Recently amino acid derivatives have received attention as efficacious pesticides against the plant pathogen. In this report, several amino acid derivatives were tested for their antibiotic effects upon the plant pathogen. Following amino acid derivatives were synthesized: N-benzoyl-L-valine, N-benzoyl-L-leucine, N2, N6-dibenzoyl-L-lysine, N-benzoyl-L-isoleucine, N-phenyl-acetyl-L-valine, N-phenylacetyl-L-leucine, N2, N6 -diphenylacetyl-L-lysine, N-phenylacetyl-L-isoleucine. Then the screening tests of these compounds were carried out with sheath blight of rice plant, anthracnose of banana, etem rot of banana, black spot of pear, gray mold of cucumber. Results showed N-benzoyl-L-leucine caused a significant inhibition in concentration of 0.1mM to the colony appearance of anthracnose of banana and black spot of pear respec-tively. Other derivatives have some antibiotic activities to the plant pathogen, but these might be of no practical value because of the weak activities.
