Since 1970, herbicides have been widely used in the crop production, especially in paddy field in Korea. In 1978, both preemergence and postemergence type herbicides are applied in the approximately 70% of total paddy field and 15% of upland to control weeds. Most herbicides control annual weeds effectively, but perennials have been problems in the paddy field. Under upland conditions, effectiveness of herbicides varies depending on many environmental conditions (soil moisture, soil physical properties, temperature, etc.) as well as uniform application of appropriate amounts of herbicides. In Korea, many research works have been concentrated on the screening of new herbicides in terms of herbicide effectiveness and yield or phytotoxicity of crops, and especially on the paddy field. However, physiological aspects of herbicidal action in plant and interaction of herbicides with the environments have not been studied approximately. Therefore, researches on the uptake of herbicides and the influence of herbicides on the physiological phenomena such as photosynthesis, respiration, nutrient uptake etc., to control troublesome perennial weeds in the paddy field are needed in future. Also some researches are needed to improve effectiveness of herbicirdes under upland conditions.

In recent years weed flora have been changed to perennial dominance in paddy field being affected by the cropping systems and cultural practices. The perennial weeds are difficult to be controlled with annual herbicides which occupy 94% of total consumption of herbicides. The weeds competed more with rice plants in early tillering stages in machine transplanted field. For the reasonable and effective weed control, it is advisable to use single ai herbicides in hand transplanting field, but combined and mixed herbicides should be applied in machine transplanting field.

This study was carried out to investigate the classification and the growing charicteristics of weed species in a newly formed lawngrass land. The results obtained are summarized as follows: 1)Weed population in a newly formed lawn field consisted of 30% of Gramineae, 15% of Compositae, and 12% of Leguminosae family. 2)Percentage of weed emergence between April and May was 39.4%. The same amount of weed emergence was observed at the period of September and October, where as the percentage was 21.2% at the period of March and April. 3)The population ratio of flowering date of weed species was in order of 48.5% July and August, 30.3% in May and July, 12.1% in March and April, and 9.1% in September and October. 4)Weed classification by life cycle showed 39.4% of biennials, 33.3% of annuals, and 27.3% of perennials. 5)Weed species were grouped according to the plant height. The ratios of each group were 33.3% of 20~40cm group, 27.3% of 40~60cm group, 24.2% of shorter than 20cm group, and 15.2% of taller than 60cm group.

도시하천 제방사면의 다년생 초본류 군락 형성 연구를 위해 2009년 4월 중순 물억새, 억새, 띠, 수크령, 새를 식재하였다. 새는 분주를 식재하였고, 나머지 초종은 이년생 포트를 식재하였다. 식재 후 3년간 매년 2회의 잡초 제거를 통해 2011년 군락이 형성되었다. 2012년과 2013년은 잡초를 제거하지 않고 실험초종이 군락을 유지하는지 관찰하였다. 잡초를 제거한 2011년과 잡초를 제거하지 않은 2012년간, 잡초를 제거하지 않은 2012년과 2013년간 줄기수와 초장에 차이가 있는지 5월, 7월 9월의 줄기수와 초장을 활용하여 유의수준 0.05에서 t-검정을 하였다. 실험초종 모두 2012년의 줄기수가 2011년보다 적어(p<0.001) 잡초의 피해를 입었다. 억새, 띠, 수크령, 새의 초장은 2012년이 2011년보다 작아 잡초의 피해가 나타났다. 물억새의 초장은 5월과 7월에 차이를 보여 잡초의 피해를 입었으나 (p<0.001), 9월에는 차이가 없어(p=0.098) 피해를 입지 않았다. 2012년과 2013년간t-검정 결과, 새를 제외한 나머지 초종은 줄기수와 초장에 차이가 없었다(p>0.05). 이들 초종은 군락이 형성된 후 잡초의 피해 없이 군락이 유지되었다. 새는 줄기수와 초장 모두 차이를 보여 잡초의 피해가 컸다. 물억새, 억새, 띠, 수크령은 군락 형성 후 잡초 제거 없이 군락이 유지되었으나, 새는 잡초의 피해가 커 군락 유지가 어려웠다. 군락 형성 및 유지, 하천경관 개선, 제방사면 보호의 관점에서 물억새, 억새, 띠가 적합한 것으로 나타났다.

본 연구는 전라남도 장성지역의 한국잔디 재배지의 발생 잡초를 확인하기 위하여 2014년 9월(1차 조사)과 2016년 5월(2차 조사)에 전남 장성군 삼서면 일대에서 한국잔디 재배포장을 밭 토양과 논 토양으로 구분하여 발생잡초 분포조사를 수행하였다. 잡초분포 조사결과 밭 토양에서는 27과 66종(일년생 49종, 다년생 17종)으로 일년생잡초 74.2%, 다년생잡초 25.8%의 발생을 확인하였다. 과별로 보면 국화과(Compositae)가 19.7%로 가장 많이 발생하였고, 그 다음으로 벼과(Gramineae) 13.6%, 콩과(Leguminosae) 10.6% 순이었다. 논 토양에서는 22과 69종(일년생 53종, 다년생 16종)으로 일년생잡초 76.8%, 다년생잡초 23.2% 비율의 발생을 확인하였다. 과별로 보면 국화과(Compositae)가 18.8%로 가장 많이 발생하였고, 그 다음으로 벼과(Gramineae) 14.5%, 사초과(Cyperaceae) 7.2% 순이었다. 밭 토양의 1차 조사에서는 벼과의 바랭이(8.49), 2차 조사에서는 괭이밥과의 괭이밥(7.26)이 가장 우점하였고, 논 토양의 1차 조사에서 국화과의 개망초(9.52), 2차 조사에서는 닭의장풀과의 닭의장풀(5.08)과 벼과의 뚝새풀(5.08)이 가장 우점하는 잡초종으로 확인되었다. 잡초발생 현황을 조사시기와 토양조건을 구분하여 비교한 결과 논 잡초와 밭 잡초가 혼생하는 것으로 확인되었다. 조사시기 또는 토양조건에 상관없이 공통적으로 발생하는 초종의 비율이 49.2%로 비교적 높게 나타났다. 따라서 한국잔디 재배지에서 제초제를 이용한 효율적인 방제효과를 위해서는 재배토양에 상관없이 논 잡초와 밭 잡초를 모두 잘 방제할 수 있는 약제를 선택해야 할 것으로 판단되었다.

This study was carried out for management of the invasive alien plants in Mt. Inwang located in central Seoul. The invasive alien plants are 11 families, 34 genera, 30 taxa, and they are 10.8% of the total vascular plants(314 taxa). The ecosystem disturbed plants designated by the Korea environment ministry are 6 taxa : Rumex acetosella, Lactuca scariola, Ambrosia trifida var. trifida, Ambrosia artemisiifolia, Aster pilosus and Eupatorium rugosum. In the life-form, herbaceous perennials are 13 taxa(35.3%). In the continent of origin, the species from America are 20 taxa(58.8%). In the introduction time, the species of third period are 14 taxa(41.2%). In the diffusion grade, 5 grade species are 14 taxa(41.2%) and they are wide spread species. Mt. Inwang was designated as ecological scenery conservation area of Seoul in 2007. But Mt. Inwang is in high danger by the spread of invasive alien plants and ecosystem disturbed plants, due to artificial factors such as development pressure and the occurrence of byway trail. Therefore, Mt. Inwang needs systematic management of invasive alien plants and monitoring of long-term changes.

This study was conducted in order to utilize the basic data for weed control by surveying the occurrence of weed species. Total 63 sites of upland Chinese cabbage fields in Chungnam Provinces were investigated. The result of survey, 71 weed species in 25 families were identified and classified to 39 annuals, 16 biennials and 16 perennials. Based on the occurrence ratio, the most weed species belonged to Compositae (20 species). 8, 6 and 5 weed species belonged to Poaceae, Cruciferae and Polygonaceae, respectively, and these 10 weed species in the most six families accounted for 50% of total weed occurrence. The most dominant weed species in upland Chinese cabbage fields were Portulaca oleracea (8.07%), followed by Digitaria ciliaris (7.54%), Rorippa palustris (6.44%), Chenopodium album (5.73%), Echinochloa crus-galli (5.02%) and Cyperus amuricus (3.95).
