  A pyridone derivative represented by the general formula: wherein R is an alkyl group or a haloalkyl group, R1 is a hydrogen atom, an alkyl group, a haloalkyl group, an acetyl group, an amino group, an alkoxycarbonylamino group, an alkylcarbonylamino group or the like, R2 is a hydrogen atom, an alkyl group, a carboxyl group or an alkoxycarbonyl group, R19 is a hydrogen atom, a halogen atom, a cyano group or the like, Q is a phenyl group which may be substituted or a condensed hetero ring which may be substituted}, a herbicide containing it and an intermediate for its production, are provided. The herbicide of the present invention exhibits excellent herbicidal effects against various weeds which cause trouble in upland fields, for example, broad leaved weeds such as pale smartweed, slender amaranth, common lambsquaters, common chickweed, velvetleaf, prickly sida, hemp sesbania, pitted morningglory and common cocklebur, perennial and annual cyperaceous weeds such as purple nutsedge, yellow nutsedge, Cyperus brevifolius and rice flatsedge, and gramineous weeds such as barnyardgrass, Digitaria ciliaris, green foxtail, annual bluegrass, Johnsongrass, blackgrass and wild oat, over a wide range from the pre-germination to the growing stage. The herbicide of the present invention can further control annual paddy weeds such as barnyardgrass, smallflower umbrellaplant and monochoria and perennial paddy weeds such as Japanese ribbon wapato, arrowhead, flat sedge, water chestnut, bulrush and narrowleaf waterplantain. On the other hand, the herbicide of the present invention is highly safe to crop plants and shows high safety especially to rice, wheat, barley, corn, sorghum, soybean, cotton and sugar beet.

  由通式代表的吡啶酮衍生物： 其中 R 是烷基或卤代烷基，R1 是氢原子、烷基、卤代烷基、乙酰基、氨基、烷氧基羰基氨基、烷基羰基氨基或类似基团，R2 是氢原子、烷基、羧基或烷氧基羰基，R19 是氢原子、卤素原子、氰基或类似基团，Q 是苯基或类似基团、R19 是氢原子、卤素原子、氰基或类似基团，Q 是可被取代的苯基或可被取代的缩合杂环}，本发明提供了含有这些基团的除草剂及其生产中间体。 本发明的除草剂对各种给高地田带来麻烦的杂草有很好的除草效果，例如，阔叶杂草，如苍耳草、纤细苋、普通羔羊草、普通鸡冠花、绒毛草、刺五加、麻矢车菊、洼地牵牛花和普通鸡冠花、多年生和一年生禾本科杂草，如紫花地丁、黄花地丁、香附子和稻飞虱，以及禾本科杂草，如稗草、Digitaria ciliaris、绿狐尾、一年生蓝草、约翰逊草、黑穗禾和野燕麦。本发明的除草剂还能进一步防除一年生水稻杂草，如稗草、小花伞草和芒草，以及多年生水稻杂草，如日本带状禾本科杂草、箭杆草、平莎草、荸荠、牛筋草和狭叶水田芥。 另一方面，本发明的除草剂对作物植物非常安全，尤其是对水稻、小麦、大麦、玉米、高粱、大豆、棉花和甜菜。
