Abstract
Abstract New aminophenylcarbamates of the formula WHEREIN R1 represents an alkyl residue containing not more than three carbon atoms and R2 an alkyl residue containing two to four carbon atoms, have very good properties in combating insects and members of the order Acarina, but they possess especially outstanding properties in destroying blood-sucking arthropodes. These carbamates may be used as active ingredients in pesticidal preparations.
