Abstract:
Two Bacillus BL-21and HNDF2 were isolated from recessive land of soybean cyst nematode in Heilongjiang province,the effect of their bacteria liquid and fermentation filtrate on cyst hatching and J2 were observed.There were 6 treatments including the bacteria liquids and fermentation filtrates of BL-21, HNDF2 and their mixture, respectively. The effect of bacteria liquid was better than fermentation filtrate.The mixed bacteria liquid of two Bacillus strains had best inhibition effect on cyst hatching and lethality of J2, its relative inhibition rate of cyst hatching were 80.93%,the corrected mortality rate of J2 reached 91.08%,which were significantly different with water control.Results suggest that the mixed bacteria liquid of BL-21 and HNDF2 had the best inhibition effect on soybean cyst nematode.
