Tembotrione is a systemic herbicide used to control a wide range of grassy and broadleaf weeds in various crops such as corn, soybeans, and sorghum. It belongs to the triketone chemical class and works by inhibiting the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD), which is essential for the biosynthesis of carotenoid pigments in plants.
Without these pigments, susceptible weeds experience bleaching and chlorosis, leading to their eventual death. Tembotrione is valued for its efficacy against tough-to-control weeds, its broad-spectrum activity, and its flexibility in different cropping systems.
However, proper application techniques and stewardship practices are essential to minimize the risk of crop injury and environmental contamination.
