Selective, post emergence herbicide, acting primarily through foliar uptake with little or no soil activity. Symptoms of chlorosis appear in affected weeds in days with necrosis and death occuring after 10-25 days under optimal conditions. |
|
Characteristics and Uses: |
Post-emergence control of broad-leaved weeds in cereal crops, including wheat, barley, oats, rye and triticale, at 7.5-30 g/ha. |

Toxicity: |
Oral: Acute oral LD50 for rats >5000 mg/kg. Skin and eye: Acute percutaneous LD50 for rabbits >5000 mg/kg. Non-irritating to skin and eyes (rabbits). Mildly sensitising to skin (guinea pig maximisation test), but not likely to be a dermal sensitisation risk to humans. Inhalation: LC50 (4 h) for rats >5.0 mg/l air. |
