| Abstract: |
| To investigate the bio control resources and obtain better effective antagonistic fungi to control root knot nematode, 118 vegatable root samples infected by root knot nematodes were collected from 9 counties of Shaanxi Province. 199 antagonistic fungal isolates were isolated respectively from eggs, egg masses and females of root knot nematodes. These antagonistic fungi were identified to 22 genera, including Fusarium, Cephalosporiopsis, Paecilomyces, Cladosporium, Alternaria, Drechmeria, Monacrosporium, Penicillium etc and 43 sterile fungi. The isolation frequency of Fusarium spp., Cephalosporiopsis spp. and Cladosporium spp. took up 53%, and the species and the amount of antagonistic fungi of different samples were distinctly different in the regions. |
