The effects and control objects of fipronil are as follows:

1, the role of Fipronil: Fifenil, an organic compound, is a phenylpyrazole insecticide with a wide insecticidal spectrum. It mainly acts as stomach poison to pests, and has both contact and certain absorption effects. Its mechanism of action is to hinder the chloride metabolism controlled by γ-aminobutyric acid in insects, so it has high insecticidal activity against aphids, leafhoppers, plantworms, lepidoptera larvae, flies and coleoptera. No harm to crops. Fipronil is widely used as a sanitary insecticide. Mainly used to prevent and kill cockroaches, ants and other harmful organisms.

2, Fipronil control objects: The main control objects of the drug are caterpillar, root worm, bulb nematode, slime, rice borer, cotton bollworm, brown planthopper, rice weevil, cabbage moth, cabbage moth, beetle, coccidia, Trichomonas, fruit tree mosquitoes, wheat tube aphis and other pests, the recommended dosage is 12.5-150 g/ha.
