Interactions between the entomopathogenic bacteria Bacillus thuringiensis and chemical pesticides used for corn crop protection is one of the most important factors that influence the effectiveness of the entomopathogenic microorganism. Bacterial biopreparates based on B. thuringiensis could be used along with chemical pesticides. The effect of chemical ingredients on bacteria viability is mandatory and it should be conducted first. Interactions between the entomopathogenic bacteria B. thuringiensis and chemical pesticides occurs when chemicals and bacterial biopreparates are applied simultaneously or mixed together. Selectivity on some biological parameters of B. thuringiensis was tested by making a mixture of B. huringiensis with chemical pesticides. Different concentrations of chemical pesticides were mixed with sporulated and vegetative bacterial cultures. The effects of chemical plant protection products on sporulation and vegetative growth of B. thuringiensis were monitored. The paper presents the results of experiments aimed at determining the influence of some chemical pesticides used for corn crop protection on the B. thuringiensis multiplication and sporulation.
