Claims17
A method of combating bacteria or fungi which comprises applying thereto a bactericidally or fungicidally effective amount of a compound of the formula ##SPC13##
- wherein X is halogen;
- each of X.sub.1, X.sub.2, X.sub.3 is hydrogen or halogen;
- Y is hydrogen, halogen or methyl;
- each of Y.sub.2 and Y.sub.3 are hydrogen or halogen and wherein at least two of X.sub.1, X.sub.2, X.sub.3, Y, Y.sub.2 and Y.sub.3 are not hydrogen.
A method for protecting organic materials against the action of bacteria or fungi, which comprises impregnating said material or applying to the surface of said material a bactericidally or fungicidally effective amount of a compound of the formula ##SPC15##
- wherein X is halogen;
- each of X.sub.1, X.sub.2 and X.sub.3 is hydrogen or halogen;
- Y is hydrogen, halogen or methyl;
- each of Y.sub.2 and Y.sub.3 are hydrogen or halogen;
