Control of emergent and submerged aquatic weeds. Weed control on non-crop land. Weed control and tassel inhibition in sugar cane.
ENVIRONMENTAL FATEAnimals In rats, following oral administration, only a small proportion was absorbed. The unabsorbed dose was excreted rapidly in faeces, and the absorbed dose extensively and rapidly excreted in urine.
Plants Metabolic breakdown of
diquat dibromide is very limited in plants. On plant surfaces, photochemical degradation occurs.
Soil/Environment Diquat is rapidly and strongly adsorbed to soil and sediment (
KOC values between 2000 and 7900000 ml/g), resulting in complete deactivation. When adsorbed to soil,
diquat is slowly degraded with
DT50 values ranging from 1.2 to 41 y. When desorbed, it is quickly degraded by soil micro-organisms (DT
50 of unadsorbed
diquat ranged between 0.4 and 21 d). The potential risk to leach into groundwater is negligible.
