Environmental Precautions
Krovar I is toxic to aquatic organisms. Do not apply directly or indirectly to aquatic habitats.
Runoff
:
Avoid contamination of aquatic areas as a result of runoff.
Leaching
:
The use of this chemical may result in contamination of groundwater, particularly in areas where soils are
permeable (e.g. sandy soil) and/or where the depth to the water table is shallow.
Drift
:
Apply only when the potential for drift is minimal. A buffer zone of 15 metres is required from sensitive
aquatic habitats < 1m in depth and 10 metres when water depth is > 1m. A buffer zone of 60 metres is required
between the point of direct application and the closest downwind edge of sensitive terrestrial habitats.
Toxicity
Very low acute mammalian toxicity. Acute oral LD
50
(
rats) = bromacil 5,200 mg/kg, diuron = 3,400 mg/kg. Non-toxic
to birds. Toxic to fish.
