Chemical compound
Defenuron is an obsolete herbicide. Its formula is C8H10N2O.[1] It is an urea herbicide and was once produced as a wettable powder to control undesirable grasses and broad-leaved plants in a variety of crops.[2] It enters plants via diffusion and moves through the xylem.[3] It is highly water-soluble, is of low toxicity to fish, and does not pose a significant health hazard to mammals[2] or to Japanese quail.[4]
