A herbicidal composition having an excellent weed control effect, which comprises a pyridazinone compound represented by the formula (I): wherein R
1
represents a C
1-6
alkyl group or a (C
1-6
alkyloxy)C
1-6
alkyl group, R
2
represents a hydrogen atom or a C
1-6
alkyl group; G represents a hydrogen atom, etc., Z
1
represents a C
1-6
alkyl group, Z
2
represents a C
1-6
alkyl group, n represents 0, 1, 2, 3 or 4, and when n represents an integer of two or more, each Z
2
may be the same or different, provided that the total number of carbon atoms in the groups represented by Z
1
and n×Z
2
is two or more; glyphosate or an agriculturally acceptable salt thereof; and a specific herbicide.
Derivatives of the new class of 3-hydroxy-4-phenyl-5-oxo-pyrazolines were optimized towards both herbicidal activity on key annual grass weed species and selectivity in small grain cereal crops. The generic structure can be separated into three parts for the analysis of the structure-activity relationships, namely the aryl, the dione with its prodrug forms and the hydrazine moiety. Each area appears to play distinct and different roles in overall expression of biological performance which is further beneficially influenced by adjuvant response and safener action. Pinoxaden 6, a novel graminicide for use in wheat and barley incorporating a [1,4,5]oxadiazepane ring, eventually emerged as a development candidate from the discovery and optimization process.
