Abstract

Use of 4,4'-bis-(6"-2,5-disulfophenylamino-4'-diethanolaminotriazinyl-2"-amino)-stilbene-2,2-disulfonic acid and/or its salts as active ingredients of an insecticidal composition, especially for controlling ants of the pharaonic type. The composition is applied as a 5- to 25%, preferably 10% solution of the active ingredient in water. The solution is placed in a container on the floor.

Description

(54) Anticides

Use of 4,4'-bis- (6 "-2,5-disulfophenylamino-4" -dietanolaminotriazinyl-2 "-amino) -stilbene-2,2-disulfoic acid and / or salts thereof as an active ingredient of an insecticidal composition, particularly for the control of ants of the faranoid type. The composition is applied as a 5- to 25%, preferably 10% solution of the active ingredient in water. The solution is placed in a container on the floor.

AND

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anticidal agent, in particular of the faranoid type, found in living areas.

Heretofore, insecticidal compositions based, for example, on pirinidine compounds with a phosphoric acid ester have been used to control these insects routinely. These substances are hazardous in their toxicity and therefore require careful handling and special precautions when controlling extensively. In addition, agents based on the hormonal action of certain substances are known. Their application is also more complicated and brings effect only after a long-term effect.

It has now surprisingly been found that for controlling ants, especially faranoidního type composition may be used whose active component consists of 4,4'-bis -. (6 "-2,5-disulfophenylamino-4 ^{'-dietanol-2-aminotriazinyl} '-Amino] -stilbene-2,2-disulfoacids, and / or salts thereof hitherto used as optically brighteners in the textile and paper industry, these are substances which are commonly produced and are used in the daily practice of refining processes In the bath of optically brightening agents, most of the white assortment of the textile and paper industry is processed.

For use, the composition is applied as an aqueous solution of an optic brightener at a concentration of 5 to 25 g / l, preferably 10 g / l, which is prepared by conventional dissolution in water. After cooling, it is poured into a container that is well washed and free of odors. Ants are attracted by this means and gather on the surface from where they cannot escape. When the insects accumulate on the surface, it is sufficient to remove the layer from the surface. The solution continues to act. When standing for a long time, water and solution gradually evaporate. In this case, it is sufficient to make up to the original volume with water.

Example g 4,4'-Bis- (6'-2,5-disulfophenylamino-4'-diethylaminotriazinyl-2'-amino) -stilbene-2,2-disulfoic acid hexasodium salt, manufactured under the trade name Rylux BSU, was dissolved in 1 1 hot distilled water. After cooling, this solution was poured into six washed glass containers of volume and placed on the floor in rooms with the appearance of faranoid ants. After several hours (overnight) a layer of ants proportional to the amount of parasite occurring on the surface of the solution. The newly designed formulation is less toxic than commonly used formulations and does not require special handling. As an aqueous solution, it can be prepared easily and anywhere, its activity is long-lasting. Therefore, they are particularly suitable for use in living areas and households.
