GHS Hazard Classification

Documented Uses

• Used to control algae, fungi, and bacteria in ornamental aquaria and commercial and industrial circulating water systems; Also used as broad-spectrum herbicide for maize, cereals, vines, fruits, coffee, potatoes, sugar cane, rubber, forestry, and other crops; [HSDB]
• Registered strictly for aquatic non-food uses in the US; [EPA REDs]
• Terbuthylazine was registered in the United States in 1975. Tolerances were established for terbuthylazine in or on corn fodder and forage, corn grain (including popcorn grain), and sorghum forage and grain (40 CFR 180.333). However, since no end-use products were registered for use of terbuthylazine as a herbicide these tolerances were revoked in 1992 … Products formulated for end-use were registered as algicide and microbicides/microbistats starting in 1986.
• Terbuthylazine is an algicide, a microbicide and microbistat used to control algae and slime-forming algae, fungi, and bacteria. … It is labeled for aquatic non-food industrial, commercial, and residential uses. Industrial and commercial uses are for ornamental fountains, ponds, and for water cooling systems, including evaporative condensers, heat-exchange systems, and commercial and industrial cooling towers. Residential uses are for ornamental ponds/aquaria.
• Broad-spectrum pre- or post-emergence weed control in maize, sorghum, vines, fruit trees, citrus, coffee, oil palm, cocoa, olives, potatoes, peas, beans, sugar cane, rubber, and in forestry in tree nurseries and new plantings. It remains largely in the topsoil, controlling a wide range of weeds, at rates of 0.6-3 kg/ha; high rates are only recommended as band applications. In Europe, used mainly on maize and sorghum.
• Microbiocides, Algicides, Herbicides
