General description

Acetochlor is a chloroacetanilide herbicide effective against soil bacteria. This selective pre-emergence herbicide inhibits the elongation of C18 and C16 fatty acids species to form very long-chain fatty acids (VLCFAs). It is commonly used for weed control management and yellow nutsedge in corn plantation.

Application

Acetochlor may be used as a reference standard to deternine acetochlor in water and soil samples using high-performance liquid chromatography and reversed-phase liquid chromatography coupled with electrospray ionization mass spectrometry, respectivley.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Atrazine and other corn herbicides are routinely detected in drinking water. Two studies on potential association of atrazine with small-for-gestational-age (SGA) and preterm birth prevalence found inconsistent results. Moreover, these studies did not control for individual-level potential confounders. Our retrospective
