Title: Toxicity comparison of thirteen phytochemicals to Meloidogyne incognita
Abstract: The toxicity of thirteen phytochemicals to Meloidogyne incognita Chitwood was compared by bioassay and the influence of UV radiation on nematicidal activity of these compounds was also studied.The results showed that the nematicidal activity of hydroquinone,DL-menthol,eugenol and aloperine to M.incognita was the highest,that of pyrocatechol,sophoramine, matrine,phloroglucinol,citrazinic acid and citronellol was the second,while cytisine,physostigmine and resorcinol showed poorly nematicidal activity.The nematicidal toxicity of aloperine and citrazinic acid to the pest was obviously debased with UV radiation,and that of the other phytochemicals was not effected by UV radiation.
