Roles Classification
Biological Role(s): carotenoid biosynthesis inhibitor
Any pathway inhibitor that acts on the carotenoid biosynthesis pathway.
Application(s): proherbicide
A compound that, on administration, must undergo chemical conversion by biochemical (enzymatic), chemical (possibly following an enzymatic step), or physical (e.g. photochemical) activation processes before becoming the pharmacologically active herbicide for which it is a proherbicide.
agrochemical
An agrochemical is a substance that is used in agriculture or horticulture.
