Beta-branched alcohol mosquito control agent.

摘要

Disclosed is an improved method for controlling mosquitos wherein a body of water containing immature forms of mosquitos has its surface coated with a thin film of a control agent which is a non-ionic, organic material with a density less than that of water. The improvement in such method comprises coating the surface with an approximately monomolecular film of a beta-branched alcohol of the following structure:

The activity of the beta-branched alkanols can be enhanced by forming the alkoxylates thereof.
