| Abstract: | The filamentous fungi Gliocladium spp.has potential as a biocontrol agent against many pathogens.The objective of this study was to evaluate the effects of ferment filtrate and volatile metabolites of G.roseum on egg hatching and juvenile mortality of Meloidogyne incognita.The nematode egg hatching rates and juvenile activity for treatments with volatile metabolites and with 0 ×,5 ×,10 ×,20 × and 40 × dilutions of the G.roseum culture filtrate were measured in this test.Results showed that G.roseum ferment filtrate inhibited nematode egg hatching and juvenile mortality by 80.4％ and 32.0％,respectively.Dilution of ferment filtrate reduced the inhibition of nematode egg hatching and the juvenile activity.Volatile metabolite of G.roseum also inhibited nematode egg hatching and juvenile activity.G.roseum can be used as a biocontrol agent against plant parasitic nematodes. |
