잡초생태학에 대한 지식이 잡초방제법 확립의 기초가 되고 있음은 두말할 나위가 없다. 잡초의 생존과 번무에 대한 특성을 명확하게 알지 못하고서 효율적인 잡초의 방제 및 관리를 기대하기는 어렵다. 잡초의 전반적인 특성, 이른바 잡초생물학을 자세히 파악함으로써 이를 기초로 한 유효한 방제법의 수립이 가능하고, 그 결과 작물에 대한 잡초의 피해를 최소한으로 줄일 수 있다.

비농경지는 농산물과 임산물을 생산하는 농경지,임야등을 제외한 모든 공지를 의미하지만 잡초방제를 대상으로 보면, 택지, 공업용지와 도로, 고속도로, 철도, 학교 운동장, 공원 등이 포함되는 공공용지로 구분할 수 있다. 농경지는 국가경제가 발전될수록 계속 잠식되어 택지, 공장부지 및 공공용지로 이용됨에 따라 비농경지 면적은 점차 확대되고 있으며 따라서 비농경지에 발생된 잡초방제의 필요성은 더욱 증대되리라 예상된다. 그러나 아직 우리나라에서는 체계적으로 비농경지 잡초의 분포, 방제법 등에 관한 연구가 거의 이루어지지 않고 있으며 잡초방제의 중요성과 관심도 매우 적은 실정이다. 따라서 비농경지에서 발생되는 잡초의 종류 및 피해양상, 잡초방제의 특성과 제초제를 이용한 잡초방제법을 정리하여 보기로 한다.

The survey of weed occurrence was conducted to identify problem weed species in the paddy field. The 320 sites of the 13 regions in Gyeongbuk Province were investigated from June to July, 2013. In the whole region, 51 weed species were identified including 34 annuals and 17 perennials. The highest importance value of annual weed and perennial was dominant 88.4 and 48.7%, in Gumi region, respectively. The most dominant weed species in paddy fields of Gyeongbuk Province were Monochoria vaginalis var. plantaginea (10.80%), followed by Lemna paucicostata (10.74%), Bidens tripartite (8.77%), Echinochloa oryzoides (7.17%), and Scirpus juncoides (6.20%). The similarity of paddy weeds in 13 regions observed through TWINSPAN analysis was distinguished by Ludwigia prostrata, Scirpus juncoides, Lindernia dubia, Polygonum aviculare, and Alopecurus aequalis var. amurensis. The weed species, Ludwigia prostrata, was divided into the four regions, Gyeongju, Gumi(direct seeding cultivation), Youngcheon and Euiseong and ten regions, Gumi, Bonghwa, Sanju, Goryung, Youngdeog, Pohang, Sanju, Andong, Yecheon, and Cheongdo.

농사는 잡초와의 싸움이라고 하였다. 벼농사에서 파종, 육묘, 이앙 등의 재배과정은 기계화로 인해 투입 시간이 매년 절감되고 있으나 잡초 방제 투입 시간은 증가하고 있을 뿐만 아니라 제초제 사용 횟수도 증가하고 있다. 이러한 원인의 가장 큰 이유는 논에서 제초제 저항성 잡초들이 전국적으로 빠르게 확산하고 있기 때문이다. 제초제 저항성 잡초의 발생 원인과 잡초 제거 방법에 대해 알아본다.

This paper reviews current status of weed science in Asian-Pacific regional agricultural systems based on the 24th Asian-Pacific Weed Science Society Conference. About 190 researchers from 16 countries including Korea participated in the Conference and presented 160 papers in 11 research areas. Major research topics were invasive weeds and their ecology, allelopathy, weed management in paddy field, weed management in field crops, and herbicide resistance. Because rice is a major food crop in Asian countries, weed control and herbicide resistance management in paddy field were a main object of research. Weed control in maize, soybean and wheat has also been studied continuously. To prevent the increase of problematic weeds and to overcome food crisis, the importance of weed-related researches has been raised. Therefore it is expected that various weed management systems and control of herbicide resistant weeds should be studied continuously in the future.

The weed flora in the Codonopsis lanceolata upland fields were surveyed in Hoengseong and Jeju in May, August, and October of 2014. The objectives of this study were to use the survey data for establishing weed control methods and to bring awareness of possible problematic weeds occurred in C. lanceolata upland fields in Korea. Altogether 207 weed species of 47 families were identified, of which 87 were annual, 47 species were biennial and 73 were perennial. Based on the morphological characteristic of the leaves, 182 species were broad leaves, 18 species were grasses, and 7 species were sedges. The dominance was highest in the Artemisia princeps followed by Digitaria ciliaris, Commelina communis, Persicaria longiseta and Echinochloa crus-galli etc. Fifty-nine species were exotic weeds with 29% of a total presence, of which Erigeron annuus was highest, followed by Crassocephalum crepidioides, Bidens frondosa, Hypochaeris radicata etc. In the PCA plot, weeds presented in the C. lanceolata upland fields of Hoengseong were divided into three groups, E. annuus, Sigesbeckia pubescence and C. communis communities and those of Jeju were divided into four groups, C. crepidioides-Cyperus iria, Spergula arvensis, Poa annua and Youngia japonica communities.

This paper provides the current status of weed science and prospects for the development of weed science based on the research trends presented at the 7th International Weed Science Conference in 2016. Approximately 520 researchers from 59 countries, including Korea, participated in the conference and presented 625 papers in nine research areas. Major research topics were herbicide resistance, weed ecology, weed management in agricultural and non-agricultural lands, herbicide spray technology, and non-chemical weed control. Studies on herbicide resistance presented more than 30% of all papers presented. Particularly, resistance to non-selective herbicides, such as glyphosate and glufosinate-ammonium, and non-target sites of resistance mechanisms were the main subjects of the herbicide resistance research area. Moreover, the conference focused on research concerning herbicide resistant weeds of staple crops of the world (corn, wheat, and rice). Arylex was introduced as a new compound which has a mode of herbicidal action similar to synthetic auxin. Three compounds being developed as HPPD inhibitors were studied for ways to reduce their toxicity and tested as mixed with safeners. Additionally, parasitic weeds, which are not native to Korea, are an expanding research subject in the world. Although 45 years have passed since the first report of herbicide resistance in 1970, herbicide resistance remains a serious problem in most intensive cropping systems of the world and will continue to be a major area of study in the future.

고추는 여름철에 왕성하게 생육하는 여름잡초들과 빛 양분, 수분을 두고 경합하게 된다. 따라서 이들 잡초들을 관리하지 못하면 고추의 많은 수량 감소가 발생한다. 고추밭에 주로 발생하는 잡초는 바랭이, 쇠비름, 방동사니, 깨풀, 돌피, 명아주 등이 있으나, 이들 외에도 가끔 발생하는 쑥, 메꽃 등의 다년생 잡초와 자생능력이 큰 실새삼 등은 초기에 적극적으로 방제하지 않으면 대 발생할 수 있으므로 주의가 필요하다.

Investigation on weed flora in Angelica gigas upland fields was conducted to understand the current status of the weed flora and establish the control measures. Investigation was conducted twice, July and October in 2015. From this investigation, 105 species of 37 families including 27 exotics were identified and classified into 53 species of annuals, 24 species of biennials and 28 species of perennials. Dominance was the highest with Digitaria ciliaris, followed by Portulaca loeracea, Chenopodium album, Cyperus iria, Conyza canadensis, Galinsoga ciliata etc. in order. Chenopodium album was the highest in importance analysis and the followings were in order of Conyza canadensis, Galinsoga ciliata, Amaranthus lividus, Taraxacum offcinale etc. The yield of A. gigas was reduced 49.6% in no weeding plots comparing in weed managed plots.
