The occurrence of the entomopathogenic fungi Metarhizium, Beauveria and Paecilomyces in soybean under till and no-till cultivation systems was studied. The number of colony forming units per g of soil and per cm² of leaf area was determined. Soil under no-till system showed a higher incidence of entomopathogenic fungi, but no difference in fungal density was observed on leaves. Thus the probability of infection for susceptible leaf inhabiting insects should be similar in both systems.
