Mode of action:
Broad-spectrum insecticide, toxic by contact and ingestion. Moderately systemic and, in some crops, can be used to control insects when applied as a soil or seed treatment. Good to excellent residual control following foliar application.
Usage:
Control of multiple species of thrips on a broad range of crops by foliar, soil or seed treatment. Control of corn rocworm, wireworms and termites by soil treatment in maize. Control of boil weevil and plant bugs on cotton, diamond-back moth on crucifers, Colorado potato beetle on potatoes by foliar application. Control of stem borers, leaf miners, planthoppers, leaf folders/rollers and weevils in rice. Foliar application rates range from 10-80 g/ha; soil treatment rates 100-200 g/ha.
