## Abstract

This invention is directed to a broad spectrum fungicide/algaecide composition which comprises a mixture of (a) at least one halopropynyl compound and (b) at least one sulfur-containing s-triazine, said mixture provided in an amount to prevent and/or protect a substrate from attack by one or more fungal and/or algael organisms. The composition can be used broadly in industrial systems and more particularly with substrates such as paints, coatings, stucco, concrete, stone, cementaceous surfaces, wood, caulking, sealants, textiles, and the like.

## Claims

### Claim 1

A biocidal composition comprising a mixture of a halopropynyl compound and a sulfur-containing s-triazine in a proportion that exhibits a synergistic biocidal activity, wherein said halopropynyl compound is 3-iodo-2-propynyl butyl carbamate and wherein said sulfur-containing s-triazine is 2-methylthio-4-tert-butylamino-6-cyclopropylamino-s-triazine and wherein the halopropynyl compound and the sulfur-containing s-triazine are each present in a synergistic effective mount of from about 1 part halopropynyl compound to 9 parts s-triazine to about 9 parts halopropynyl compound to 1 part s-triazine.

### Claim 2 (depends on 1)

The composition of claim 1 containing from about 0.004% to 2.0% of the mixture of said halopropynyl compound and said s-triazine.

### Claim 3 (depends on 1)

The biocidal composition of claim 1 wherein said synergistic effective mount comprises from about 1 part halopropynyl compound to 2 parts s-triazine to about 2 parts halopropynyl compound to 1 part s-triazine.

### Claim 4 (depends on 3)

A method for protecting a substrate from fungal or algael infestation comprising treating said substrate with a biocidally effective amount of the composition of claim 3.

### Claim 5 (depends on 1)

A method for protecting a substrate from fungal or algael infestation comprising treating said substrate with a biocidally effective amount of the composition of claim 1.

### Claim 6

A biocidal composition comprising a solution of a halopropynyl compound and a sulfur-containing s-triazine in a suitable solvent, wherein the halopropynyl compound and the sulfur-containing s-triazine are in a proportion that exhibits a synergistic biocidal activity, wherein said halopropynyl compound is 3-iodo-2-propynyl butyl carbamate and wherein said sulfur-containing s-triazine is 2-methylthio-4-tert-butylamino-6-cyclopropylamino-s-triazine and wherein the halopropynyl compound and the sulfur-containing s-triazine are each present in a synergistic effective amount of from about 1 part halopropynyl compound to 9 parts s-triazine to about 9 parts halopropynyl compound to 1 part s-triazine.

### Claim 7 (depends on 6)

The biocidal composition of claim 6 wherein said synergistic effective amount comprises from about 1 part halopropynyl compound to 2 parts s-triazine to about 2 parts halopropynyl compound to 1 part s-triazine.

### Claim 8 (depends on 7)

A method for protecting a substrate from fungal or algael infestation comprising treating said substrate with a biocidally effective amount of the composition of claim 7.

### Claim 9 (depends on 6)

A method for protecting a substrate from fungal or algael infestation comprising treating said substrate with a biocidally effective amount of the composition of claim 6.
