Abstract：
:Benzoylcyclohexanedione herbicides work by inhibiting 4-hydroxyphenylpyruvate dioxygenase which was the last new target site introduced for herbicides. In an attempt to find new 4-hydroxyphenylpyruvate dioxygenase inhibitors with high efficacy and selectivity, a novel benzoylcyclohexanedione compound SYP-9121 was synthesized and studied in greenhouse and field. In the greenhouse, SYP-9121 showed broad spectrum herbicidal activity and good safety to maize. Its control of barnyard grass, crabgrass, redroot pigweed, purslane, dayflower and night shade was equivalent to that of the commercial herbicide mesotrione. Three field trials in summer maize showed that SYP-9121 could efficiently control both grass and broadleaf weeds with good selectivity. Herbicidal activity of SYP-9121 was comparable to that of mesotrione.
