Diflubenzuron is a direct-acting insecticide normally applied directly to plants or water. Diflubenzuron, besides its use in agriculture, horticulture and forestry against larvae of Lepidoptera, Coleoptera, Diptera, Hymenoptera, and in public health against larvae of mosquitoes, is used as a veterinary drug for the treatment of sea lice infestations in Atlantic salmon. Diflubenzuron acts by interference with the synthesis of chitin. It is reported that public exposure to diflubenzuron through either food or drinking-water is negligible.

Acetophenone is an organic compound with major use in the chemical industry for the polymerization of olefins, and organic synthesis as a photosensitizer and as a specialty solvent for plastics and resins. It is also a chemical intermediate for the odorant ethyl methyl phenylglycidate, the riot control agent 2-chloroacetophenone and 2- bromoacetophenone for dyes. It is used in the manufacture of pharmaceuticals, rubber, dyes, and corrosion inhibitors. Acetophenone was approved by the FDA as a flavoring substance and adjuvant in food. It is used as a flavoring agent in non-alcoholic beverages, ice cream, candy, baked goods, gelatins, puddings, tobacco, and chewing gum. It is used to impart an orange-blossom fragrance in soaps, detergents, creams, lotions, and perfumes.
