Abstract

To find new pesticidal lead compounds with high bioactivity, 26 new pyrazines emicarbazide derivatives were designed and synthesized by combining with the pyrazine ring and semicarbazide. Their structures were confirmed by 1H NMR, FTIR and MS techniques. The herbicidal activities of these compounds were evaluated. The bioassay results showed that the post-emergence inhibitory rate of 4m reached 80% on Amaranthus retroflexus and Eclipta prostrata at 150 gai/ha.

Key words： pyrazine; semicarbazide; synthesis; herbicidal activity
