  The present invention relates to a compound of formula (I): wherein: X is methyl or chlorine; R1 is fluorine or bromine; R2 is ethynyl, C1-C3alkoxy, C1-C3haloalkoxy, or C1-C3alkoxy-C1-C3alkoxy-; and Q is a pyran-3,5-dione-4-yl, a thiopyran-3,5-dione-4-yl, a piperidine-3,5-dione-4-yl, a cyclopentane-1,3-dione-2-yl, a cyclohexane-1,3, 5-trione-2-yl, a cyclohexane-1,3-dione-2-yl, or a cycloheptane-1,3-dione-2-yl, or a derivative thereof (e.g. a fused such as fused bicyclic derivative, and/or a spirocyclic derivative), or an enol ketone tautomer derivative thereof, wherein Q is further defined herein; and wherein the compound of formula (I) is optionally present as an agrochemically acceptable salt thereof. Preferably, X is methyl; and/or R1 is fluorine; and/or R2 is -O-R2A, wherein R2A is methyl, ethyl, trifluoromethyl, difluoromethyl, trifluoroethyl, or -CH2CH2OCH3. These compounds are suitable for use as herbicides. The invention therefore also relates to a method of controlling weeds, especially grassy monocotyledonous weeds, in crops of useful plants, comprising applying a compound of formula (I), or a herbicidal composition comprising such a compound, to the weeds and/or to the plants and/or to the locus thereof.

  本发明涉及一种具有以下结构的化合物（I）：其中：X是甲基或氯；R1是氟或溴；R2是乙炔基，C1-C3烷氧基，C1-C3卤代烷氧基，或C1-C3烷氧基-C1-C3烷氧基；Q是吡喃-3,5-二酮-4-基，硫代吡喃-3,5-二酮-4-基，哌啶-3,5-二酮-4-基，环戊二酮-2-基，环己三酮-2-基，环己二酮-2-基，或环庚二酮-2-基，或其衍生物（例如，融合的如融合的双环衍生物和/或螺环衍生物），或其烯醇酮互变异构体衍生物，其中Q在此进一步定义；化合物（I）可作为农药接受的盐存在。优选，X是甲基；和/或R1是氟；和/或R2是-O-R2A，其中R2A是甲基，乙基，三氟甲基，二氟甲基，三氟乙基，或-CH2CH2OCH3。这些化合物适用于作为除草剂使用。因此，本发明还涉及一种控制杂草，特别是草本单子叶杂草，在有用植物作物中的方法，包括将化合物（I）或含有该化合物的除草剂组合物施用于杂草和/或植物和/或其生长环境。
