This study was conducted to obtain some informations on the relationship between chemical structures of some new types of amine derivative such as N-haloalkyl-benzyl-amine, N-alkyl-benzylamine, N-phenoxyalkyl-2-halogenopropylamine and N-phenylthioal-kyl-2-halogenopropylamine and their plant physiological activities. (1) In these amine derivatives, HCl salts of N-phenoxyalkyl-2-halogenopropylamine derivatives showed the highest activity for the tested plants. They were found to be more effective when they had one chlorine in the 4 position of benzene ring and the number of methylene group linked to 2-chloropropylamine was 2, 5 or 6. (2) The chlorosis activity specific to these compounds was the most remarkable when they had both of phenyl and 2-halogenopropylamine groups in their structure. (3) Atom linked to benzene ring had important influence on activity. Descending order of activity was as follows: O>C>S. (4) These compounds had lower acute toxicity to fish than sodium pentachlorophenoxide and lower mobility in soil. (5) These compounds were much stable to ultraviolet rays.
