| Abstract: | [Objective] To explore effective drugs for the prevention and control of Phytophthora parasitica var.nicotiane.[Method] For comparison of Pythium oligandrum,dimethomorph and Metalaxyl.MZ to control the effect of Phytophthora parasitica var.nicotiane.[Result] The results show that EC50 of Pythium oligandrum is 0.113 μg/ml with determination of mycelial growth rate,contrast agents dimethomorph＇ s EC50 of 0.713 μg/ml.Field efficacy display that Pythium oligandrum showed good control effect （64.85％）,with Metalaxyl.MZ （65.35％） was not significant,and slightly higher than dimethomorph （63.85％）.[Conclusion] The Pythium oligandrum can significantly reduce the Phytophthora parasitica var.nicotiane incidence and disease index,and showed good control effec. |
