In the search for new synthetic nematicides, eight piperazine derivatives were prepared. These compounds, and also two commercially available piperazine derivatives and piperazine, were submitted to a biological assay to evaluate their activity against the phytonematodes Meloidogyne incognita and Heterodera glycines. At the concentration of 20 mug mL-1, the compounds caused 3 to 73% mortality of M. incognita and 7 to 58% mortality of H. glycines.
