General Description

2,4,5-trichlorophenyl 4-methylbenzenesulfonate, also known as sulcotrione, is a selective herbicide commonly used to control broadleaf and grassy weeds in corn and other crops. It works by inhibiting the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD), which is essential for the biosynthesis of carotenoids in plants. This inhibition leads to the accumulation of toxic intermediates, causing the death of the targeted plants. Sulcotrione is a white crystalline solid that is sparingly soluble in water and is typically applied as a post-emergence herbicide in the form of a spray or granules. It has low toxicity to mammals and other non-target organisms, making it a suitable option for weed control in agricultural settings.
