| Abstract: | In soybean cyst nematode suppressive soil,we isolated one F.graminearum(F-9) and two Fusarium oxysporumvar.redolens(F-2,F-15).The objective was to determine the effects of Fusarium.spp fermented filtrates on second-stage juveniles(J2) and eggs of Heterodera glycines.The results showed that F-2、F-9 filtrates inhibited the nematode egg hatching by 95.67% and 95.17% respectively,it was extremely significant difference compared with water.F-9 filtrates were toxic to J2 up to 90% after 1 h.F-2 filtrates were toxic to 100% of J2.F-15 filtrates had no effect on J2.F-2 and F-15 were the same species,but had different effects. |
