Two commercial products, Nativo® and Sphere®, recommended in Brazil for the control of fungus diseases in soybean culture, have been evaluated with regard to their toxicity on Beauveria bassiana. Parameter comprised the vegetative growth of the entomopathogenic fungus in BDA culture medium coupled to the addition of predetermined concentrations of the two fungicides. Initial concentration was that indicated to the culture field and followed by successive dilutions. Although both products were toxic to the fungus, variations in Minimum Inhibitory Concentrations (MIC) among the fungicides demonstrated that the degree of toxicity varied according to the dilutions. In the case of Nativo®, MIC reached 350 ? / L, whereas in the case of Sphere®, MIC was 2.0 mL / L. The former had a greater inhibitory power on the fungus than the fungicide Sphere®. Toxicity studies of pesticides to natural enemies have become important since new control strategies may be used in an Integrated Pest Management program.Downloads
