PURPOSE:A virucide capable of being used in a large amount for disinfection, stock raising, and agriculture, comprising lignin,especially lignin of a needle- leaf tree as an active ingredient. CONSTITUTION:A virucide comprising lignin, preferably lignin of a needle-leaf tree, especially lignin derived from a Japan cedar as an active ingredient. Having infection ingibiting action on an animal virus such as IBR (Infectious Bovine Rhinortachieitis) virus, bovine adeno virus, bovine enterovirus, parainfluenza virus, etc. and a plant virus such as tabacco mosaic virus, etc., usable for disinfection, stock raising, and controlling agent for agriculture. Preferably useful as a solution suitable for a large amount of use, and a large amount of application, its amount used is 0.005-10.0wt% for disinfection or stock raising and preferably as a solution containing 0.0005-1.0wt% fat-soluble lignin for agriculture (foliar application). |
