The present invention relates to a liquid herbicidal composition, and more particularly, to a liquid herbicidal composition which includes an active ingredient and a buffer, wherein the active ingredient may comprise a pyridine sulfonylurea compound represented by Formula 1, and the buffer may have a pH of 5.80 to 6.25. The liquid herbicidal composition has excellent herbicidal activity, is improved in stability even when being prepared in liquid formulations, particularly, suspension concentrate formulations, and thus easily stored for a long time.本發明關於液體除草組成物，且特別關於包括活性成分及緩衝劑之液體除草組成物，其中該活性成分可包含以式1代表的吡啶磺醯脲化合物，且該緩衝劑可具有5.80至6.25之pH。該液體除草組成物具有極佳的除草活性，改進了穩定性，即使在製備成液體調配物、特別為懸浮液濃縮調配物時亦然，且因此易於長時間貯存。
