General Description

1,1-dimethyl-3,3-diprop-2-en-1-ylurea is a chemical compound with the molecular formula C9H18N2O. It is a urea derivative that is used as a selective herbicide in agriculture. 1,1-dimethyl-3,3-diprop-2-en-1-ylurea inhibits the photosystem II (PSII) electron transport in plants, leading to the disruption of the photosynthetic process and ultimately causing plant death. Its mode of action makes it effective against a wide range of weeds, including grasses and broadleaf weeds, while being safe for most crops when used according to label instructions. However, care must be taken to minimize its impact on aquatic ecosystems, as it has the potential to leach into water bodies and harm non-target organisms.
