| Description | Benzobicyclon is a 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) inhibitor and herbicide that is spectrally active against annual grasses, sedges, and broadleaf weeds without toxicity to rice. |
| In vitro | Under greenhouse paddy conditions, the herbicidal activity of Benzobicyclon (200–300 g a.i./ha, 6% flowable) was evaluated in pot tests. Applied at pre-emergence and 1-leaf stage, Benzobicyclon effectively controlled Echinochloa crus-galli, Scirpus juncoides, Monochoria vaginalis, Lindernia dubia var. dubia, and Cyperus serotinus, with no phytotoxicity to transplanted rice. Less effective against Sagittaria pygmaea (requiring 600 g/ha)[1]. |
