Application
A broad spectruminsecticide 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.
