This study was conducted to provide basic information for weed control by surveying the occurrence of weed species. Surveys of weed species occurred in food crop (barley, maize, potato, soybean) fields were conducted in Chungnam province from April to September in 2014. Total 321 sites of food crop fields in 17 City / Gun in Chungnam province were investigated. From the result of this survey, 130 weed species in 36 families were identified and classified to 77 annuals, 27 biennials and 26 perennials. Based on the occurrence ratio, the most dominant weed species in Chungnam province food crop fields were Digitaria ciliaris (10.19%), followed by Conyza canadensis (7.82%), Portulaca oleracea (5.22%), Chenopodium album var. centrorubrum (5.21%), Capsella bursa-pastoris (3.47%) and Alopecurus aequalis (3.47%). Forty-four exotic weed species were identified. This information could be useful for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods in food crop fields of Chungnam province.

본 연구는 2014년 5월부터 9월까지 대전광역시와 세종특별자치시를 포함하는 충청남도 17개 시 군에 속하는 식량작물(보리, 옥수수, 감자, 콩)재배포장에서 발생하는 잡초분포 현황을 알아보았다. 조사결과, 충남지역 주요 식량작물 재배지에서 발생하는 잡초는 총 36과 130종으로 일년생잡초가 전체의 59%를 차지하는 77종, 월년생잡초가 21%로 27종, 그리고 다년생잡초가 20%로 26종이었다. 바랭이가 중요치 10.19%로 가장 많이 발생하였으며 망초(7.82%), 쇠비름(5.22%), 명아주(5.21%) 순으로 우점하였다. 환경부지정 악성 위해잡초로 분류된 서양금혼초와 가시상추를 포함한 외래잡초 44종의 발생을 확인하였다. 이번 연구결과를 바탕으로 앞으로 식량작물재배지에 발생하는 잡초양상 예측 및 잡초군락 변화 파악으로 체계적인 잡초관리방안 마련의 기초자료 확립에 활용 가능할 것으로 판단된다.
