ANASAC MAGNETO 45 SC is an insecticide combining two active ingredients: Fipronil and Imidacloprid. Fipronil, from the phenylpyrazole group, is a broad-spectrum insecticide that disrupts the insect’s central nervous system by blocking the passage of chloride ions through the GABA receptor, causing hyperexcitation of muscles and nerves. It acts mainly by contact. Imidacloprid is a neonicotinoid that inhibits nicotinic receptors in the nervous system. It has primarily systemic action, providing strong plant protection and controlling piercing and sucking insects.
