Metabolite Identification
Common NameImazamethabenz-methyl
DescriptionImazamethabenz-methyl is a herbicide. Activity and selectivity are due to differential de-esterification to the active parent acid in target and crop species. Imazamethabenz-methyl is used on cereals and sunflowers, especially against wild oat
