Disinfection formulation and disinfection method
An anticoccidial disinfection formulation containing a compound represented by general formula (I) below as an active ingredient: R 1 —N═C═S (I) [In formula (I), R 1 represents an alkenyl group having 2 to 8 carbon atoms or the like] This compound has a high sporulation inhibitory activity against coccidian oocysts and is thus effective for eradicating coccidians and for disinfecting rearing facilities and rooms of host animals, such as a livestock barn and a poultry house.
1. A disinfection formulation, comprising:
a aqueous mixture of active ingredients consisting of 200 mg/L or greater of a compound of formula (I) and from 10 to 500 mg/L of a compound of formula (II):
R 1 —N═C═S (I)
wherein R 1 represents an alkenyl group having 2 to 8 carbon atoms, an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or a cycloalkyl group having 3 to 6 carbon atoms:
wherein R 2 and R 3 each independently represent an alkyl group having 8 to 16 carbon atoms,
and a sporulation rate of coccidian oocysts in cows when contacted with the aqueous solution is 0%.
2. The disinfection formulation according to claim 1 , wherein the compound of formula (II) is at least one selected from the group consisting of dioctyldimethylammnonium chloride, octyldecyldimethylammonium chloride, didecyldimethylammonium chloride, dicetyldimethylammonium chloride, and dilauryldimethylammonium chloride.
