Abstract

The effects of the mycoparasites Coniothyrium minitans and Trichoderma harzianum, Trichoderma viride, Trichoderma hamatum, Gliocladium virens, Gliocladium roseum, Pseudomonas fluorescens, Streptomyces griseoviridis and Bacillus subtilis on the suppression of bean white rot caused by Sclerotinia sclerotiorum were evaluated in vivo during 2013. Results showed that soil drenching with C. minitans, T. viride and T. hamatum significantly suppressed the white rot disease incidence with 90% survival plants. In case of mixture, antagonistic fungi and antagonistic bacteria, the mixtures of T. hamatum+S. griseoviridis and C. minitans + S. griseoviridis completely inhibited the disease incidence that produced 100% survival plants when compared to controls.
