kimchon in Kyungbuk province, Korea from 1997 through 1999. Its occurrence was related to rainfall days in July and Auguest. In cv, Campbell Early, the disease started in late July, and increased rapidly from mid August. Considering the incubation time, the pathogen infection might have increased from late July, which was confirmed by wrapping grape clusters in field and in vitro tests. By scanning electron microscopy, it took 24 h or longer for infection to occur in moisturized conditions. Chlrorothalonyl WP (500$\times$) sufficiently reduced ripe rot disease when the chemical was sprayed 3 or 4 times during the growing season.

버즘나무(Platanus occidentalis)는 북미가 원산으로 우리나라의 경우 가로수와 공원수로 많이 식재되어 있으며, 빨리 자라고 쉽게 증식되어 양질의 펄프와 상업용 베니아판을 만드는데 좋은 목재로 쓰이고 있다. 그러나 가로수 버즘나무의 경우 가장 흔하면서도 잘 보이지 않는 병들 중 하나가 바로 탄저병인데, 탄저병은 잎이 처음 나올 때 서늘하고 습한 봄 날씨가 계속되면 병이 심해지고 서양물푸레나무, 참나무, 단풍나무 등이 쉽게 감염된다. 미국의 경우 1952년 일리노이주 전역에서 대발생하였으며, 1970년에는 미시시피주에서 버즘나무 잎이 75%가 떨어지고 약 33%이상이 감염되었다. 우리나라에서는 1987년 남부지역에서 탄저병이 발생한 후 5년 만에 전국적으로 크게 발생하여 많은 피해를 입혔으며 중부지역 $50.6{\sim}72.4%$에 이르는 높은 발병율을 나타내었다.

One of the most important vegetables consumed in Korea, chili peppers (Capsicum annuum) are widely cultivated around the world. Chili peppers have been severely damaged by anthracnose during their growth, so it is important to study prevention and resistance varieties. K1 anthracnose was inoculated against four cultivar of chili peppers that are resistant to anthracnose and one cultivar that is sensitive. The area of the disease that appeared over time was photographed and quantified through the program was analyzed. Through the ratio of the area of chili pepper fruit and the area of the bottle, the sensitive variety An-S showed weak reactions to anthracnose with about 40%, the resistant variety An-12R (23%), An-Tan (21%), and An-9R (19%), and PBC81 showed a strong response to anthracnose with about 11%. These quantitative value can be used as a basis for comparison in conducting resistance studies for new varieties.

고추에 피해를 주고 있는 병으로 잎오갈병, 더뎅이병, 탄저병, 역병등 19종이 우리나라에 보고 되어 있다. 이러한 고추의 병해를 병원균별로 보면 담배모자이크바이러스등 바이러스가 5종, 더뎅이병균등 세균이 3종이 있으며 곰팡이는 역병균등 14종이 고추에 병을 일으키고 있다. 이와같은 고추병들이 고추에 피해를 주고 있지만 그중에서도 특히 고추를 이어짓기 하는 밭이나 비닐하우스에서 고추의 작황을 좌우하는 것은 대부분이 역병에 의한 피해이다. 역병의 피해는 물론 고추를 이어짓기함으로써 토양 전염되는 역병균의 전염원이 매년 증가하기 때문이기도 하지만 역병이 발생하기 쉬운 여름철에 장마가 겹치므로 물빠짐이 나빠지거나 침수가 되기 때문에 피해가 증가하는 요인이 되고 있다.

An anthracnose on potato leaves was observed in Kangwon alpine and Kangnung areas in Korea. A fungal pathogen was repeatedly isolated from the leaf lesions and stems of the infected plants and identified as Colletotrichum coccodes. The fungus showed pathogenicity on the leaves of potato inoculated. This is the first report that anthracnose of potato caused by Colletotrichum coccodes was occurred in Korea.

Cucumber (Cucumis sativus L.) is substantial economic importance in South Korea, with its cultivation occupying a significant portion of agricultural land. However, sustainable cucumber production requires effective management of various diseases affecting the crop yield. In this study, we explored the potential of Streptomyces sp. S20-465-derived metabolites in controlling cucumber anthracnose disease caused by Colletotrichum orbiculare. This study identified 4-hydroxy-4-methyl-2-pentanone as a potent antifungal compound present in the n-hexane extract of Streptomyces sp. S20-465 culture filtrate. This compound exhibited significant the disease reduction, demonstrating their potential as control agents. Our findings suggest that Streptomyces sp. S20-465-derived metabolite could serve as an effective tool for managing cucumber anthracnose, offering a sustainable approach to enhancing cucumber production. Further research into the application and efficacy of these compounds in agricultural system will be conducted.

Occurrence of anthracnose on red pepper fruit was examined at 6 red pepper-growing regions including Yecheon, Andong, Euisong, Cheongsong, and Ponghwa in Kyungbuk province, Korea in 1999. The disease occurred firstly June 13 at Cheongsong, progressed gradually thereafteri and increased rapidly from late August. The average disease incidence with mid September was 30.4%. There was no significant difference in disease incidence among the regions examined. Correlation coefficient analysis of the disease incidence with weather factors revealed that it was significantly related to relative humidity, precipitation, rainy days, and duration of continuous rainy days. Most fungal isolates from the diseased fruit were Colletotichum gloeosporioides. In the in field experiment, unmature fruit was somewhat more susceptible to the disease than mature fruit. In the field experiment, the disease occurred severely in open fields, having the disease incidence of 12.1%; however, no disease was observed in the rain-proof fields. The anthracnose on red pepper fruit developed earlier and more severely in the successive cropping field with red pepper than the field having other crops. Removal of infected plant debris also delayed and reduced the disease occurrence, suggesting that plant debris infested with the anthracnose fungus serve as a primary inoculum source which may govern the severity of the disease in the field.

Anthracnose crown rot (ACR), caused by Colletotrichum fructicola, is a serious disease of strawberry in Korea. The primary inoculums of ACR were symptomless strawberry plants, plant debris, and other host plants. To effectively control anthracnose in symptomless transplanted strawberries, it is necessary to use disease-free plants, detect the disease early, and apply a fungicide. Therefore, in 2010 and 2011, we evaluated the efficacy of pre-plant fungicide dips by using strawberry transplants infected by C. fructicola for the control of anthracnose. Dipping plants in prochloraz-Mn for 10 min before planting was most effective for controlling anthracnose in symptomless strawberry plants and resulted in more than 76% control efficacy. Azoxystrobin showed a control efficacy of over 40%, but plants treated with pyraclostrobin, mancozeb and iminoctadine tris showed high disease severity. The control efficacy of the dip treatment with prochloraz-Mn did not differ with temperature and time. Treatment with prochloraz-Mn for more than an hour caused growth suppression in strawberry plants. Therefore, the development of anthracnose can be effectively reduced by dipping strawberry plants for 10 min in prochloraz-Mn before planting.

Field trials were conducted in Suwon, Andong, Bongwha and Taean to evaluate an anthracnose forecaster in the integrated pest management system (IPM) including anthracnose, Phytophthora blight and tobacco budworm for hot pepper in 2008-2009. Percentage of diseased fruits by pepper anthracnose and yield were compared among three treatments, no-fungicide, forecaster and conventional. The incidence and yield of the forecaster at Bongwha on two varieties were 3.1-3.5% and 30-33 kg/40 plants. These were little less than those of the conventional's 0.3-0.8% and 35-36 kg/40 plants and much higher than those of the no-fungicide's 23-27% and 18-24 kg/40 plants. The number of spray at the forecaster was 5 times, whereas those at the conventional was 11-19 times depending on the farmers. In addition, the results of an anthracnose forecaster at the other three field trials allowed in protecting hot pepper from anthracnose while reducing the amount of pesticides used and the total cost of the pathogen control. However, it is needed to improve for anthracnose forecaster when anthracnose pressure was high such as Taean where 60-80% of the incidence. Because the control values of the forecaster at Taean were between those of no-pesticide and conventional treatment at best. If anthracnose is severe early in the season, additional preventive control should be considered when the fruits were fully grown yet.

The incidence of Anthracnose causing severe damage to the foliage and fruit in watermelon has increased in some major watermelon producing areas in Korea. To develop anthracnose resistant line, 'AU-Producer' having resistant gene to anthracnose was selected from germplasm and crossed with high quality line '920533'. Following the initial cross, backrossing and disease screening were performed to select resistant lines that produced high yields with excellent quality fruit. As a results of these procedure, a mid maturing watermelon line, 'Hangyeol' with resistance to anthracnose (Colletotrichum orbiculare) race 1 and 3 was developed at the National Institute of Horticultural and Herbal Science, Rural Development Administration (RDA). It has red flesh and commonly produces fruit with clear stripes on skin between 5.3 to 10.1 kg. Average soluble solid contents are ranged from 9.8 to 11.8$^{\circ}$Bx. The yield and quality of 'Hangyeol' is comparable to or better than those harvested from the popular commercial cultivars. The achievement of this experiment could contribute to provide the resistant parents in an anthracnose resistance breeding program in watermelon.
