Metribuzin (4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5 (4H)-one) is a herbicide used both pre- and post-emergence in crops including soy bean, potatoes, tomatoes and sugar cane. It acts by inhibiting photosynthesis by disrupting photosystem II.[3] It is widely used in agriculture and has been found to contaminate groundwater.[4]
