Description and Uses

Bromacil (CAS 314-40-9) belongs to a class of herbicides known as uracils, first developed by DuPont in 1962. Its herbicidal activity is due to inhibition of photosynthesis in several species of weeds and brush. Since its introduction in 1962, farmers in North and South America and Asia have used bromacil-containing herbicides for crop protection.

Uracil herbicide applied to soil to control a wide variety of annual and perennial grasses, broad-leaved weeds and general vegetation on uncropped land. It is also used for selective weed control in apple, asparagus, cane fruit, hops and citrus crops.
