Application

Fipronil is a insecticide which acts as a blocker of the GABA-regulated chloride channel. Insects resistant or tolerant to pyrethroid, cyclodiene, organophosphorus and/or carbamate insecticides are susceptible to fipronil. A broad-spectrum insecticide, toxic by contact and ingestion. Limited xylem systemicity in some monocotyledonous crops. Can be used to control insects when applied as a soil or seed treatment.
To control multiple species of thrips on a broad range of crops by foliar, soil or seed treatment. Control of corn rootworm, wireworms and termites by soil treatment in maize. To control boll weevils and plant bugs on cotton, diamond-back moths on crucifers, and 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.
