Applications

Fipronil is a phenyl pyrazole insecticides, broad spectrum insecticide, stomach poison to insects to the main contact and some both within the suction effect, its mechanism is to hinder the insect insecticidal γ-ammonia kidding Control of chloride acid metabolism. Therefore, aphids, leafhoppers, planthoppers, Lepidoptera larvae, flies and other important pests Coleoptera have a high insecticidal activity, no injury to crops. The agent can be applied to the soil, can also be foliar spray. Applied to the soil to effectively control maize roots and leaves A, wireworms and cutworms. When sprayed on the diamondback moth, cabbage butterfly, such as rice have high level of thrips control efficacy,and persistence length. It can be used to synthesize of many fluoro-containing surfactants and chemicals.
