The compounds of formula I and their use as fungicides in the crop protector sector exclusively are claimed per se in copending Canadian patent application no. 512,548 filed on June 26, 1986.
In accordance with the invention, it has how-ever been found and proved that the compounds of formula I are also suitable for combating algae, bacteria and fungi outside the crop protection sector, for example for disinfecting water in air-humidifying units, cooling-water circulation systems, water injection systems and for oilfields, swimming baths, laundries, and in prepara-tions used for disinfection in the food sector, dairies, breweries, hospitals, etc. The treatment of raw hides and leather is also worthy of mention.

':'''~' ..........
~X894~9 BASF Aktiengesellschaft ~ . 0~5C 3 The compounds according to the invention may be con-verted into the usual formulations, e.g. solutions, emul-sions, suspensions, dusts, powders, pastes and granules.
The application forms depend entlrely on the purpose for 05 which the agents are belng used; at all events they must ensure a fine and uniform distributlon of the active ingredients. The formulations are prepared in conventional manner, e.g., by extending the active ingredlent with solvents and/or carriers, if desired using emulsifiers and dispersants. Where water is used as diluent, other organlc solvents may also be employed as auxlliary solvents. Sult-able compounds for preparlng such formulatlons are sol-vents such as aromatlcs (e.g., xylene, benzene), chlorlnated aromatlcs (e.g., chlorobenzenes), paraffins (e.g., petroleum fractlons), alcohols (e.g., methanol, butanol), amlnes (e.g., ethanolamlne, dlmethylformamlde), and water; carrlers such as natural rock flours (e.g., kaollns, dlatomaceous earth, talc, chalk) and synthetic rock flours (e.g., hlghly dlsperse slllclc acld, 8111-cates); emulslflers such as nonlonlc and anionlc emulsify-lng agents (e.g. polyoxyethylene-fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dlspersants such as llgnln, sulflte waste llquors and methyl cellulose.
12 ~9 ~ 9 BAS~ AXtiengesellscha~ 12 - J-Z` 0050 3Q! _ The active lngredients per se are low-foam biocides. A
significant increase in the effectiveness of biocidal preparations containing these compounds is achieved by adding tri-C6_12-alkylmethylammonium salts, preferably in 05 amounts of from 20 to 40 wt%, based on the weight of compounds of the general formula I.
The compounds according to the invention whlch are contalned in such preparatlons are effectlve agalnst a large number o~ mlcroorganlsms, for example:
Staphylococcus aureus, Escherichia coll, Klebsielle pneumoniae, Citrobacter freundli, Proteus vulgaris, Pseudomonas aeruglnosa, Desulfovibrlo desulfuricans, Streptovertlcllllum rubrlretlculi, Asperglllus nlger, Asperglllus verslcolor, Penlcllllum funlculosum, Penlcllllum expansum, Penicllllum glaucum, Paecllomyces varlotll, Trlchoderma vlrlde, Chaeto~lum globosum, Candlda alblcans, Trlchophyton mentagrophytes, Geotrlchum candldans, Monllla sltophlla, Scenedesmus quadrlcauda, Chlorella vulgarls, Nostoc muscorlum, Osclllatorla llmosa und Anabaena constrlcta.
Usual use concentrations are 0.01 to 2% of active lngredlent, based on the welght of the material to be protected; when the actlve ingredlents are used for treatlng water or in the productlon of oil, ln swlmmlng baths, coollng towers, alr humldlfylng unlts or ln the paper lndustry, amounts o~ 5 to 250 ppm are sufflclent.
Ready-to-use dlslnfectant solutlons contaln, for example, from 0.5 to 10 wt% actlve ingredlent. The actlve lngredlents may also be mlxed wlth other, prlor art, mlcroblcldes. In many cases a synerglstlc effect is produced.

~X894~9 BASF Aktiengesellschaft ~ . 0~5C 3 The compounds according to the invention may be con-verted into the usual formulations, e.g. solutions, emul-sions, suspensions, dusts, powders, pastes and granules.
The application forms depend entlrely on the purpose for 05 which the agents are belng used; at all events they must ensure a fine and uniform distributlon of the active ingredients. The formulations are prepared in conventional manner, e.g., by extending the active ingredlent with solvents and/or carriers, if desired using emulsifiers and dispersants. Where water is used as diluent, other organlc solvents may also be employed as auxlliary solvents. Sult-able compounds for preparlng such formulatlons are sol-vents such as aromatlcs (e.g., xylene, benzene), chlorlnated aromatlcs (e.g., chlorobenzenes), paraffins (e.g., petroleum fractlons), alcohols (e.g., methanol, butanol), amlnes (e.g., ethanolamlne, dlmethylformamlde), and water; carrlers such as natural rock flours (e.g., kaollns, dlatomaceous earth, talc, chalk) and synthetic rock flours (e.g., hlghly dlsperse slllclc acld, 8111-cates); emulslflers such as nonlonlc and anionlc emulsify-lng agents (e.g. polyoxyethylene-fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dlspersants such as llgnln, sulflte waste llquors and methyl cellulose.
