Abstract:
Meloidogyne hapla was used as the target material to study the effects of eight compounds on the survival of M.hapla J2 at different concentrations in vitro,in order to provide basic knowledge for ecological control.The results showed that different inorganic compounds had different effect on M.hapla;and the lethality of the same compounds at different concentration was different too,with the increase of concentration,the mortality of J2 increased.While NH4HCO3,FeCl3?6H2O,CuCl2?2H2O,CuSO4?5H2O were the most sensitive among 8 compounds,and the LC50 were respectively 0.005 957，0.000 771，0.000 159，0.000 161 mol?L-1.All compounds at LC50 and LC90 had no inhibitory effect on tomato seed germination except for roots elongation in the latter stage.And the study found that the suitable pH range for survival of M.hapla J2 was 4-12.
