Abstract

This study was carried out to investigate the occurrence and distribution of ALS inhibiting herbicide-resistant weeds and to estimate the appeared areas of resistant weeds in the paddy fields of Gyeongnam province of Korea in 2017 and 2018 using a soil assay method. Compared with the 2012 survey, this study showed that the infested ratio of ALS inhibiting herbicide-resistant weeds increased from 1.0% to 66.8% and the infested area increased from 876 ha to 49,008 ha. The infested area of ALS inhibiting herbicide-resistant weeds was estimated in Ulsan-si (8.4%), Hapcheon-gun (8.3%), Haman-gun (7.9%), Goseong-gun (7.9%), Hadong-gun (7.3%), Jinju-si (7.2%), Changnyeong-gun (7.0%), Gimhae-si (6.4%), Miryang-si (5.5%), Busan-si (4.9%), Uiryeong-gun (4.6%), Namhae-gun (4.3%), Geochang-gun (4.2%), Changwon-si (3.8%), Geoje-si (2.9%), Yangsan-si (1.8%), Sancheong-gun (0.9%) and Tongyeong-si (0.4%), and the herbicide resistant weeds was not occurred in Hamyang-gun. The most dominant ALS inhibiting herbicide-resistant weeds in paddy fields were Monochoria vaginalis, followed by Echinochloa oryzicola, Lindernia dubia, Scirpus juncoides, Ludwigia prostrata, Cyperus difformis, Sagittaria trifolia and Rotala indica. ALS inhibiting herbicide-resistant M. vaginalis, L. dubia, and E. oryzoides occurred throughout Gyeongnam province, and ALS inhibiting herbicide-resistant S. trifolia and R. indica were only found in Gimhae-si. Therefore, these results will be utilized to estimate population dynamics of ALS inhibiting herbicide-resistant weeds and provide proper management practices in the paddy fields of Gyeongnam province.

본 연구는 2017과 2018년에 토양검정법을 이용하여 경남 지역의 논에서 ALS 저해 제초제 저항성 잡초의 발생과 분포를 조사하기 위해 수행하였다. 2012년도 제초제 저항성 잡초조사의 결과와 비교하여 볼 때 경남지역 각 시 군의 논에서 조사된 ALS 저해 제초제 저항성 발생율은 1.0%에서 66.8%로, 발생면적은 876 ha에서 49,008 ha로 크게 증가하였다. 경남지역의 ALS 저해 제초제 저항성 논잡초의 발생 면적은 울산시(8.4%), 합천군(8.3%), 함안군(7.9%), 고성군(7.9%), 하동군(7.3%), 진주시(7.2%), 창녕군(7.0%), 김해시(6.4%), 밀양시(5.5%), 부산시(4.9%), 의령군(4.6%), 남해군(4.3%), 고성군(4.2%), 창원시(3.8%), 거제시(2.9%), 양산시(1.8%), 산청군(0.9%) 및 통영시(0.4%)순이였고, 함양군에서는 제초제 저항성 잡초가 발생되지 않았다. 가장 우점한 제초제 저항성 잡초는 물달개비였으며, 그 다음으로 논피, 미국외풀, 올챙이고랭이, 여뀌바늘, 알방동사니, 벗풀 및 마디꽃 순으로 발생하였다. 제초제 저항성 물달개비는 경남지역의 대부분의 시 군에서 발생하였으나, 저항성 벗풀과 마디꽃은 김해시에서만 발생하였다. 따라서 이러한 정보는 ALS 저해 제초제 저항성 논잡초의 확산을 방지하고 효율적 관리 방안을 수립하는데 이용할 할 수 있을 것으로 판단된다.
