Tepraloxydim (CAS 149979-41-9)

Tepraloxydim, an herbicide belonging to the cycloxydim family, is widely utilized to effectively control annual and perennial grasses as well as broadleaf weeds in various crops. The broad spectrum of grasses and broadleaf weeds that can be controlled by tepraloxydim has led to its application in both pre- and post-emergence scenarios. Researchers have also investigated its impact on crop yields and its ability to reduce weed populations in diverse cropping systems. Tepraloxydim exerts several biochemical and physiological effects on weeds, such as inhibiting photosynthesis, disrupting cell division, and impeding respiration. Moreover, it has been observed to decrease the production of chlorophyll and other pigments, resulting in leaf yellowing and eventual death. The mode of action of tepraloxydim involves the inhibition of acetolactate synthase (ALS), an enzyme critical for the synthesis of branched-chain amino acids. By disrupting the growth and development of weeds, tepraloxydim effectively leads to their demise.
