Chemical Mechanisms & Reaction Pathways

Norflurazon functions as a carotenoid biosynthesis inhibitor, disrupting phytoene desaturase enzyme activity to prevent carotenoid formation, leading to chlorophyll photooxidation and plant bleaching.

Carotenoid Inhibition

Blocks carotenoid biosynthesis pathway

Prevents protective pigment formation
Phytoene Desaturase

Inhibits key enzyme in carotenoid synthesis

Disrupts pigment production
Chlorophyll Photooxidation

Causes chlorophyll breakdown under light exposure

Results in characteristic bleaching
Cell Death

Photooxidative damage leads to plant death

Effective pre and post-emergence control
