Efficacy of PRO-MIXReg. with biofungicide against root diseases caused by Pythium spp. and Rhizoctonia spp.

摘要

Bacillus subtilis MBI600 was tested in the peat based substrate PRO-MIXReg. BX as a biocontrol agent against root rot and damping-off caused by Pythium spp. and Rhizoctonia spp. The assays were conducted on two vegetables (tomatoes and sweet peppers) and two ornamental plants (cockscomb and garden balsam). Data obtained in this study demonstrated the beneficial effect of the presence of B. subtilis in PRO-MIXReg. BX. Damping-off and root rot were significantly reduced and root growth was significantly improved, resulting in healthier plants. Data from this study were used to support registration of PRO-MIXReg. BX with B. subtilis as a biofungicide in the marketplace to reduce root rot disease.
