Nematicidal effect of fosthiazate on eggs and second stage juveniles(J2) of Meloidogyne incognita were tested in vitro.Its effects on J2 motility and infectivity were evaluated with a sand column and the staining method respectively.The results showed that J2 mortality was significantly increased while the egg hatching,J2 motility and infectivity were significantly reduced with the increasing concentration and time after treatment of fosthiazate.The egg hatching in individual and in egg masses were reduced by 72.51% and 77.75%,respectively after treatment with 200 μg/mL fosthiazate for 24 h.The J2 mortality was 80.13% after treatment with 200 μg/mL fosthiazate for 24 h.The J2 migrated 0.1 cm in 7 d in sand column mixed with 25 μg/mL fosthiazate while it did 1.04 cm in the control.The infectivity of J2 after treatment with 100 μg/mL fosthiazate for 48 h was 0.51% while it was 21.85% in the control.It proved that fosthiazate have great potential on the inhibition of egg hatching,J2 motility and infectivity of Meloidogyne incognita.
