Abstract: Synergetic application of dazomet and biological fertilizer were conducted to control celery root rot, and the control efficacy and the effect on soil rhizosphere microorganisms were studied. The results showed that the incidence of celery root rot of untreated soil was 29.03% after 60 days, the control efficiency of combined application of dazomet and biological fertilizer was 95.14%. After soil treatment, the variety and population of soil fungi and bacteria were significantly decreased compared with that of untreated soil, and with the prolonging of planting time, the number of soil microorganism increased to the level of untreated soil. The research suggested that dazomet could reduce celery root rot occurrence, its combined application with biological fertilizer could maintain soil microorganism structure and had important significance on the sustainable control of soil-borne disease.
