It shows selectivity in barley, cotton, peanuts, sugar beet, wheat and several brassica crops. Effective rates range from 1.0-4.5 kg/ha. Activity is dependent on water availability such as rainfall following treatment, overhead irrigation or applications to standing water as in rice culture.  Phytotoxicity  Non-phytotoxic to rice, cotton, barley, wheat, peanuts, sugar beet, and some brassicas.
