Reference information from e-Pesticide Manual 2.0
FIPRINIL is a broad use insecticide that belongs to the phenylpyrazole chemical family. Fipronil kills insects when they eat it or come in contact with it. Fipronil works by disrupting the normal function of the central nervous system in insects. Fipronil is used to control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects.
· There is target site specificity between insects and mammals, with Fipronil displaying tighter binding (i.e., higher potency) in the insect GABA chloride channel than mammals, providing useful selective toxicity.
· Fipronil has both contact and ingestion activity, but is particularly effective by way of ingestion. The rapid knockdown effect associated with some insecticides is absent in Fipronil and insect mortality may appear to be moderately slow. However, intermediate responses, such as cessation of feeding, may be noted soon after treatment. Residual control following foliar application is in general good to excellent
· The site of action of Fipronil sets it apart from most commercial insecticides. a new generation insecticide belonging to new family of Phenyl Pyrazole
· Fipronil application has shown demonstrable Plant Growth Enhancement (PGE) effect in many crops
