Toxicity: |
Acute oral LD50 for rats, 82mg/kg; acute dermal LD50 for rats,
1100mg/kg; LD50 for dogs, 320mg/kg. Some what degree of
cholinesterase inhibition occurred after feeding dogs at 100mg/kg
for 3 months; non-effect level for rats, 1mg/kg; LC100(48 hours) for
crucian (Carassius auratus), 8.4mg/l; 1mg/l for carp (Cyprinus
carpio). Toxic to bees and fish.

Application: |
A broad spectrum insecticide and acaricide
with some nematicidal properties. It controls aphididae
in cereals at 320-600 g AI (20% EC)/ha, in fruit at 75-125 g/100l.
When incorporated at 1-2 kg AI (20% EC)/ha in the soil prior to
planting, it controls Agrotis spp. and other cutworms. It can
penetrate plant tissue, but has no systemic activity.
